Excellent guide on iX charging


The BMW wallbox ranking is very likely the identical as other industrial wallboxes – the challenge is the variety of circuit on which you would put in it. In the US at the very least, electrical code demands that the circuit breaker should really only provide 20% of the highest load of the breaker. And most residence wiring supports a single circuit most 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 supply is 40 amps. Some wallboxes on the other hand help 48 amps, but only if tough-wired into your electrical panel (which can be done) – ChargePoint, Wallbox (the charger) and Juicebox units are all able of delivering 48 amps (if hard wired), and probable so is the BMW wallbox though any data out there is sketchy – that’s why the 48 amps claim most likely.

You CAN install 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 incredibly uncommon), but that necessitates rewiring circuits and appreciably a lot more expenditure, and genuinely not much reward. Most house charging will take place overnight anyway, and you are unlikely to operate your EV down to zero every day so normal charging time with a 40 amp delivery will be 6-8 hrs -cutting that down to 4-6 hrs is not that a lot acquire with typical charging use circumstance, for a great deal far more problems and price, and surely not Supercharger territory.

An electrician would be a fantastic idea for any of those situations, but if any person was contemplating Do it yourself with out the needed pre-wiring, you could theoretically just put in a 60 amp breaker and outlet, buy a NEMA 14-60 plug, established their charging device to 48 amps, and VoilĂ ! 48 amps to your auto – violating code with the danger of overloading your circuits and burning your house down. So hard-wiring to your panel seems like a better route if you truly needed or essential 48 amps – a lot more highly-priced than a plug-in but a discount in the prolonged operate, with some tiny negatives (charging device not conveniently swappable for example).
