In reply to Gino.

You can’t. It’s just that table. AFAIK it’s like that in the specs. Cars might “step” between the currents or adjust in a linear fashion, but I am fairly sire these are “the” values and that’s it.

Hi how can you calculate these figures

Just to emphasize: the currents we are talking about are “true” currents. Cables don’t care if the current is phase shifted with the voltage. Since ZOE (at least the Q version) draws roughly 6 amps reactive current because of filter capacitors (see https://canze.fisch.lu/charging-currents-single-phase/ ) , especially at low currents, the actual power uptake is lower than the expected amps times 230 volts.

In reply to Borut. Nice hack! :-)

I install a small button on the charger’s side of the type2 cable for changing a resistor value between 220E and 680E.
Now I can select between 21.6kW and 9.3 kW charging power at 22 kW charger. The 1500E resistor didn’t work.

Either one should do. If you put it car side, the car will throttle. If you put it charger side, the charger should not set it’s PMW signal above said current, and the car should adhere to that too. Cool mod.

I will put additional resistor of 460 Ohm with switch in serial with existing one, in to charging cable for manual selection of cable type. Must I put it on the car’s side or on the charger port’s side for maximal power selection (32 or 20 A)?
