I'm considering getting a 2019 Leaf 40kwh. As I primarily charge my current car, 530e, overnight from a normal outlet (220-16A) I would like to know if it is possible to control the power of the charger so that I stay well below the 16A and don't stress the installations?
In the BMW I can set charging power to fast-reduced-slow which controls the load on the outlet.
Don't rely upon in-car settings to protect your house wiring. Make sure you have an EVSE that is set so that the car can not possibly exceed the allowable current. The J1772 standard ensures the car will never demand more current than the EVSE is set to provide.
Not sure about your electrical codes, but in the US any continuous load must not exceed 80% of the circuit's rating, for safety. So if following that guideline you would need the EVSE to limit current to 12A. Also here, we stipulate only one device on a 240V circuit, while I believe all of your "normal" circuits are the higher voltage? So if this is a multi-outlet circuit, take care to remove any other substantial loads from it. A dedicated circuit would be safest.
I advise people who are unsure of electrical requirements to consult an electrician to make sure you're setting up safely and within any applicable electrical codes.
