What is the deal with the choice of buying a single vs. dual charger? It seems that the single charger handles 40 amps, and the dual 80 amps of 220 v AC. But why is this? Why is there any dedicated charger at all? Why isn't the PEM simply run in reverse to charge the battery, exactly the same way that it is done during regenerative breaking?
