Grüezi, we now have two beautiful wallboxes installed in the company. Both with enough conductor cross-section (4 mm2 wg. cable length) and protection, nevertheless our Mini SE (and also a brand new ID.3 S) charges only with 6.7 kW. We always use the type 2 cables that accompany the car. The wallboxes are Vestel EVC04-22, which are set inside to a maximum of 16A. Thus, according to my Casio pocket calculator, something about the 11 kW should be accessible. or do you have another wallbox and come up with more kW? Best regards
