Continuing the discussion from Status of SP140?:
@jhair brought up a good point about charging. That is, 2 hours charging time for a regular 15a 120v outlet (in the USA) can only provide 12a continuously - 1.4kWh. So 4kWh/1.4kW = 2.85h. And that’s ignoring charger efficiency losses.
And batteries also need to slow down rate of charge near the end, correct?
I’m just curious what the sp140 fast charger will look like - if it will need to be hooked up to a 240v outlet to fast charge for the 2 hour charge time. Which if so is totally reasonable as it’s a tremendously large battery pack.
