New OTA Update Improves F-150 Lightning DC Fast Charging Times

[PJnc284]

Just rewatched the 10% challenge from Out Of Spec last and looks like they were getting around 500 amps during the boost way back last April. Didn't show the entire charge but it peaked at 176kW v Tom's 182kW and finished with 39% (40.3kWh) after 15min v Tom's 42% (42.3kWh). 450 amps should've been in the 160's. Seems something was afoot way back and went mostly unnoticed besides the charging speed bragging threads.

Below voltages are based on Tom's video with theoretical max boost at 450 and 500 amps.

Battery %	Voltage	450 a	500 a

15%	356	160.2	178
20%	362	162.9	181
25%	364	163.8	182
30%	365	164.25	182.5
35%	367	165.15	183.5
40%	370	166.5	185
45%	370	166.5	185
50%	372	167.4	186

Then again Branden Flasch did a 10% challenge back in Octoberish and managed to get up to 40% (~37kWh delivered) with 450 amps and maxing out at 162kW

Well for giggles I went to give it a try but think I got a goofy stall. No preconditioning since google seemed to think the station wasn't compatible but it was fairly mild today so shouldn't matter much. Looks like I was getting 500 amps (peak of 180kW) for about 5 min before the station decided to derate me and dropped to 420 amps (~150kW) for a couple minutes. Did pick back up to 180kW for about 1min before the truck dropped the requested amperage to < 400. Went from 14-43% in 15min with the Supercharger billing for 38.149kW. Battery temps started at 64 and was 86F by the time it finished.

So my brother who has the truck sent me a pic of him charging at 336 amps the other day. I told him he was full of it, but it looks like its real.

One of my work colleagues diched his Rivian for a Lightning. All good signs.

Nice to see.
