Model 3 SR+ Q3 2021 Battery Capacity

[jamespuk]

I know there are plenty of other threads discussing both how to calculate battery capacity, and on the new upgraded battery pack.

However: I have a SR+ with an LFP battery delivered on the 15th September.

My assumption was that this had the previous capacity battery.

However if I do the watt hours per mile (231) x remaining miles (212) / SOC (0.81) I get 60459 or 60.46 kwh. That would suggest that I have a larger battery….but the maximum range at 100% SOC is still 273 miles.

This doesn’t make sense. Have I failed at simple arithmetic?

Sorry, delivery 15 December, not September.

You do have a 60kWh battery. 270ish is the EPA (US) range and that is what the car uses. The ranges on the UK website are the WLTP standard which gives higher (and much less realistic) numbers for range. In practice, the actual miles you get will be even less than 270 which I assume you've already found - probably around 220-240 miles depending on how you drive, type of roads, outside temperature etc.

I think all, or certainly the majority, of Q4 vehicles have the larger battery. Certainly everything in Dec.

Do you have the V5 document yet? You should see E6LR as the variant code if it has the new battery.

I believe the 100% indicated range on the previous SR+ was around 255-260 miles. 270+ miles is definitely the 60 kWh battery.

My 55kwh LFP shows 262miles at 100% (even with aero wheel covers removed). I’m sure it was over 270 before I changed the wheel configuration.
But I agree the OP looks to have the 60 battery

I don't believe the wheel config changes the 100% range - it doesn't on my LR but I've seen mixed reports so possibly depends on software version.

I believe it is used in the Nav calculations though.
