From a standard wall outlet to a 48-amp wall unit — see exactly what each setup delivers for your BMW, and which one your daily driving actually needs.
Installation reality check: a 240V circuit typically requires an electrician ($300–$1,500 depending on panel distance and capacity). 48A hardwired units need a 60A breaker. Many utilities offer EV time-of-use rates and charger rebates — check yours before buying hardware.
Charge times assume ~90% AC charging efficiency and are capped by each car's onboard charger. Overnight window assumed 10 hours. Costs use your electricity rate against the battery's usable capacity. Always size circuits with a licensed electrician.
