I have a 1x35A main connection.*
Our advice: 1-phase 32A charging station with 7.4kW power. To prevent a power outage, a limit can be set. This can be controlled dynamically (take extra costs into account if you want to use Dynamic Load balancing) or static. If the BMW i3 is being charged at full power, the battery will be full within 4.5 hours. If the charge capacity is limited (Static Load Balancing) at 20A, the battery will be fully charged within 7 hours.
