Dropping the VTRUX Battery Revealed SO MANY Hidden Surprises - You Won't Believe The Cooling System

[@agingwheels]

I see there's a ton of backlash over the sponsor in this video. I had no hesitation working with BetterHelp (and using their service) because they've accepted their FTC punishment and have changed their business practices, but I see many of you disagree with that. And that's totally fine! Disagree with me! We can all have different opinions and still get along. This was supposed to be the first of three videos sponsored by BetterHelp, but given the response from this video, I'm discontinuing that relationship. I just want to put out fun videos that entertain and (possibly) educate. I don't want to work with companies that are going to upset my audience or distract from the content. Lastly, I see y'all are claiming I'm deleting negative comments about BetterHelp. That's silly! I've deleted exactly one comment from this entire comment section, and that happened before the video was even public. I was on the road the entire first day this video went up. I hardly even looked at the comments, much less removed any. I welcome criticism about me or my sponsor. Say whatever you want! (just don't be mean, please. I'm sensitive)

[@Lizlodude]

BetterHelp is one of those sponsors that I'm almost more mad that they screwed up than the actual mistakes they made. Mental health and therapy are legitimately very important, and to have one of the few companies that is advertising services that aren't basically just selling questionable drugs go and mess it up is frustrating. I'm personally not comfortable sharing health info with really any online platform, and examples like BH's past behavior are a big reason why. On your part, though, the fact that you did your diligence to know what was going on with them and make your decision based off that is enough that I still trust your judgement, even if it may differ from my own. Even if other creators didn't know or didn't care about their issues, pretending they don't exist just gives more ammo to detractors and leaves a bad taste.

[@theotherwhiteguy]

Even if they accepted their FTC punishment, they still hire wildly unqualified "therapists" and people in mental health situations need a trained professional. To them, paying the FTC fine is just a business expense, not a lesson. I'm happy that you got the help you needed but it seems like your experience is the exception, not the rule. We weren't upset because the sponsor "distracted" from the video, we were upset because you were advertising for an unethical company.

[@TommyCrosby]

I agree that you have the right to like the service as much as you want, but I'm glad you followed the increasingly big request from your fans to stop the campaign. I'm saddened that people unsubscribed instantly before an official answer from you. I hope you didn't take it too bad or personally.

[@agingwheels]

@@theotherwhiteguy The correction I will add here is that they absolutely hire qualified therapists. Their hiring process was corrected something like five years ago. They even over-corrected a little. They now only hire licensed therapists, that have a masters or doctorate degree, and have at least 3 years of experience. Oh, and I wasn't saying you were upset because the sponsor distracted from the video. I'm fully aware of why you're upset by the sponsor. I was saying *I* was upset that the sponsor distracted from the video

My theory why the BCCM is missing on the truck might be because Via figured out the Peltier modules didnt do anything or not enough to justify the cost, so rather than change the mounting plate they probably already had stocks of they just looped the system and called it a day.

[@cortburris9526]

do you think they deleted it before production, or after they got this truck to replace battery module #4?

[@kgames9403]

@@cortburris9526 I'd think before. The van the other pack was salvaged from may have been slightly earlier production. Not saying it couldnt have been removed during the Via service but that seems shady if the customer was not informed of the removal. Hell for all we know maybe only the vans got the BCCM anyway.

[@haydenc2742]

Hopefully that burnt resistor wasn't part of the "balancing" circuit between the modules Seems like they would have some way to balance between them all, otherwise the balance issue will come back I wonder if a simple radiator assembly with a blower and a custom built shroud would allow "heating" for charging in order to prevent charging while freezing ah well...tons of work! Keep em coming!!!!

[@roboman2444]

The inability for the charger to balance the modules, or at least some connectors to the modules to do it manually without dropping the whole pack, seems like a massive oversight. On EVs, battery maintenance and longevity seems to be the biggest issue.

[@Transit_Biker]

The biggest issue is actually a combination of using the right charging method and thermal management. For many bev & phev you really should not rely on fast charging. Most plug-in hybrids can’t even do fast charging anyway. Level two charging is really the sweet spot for most of these vehicles as long as you can find a charger that works and fits along your route of travel. So really the two biggest issues are availability of level two chargers and making sure that the battery thermal management system is working correctly. In my personal opinion, fast chargers are primarily a good use case for people traveling longer distances in fully electric vehicles, and not local around town type travel.

[@markm0000]

This truck is a complete wasted effort. You can tell they really tried at first but became quickly outnumbered by incompetent investors.

[@Transit_Biker]

@@markm0000 the electric drive system is just not integrated properly with a throttle control for the gasoline engine. A few more steps and a little bit more time and investment may have seen these get much more success.

[@jacobcarlson4010]

To be clear, you’re not wrong. However, depending on whether those satellite boards had any logic on them (as opposed to being just a bunch of mosfets remotely controlled by the main BMS board), that idea might complicate the design significantly. For example, how many cells should be able to be addressed/used when balancing from one module to another? How do you balance (pun not intended) the workload of balancing the module itself as you’re also transferring energy out of it to a different module (this would be an issue when the cells within a module are mostly balanced, and bringing another module up would create an imbalance)? It gets pretty complicated in a hurry, so I don’t blame them for skipping that.

[@roboman2444]

@@jacobcarlson4010 True, but then, at least, have a diagnostics/manual balancing connector available. An un-balanced pack would still require a dealership visit, but significantly less work. All they would do is unscrew a waterproof cover, plug into a special charger, and let it balance for a few hours. Sure beats having to drop and disassemble an entire pack. These are supposed to be fleet vehicles, so ease of maintenance needs to be a priority.

[@LowTechFarm]

One of my neighbors has one of these trucks, and this has been very interesting to learn about. I'm intrigued enough that I may actually stop at his house and ask about his range and learn more from this person about the system and what they think about it. I had seen the badges on the rig and had figured it was a gm product not knowing it was a modified vehicle from a 3rd party.

[@markm0000]

I would put it all on black that he’s an electrical engineer and amateur mechanic to keep that truck working.

[@JayGroh]

If you want some good automated battery testers I use the EBC-A40L for single cell, EBC-A20 for ~0-18v cell or packs, and the EBC-B20H for ~9-88V packs but you need a power supply for charging with this model. I paired the EBC-B20H with a RD RD6018 power supply for charging. They all can be used without a PC but if you use a PC you can do more automation tasks and have graphs. The software can crash sometimes but the devices keep on going. I highly recommend them as they are cheap for what they do and they do it very well. I've manually balanced packs with these without issue but I also only use LiFePO4 and bottom balance and I dont use a BMS. You can also use them on other batteries like lead or if you keep an eye on them other lithium types or NiMh.

A123 Systems also made the battery pack for the Chevy Spark EV in the first iteration, which gave that tiny car almost 400 lb/ft of torque! Unfortunately they went bankrupt.

Your channel is a hidden gem, glad I stumbled upon it!

[@DrRChandra]

not sure about high capacity systems like this, but for run-of-the-mill batteries, never measure open circuit voltage. They need at least a slight load to get an accurate reading. Ideally, you measure the voltage while applying the load they're designed to drive, but a simple low wattage resistor (maybe 1/2 W) will usually do the trick. For example, I use a 39 ohm resistor for testing 1.5V cells, and a 330 ohm for 9V batteries. When the cells are good, the voltage dips a little. When they've seen better days, the voltage drops a lot, and usually drops by a millivolt or two per second.

[@bosstowndynamics5488]

Those are not lithium chemistries though. I'm sure LFP probably sag as well but they'll have a lot less equivalent series resistance than alkaline cells and therefore a lot less difference between load and open circuit voltage

But instead of peltier elements, you use resistors, which heat up too but are more reliable. When voltage is being applied for cooling, the diodes stop the current flow and nothing happens.

Thanks for bringing these repairs to KZbin! Very interesting!

[@SwordFighterPKN]

The factory replaced the cells without setting the voltages correctly? What a bunch of hacks

[@marsrover001]

You can charge up those modules much faster with something like a hobby charger that can do 8 cells at once. Make a balance cable to 9 alligator clip harness. This saves a lot of money compared to 6 dc power supplies. I like the icharger x8, it can also do reverse charging so you can load test and capacity test a battery very very fast. Not an ad, just my favorite tool when I'm doing battery repair.

[@iankemp2627]

They must've got a college grad to design that cooling system, because every electrical engineer worth their salt knows that the thermoelectric effect is rubbish for heat transfer efficiency unless the delta between the hot and cold side is massive (as in, hundreds of degrees massive). Evidently there was very little prototyping done before putting these vehicles into production, which is probably one of the reasons why they failed - a basic amount of focus group testing would've demonstrated the VTRUX is a product that not enough people want, especially at that price, to justify its existence.

A useful solution to the heating of the batteries in cold climates is a coolant heater, something that goes inline with the coolant system and can warm things up so as to stop stuff freezing (typically used as a block heater to keep an engine warm, though other block heater types exist that heat the oil instead), feeding warmies into the pack to keep it happy, but, erm, would require that loop to be unlooped, because that's just silly... :P

[@Jehty_]

But there is nothing to unloop that loop into.

Isn't it a good idea to get a LiPO/LiIon/LFP battery charger? Something like an ISDT Air8 can do 8s at a time and charge to any voltage you want. Such a device should be much more convenient than babysitting 6 bench power supplies. Heck, ISDT even make a 3000w charger that can balance up to 22s of LFP at the same time. That thing could probably balance this entire battery pack in a day or two.

bc-b20h or something similar from the same company. Can automate things and it's kinda affordable

Always good to see ya. Thank you your video quality is always great. Wish you good health, both physically and mentally.

[@olivercorrodi3340]

maybe the real range improvement was the friends we made along the way

[@ax14pz107]

Those peltier chips are amazing. We used them in an air lab to freeze VOCs out of a stream of air for testing. They cooled to a crazy low temperature in a crazy fast time frame.

Please get a better sponsor. Betterhelp is terrible. The amount of people I know who were matched with unsupportive therapists or even people with no qualifications is... unnerving. Completely unacceptable.

[@RoamingAdhocrat]

I have some shite multimeters and would impulse-buy whatever Robert recommended actually come to think of it I have paid for mental healthcare based on youtube recommendations - ADHD360 via "No Boilerplate". paid for an assessment but got derailed by the pre-assessment questionnaire so it's been on the back burner for... six months or so

I love these videos, not least because it's difficult to find a mechanically inclined car youtuber that both is so interested in EVs, but also able to explain things in such an understandable and entertaining way! Love your polestar btw, genuinely a dream car of mine. Being an owner of a Hyundai Kona EV, I'd love to see you tear down and check out a "proper" EV from a mainstream brand - a Kona, Bolt, or a Leaf and do something with them. Heck, the gen one Leaf, EV Spark, etc are all really cheap now, so maybe someday? 🤞 Hah, maybe you could take the good van modules and make an electric reliant! That'd be funny.

[@Derpy1969]

The A123 packs did cell balancing at 100% or 3.6V (ish). There’s a discharge resistor activated that prevents overcharge on the cells at 100% while other cells can trickle charge to 100. The problem is the BCM controls charging to the external DC charger or the on-board charger so it can properly limit current. How you do this without development tools, I have no idea.

Why didn't you do bulk charging of cells in series? There are also fairly cheap balancers available, or even full temporary external BMS with balancer might have been an option.
