REVIEW | Hybrid Revolt BMS_u029 Reset Device for Tesla Cars

[@TeslaRacingandMods]

We live in a wasteful society, and we just dispose of things to fix our problems. Kudos to you for taking the extra step to prove how these companies take the easy way out! I'm also speaking as a Tesla owner myself.

[@TeslaMomUSA]

So true! I would prefer to get as much life out of my battery as possible- safely, efficiently, and as cost effectively as possible.

[@wickham53]

I agree with you, except that replacing the battery would not be a waste. Tesla will absolutely sell it to a company to reclaim the components. This does not in any way excuse them for not taking more time to solve the problem in a more cost-effective way for the customer.

[@TeslaMomUSA]

@@wickham53yes, I didn’t mean that the battery went to a landfill. I meant the Tesla service centers don’t repair the batteries. They sell you one, new or reman , give you nothing for the old one, then send the old one to their factory to be remanufactured and sold eventually to another customer for $14k or given to another customer free under warranty. Brilliant business model for them

[@GTOFan350]

What's the wasteful part? Li-ion batteries are over 90% recycled, all the rare earth metals are recycled, even the metal casing is recycled. The only waste would be transport but the same could be said about all materials that are recycled.

[@slartybartfarst9737]

Thank you for the concise analysis. Ive run a 2014 P85 Model S since 2015 bought new, now at 146,000 UK miles. My battery was replaced under warranty at 75,000 miles (coolent leak). Car went into 65mph snail mode, Tesla were exemplary, Freemont detected fault at 2am LA time organised new battery (reconditioned) job done in 2 days. I work with 186450 cells, totally understand why Tesla would err on the cautious side of the operating envelope given all the bad press of EV fires plus totally get why they just fit a replacement however I guess what we are all seeing is the evolution of the 3rd party battery repair industry of which the BMS reset device and your diligence to monitor the initial state and progression of state is so interesting to all us other "classic" Tesla owners, were all going to be at this point some time. Voluntarily staying away from Supercharging is a good idea for sure, I wouldn't be surprised if Tesla implement some software to detect a BMS reset and void Supercharging, got to have my shareholder head on. Either way it does not detract from an excellent idea to reset the BMS with a limited 8 cycles to one car with enhanced owner awareness, my guess is the weak link is us owners! But if I get the 029 fail Ill be straight after the BMS reset device like a shot, trying not to end up the weal link.

[@TeslaMomUSA]

I had to issue a correction regarding the 8 reset limit, my source was mistaken about that. It turns out there is unlimited resets.

[@chargepozitive]

Thanks for sharing your experience! I agree with you that it’s frustrating that the only solution they claim is to replace the battery at high cost to the user especially if it can be saved/repaired. Having 2 replacements under warranty was frustrating but definitely not wanting to deal with this potential out of warranty (almost to 120k miles now on my model Y).

[@TeslaMomUSA]

Yes it was a nightmare at first ! But now learning so much and it’s becoming more and more interesting to me. We will see what happens from here I suppose!

[@abarrera9176]

I applaud you on doing a cell balancing charge. Lithium batteries are like all other batteries. They will become lazy if allowed. Batteries that are always charger in a certain range, call it the exercise zone will over time lose charging area in the bottom and the top of the charge area. Think of it as burning a stick candle at both ends. This is especially common in lead acid batteries. Charging a battery with fresh electrons exercises the area in the battery being charged. There is a theory that teslas that aren't driven and for that matter charged regularly are more prone to failure. That could be. It's the same for car batteries. Over time the sulphuric acid in the car batteries will coat the lead plates. This is called sulphating. The battery will become resistive to accepting a charge as more area of the plates are covered. With regular use the acid will stay in the water solution instead of attaching to the plates. Battery companies like ac Delco and interstate remove new batteries from the shelf after about a year. I know interstate puts these batteries on special chargers to force charge these batteries aka cell balance them. Batteries that pass this are then sold as blem or reconditioned. So running a battery way down then charging to 100% from time to time can be good for longevity.

[@jonnymorrow5845]

Amazing video. I have the same car, same exact issue. Definitely looking into this. Thanks!

[@TeslaMomUSA]

Did it work for you?

[@LuisMadrigal-b8t]

Thank You! It worked. I did the Scan my Tesla, took pictures of the cells and emailed them to Matt. They look good. I bought the car at an out of state auction and I felt sick when I saw I could only get 75 miles of range. Super happy.

[@morgangitari8806]

How long has the fix worked for?

[@TeslaMomUSA]

I am glad it worked for you. The code returned one time since using the device right after I made the follow-up to this video (a little over 5 months since I did the reset.) I cleared it again with the device and no problems since.

[@918vgrega]

Hi Tiffani, why does it only work 8 times? How many times have you used it so far?

[@TeslaMomUSA]

I reset the BMS error only one time so far, and then immediately unplugged it. Im glad you asked this because it turns out that the device does NOT have an 8 time reset limit. I will be putting that correction in an edit.

[@NickLibert]

This was a GREAT video@@TeslaMomUSA I'm a few days behind you with my 2013 Model S 85 and am doing the same now--I believe it's tied just to our individual car and glad to hear it's not just for 8 uses. My imbalance was very low so I am pretty excited to be able to do this. thanks again!

[@TeslaMomUSA]

@NickLibert please let me know how it works out for you!

[@Babytoy2008]

It would make sense that if charged to 100% the battery BMS circuit can get shorted out.

[@tritiumrecords717]

Thanks for your video, yea I tried everything to reset the BMS but that Matt at revolt said it's a hard latched code, so with lots of kind advise I got the obdlink LX, the cable and scan my Tesla app I ran a BMS scan and he said my p85d was a great candidate with a 5 millivolt cell difference, he's sent me the said device, really hope it works. Can I ask how your car is doing, great video btw 😊

[@bocoffin5066]

Any luck?

[@TeslaMomUSA]

Thank you, my Vivienne is hanging in there at almost 185k miles now and it’s been months since the alert. It did come back one time since this I did the follow up to this video and I used the device again, no problems with the HV battery since.

[@moshekin565]

Hi why don't you show it in use plugged into the tesla?

[@TeslaMomUSA]

I did. I plugged it in during the video. Nothing else happened to show you than what is already in the video. It doesn’t do anything except clear the alert.

[@LuisDias-b7p]

First thank you so much for this info greatly appreciated it and great job on the research. I’m having the exact same codes a problem with my S model 2013. Can you lmk where I can buy the device please. I click on the link and type BMS u29 reset device and the HybridRevolt website and it says no product match. Again thank you so much and really looking forwforward to your response again great job and thank you again

[@joshuahuang07]

can you check the cell difference at < 20% SOC?

[@treborg777]

What is the difference between doing this & using the BMS reset function in the Service mode menu?

[@TeslaMomUSA]

The BMS reset function would just be like turning your computer off and on again. It will still have the alert code active. This device resets the alert code so that it goes away until it gets triggered again.

[@YourBestAuto]

Hello, I need a reset device, do you have?

[@Russell_L365]

Can you give us an update?

[@TeslaMomUSA]

Just posted an update!

[@bobbybishop5662]

Do they make those for cell phones ?

[@LuisDias-b7p]

Can you please tell me what app you use to read the battery cells please and thank you 🙏🏻

[@TeslaMomUSA]

Scan my Tesla

[@surfntrucks]

Tesla is leaving a lot of money on the table by not offering something like Apple Care. imagine "Battery Care" where you pay monthly for a higher tier of Tesla Insurance that covers battery replacement out of warranty.

[@TeslaMomUSA]

And then you’ve got EV manufacturers in China, Nio, with battery changing stations rather than chargers, where you drive in and get your empty battery switched for a full one . It would be great if this battery thing could be something like that. They get to keep the old one for free as it is, and then remanufacture it and sell it for almost full price? It doesn’t seem right

[@surfntrucks]

@@TeslaMomUSA Tesla had a battery swap location in California but Tesla claims a lot of people didn't use it. They went to the superchargers because they were free. Now the superchargers are not free so maybe Tesla revisiting the battery swap option might be a good idea? Or a 3rd party business can build a network of battery swapping stations? Make it a monthly membership fee so the company can stay in business and then charge a battery swap fee of like $40 to swap out the battery anytime you want.There is a company named ONE that makes batteries for Teslas already, this business could buy batteries from them. Or they can salvage batteries from wrecked Teslas to add to inventory. But the goal of all this is to make Tesla owners worry free about their battery because it would cost next to nothing to swap it out. I know a lot of Tesla owners wouldn't mind paying a monthly fee or subscription to swap out their battery.

[@PawelSromek]

Hi Tiffani, thanks for the interesting and factual video. Could you provide the exact name of the Facebook group you were talking about? I am interested in the topic. I send greetings.

[@TeslaMomUSA]

Yes, thank you for your comment. I hope the resources I added in the description can help to get your Tesla back in good shape 🙏

[@PawelSromek]

Thanks a lot @@TeslaMomUSA

[@BillyChansler]

I’ve been trying to get ahold of them to order but no answer any tips on getting ahold of them

[@TeslaMomUSA]

Join the BMS 029 Facebook group and post there. He’s in that group and I hear there’s other shops that do it now too but the people in that group can def help connect you to Matt or someone who can help

[@BillyChansler]

How is this holding up has the error popped back up

[@TeslaMomUSA]

I have been avoiding updates and Vivienne is performing perfectly. The error code has not returned since doing the reset.

[@fernandobravo2413]

Hey, I’m thinking about buying one of these devices. Have you had any problems?

[@TeslaMomUSA]

I have had no problems :) check out the follow-up I just posted for more details

[@rupertx3]

Probably have water ingress in the battery.

[@TeslaMomUSA]

That is very likely

[@AndrewRoberts123]

Uodate? How is it working long term?

[@TeslaMomUSA]

Hi! Thanks for asking, been meaning to do an update. But No news is good news in this case. I have put over 5k miles on the car since the reset and an OTA update and the alert has not returned! 🎉

[@AndrewRoberts123]

@@TeslaMomUSA thanks for the update! Working great for me as well! I am so happy and wish I had found this sooner. I've been driving with 70 miles max range for 2 years now 🥵

[@AndrewRoberts123]

Thank you!!! I found this because of you

[@beyerch]

Sounds dangerous.

[@TeslaMomUSA]

It might be! I guess we will find out

[@Renedue1967]

This is fake

[@LuisMadrigal-b8t]

It's not. If you have this problem, check with local shops to see if they can do the reset. I found out after I had ordered the divise. Here in Miami, EvGarage do them.

[@LuisMadrigal-b8t]

It's not fake. I didn't know but some shops are doing it (EVGarage, Miami). They check the battery, and if it looks ok, then they do the reset.

[@morgangitari8806]

@@LuisMadrigal-b8thow long has the reset worked for? Did you get this done?
