@oscarvanegas63 we are a college, so we do. Personally I do not offer anything through this channel. We are located in Augusta, Georgia.

The engineering that goes into this car is very impressive. To me, it's fun to drive, sort of like a game (at least once the engine warms up). The most efficient traveling 'mode' is to be truly coasting, with your foot resting very lightly on the accelerator to prevent regen. That eliminates energy transfer, which is more efficient than regening the energy into the battery. You can do this a lot in city driving, such as coasting up to a red light that is 2 blocks away, if you are on a slight downhill which allows you to hold the speed of traffic in that 45mph or under speed. It's called pulse and glide. You use the engine power to get up to speed, then glide(coast). Driving with no foot on the accelerator will cause a small regen load (like engine braking in a normal car). This is fine if you need to get your battery charge back up. Many people think that driving in electric mode if best. But that is only true when the load is very low - such as in parking lots and steady speeds under 20mph typically. You only have a very small range in electric mode. The car is not designed for that. The ICE is most efficient under heavier load and at higher speed. The car's computers do most of this for the average driver, switching between modes without you thinking about it. But you can improve efficiency by minimizing time that either the ICE or electric motors are doing anything. Avoid drawing prolonged full EV power when above 15mph. It's really all about anticipating the next 5-20 seconds of driving up the road. No reason to go full speed up to a red light when you have to stop anyway. Often times you can time a light to the point where you can avoid stopping altogether. Truckers do this, because it reduces wear, less shifting and saves fuel. There is of course limits to this, you don't want to crawl at low speed with traffic behind you.

I find it amusing that my fellow Prius drivers frequently preach about not going to a faster speed than needed and coasting all the time to improve efficiency- while all this is true, why I find it funny is that the entire point of owning a hybrid vehicle is to mitigate these inefficiencies. All the advice we apply to hybrid vehicles are actually much more true for conventional ICE vehicles- since there is no regenerative braking, you better not be punching it in between stoplights. In a hybrid, while yes it is more efficient to use less power, it actually makes far less of a difference. Unnecessary acceleration and stopping will take you from like 50 to 45 instead of 30 to 15. The main difference is you want to make sure you brake very early so it's low torque and you don't engage the hydraulic brakes. You didn't buy a hybrid vehicle to use friction to stop like a caveman. Granted, the motors are more efficient at lower torques. But this mostly matters for braking, not so much accelerating, because when you accelerate it's primarily using the engine anyway, with the motors just helping out. You can see this if you install Dr. Prius and observe the battery charging/discharging current (directly proportional to power). Regen braking charges at up to 100 something amps (depending on battery health- mine's pretty old so it only gets up to about 80) before hydraulics kick in, stealth mode driving discharges up to a similar rate, but when you're accelerating with the engine it drops to more like 10A.

Hi, you're a genuine lecturer who're able to explain those very complex mechanical stuff in a very understandable laymen non-mechanic people like me... Thank you very much Sir. I have some questions base on your explanation; 1. The MG1 gets the power from 12v battery only. Not from HV battery. And MG1 would be the one which kick off the ICE using the 12v power. So in case the 12v battery is drained, we can do jump-start from another vehicle to kick off the ICE, right? Am I correct? 2. What if the HV battery is totally drained too, for eg. if we put the Gear at N for very long time and all the electricals are ON too, which end up both HV battery & 12v battery drain. If we just do jump start the 12v battery, will the ICE kick off back? (while the HV battery drains too...) Thank you very much Sir.

It transmits rotations like a differential, but the power split device uses spur gears (cylindrical) and a differential uses conical gears, so that the input and outputs can be at 90 degrees.

Very informative. I was under the impression that there was still a mechanical connection between the engine and driveline, and that there also was a transmission. So to an extent MG1 acts somewhat as a torque converter/transmission (OD as you say) when under acceleration-something I never realized.

@MadScientist267

Yeah same here and that was surprising/deceptive at first because the engine is running of course while they zip up to speed... I too did not expect *all* the power to go thru wiring before hitting the wheels. I'm assuming this is the "synergy" part of it... complete management of the energy

I own a 2013 Prius and another Gen 3 CVT that I invested in with the goal to make a 3-phase generator (alternator technically first and foremost) using a Briggs & Stratton 18HP opposed twin somewhat sentimental since was there hybrid car engine and I want to limit what power I can output in the initial design. Your video showing the demonstrator is excellent as well as your detail regarding how the engine, MG1 and MG2 function. I look forward to testing to see what the voltage and current profiles look like (Hz mainly) at the range of RPM's. Appears using the CVT without any custom fabricated MG casing (including with cooling unless I invest in another Prius-C CVT). My brake pads in the front are at ~260K miles and the rear most likely would have made as far though the passenger side lower caliper pin siezed and cause the pad to wear uneven so I replaced the pads... with amazement how the runout and thickness of the rotors were at worse 1/2 worn and at best 1/10th worn. That was at I think ~190K miles. I notice you say "stator" when I think as "rotor." Is that correct? Finally, do you happen to know what the frequency of the MG1 and/or MG2 (either one) is output? I'm guessing seeing the RPM and being 3-phase I can determine once I find out the number of windings... though I still need to study more since is I think an asynchronous alternator design being brushless. So will have those funky output variables without a load/resistance. I also want to make an AC/DC welder and seems a plasma cutter can be made from as well. These are the neatest to me and I am amazed the pricing since they last so long... that's nuts to me! Anyways, those specs for the MG1 or MG2 would be awesome to know since I'm wondering what the utility of the outputs will be as-is and then what all else will need to be made or used from the inverter/converter (I also invested in 3 more of those to have the parts since pricing was crazy on the half off self serve salvage yard days) to be more practical 3-phase (or single) 220 or 120VAC or maybe even 480-600VAC. If you know or have any reference, please share! Thanks again and awesome man! Very inspirational to learn to work on and seems like a great career.

Yes, notice that whenever the vehicle is moving forward, MG2 is showing "opposite rotation." But at the end, in reverse, the light is out for MG2. MG2 is directly connected to the drive train and will rotation 'opposite rotation' when the car is moving forward and 'normal direction' when in reverse, always. However, since MG1 works in tandem at times with the ICE, it can run in both directions. If the ICE is off and the car is moving forward, it more or less freewheels and rotates in 'opposite direction' is tandem with MG2. All bets are off so to say once the ICE is started because now MG1 has to have a relative speed to the ICE to control the ICE's rpms as well as starting the ICE. Coming out of stealth mode we see MG1 has to rotate in the normal direction to start the ICE.

I am owner of a 2023 Corolla with 5th gen of hybrid system and sure the function is the same. However I just wanted to ask you for a question. If driving with my car (with 140 HP) through a hill and the battery starts to drop down to that lower limit of 20% but I push the throttle as I need to overpass another car, is the system capable of providing the full power of the engine? Can the MG2 recharge the battery an provide power at the same time to make available those 140 HP or the power is lower?

When I got to the 3-way stop in Coudersport I spent a long time at a stop sign and that car kept turning the gas engine and stopping. Did it like 7 times to discharge the traction battery to a safer level. I'd never experienced that before and was concerned... "Shit! I owe a lot of money on this car... is it broken?" I drove another 60k trouble-free miles with it before a long legged woods rat leapt in front of me. Side note: That car's traction control system was all-the-bad! The slightest bit of slip and snow made the whole car give up on life.

@b43xoit

6 ай бұрын

I think his explanation is confusing. And I think "energy recirculation" is a method to get the effect of a higher gear without changeable gears. In a conventional transmission, a high gear allows high wheel speed while maintaining low engine speed. To do that with the Prius drivetrain, the control system has to shift energy via the electrical pathways. MG2 is connected to the wheels through a fixed-ratio geartrain. MG1 is on a differential between the engine and the wheels. Assume the battery is neither taking nor giving energy. What has to happen with the two motors? Talk about speed first, and from that try to infer the directions of flow of energy. MG1 has to add speed. Therefore, it also has to add power on the mechanical side. Therefore, it has to take up power from the electrical side. If we are not drawing from the battery, this power has to come from MG2. Therefore MG2 has to take up mechanical energy. It takes it from the ring gears, which are driven by the engine and MG1.

Huh. I have a 2nd gen Prius and I thought that when you let go of the gas, coast and not touch the brake that MG1 and the engine were applying that slight braking force, and MG2 only started regenerative braking when the brake was applied. I assumed this because when I had my catalytic converter stolen, I could hear the engine being spun by the engine any time I let go of the throttle. Basically a lighter version of B mode at higher speeds. And it would change again when touched the brake (though I’m 100% sure on that last one)

I also grabbed a few other parts to have on those half off sale days; inverter pump and washer fluid pump as well as an AC compressor.

Hi, this is an old post but perhaps I can get some technical questions answered. I swapped engines and transmissions as well as the inverter on top of the engine. I’m getting a red triangle as well as the lights as if I was out of fuel. My gas gauge works intermittently. My questions are this: is it possible that there is a ROM pack in the transmission or inverter that prevents vehicle from starting or is it due to the hybrid battery getting so low as to not go into “Ready” mode and start the gas engine?! My educated belief is that the Hybrid battery is too low since it sat for two months all winter in Canada. Other question is, if this is the case what is the easiest way to charge the Hybrid battery? Do I take it apart and charge individual cell packs with NiMh charger? Is there an easier way to bypass it and charge with something else? I have the old transmission and could build a until to spin the transmission and thus create a charger unit.

Hello there! Thank you very much for the useful video! I'm not very familiar with the hybrid cars and honestly wasn't really interested in them until recently. I have fully committed myself to EVs, and began to think about converting retro (and not so old) ICE cars. However after watching your video and a few others I began to think whether it makes sense to include in this group for conversion hybrid and plug in hybrid cars too!? They are after all half electric to put it this way. For example Toyota/Lexus have some models which have powerful enough electric motors to move the car on electricity only, in this case is it possible to remove the ICE from the car and use it as electric only? Of Course battery capacity has to be increased and few other changes to be made. My question is if this conversion makes sense, could you please point which models are the best candidates?

If a cell is weak you have a few options, depending on your skill set and time/money you want to invest. “Refurbished” batteries are popular, with many people selecting companies like Green Bean to come and replace your battery and offer a warranty. You can also remove the battery, replace the cells with new ones, and reinstall. I hope this helps, and good luck with your car!

I cleaned copper bus bars by sea salt and vinegar which helped eliminate the problem

What I want to know is the starting process. How does it turn the engine? I am working on a BMW X6 hybrid and I hear activity like turning as I press start button and transmission seem to be spinning but engjne is not being turned. It stay stationary, thus the car engine won’t start and car throws hybrid power train code

The engine is directly connected to the planetary carrier. To put any torque on the engine, it's necessary to hold the ring gear still and torque the sun gear. And what's the sun gear connected to? MG1, right? But that's the Prius. The BMV could be a wholly different story.

If I wanted to connect a solar panel to battery while it's running how many volts I have to apply to prevent overcharging? Since it's 7.2 v per unit so 28 of them will be 201.6 v. So if I apply 201.6 volts from solar panel will the battery be safe?

They are both submerged in transmission fluid for lubrication and cooling.

What happens if you put it in drive, full throttle, and then put it in reverse still full throttle. What will it burn out?

Pretty much everything about it is drive by wire or computer controlled. Even the stick returns to center when you put it in D. A thing that was missed in Gran Turismo. If you do that while driving, it does not do anything. Simple as that. Foolproof, in any way.

I had a Toyota Aqua rental car that did this after leaving the lights on, Just charge the 12v battery or jump start it. In some models the 12v battery is under the rear seat.

This trainer is the Gen 3 but shares the same technology. MG 1 and 2 will work the same.

I assume that MG-1 spins at 46,800, since it says: "X10"?

No way! Maybe 4,680rpm, 46,800rpm is getting into jet engine speeds, way too fast for anything mechanical

Oh wow. Didn’t recognize the engine without the blown head gasket

Toyota japan 😮

Gen 4 when you slowing down shuts engine off in any speed, unless battery overcharged. Even on flat road I can go in EV at high speed for a little. At least this how work with lithium battery, not sure if it’s same with old style battery. Gen 3 will drive in EV only under 45 mph, even if you go downhill, engine never shuts off, very little power. But I found if battery depleted, to recharge it, your average mpg will go down. Look like it better to keep battery not less then 70% charged. Needs to much energy to recharge. Gen 4 actually benefits if I using as much as possible battery power, much less energy to recharge it.

What is that chain drives.

The chains are part of the trainer and are not found on the drivetrain. Thanks for watching!

So the gearing is 20 mph per 1000 rpm as per a regular car? Why is the gearing not higher?

Thanks for sharing I have a Hyundai ioniq hybrid but I’m sure pretty much works the same way

@AUSTiNKiNSER

The ioniq hybrid works differently, the ioniq hybrid and plug-in ioniq only have 1 electric motor instead of two, and it’s paired to a conventional 6-speed automatic. So the ionic hybrid system is not as simple or as elegant, It’s able to de-clutch the engine, so that way I can run in EV mode similar to a Toyota hybrid, but it cannot create and consume electricity at the same time like a Toyota hybrid can. Due to only having one electric motor, it can either only create or consume electricity, it can’t do both at the same time like a Toyota hybrid can with having a two-motor/generator hybrid system.

Inpressive demo, however the engine and drivetrain is a Gen 2 version but the console is labelled Gen 3? Not a disaster in itself for demonstration purposes, but there are differences in the real world.

Because it's "different" and thus terrifying.

Your Engine RPM numbers were WAY off. Typically any acceleration at any speed (since it's an Atkinson cycle generator not a torque engine) will net 4200-4500 rpm with 80-90% throttle . At 22:45 in the video, you reached 90 mph...well I can tell you it's NOT doing just 3000 rpm to maintain 90 mph.

Toyota's hybrid car includes (Power split device + Generator + Motor) All three of these devices are assembled inside an iron block attached to the machine. If one of them breaks down, you have to disassemble the entire engine with this block outside the car and remove the block from the engine to fix the defect. Also among the hybrid components is what is called the power control unit, which contains the transformer, inverter, dc to dc converter and other parts, all of which are also assembled inside a block that must be disassembled to reach those parts. the power control unit requires a special cooling system other than the gasoline engine’s cooling system. Therefore, a hybrid car is expensive to maintain and allot of parts more mony for toyota.

Great video, but if you turn the car off, it’s not just gonna start up at anytime. You have to have it on, and that requires the key inserted, (or near car if smart key) and foot on brake while pressing the start button. They don’t just start Willy nilly.

I agree, I am not sure I see the need to disconnect the 12v Aux battery, unless you are disconnecting wires / risking a short circuit. There is still a lot of short-circuit current available from even a small AGM battery!

So if your big battery is completely dead and there’s absolutely no way to charge the big battery you can never start the car without buying the big battery or completely disassembling it and charging each and every individual cell

Came to this video to see if I can discover wether or not the 10,000 miles worth of oil life is actually more than that based on the % of mileage that was allegedly electric, but based on the trainer is seemed that the engine still is running most of the times above 30mph because it doesn’t know when it will be needed 🤔 If anyone smarter than me knows the actual answer that would be cool. In trying to learn if the recommended 10,000 miles for oil and filter change is actually overly conservative due to the hybrid nature of these cars. I run a Prius prime that claims ~75% of my drive was electric usage, so theoretically it would mean my engine is only getting “2,500 miles” of use if I understood correctly, but I’m way too sheepish to actually attempt to milk the full theoretical ~40,000 miles before an engine oil change would theoretically need to be done (assuming 75% electric usages and miles being done before time degrades oil integrity) Thoughts? Can a Rideshare driver get away with milking 20,000 miles before doing the oil and filter changes due to electric use and the engine being used less than what the odometer reads, or is the engine in fact being used for the full 10,000 miles as per the odometer and thus the oil change is in fact perfectly timed?

I change the oil in mine every 5,000 but that’s probably overkill. If you really want to get to the bottom of it, you could send your used oil off to get it analyzed. I’m thinking about doing this to compare oil quality.
