2021 Model 3 Standard Range plus

[JayJayMDL3]

I have my 2021 MDL3 standard Range plus With only 50k miles I got this BMS_a066 Maximum charge level and range may be reduced Warning light on . SHOULD I BE WORRIED? Or Can anyone tell me more about it. I currently did my appointment for February 13 looks like i might be getting the battery replaced.

Well from what I have seen when looking up that error Tesla seems to be replacing battery packs for that.

Do you use Tessie or Teslafi or other monitoring program? How many miles does it say you get at a full charge?

If not you can sign up for Teslafi or Tessie and if you charge up once you connect it, it can tell you roughly what it thinks you battery health is at.

Did you schedule a service appointment?

That’s something new to me I’m Definitely going to check that out. At the moment it says 200 miles full charge

Yess but looks like they don’t have battery’s so I Have to wait until the 13 of this month just so they can see my car and make sure that’s wat it needs

I’m taking it yours was not the LFP but the standerd 53kwh pack? But was still initially rated for 260? If so that sounds like close to a 30% degeneration.
I’m Curious if you’ll be getting an LFP battery or if they’re still building the old style, standard range+ packs or if it’ll be a long range pack derated.

Yea Right now it’s just telling me “unable to charge - maximum charge level “ hopefully I can get a better battery, I work 3hrs away from home and I usually just go back on weekends but now a 3hr drive becomes a 5hr drive

i take it thats your original pack. thats bad but not as bad as i was expecting with what you where stating.

 

[Cachris]

Wow that sucks, only 50k and needing a new battery. Makes me worried about my battery, I have the same car but less mileage 32k.

Well good news is they cover it for 8 yrs 100k miles.

If it happens it happens but not every car will fail at same point.

It could have been 1 set got out of balance. I tend to let my car balance every sat to Sunday normally I turn off sentry mode when at my house so the contractor disconnects. And allows the packs to even out it actually made a 1 mile difference doing that in est range the 1st time I did it sadly I’m 3 miles under what used to be my max but am expecting up to 10 miles by the 6 month mark.

 

[pikapool]

Did you receive a comparable refurbished battery pack or a new one ?

 

[parafux]

Same to me. With 41000 km I got now the BMS_a066.
Tesla is looking to it in two days. In 3 days we wanted to drive to our holiday. Hope we get a free replacement car for the time. I don't know if they will replace the battery. Hope is guarantee.

Can you please define 'balancing'? I'm unfamiliar with what you mean by 'allow the packs to even out'.

Well somtimes batteries can get to the point some packs/modules having slightly different voltages for instance I believe the 3 has 3-6 modules inside the pack. Where one may read say for example 3.3 3.9 3.6 and 4.1 volts by letting the contactor to turn off the packs can self balance out to say 3.7 volt. (Note I realize the voltages are much higher talking at a cell lvl)

And in order to do that, you have to turn off sentry mode. And once the contactor is disconnected from my understanding they can then let the voltage settle and level out across the packs/modules.

but when it gets to the point he was at that is beyond any thing you could do to correct it. As sometimes cells have defects in them and they can cause an inbalance that the bms can’t even control or overcome except take the pack apart and find the bad module and swap it
