The Zoe has a kind of unique internal charger. The I-MiEV and most EV's have a inverter to convert DC to three Phase AC to drive the propulsion motor. They also have a battery charger to convert single phase AC to DC to charge the battery pack. However, an inverter can be made to be bi-directional, that is AC in gives DC out or DC in gives AC out. The old Aeroviroment inverters (the people that brought you the "Impact" prototype GM-EV1, EVSE's and all kinds of neat military stuff) worked this way. It's a natural way to do it. It eliminates the weight, cost and space for the onboard charger. This is the type of system that is used in the Zoe. The problem for us, not the rest of the world, is that most electric service in this country is single phase which would prevent it's use except where three phase power could be found. The other neat thing is that everything is "onboard" in the vehicle---no expensive high voltage DC charger or connecters for QC--- its all done with AC. Heck, if we can make Bruce Jenner AC-DC and DC-AC it should be easy with an EV :lol: !

[QUOTE="siai47, post: 29482, member: 1483"] The Zoe has a kind of unique internal charger. The I-MiEV and most EV's have a inverter to convert DC to three Phase AC to drive the propulsion motor. They also have a battery charger to convert single phase AC to DC to charge the battery pack. However, an inverter can be made to be bi-directional, that is AC in gives DC out or DC in gives AC out.
