125kW on a 75D

[ucmndd]

Fastest I’ve seen so far on my 75 is 130kW now... but the taper is definitely more aggressive, and charging overall seems to usually take longer (especially if it is hot out?). This session actually dropped to 0kW before ramping back up to mid 60s for the duration of the charge. Actual ambient was about 85F despite the car reporting 103...

(And yes, I tried changing stalls... other one did the same thing/dropped to 0 after a few minutes and then ramped back up slowly... was super weird!)

How do you access that display showing all the power and temp specs?

Some disassembly required ;-)

Wow 130kw that's insane

don’t get too excited... this SC session was painfully slow in the end. I actually switched chargers twice before just letting the car do it’s thing. Seems the new firmware has some “tip in”...

Where can I see those data on the battery temperature?

Yes, would like to know as well.

Probably rooted.

If you have root or don’t mind pulling your dash apart and plugging and Ethernet cable into the IC, it is pretty easy on MCU1 to enable.

Reviewing the data, I think the poor charging performance was actually temperature related. It hit the 45c battery threshold, and couldn’t keep it cool enough with the available cooling resources. So it started ramping up from 0 until it found what it could sustain and stayed there.

Mind posting a how-to or a link to someplace that shows how to do said work?

So some searching. It's not for the faint of heart and you need some specialized cables and I've heard recent firmware closes the easiest root path.

I have seen up to 130kw speed on my 75D.
