Most believe it is due to our longer battery warranty.

the U.S. DoE imparts a minimum 8y warranty on the HV battery (longer in CARB states). it is believed the reduction in usable capacity is to ensure the battery lasts that long (or even longer). to answer your question, it’s done similarly in the EU but their warranty length is shorter, so the reduction in usable capacity is not as much as the U.S.

in the case of the 45e with its 24kWh net battery capacity, usable capacity is reduced to 21.6kWh there compared to 17.1kWh in the U.S.

Just to chime in, as nZtiZia has mentioned, is it very important to have a 20amp circuit dedicated to charging if you want to charge the 45e overnight. I finally got tired of juggling where all my vehicles were parked overnight to share my Level 2 charger, so I purchased another Level 1 charger that could pull 16 amps for my 45e that is outside at night. Previously took about 18 hours to charge to full at 10amps. Now it finishes in 9 hours.

I didn’t know before that the included charger line with my new 50e could be a level 2, (with whatever the cost of the of that was) but, to me, it wouldn’t have mattered.
So, $1500 total…

that’s a ding on your CA for not letting you know its charging capabilities. you could’ve saved $600

still, don’t forget you may qualify for a federal tax credit on your charging station (Form 8911) to include the EVSE plus installation labor come tax time next year. I believe it’s a 30% credit up to $1000, whichever’s less.

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 if the report.

Thank you.

fr_tz, so did you get a chance to run the vehicle telematics report. You can follow the steps below.

could EU-based 50e owners also run a telematics report as well (if capable), so we can determine if there is indeed a difference in country-specific usable capacities?

I don’t think anyone outside of the US got their 50e yet.

we 45e owners had no choice but to buy a separate level 2; i have the JuiceBox (two, actually)

Maybe lot of new 50e owners are buying the adapter. Out of stock - will see when it actually ships. No worries though, my production was pushed back too, so nothing but time and waiting...

I went and bought a basic NEMA 14-50 plug based, 32A 240V EVSE on Amazon w a 2 yr warranty for a net price of under $200 so I could start charging right away. I expect dealer delivery this week - the car arrived at the Richmond, CA “port” on 4/28.
I’ll keep the BMW EVSE in the car as a backup and order the 240V cord - the NEMA 14-50 version, not the lower rated 240v cord.

Pissed about this since the standard equipment list for the 50e lists the Flexible Fast Charger as standard equipment, and all the online listings that BMW has list both level 1 and level 2 cords. So BMW created a hidden, crippled FFC for the 50e.

Class action ?

I just ran it and will report back tomorrow. I can understand how some may be upset with this but we’re really enjoying this X5. Really pleased with it and the power is just tremendous.

Batteries live and die by the number of cycles. One full cycle is from zero to 100%. If you can never fully deplete the battery because of the way things are programmed, each apparent cycle is less than a real one so it should last longer.

Since the US regulations require a vehicle HV battery to have a minimum life, to ensure that more reliably, BMW limits the actual capacity that is available. Europe tends to have a less stringent rule on battery life, if one exists, so it's safer to allow more of it as long as it lives past the warranty period, for the tradeoff of it typically not lasting as long.

Thank you. Do let us know as soon as you get the report.

I ran it and got the following-

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

Thank you! That’s even lower than 21 kWh we estimated.

Anyone using a NEMA 14-30 24AMP plug?

My new construction condo has this connection. Looks like BMW has the adapter. Curious if anyone is using this can what the charge times are like?

note that's the plug for a 30A circuit, so the max amps you can pull is 24A or approximately 5.8kW. divide that by ~22kW, you're looking at 3h48m charge time from 0-100% on a US 50e, BUT…

DO NOT USE THE INCLUDED FLEXIBLE FAST CHARGER ON THAT CIRCUIT unless you can limit its max amperage. it’s rated for 40A via level 2 and may draw 32A on a 24A circuit = risk for thermal event if the breaker doesn’t trip

But be very careful. The 50e flex EVSE will draw max 40A at L2 supply voltage, right? Even plug into 50e, it will dray to draw 32A, this will cause issue for your 30A peak/24A continuous circuit. Best case is it trips the breaker. Worst case, 32A is so marginally above 30A breaker, breaker doesn't get trip. Wire will get heat up enough cause more catastrophic issue. So don't use an EVSE with high max current capability than the circuit can supply.

If he sets the limit to be 24 he should be fine, right?

Yes, you are correct.

I briefly look at the manual of the flex EVSE, it seems only have only two options for current limit: max (40A), and 6A when limit is enabled. No intermediate setting. I could be wrong. Owner please chime in with correct information.

I was referring to the iDrive setting figuring that if it was set to 24 then it shouldn't draw more than that even with the flex at 40A.

I'm assuming that the charging limit menu range has been expanded for the 50e versus the 45e, but the user's manual I've looked at does not indicate that fact. In the USA, on the 45e, that menu limit only works on SOME level 1 devices. Level 1 is not the same as a mode used elsewhere to differentiate the different charging modes.

So, am curious how the menu interacts with the flexible fast charger when attached to both 120 and 240vac circuits.
