RZ 450e
Premium
Lexus' first dedicated EV. Only 6.6kW onboard charger (28A) — a 32A charger is sufficient.. Before you spend $2,000–$8,000 on a panel upgrade you may not need, get a real NEC 220.82 load calculation from an IBEW Master Electrician.
Sharing this link prefills the calculator with your Lexus RZ 450e.
