What time (hours) can you possibly extrapolate from this video? There is are obviously cuts every time the camera moves, plus arbitrary cuts and fast forward moments. Looking at the sun shining in the windows a very significant amount of time passes. Plus hourly rates are based on the time it takes the average experienced tech to perform a task. A “professor” is far from average.

Wow! Thanks, Professor Kelly. The safety and procedural details you provide will prove priceless for years to come to people who open these battery packs outside of an official Ford shop. The other Mach E battery disassembly I saw was destructive and not so detailed. I am very impressed with the effort Ford has taken to make these packs able to be serviced. Fasteners are all accessible, bus bars are covered and come out easily, cables and harnesses can be safely moved out of the way, etc. The ability to repair and restore battery modules without the need to replace the entire pack will extend the service lives of these vehicles. Not all manufacturers, as you know, make that a priority. This pack configuration also makes 'second life' use of these modules much more practical.

@@rondavis2791 In an interview before the Mach E went on sale, a Ford engineer said that the battery pack was designed such that dealerships could repair it. Professor Kelly's video confirms that the tools are available to replace modules. On the Munro Live tear-down we see that the individual pouch cells are spot welded to module busbars. From what we can see in that video it appears to me that individual cell pouches could be replaced, but it is very unlikely that Ford dealers would do that. Dealers are likely to replace any modules that fail, but this leaves open the possibility of aftermarket repair/rebuild options after the warranty has expired, like we see with Prius batteries today. Ford's use of modules also makes "second life" applications possible. Reusing batteries too degraded for automotive use for bulk energy storage is becoming more common as more EV batteries hit the scrap yards due to collisions or degradation. Even a degraded LEAF battery with only 50% capacity has more storage capacity than a $12,000 Tesla Powerwall.

We are all so incredibly lucky that you take the time to create these videos for us, Professor Kelly. Your value to the evolving community of technicians and diagnosticians is unmeasurable.

Really great content Prof Kelly. I did not realise it takes such a long time for the coolant refill pressure to settle out. Thank you for sharing. I am wondering if this means service costs for EVs are typically much higher than combustion engines. I always enjoy your presentation videos. Please Keep them coming. Kind regards Philip.

Regarding heat conductive epoxy and heat pad: The conductive epoxy can be made very thin, same as conductive paste, which is basically used to fill in the gaps of imperfections. You want the less material between the heat conductive metals, as any conductive epoxy/polymer is less efficient than any metal. The pad handles imperfections too, but has a "high" minimum thickness. If you have ever dis-assembled any electronic component that is mounted on a heatsink, you will notice that it can have one of 4 heat coupling options: heat paste (berillium or silver based), heat conductive epoxy (silver and or copper with epoxy), a flexible heat pad (like the one you shown), of a "rigid" heat pad (seen in high voltage insulation parts) The is a very nice video from Tech Ingredients about making and explaining heat conductive epoxies, and he even makes one with very excellent specs. Thanks a lot for all the explanations you provide us.

Yay, another video! We’re getting spoiled by all these regular uploads… 😁 I’m curious if cooling (or heating) both sides of the battery would be more effective. I’ve noticed on my Ioniq5, especially when fast charging, there can be a pretty significant difference in battery temperature depending on where the sensors are located (I’ve seen up to 30 deg F difference). It seems like cooling only from the bottom of the battery module would lead to a temperature difference between the top and bottom of the battery, which becomes more pronounced under higher loads (like a long/steep hill climb while towing, or DC fast charging). It also limits the speed at which the battery can be heated, since they can only heat from the bottom and wait for it to migrate through the battery, and it seems like the heating can’t be very aggressive (only about 95-100 deg F max from what I’ve seen) The Bolt can get away with less thermal conductivity between the battery modules and the heat exchanger plate since it operates under a lower load. 50ish KW fast charging vs 150ish Kw on the Mach-E and 160kw peak discharge on the Bolt vs maybe 350kw on the Mach-E GT. I’ve repeatedly DC fast charged my Bolt on record high summer days (peaked at 120 deg F ambient temp) and the car had no issue keeping the battery cool even after several fast charge stops. I never even saw any thermal throttling. If there is anything good about the relatively slow DC fast charging of the Bolt, it is that it doesn’t stress the battery. My Ioniq5 will thermally throttle a little during a single fast charge event on a warm (95 deg F) day.

Dear Professor Kelly, Thank you for yet another excellent training session. Very nice indeed. If the vehicle is functioning well and the coolants are at the right levels in the two reservoirs then is there any reason to change it. Eg it is filled for life (200,000 + km). As I understand it the reason here we changed the coolant was (1) for training purposes and (2) because we dismantled the modules in the battery pack. In an ICE engine in Europe we normally change the engine lubricant once a year or 20000 km whichever comes first but in the EVs the coolant, transmission and brake fluids are almost filled for life (10 years, 200,000 km).

@@WeberAuto Thank you for the info! This would make it a 2 day job. Too many YT commenters are wishing for batteries to be "repairable" either by their local "garage" or dealer. Based on ~$150 / hour shop rates that would be $1500 plus the cost of parts. The battery pack in this vehicle is ~ $24,000 and is expected to rise significantly, according to Ford. If one assumes that the battery modules inside are about 70% of the cost (i.e. $16,800) and then add the $1500 labor, it would cost ~ $18,300 to replace all the battery modules plus the expense of the special tools and fixtures. If these are amortized at 10% (i.e. $15,000 x 0.1) $1,500, then costs would be about $20,000, allowing for "shop towels and supplies" such as coolant, and assumes the other equipment, i.e. vacuum pump, are shop overhead. Of course, there would be the matter of the old batteries. Disposal fees for nearly 1000 pounds would simply add to the expense. This also implies that it could cost Ford > $1,000 to replace the contactor module. For 50k Mach-e cars... ~ $50,000,000!

Very interesting on how Ford has developed their hybrid drive platform, my boss just recently picked up his new Ford lightning I don’t know if you seen the underneath of that thing yet but you should check out the rear control arms talk about a ton of aluminum!

Prof. Kelly, what sort of connections are used in these coolant loops? Also does the coolant (in any of the cars you've showed) ever come in contact with live DC parts?

Curious... Correct me if i'm wrong of course; The BECM has balance circuits and would think it has an UN balanced cell issue if you disconnect the connectors in the wrong order.... I get that part BUT. Seeing that the BECM most certainly is a 12V supplied and controlled module, wouldn't disconnecting the 12V battery and disabling the high voltage system effectively make that BECM module dead ? So disconnecting it in anyway and order by mistake should not affect anything as its not powered up. I am all for and agree with the S/M, just curious as to why they chose to write it up that way. Maybe because someone will try and unplug it while still hooked up to 12v maybe?

@WeberAuto

Жыл бұрын

I do not know the answer. The 10 second wait time after disconnecting one of the connectors makes me believe there is a capacitor in the circuit; maybe for some sort of energy reserve. The BECM can get 12V from the high voltage battery by connecting wires across three cell packs. Thanks for watching

I’m curious what you think in here that is “designed to fail” that Tesla does better. Tesla is widely known to make things that are not serviceable, and the only vehicles they have made that are nearly 10 years old have had common major failures (batteries, motors, MCUs, lots and lots of door handles, etc). When those components do fail on Tesla, even if it is just a minor part within that component that fails (like a single cell in a battery, or a bearing in the motor), Tesla does not allow for any repairs, only replacement of the entire component.

This video clearly indicates that any future repair of this vehicle will be extremely costly. I do not see any way to recycle or dispose off these parts at the end of car life. Such cars will be extremely expensive to maintain and will create a major end of life dispose off problem. Any solution?

For recycling- throw the whole pack in an industrial shredder. Treat it as high-grade ore, extract the basic elements and manufacture a new pack and cells. Tesla has hinted this is their process for their latest pack design. On repair- a degraded pack could be repurposed for other uses such as grid storage before it requires recycling. This already occurs albeit not at large scale yet. Modern EV packs are expected to be good for 200k+ miles (up to 1 million for LFP!) barring any manufacturing defects.
