MASTER THREAD: 2021 Model 3 - Charge data, battery discussion etc
- Thread starter EV Promoter
- Start date
It is most likely a switch from the Performance Motors (3D1/3D6/239KW) to the Base/LR Motors (3D5/3D7/208KW).
Seems to definitely be due to the motor change. UK customers are being advised that their Q4 cross over unicorn vehicles will arrive with the extra range from the new battery but the performance of the SR+ model they ordered because it has the old motor.
The battery for MIC SR's was LFP already so that can't be it.

TM3 LR Q4 2021 (after LR Q4 2019 and M3P Q2 2021)
Acceleration Boost in the past was always activated by "de-throttling" the 3D3 front motor.
This be a hard task without an actual motor in the front, but who knows... ;-)
Battery quesions for newbie
- I hear a lot of 4680 coming out of Berlin in a 6 months or so. What will that assumingly to do range, charing speed, price of the cars etc ?
- Elvissa really have patient and tried to teach me basics of batteries. I learned e3dl is the battery to pursue. Another person told me that there is difference between how much the Panasonic vs LG should be charged? The one only to 90% the other fine 100% contunuously?
Any insights ?

E3LD is the best of the current batteries when it comes to capacity and charging speed. The differences is not very big, so I personally do not think its an issue. If you can choose, get the 3L(E3LD). Otherwise, get what you get and be happy.
Theres not any direct difference between the Panasonic(E3LD) and the two versions of LG(E5D and E5LD) when it comes to charging levels.
Panasonic use NCA chemistry and LG NMC, I think. Theres theoretically some small differences between the chemisty but the short answer is that that behave the same when it comes to chargine levels.
No of these batteries is sensitive to be charged to 100%. They do not like to be at 100% for long times though. If charged to 100%, its a good idea to plan the charging so it is finished not too long before the departure.
If charged to 100% and driven down do zero they might hold for some 1000 cycles, thats 300.000km or more.
If charged and used in smaller cycles, they hold much longer.
Litium batteries doesnt like to stay for long with high charging level(SOC). They like lower SOC’s.
Lithium batteries preferes smaller cycles.
Lithium batteries prefer that the cycle is lower down in the SOC region.
Lithium batteries DO NOT have any memory effects, so they should be charged often(daily if possible).
For daily driving, the normal procedure is to not charge full(to 100% SOC) but to charge for what is needed plus a healthy margin.
50-60-70% is often enough.
Hi Guys,
Question: iI have been doing some calculations lately based on the % used and the Kwh consumed lately. All of the tests I did lead to the conclusion my 2019 M3P @ 48000km has about 65kwh usable capacity (left).
Yesterday, I charged to 100% (for the test), drove to relatives, stayed there couple of hours (no sentry! / app usage) and drove back. According to the screen i used 27 kwh in 42% which leads to -> 27÷ 0,42 -> 64.28 kwh capacity at 100% (of the 72 net it should have). Off course i could have had some drain while standing still, but not much.
Range @ 100% is 438km of the original 500.
I haven't supercharged much (about 7000-8000km of the 48000) and mostly charge to 80%. I make sure I never leave it at low or high SoC.
Stats from TeslaFi (I haven't had an account for all the Km's):
I find this quite disappointing, or am I missing something?

This is answered by energy screen method, but your vehicle BMS thinks you have ~67kWh (66.7kWh) left.
I think your calculations may have excluded the buffer, though I did not check them. It’s hard to predict from the trip meter if the trip is not truly continuous. And you should have used 27.2kWh. And it could have been close to 0.43, rather than 0.42. Etc. 27.2kWh/0.42/0.955/0.99 = 68.5kWh per the traditional method, FWIW. Not that far off, but the low SOC swing leads to potentially high error (~2%).
67kWh is slightly low but normal. 14% loss.

When will battery be replaced on guarantee within the 8 years. How lower capacity?

30% loss, and there is a mileage limit. Check the warranty.
Yes I know. Approx 192.000 km I think and 8 years.
Just wondering as I am about to buy one, if this is a worry point if I plan to keep for 3 years.
........Maybe I should just lease
