Has anybody with a Model S or X 75 kWh battery ever seen a charging rate of more than 100 kW?

Someone earlier in the thread mentioned that some 70D models have 400V packs. I don't know if this is the case, but it would appear to make sense given that you're getting 116 kW.

If you have access to the CAN bus to read BMS frames, you should be able to tell from the pack voltages whether you have a 350V or 400V pack.

That would make sense, I just assumed it had a 350V pack.

I have no idea how to check the CAN bus, but I think the voltage should be printed on the battery sticker, I can check that if I don't forget.

@Max* could just look at the sticker on his battery and see if it says 350V or 400V.

I'll try to remember to do it tonight after I change out of my work clothes. It's under the car by the wheel axles, right?

Yes. Just look behind the front wheel on the passenger side. Some will say you have to turn the wheel but I'm able to see and photograph mine without turning the wheel. I bet that it says 70 kWh,400VDC at the top of the sticker.

I know for a fact it's not a 75kwh battery, I got mine 2+ years ago when they just killed off the 60 and released the 70s.

ETA, nevermind, I could've sworn you said 75kwh?, did you quick edit your post?

he he. Yep!

Quite true. However, with the number of battery pack revisions out there, I'd probably trust the CAN bus readings more than the sticker.

Actually, the original 70 kWh had a 350 V pack. The reason that it could charge at 116 kW is because it could draw much higher current than Tesla permits on the newer 75 kWh.

See the battery sticker in this thread:

Battery table

Also, in the charging video I posted above, it is also apparent that the vehicle has a 350 V pack.

Yeah, feel free to check under the car, but you have a 350 V pack...

Thank you. I knew that was the case from watching the stages of this in their history. They were selling the 60 and 85 sizes as their two voltage level battery packs. Then they rolled out the chemistry change with the extra silicon, which increased their capacity a little bit, which is when those two sizes both went up a little to 70 and 90, but those were still the 350V and 400V packs, respectively.

Very well, satisfied by all the answers, I am reassured that a charging rate of 100 kW is as good as it gets for our 75kWh 350VDC battery pack.

 

[ColdRauv]

I think the 70D 350 volt battery can charge at 115kW, not for long though. Also it is drawing more than 350 amps at the start of a charge.

 

[vystrcil]

Haven't even had mine a week, but the highest I've seen so for was in Italy, TX. 81kW-288 mi/hr

 

[Lanber]

No. The 70 pack is 350 volts. Look on video

Just to let you know -- the mi/hr number is the AVERAGE for the session, not an instantaneous reading of charge rate. The kW reading is the way to assess your current charging rate.

 

[cmaster]

It depends on the SoC and how warm or hot the battery is. When I'm driving 2 hours and get a SoC of 15%, I would get something in the 112kw - 116kw range.

 

[jelloslug]

I have seen 100kw/h in my S75D but nothing higher.

 

[Tummy]

I think this is the highest I've seen it. Does it mean that it's 112 kW instant, but average 99 kW?

Not with a 75kwh battery.

 

[cmaster]

I prove it to you this weekend.

The nominal voltage is not as high as the 85 or 100, but, you can get 112 kw briefly. Then afterwards, it gets around 96 kw.

I'd love to see it. You'd be the first person to ever show a charging rate that high on a 75.
