AC charging at max speed is perfectly fine and will not damage your battery in the slightest. DC Charging has speeds that dump so much energy, it creates heat, which damages batteries. You could charge new GM EVs, AC at around 19.2kW just fine.

I had a ‘20 Tesla Model 3 Performance and charged at max speed ~11.5kW from my Gen 3 Tesla wall charger (42mi/hr). And it wouldn’t warm the battery up at all.

Honestly, charging to 85% every day rather than the "Daily" limit of 70% is likely to do more harm than slowing the AC charging rate.

do you know if the mobile charger plugged into a 240V 14-15 connection but using a 60A breaker and larger cable would allow to charge at 48A? or the mobile units not as capable as the hard wired units? Getting our R1s next week.

I don't think 8, 9 or 10 kwh is going to make any difference on battery wear when they are rated to accept 200kwh. At 85% it's just going to stop.

This makes perfect sense. Level 2 charger, correct? Is there any literature promoting the adjustments you made - to increase efficiency?

[RelaxingRivian]

Can the mobile charger hit 40amps? Or max at 32?

[SuprimUpadhyay]

At 48 amps it should be giving more than 30-35mph right ? Or am I missing something ?

[ChadMoran]

Efficiency scales better with more amps, doesn't it? There's a fixed cost for conversion so the more amps you push the more that amortizes. Also, the wear on the battery is minimal. When you're DCFC it hits 10kW near the top of the pack.
