Excellent guide on iX charging

The BMW wallbox score is possible the similar as other commercial wallboxes – the concern is the form of circuit on which you would install it. In the US at the very least, electrical code calls for that the circuit breaker ought to only produce 20% of the most load of the breaker. And most dwelling wiring supports a one circuit greatest of 50 amps – if you use a plug-in wallbox with a 14-50 plug on a 50 amp circuit breaker, the most it can deliver is 40 amps. Some wallboxes even so guidance 48 amps, but only if hard-wired into your electrical panel (which can be accomplished) – ChargePoint, Wallbox (the charger) and Juicebox models are all able of providing 48 amps (if hard wired), and probably so is the BMW wallbox though any details available is sketchy – hence the 48 amps assert almost certainly.

You CAN put in a 60 amp breaker and use a NEMA 14-60 plug with a 48 amp rated wallbox for a plug-in set up (which would be very uncommon), but that needs rewiring circuits and drastically more price, and truly not much profit. Most property charging will occur right away in any case, and you are not likely to operate your EV down to zero everyday so common charging time with a 40 amp delivery will be 6-8 several hours -chopping that down to 4-6 hours is not that considerably attain with regular charging use case, for a large amount a lot more trouble and expenditure, and undoubtedly not Supercharger territory.

An electrician would be a good strategy for any of those scenarios, but if everyone was pondering Do it yourself devoid of the required pre-wiring, you could theoretically just put in a 60 amp breaker and outlet, get a NEMA 14-60 plug, set their charging unit to 48 amps, and Voilà! 48 amps to your car – violating code with the threat of overloading your circuits and burning your residence down. So hard-wiring to your panel seems like a much better route if you really wanted or needed 48 amps – more highly-priced than a plug-in but a discount in the lengthy run, with some small shortcomings (charging device not quickly swappable for instance).
