The recent update 2021.12.25.7 has an update which allows the Universal Mobile Charger (UMC) Gen 2 charger to now charge at full rated power.
Previously the 10amp and 15amp tails only actually allowed / limited to 8amp and 12amp speeds respectively. It’s now gone up to 10amps and 15amps respectively.
Great news especially for those who only use the UMC at home. The pictures show before and after the update using the same socket and charger setup. Current was 12A and is now 15A.
Note the power says 3kw in both pics because it’s rounded.
Also note that I didn’t get the higher rate straight after the update. apparently you needed to plug in the UMC for the car to communicate with the UMC to update its firmware. We got it this morning after plugging in overnight.
