Can any of the US 50e owners run the vehicle telematics report as per the steps below? I am afraid that BMW is screwing us in the US again by putting a lower limit on usable capacity just like on 45e to make sure the battery can withstand the 8 year warranty period.

1. Log into https://mygarage.bmwusa.com
2. Go to vehicle profile.
3. At the top menu choose CarData and “Request BMW CarData Report”.
4. It will take around 24 hours to get generated. Just check in the same place for your CarData report.
5. Usable battery capacity is under “Energy content of the high-voltage battery” in the main HTML file of the report.

Thank you.

Unfortunately, based on my experience with 45e going that route didn't yield anything, see thread below. I'm capturing CarData report on my 45e monthly now, but it's all over the place.

It’s pretty consistent for me and some others. Anyway, it should be a good starting point for knowing 50e’s usable capacity in the US.

USA 50e usable capacity per advertising is supposed to be 25.7 kwhr yet BMW also says full charge should take 3.25 hours. Well 7.4 kw x 3.25 hrs is 24 kwhr. Doesn’t add up….

I ran a data report. Not good.


"Energy content of the high-voltage battery"- 20 kWh

Wow, that even lower than 70%!

I can’t believe it!

Ugh this is lower than expected and I am a bit pissed to say the least at BMW. I am buying an 80k plus SUV and expect to get the full capacity battery and I wish I didn't hear about this lower capacity... What is wrong with BMW.

the full capacity is 29.5kWh. BMW never claimed all of it was usable, just 25.7kWh. it’s only one report of 20kWh usable in the U.S. 50e, though it could be different (higher) for EU 50e but it’ll be a while until they receive theirs. as more chime in, we’ll get more definitive numbers.

You can be sure that regions outside of the US (except may be Canada) are getting 25.7 kWh usable capacity. That’s probably how this number came to be in BMW’s press materials. They probably made a mistake and put it in US press releases. That is not the only mistake they made - BMW USA website says that 50e takes 7 hours to charge in the 50e spec section even though on the main 50e model page it says 3 hours and 15 minutes. In any case, this 25.7 kWh thing is definitely false advertisement and might push BMW to either issue a software update or reimburse 50e owners in the US.

Did BMW ever release an official capacity number? The only thing I ever recall seeing is a promise of a 40 mile range which would be about right for 20 kwh.

have anyone charge their 50e from "---" to full? If so, you should be able to see how much kWh is used. Take that number x 0.87 = about the the usable capacity. 0.87 is because for my 45e, my average charge lost with L2 is 16% over 10 month of ownership. Meaning for every 1kWh used, 0.87 make it into the battery. Assuming L2 charging efficient remain similar, maybe this is another way for a sanity check.

Correction, I relooked at my average kWh used to charge battery from --- to full, efficiently is 87%.

My 2022 45e with 14800 miles on electric out of 23000 total has 15.92 kwhr capacity which at 75F will go 32 miles. So the 50e 40 mile BMW stated range with a 20 kwhr battery seems about right. Sure wish it really had the 25.7 kwhr available.

Also, with a 0.84 input to charge ratio, 3.25 hours 7.4 kw charging equates to 20 kwhr.

Also note that 45e’s 16 out of 24 kwhr is the same ratio as 50e’s 20 out of 29.5

yes, fr_tz did. used 22kWh to recharge 0-100% in 3h9m (posted via screenshot from his Charging history)

[fr_tz]

Here’s that screenshot

[fr_tz]

FWIW the Juicebox app says it supplied 23.05 kWh during that session. Juicebox app is terribly unreliable but thought I’d share for additional reference.

Yes, these lower capacities are very dissapointing. I expect it to be reduced but to 20 kWh seems a bit extreme. So I assume we are safe to charge the 50e to "100%" on a daily basis as BMW has already limited the available battery capacity??

That is approximately 80% of the 29 kwh total capacity for the car battery.

yes. that being said, the 50e doesn’t even have a setting to limit the charge level; it’ll always charge to 100% of its usable capacity

can’t calculate with the energy used to recharge as that includes charging losses. you must use the usable capacity which BMW labels as the “energy content in the high voltage battery” which was 20kWh at the time mobsync ran his vehicle telematics report.

20kWh of 29.5kWh is ~68%

[eelnoraa]

Putting 20kWh into battery require 23kWh from wall sounds about right. It is 14% lost.

If I grab all the 0% to 100% charging for my 45e from juicebox, the average 19.6kW. 13% lost.
