Excellent guide on iX charging

The BMW wallbox rating is likely the identical as other professional wallboxes – the problem is the variety of circuit on which you would put in it. In the US at the very least, electrical code needs that the circuit breaker need to only provide 20% of the maximum load of the breaker. And most residence wiring supports a single circuit utmost of 50 amps – if you use a plug-in wallbox with a 14-50 plug on a 50 amp circuit breaker, the maximum it can provide is 40 amps. Some wallboxes having said that assistance 48 amps, but only if difficult-wired into your electrical panel (which can be done) – ChargePoint, Wallbox (the charger) and Juicebox units are all able of offering 48 amps (if tricky wired), and likely so is the BMW wallbox whilst any facts accessible is sketchy – for this reason the 48 amps declare likely.

You CAN set up a 60 amp breaker and use a NEMA 14-60 plug with a 48 amp rated wallbox for a plug-in setup (which would be quite strange), but that requires rewiring circuits and noticeably a lot more expenditure, and actually not a lot benefit. Most property charging will come about right away in any case, and you are unlikely to run your EV down to zero every day so common charging time with a 40 amp shipping and delivery will be 6-8 hours -slicing that down to 4-6 hrs is not that a great deal get with normal charging use situation, for a large amount far more problems and expenditure, and certainly not Supercharger territory.

An electrician would be a excellent idea for any of people situations, but if any one was imagining Diy with out the needed pre-wiring, you could theoretically just install 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 hazard of overloading your circuits and burning your property down. So difficult-wiring to your panel sounds like a better route if you seriously desired or essential 48 amps – much more highly-priced than a plug-in but a bargain in the lengthy operate, with some little cons (charging device not quickly swappable for illustration).
