22kW Question

[yessuz]

just to be details nazi:

you cannot charge battery with AC, because batteries have a single polarity.

Batteries are charged with DC only. Therefore your AC - DC conversion happens in the car. Therefore the "charger", per se, is in the car only.

AC thing on the wall is just a power source, and "charger cable" is just extension lead. well if to be precise

Podpoint call it a charger.

I'll have a chat with the electrician in a couple of weeks, see if a 50kW DC Charger is possible at home, see what he says

What I am saying is that you cannot charge ANY battery with AC. It is just impossible. Therefore all electric cars have internal AC - DC converter.

Hence, technically, you cannot call it a charger. Charging station, charging unit, but not a charger.
All AC units are much much closer to an extension lead than to a charger

But... Why?

 

[Mr H]

There are at least two reasons:

• Providing 11kW 3 phase and 7kW 2 phase can be done with just three 3.5kW on board chargers, configured with one per each phase for 11kW or with 2 to a single phase, for 7kW. So just a 50% overhead for 3 phase.
• Many countries provide a low current 3 phase supply to domestic properties, so there is a need for a low current 3 phase option in those areas. However, most couldn't cope with 3 x 32A.

The ZOE supports 22kW charging by using the motor coils as part of the charging circuit.

Our ZOE takes 43kw AC thanks to the chameleon charger
