Killing the grid is one issue, ok electric cars are cool and all that, but as I see it when you buy one in 2020 you are just buying into more research, they aren't as efficient as they make out. It's down to two issues, the batteries are years of being as energy dense as they should be, and power generation at the ' other end' is not effective. Bird choppers or solar cells are expensive toys

Adding 3-5 cents a KWh is significant. Average price of electricity where I am is $0.16/KWh +5 cents is raising my electric costs by 30%, not "essentially unchanged". I can only speak to California, We cannot do any future proofing/upgrades without approval from CPUC, we have to write volumes of justifications on why we need to upgrade only to be denied and retry many times. This is largely political, but the utility companies are forced to conform. We are extremely reactive not proactive and it's by design.

"Having easy access to fast charging alleviates that fear...." The video avoids the central question - the future demand on the grid from DC Fast Chargers operating at 150 kW - 400 kW and/or the high cost of battery storage solutions trying to mitigate the demand charges. It is already starting to be a problem with 2% market penetration - higher rates for DC Fast Charging are inevitable as EVs become 20% - 50% of vehicle sales. No one is worried about home charging overnight so he wasted the vast majority of the video to a non-issue which isn't even in his central question.

DC Fast Charging isn't used all that often outside of Teslas, and that's mainly because those are so convenient to fast charge, relative to other Fast Charging methods. Most charging will take place at home and by the time EVs are cheap enough for 20-50% market penetration, batteries will also be cheap enough to justify having them at DC Fast Charging stations to mitigate those tremendous bursts of energy demand. On that note though, I do see a few possible ways that the effects of EV charging can be mitigated on the grid. If DC Fast Charging stations have a special pricing rate from the utility that can be updated on the fly, like every couple minutes or so the rates will change for purchasing electricity, then it would be fairly simple for the actual stations to limit the power being supplied, or draw more from battery backups, if the price of electricity goes above a certain value, then when the price goes back down, draw more power from the grid. This incentivises the fast chargers to draw less power when the grid is strained and more power when the grid can handle it. It would also be beneficial to have V2G capabilities built into future EVs. I know Chademo supports it, so it's more about getting more vehicles to support it as well. It might not work right now, as it does diminish the lifespan of the batteries, but if million mile batteries become more commonplace and batteries become much cheaper than they are now, it could be financially viable to keep your EV plugged in and have the grid draw power from the vehicle when needed.

Will those smaller wire (distribution level) be able to handle the increased load as the popularity increases? The cost associated with upgrading existing wires within as built subdivisions would not be cheap and would not be a cost any power company would be willing to do for free. Also the circuits feeding those distribution level wires are most likely at or near capacity now. Power companies are generally not inclined to over install wire beyond what is needed for an area to use. More breakers and substations would need to be built and additional wire brought to areas of high charger usage. Time of use helps if people were to trickle charge overnight, but if people are charging their vehicles midday while cranking up the AC, the generation and transmission might be able to adjust but the distribution level probably won't.

There is a way for grids and fast charging to complement each other, at a cost of course. That cost is not necessarily monetary. Grids have used load shedding for decades, or in other words the grid operator and utility companies have the ability to throttle down demand from a select few high usage customers. This normally occurs only a few times a year for each large user. Fast charging stations would be a prime candidate for such load shedding, so perhaps an EV would charge normally in 5-10 minutes, but a few times a year might take 20 minutes.

For people that park on the street, there are multiple solutions. In single-family home suburbia, the simplest solution is to just get a long extension cord to connect the car to a level 1 or 2 plug on the outside of your house. For most people, that's good enough. The more crowded areas where parking in front of your house is likely to be taken tend to be walkable neighborhoods, which means there's probably a pay lot somewhere nearby with a charger. So, every few days, you just park there, plug in, walk home, go to sleep, and come back to retrieve your car the following morning. For people that live in apartment complexes in unwalkable neighborhoods, there is, unfortunately, no good solution besides the landlord's willingness to install chargers on site. The good news is that level 1 charging is cheap to install, and could be paid for with government incentives.

As more & more EV driving is adopted, the plan around the world, along with the use of smart chargers, is that EV's with be used during peak demand periods by feeding a small amount from each plugged in EV to balance the load, thus reducing the need to have inefficient power stations on standby, which is presently used during peak demand periods. We are along way from that, especially in North America but that is the long term goal.

It is a much different story in the UK, the loss of heavy industry here leaves us with spare grid capacity even at peak times (3pm - 7pm weekdays), and there are already many electricity tariffs that incentivise charging your EV outside of peak times. In fact one Time of Day tariff has already PAID consumers to USE electricity five or six times already in 2020. We have a single company that manages our whole grid, and that company is looking forward to more EV's being connected, as that will help them smooth demand through the very variable day / night peaks and troughs. I believe that many European countries are in similar positions, southern countries have huge amounts of solar energy spare in the day, but little at night, windy countries in the North often have spare capacity at night and in the middle of the day. Superconnectors across Europe help balance this demand.

Matt, when we switched between leaded and unleaded the gas nozzles were different diameter and I believe diesel is also a different diameter. It’s fairly good analogous to what we see with EVs.

The current problems facing electric vehicles, such as lack of charging protocol and infrastructure standardization across companies and nations, are solvable. The problems aren't really technological in nature. The problems are caused by lack of standardization, which is a consequence of lack of appropriate forward thinking, organization, and cooperation by humans. Humans can get organized and cooperate with each other, and sometimes they do. Therefore, the problems are solvable. Internal combustion engine vehicles rely on crude oil. Crude oil reserves are a depleting resource, and well before they actually deplete (in full), crude oil prices will greatly increase. Depletion is not a solvable problem. The only viable long term solution, is to stop relying on crude oil and other consumable/depleting resources. Renewable energy and increased recycling is the solution. The only other option is to do without (deprivation). In the future, what would you rather do: drive an electric vehicle, or walk around with a backpack and handcart?

I would also add that for example, the state of California consumes an immense amount of gasoline per year and if one calculates the electricity needed to produce it, that would be a huge amount of power that could be saved and used to charge EVs. Taking a look at data from 2015 per: ww2.energy.ca.gov/almanac/transportation_data/gasoline/ California consumed 15.1 billion gallons of gasoline. Data from UN Statistics division indicates that refineries use approximately 4.5kW of electricity to produce one gallon of gasoline. Multiplying 15.1 billion gallons X 4.5kw = 67,950 gigawatts that could be added to the grid to charge EVs.

Matt, GREAT summary of EV 101 but more importantly the education of vehicle to grid (V2G) and how EVs will be leveraged to bring forth the #EnergyTransition to the grid 2.0. Thanks for your continued delivery of solid content.

Thank you for your overview of the different charging connectors. It is fascinating to me that the very same group opposing more new "non renewable" electrical production capacity is the very same group promoting EV's. I do see battery storage helping to address the issue. Like so many others you do NOT address the segment of the potential EV market, that of commercial vehicles (trucks)and construction equipment, which will consume MANY times the KWH's and will ramp up much more quickly due to lower repair/maintenance costs thus an overall lower cost of ownership. I believe the grid will grow to meet demand but we are going to have to see a new approach by the electric utilities to change the attitude of the general public. Imagine the substation necessary to power up a Tesla truck stop!

That is a common mistake. The battery stores energy. Energy can be measured in various units, for example Joules. Power is rate of delivery of energy. It is measured in watts, which is one Joule per second. An engine which delivers 200 horsepower delivers about 150 kilowatts. If a charger provides 5 kilowatts of power that means it is providing 5000 Joules of energy per second. As soon as you plug it in it is immediately providing 5 KW. The longer you transfer energy at this rate the more energy you get. The confusion is that if you multiply power ( Joules/second) times time you get energy. Battery energy capacity is often expressed in “kilowatt-hours” (kilowatts multiplied by hours, not kilowatts per hour, which would be kilowatts divided by hours), which is the amount of energy you get by charging at a RATE of one kilowatt for one hour. This is about 3.6 million Joules. Saying “kilowatts per hour” is like saying “kiloJoules per second per hour.”

Kilowatts are a rate of energy consumption, equal to 1000 Joules per second. Joules are a unit of energy. So kilowatts are energy divided by time, like speed is distance divided by time. Kilowatt-hours are a unit of energy obtained by multiplying power times time. So if you are consuming 1000 Joules per second for an hour you are consuming 3,600,000 Joules or 1 Kilowatt-hour. Just like if you drive 60 miles per hour for a week you will have traveled 10,080 miles. Or if your shower consumes 2 liters per minute and you run it for an hour you use 120 liters of water. Kilowatt-hours are a unit of energy and have nothing to do with rates of consumption or rates of charging. It’s unfortunate confusing terminology.

In S Korea (since 2017 I believe) industrial standard is set to J1772 for level 2 and CCS 1 for DC fast charging, which follows US.

Yeah it’s probably a good thing that it’s a slow change to EVs. A fast one could cause some serious issues with the grid. The idea of having a smart system that talks to the grid and balances your needs vs demand and timing is a good idea though. But it’s almost like you need to be able to express your intentions to that system as well. For example you might normally only drive to and from work and not even need a full charge, but then randomly one day you could plan on driving interstate. If you can communicate your intentions then it could know to not even bother fully charging your EV if you don’t need it fully charged in the near future (fully charged batteries reduce the lifespan of the battery too) but then when you need maximum range and you plan on leaving at 5am to get to your destination, you don’t want it to be holding back charging when you need it. So it’s not simply a case of software figuring that out, when some variables are only in your brain. They need a way of communicating with the system as well. And even just communicating your battery percentage as well. But that part should be doable. Behavioural analytics can predict that you might only need x distance by y time etc but not in every circumstance.

Agreed. The EV owner must always have manual override capability, so as to opt out whenever needed, of any utility managed time/rate limited charging schemes. There should also be some financial or other reward provided to EV owners for when they do opt in, so as to get people to voluntarily do it, rather than to try to force things by some kind of draconian/hostile/evil/"one size fits all" (even though it doesn't) government or utility mandate. A few people occasionally charging their electric vehicles at a fast rate during peak hours does not destabilize the grid. The grid only gets destabilized when a large number (or majority) of people are routinely doing it.

Informative video. People need to understand that the grid is and has to be designed to handle the maximum peak load (including seasonal variations). The peak is normally around 4-8pm its OK as long as most people charge their EV's either at night or during mid day when there is a lot of extra solar (if you live where there is a lot of solar).

Alas, false. Perhaps in the US, but US != world. Much of the world is built to be "good enough" not continuous throughput. That is, you can overload equipment for several hours per day at the peak and it will cool during off-peak. Build to peak would be much more expensive. Much of Europe uses this method, allowing assets of 0.75 x peak to be used. Really. EVs and Heat Pumps (EU homes have no HVAC) mess with these design approaches. Reports suggest that, today, c. €880 bn. needs be invested in upgrades across the EU. BTW there is no one thing as "the grid". It is many parts with many point limitations.

Fun fact: there is no such thing (yet) as level 3 charging. There is level 1 AC, level 2 AC, level 1 DC, and level 2 DC. The SAE standard has level 3s left as To Be Determined (not a standard yet.) Someone saw level 1 and level 2 for AC, and assumed the higher power DC fast charging meant it would be a level higher, and somehow that became almost ubiquitous in ignorant colloquial usage.

Adoption of EVs will naturally reduce ICE vehicles. This will cause a decrease in oil usage. Oil refineries use an immense amount of electricity compared to EVs. It will actually be far better when EVs are in use due to this very reason.

"We didn't used to have gas stations" - yeah, but that was an easy solution. Have you ever seen the amount of solar panels to allow 50,000W of power? 125 400W (6' x 4') panels.

And for that Germany, Japan, China, SKorea are investing in Hydrogen. They dread the nightmare of everyone charging E-cars, they want people still going to pump fuel and be free of battery, no need for more generation and investment in grid and keeps the infrastructure and industry jobs of ICE cars.

My issue is the costs and loads. I'm also in MA. I have 9,945 watts of solar on the roof. We've reduced the home's electric needs so that we've not seen a positive electric bill since 2015. I just completed some calculations on what an EV would add. My electric rate is roughly $0.33 per kWh. This includes the rate, delivery services, and the flat fee averaged over a year. (National Grid charges a flat $7 a month just to be a customer) It's very likely that an EV would result in an electric bill. While we typically have a credit roll over in March when the system begins producing more than the house used, it's not much. As we are an active family, I was looking at the new Rivian R1T which is a larger and more thirsty EV than is typical, but even when I ran the numbers for other options like the Ford Mustang Mach-E, the numbers were not all that different. Assuming a 100% power efficiency (which is never the case) gasoline prices would need to be in the $4 range to make the Rivian cheaper to operate than a Ford F-150. While the Mustang is a bit better at about $3.40 that is still higher than we are currently paying and prices only recently spiked. But the other thing that I found shocking (pun intended) was that given my typical mileage, adding the Mach-E would effectively double the power use of my home in a typical year. The Rivian would be about 30% more than that. Our household is actually well below average with roughly 24 kWh per day average. The national average is about 30 kWh. If you had households adding EVs at a significant rate, it would be like adding a new household to the grid at an alarming rate. Given the delivery charges that exist today (those charges are higher than the power rate itself) I don't see the northeast growing the production side as fast as many politicians are talking. With EV "mandates" and manufacturers talking converting to all EV by the next decade, I wonder where this power would come from. A good majority of the households in the Northeast are also multi-car families. You not only run into the issue of having households suddenly using the power of 3, but also seeing overtaxed electrical services. I already know a couple people who had a second 200 amp drop put in their garage just to have 2 60 amp circuits for EV charging. There is NOTHING in the average household that draws power like an EV charger. Sure your hot water heater or electric stove, and even electric dryer run on fairly hefty 240v circuits, but even when those are running, they don't draw maximum current for very long. With an EV, the potential to draw 48 amps continuous from 20% to 80% charge exists. In reality I suspect that thermal issues with the AC/DC converter does not allow that, but I don't see any reason why as the technology improves it does not become more efficient and sustainable. Speaking of efficiency, I could not find any reliable numbers on the charging and usage efficiencies. Some were as high as 98% which seems unlikely, and some were as low as 80% which also seems off to me. But to keep the math easier, lets assume that from the time a watt passes your home's meter to the time it is put into doing work on your EV, there is a 20% loss. You just added enough overhead that the average EV used by the average driver is now using slightly more power than the average US household on a daily basis. I understand that at night, the commercial use of power is much less, so there is more to supply that added load, but is the transmission structure able to handle double the current household loads at night for all those 2-car families? I suspect that the "cheap" night rates will no longer be as cheap. And then you have all the issues with urban charging from apartment complexes to all the on-street parking that currently there is no solution for. You can be sure that whatever solution occurs there will end up costing the consumer more than just the cost of power. The desire to switch from a gas to electric would slow even more in that scenario as fuel costs would need to be even higher to justify it. One saving grace to this whole issue is that the average car on the road today is about 12 years old. So, even if every car sold was suddenly an EV tomorrow, it would take over a decade just to reach a 50% EV density. I suspect due to the infrastructure and cost barriers the 50% saturation is going to take much longer and 30 or 40 years is probably more realistic. And I haven't even addressed the technical challenges on the vehicle manufacturing side. A lot needs to be addressed. Power generation, power transport, home electrical loads, time based load balance, and more. Sure, these are all solvable, but they require a lot more dedication than we see today. I'd love to see the kind of push we see for Solar and Wind be put into something like Thorium salt reactors. Imagine being able to put a safe clean power plant in a major city. It greatly reduces the transmission costs and power costs. But alas far too many people's thoughts of nuclear are stuck in the 1950's.

In China AC Charging is done with the type 2 layout but with some changes. The plug is male and the vehicle connector is male too. The plug has an mechanical lock like the type 1 (J1772).

Frequency sensing is not bad but really I want a price signal so I can choose when to charge my car and when to sell solar power based on the price, and I want to express my demand in advance so that utilities can better choose which plants to power up and when, or match my demand with a neighborhood power generation source like solar. It seems beneficial to electric utilities and the environment to make it so that utilities can match more local generation and demand, using their distribution and transmission networks at a higher capacity without building out a ton of new generation.

The great majority of EV owners will charge overnight when the grid is underused. The Utility companies are extremely happy that their excess power will be used. Some may provide a cheaper power rate for EV owners if they ask for it. Each EV takes up an average of 8 kw per hour, about the same as a small air conditioning unit.

Maybe by the time the grid upgrade costs start the EV purchasing costs will have dropped enough that we will still come out ahead of ICE vehicles.

The level 2 charging most people will use at home bears describing in a bit more detail. The maximum kilowatt rating is a function of the size of the circuit breaker on a home service panel (4.8 to 19.2kw) in combination with the maximum amperage of the EV's internal charger.

We shouldn't have to make any major modifications to the grid here in America due to electric vehicles, because as more electric vehicles enter the market, there are other people or same people, who are installing solar panels on their house, which increases the production of electricity as well. As a rough guesstimate I would say that solar installations outpace EV adoption at least for the next few years.

The Wallbox bidirectional charger sounds pretty cool -- especially if there is a significant difference between electricity prices at different times of the day. I guess you'd have to do some simulations, but in certain cases it might be more cost effective to just by something like the Wallbox and an EV that doubles as a home battery than to buy something like a Tesla power pack in addition to an EV.

EV's are, until further developments, a niche segment of the car market heavily dependent on taxpayer subsidies to make them attractive to car owners. For most Americans, EV's are simply not a practical transportation option - not to mention that most Americans simply don't want these cars in the first place, even with the range and charging issues solved.

There’s an interesting topic there to explore. Most EV charging stations are unmanned, so if something is wrong/broken ... it can really be frustrating.

In good part I think Texas answered this question, along with several thousand useless frozen windmills. One thing for sure Tesla will have a solid used car market from now on.

It showed that gas powered cars were as vulnerable as EVs. Gas pumps need electricity to work.

Dude you live in a bubble.

Thanks for covering the challenges, the solution to which all seem to be at some uncertain time in the future.

As I understand it EV batteries charge at different rates, depending upon their charge level. In other words a less full battery charges faster. I had a pickup truck with two fuel tanks. Why not split the EV battery. You could charge only the more empty half faster or charge both at the same time.

6:50 correct me if I am wrong aren't the new Teslas shipping with CCS2 ports or is it an adaptor for those chargers?

Thanks, Matt does the fast charge back to slow Fast Fast slow slow slow Fast slow effect battery life, build up heat, and the like?

EV's are essentially like your mobile phone--the (proprietary) charging cords are one of the many weak and links with same annoyance factor.

How about the effect of solar windows installations on the grid plus electric cars? Companies like solar windows are going into production in 2020 turning high rise buildings into power stations.

can 3wheel e trike be charge at normal charging stations

In Europe we basically are about to make ccs as the standard, can give any kinds of power, and in its next generation also take power back to the grid like the chademo. The good thing with a Tesla is that it can charge on 3 phase, one phase and everything in between on the type 2 cable when not quick charging.

Undecided with Matt Ferrell listen go to the pod now, one thing, energy in a battery is kW/h, power is kW. It’s two different things. If a charter gives 150kW you Could charge a Tesla 3 in 30 min 150kW 1h is 150kW/h /2= 75. Cause it doesn’t work that way with dc, losses and charge curves and all. But please separate kW/h and kW, it’s two different things even though they are confusingly similar. Other than that love the work

I was thinking the other day it would be interesting if everyone had electric cars and they were used to store power from solar or w.e instead of building massive dedicated battery banks... but then your car would never be fully charged and could potentially have very little charge in it when needed and no one wants that.

Modern Tesla and other electric vehicles commonly come with 60 kWh or larger battery packs. The majority of people drive less than 50 miles per day, which for a vehicle like the Tesla Model 3, consumes around 13 kWh from the battery pack. If one also wishes to maintain at least 20 kWh minimum additional charge (ex: enough for ~75 miles) as bottom end buffer, then theoretically up to 27 kWh would be available for vehicle to grid purposes. This is quite a bit of energy, more than enough to meet 100% of the nightly average US residential household electricity needs (as the average household uses ~30 kWh/day total electricity on average, with half or more of that during the day). Additionally, many electric vehicles sold today come with considerably larger battery packs (ex: 80 kWh to 100+ kWh), so assuming the same 50 miles/day driving + 75 mile minimum reserve, would potentially yield upwards of 47+ kWh available for daily vehicle to grid renewable energy storage purposes. In practice, owners of such vehicles may not necessarily wish to allocate such a large amount of vehicle battery capacity for grid energy storage purposes. However, when owners of such vehicles get adequately compensated for providing vehicle to grid energy storage services, I suspect plenty of people would in fact be more than willing to do so, in an amount at least equal to their own nightly residential electric energy usage levels. In other words, using long range electric vehicles as distributed utility scale batteries, is in fact quite viable, realistic, and practical. However, in order to actually be realized in a cost effective way, the electric vehicles must be manufactured with high cycle life and/or cheap to manufacture battery packs, such that the cycle life wear out cost of the batteries is less than the compensation that EV owners receive for their grid energy storage services. In other words, it must be profitable to the EV owner, to allocate battery cycling wear and capacity towards grid energy storage. Currently available lithium iron phosphate batteries do provide excellent cycle life (some models claim >=10,000 cycles at 80% depth of discharge) and sufficiently low overall cost per cycle, such that they can meet this requirement.

Because of the differential charging times for PHEVs, BEVs, various ranges, and because a big chunk of the population will be able to charge at home, the solutions are going to be a lot more varied: the gas station on the corner model will no longer be ubiquitous, because people won't want to plug in and wait there, or plug in and leave the car. Destination charging like hotels and homes is going to be a big part of the distributed solution.

Nice video but doesnt really explain how the grid will handle it :( Expected something else from the title

The problem is when use grow population grows but grid and power genators don't grow is problem in Texas. States that are shrinking there is little incentive for upgrading. I have campground I have lot meters so if you plug in I will charge you. But places who don't have park owned meter this will cut in their profits. How long will your model s run your home in a outage

The adoption rate of solar and other renewable energy should be considered. I think the local monopoly’s and the grid should be a thing of the past. Power lines make natural disasters more dangerous, and unnecessarily put thousands of people in the dark.

How is Tesla doing on integrating solar with their superchargers? I would like to know more about that.

@garethbaus5471

I don't know how they are doing, but it wouldn't be particularly hard to add a few panels to help supplement the energy usage it probably isn't practical for all of the power to be generated on site though solar is most affordable when you don't need to buy dedicated land for it or if you at least stick with low value land.

Great explanation of all the charging standards and speeds. We'll probably see Tesla make a CCS1 to Tesla adapter in the USA sometime soon.

Let's as those who live near Fukushima how things are working out for them?

IMHO, the concept of adding batteries to DCFC systems are a nice alternative, but they increase the capital needed to an already expensive endeavor. Livewire has such options. We have about five Livewire DCFC in the Charlotte metro area. They seem to have a solid solution to defeat peek charging costs, but their products are more expensive.

Manufacturers can fit different sockets on the cars. For instance in Europe Tesla model 3s have the CCS 2 socket

What about electricity prices ? Will they go up as a way for a road tax in a way? Where I live prices up just in the last year 9-13C to 10-20C

Actually, many (if not most) states are now charging a registration surcharge on EVs to make up for lost fuel tax revenue. Here in Wisconsin it's $100/yr, which I feel is reasonably fair (by comparison, we originally replaced a Toyota Prius with a Nissan Leaf, and the Prius paid $68 in gas tax in a 15,000 mile year.) Other states have gone nuts - in Illinios I think the surcharge is $250/yr, which is just way out of the range of fairness.

No. Lost fuel duty will be replaced by a system of road tolls. The details of which are currently being discussed by the Government, major motoring organisations, and others...... Electricity prices cannot be artificially jacked up as a tax, because hospitals, schools, industry, care homes, and millions of people use it to cook and heat their homes. It would simply wreck the economy and put thousands more people into fuel poverty. It would also spell political suicide for the Government who chose to do it..... If you want to pi$$ somebody off big style, hit them in the pocket....

There should only be one type of port. Maybe ansi or ieee should define a standard. Given how it is now there should be adapters to be able to hook up to any port. The differences should only be at the software level.

cali already can't provide customers notice before rolling blackouts, how could the grid possibly handle the ev increase if it can't handle its current rate

Careful with units, Matt! At 4'24" you say Level 2 Chargers deliver at "10 to 20 kW per hour". kW and kWh are not the same thing, as you know.
