Lexus RZ Charging Time
A 2026 Lexus RZ takes about 8 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test. On a standard 120-volt outlet it takes about 56 hours. A full charge puts about 80.1 kWh through the plug for 257 miles of range.
Lexus RZ charging time by charger
Figures for the 2026 RZ 450e AWD (20 inch wheels - 235/50R20). 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 33 hr 23 min | 2.3 days |
| Level 2, 240 V, 16 A | 3.8 kW | 12 hr 31 min | 20 hr 52 min |
| Level 2, 240 V, 24 A | 5.8 kW | 8 hr 21 min | 13 hr 54 min |
| Level 2, 240 V, 32 A | 7.7 kW | 6 hr 15 min | 10 hr 26 min |
| Level 2, 240 V, 40 A | 9.6 kW | 5 hr | 8 hr 21 min |
| Level 2, 240 V, 48 A | 11.5 kW | 4 hr 10 min* | 6 hr 57 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 10 kW; if that is its limit, a faster wall charger won't shorten the 8-hour full charge.

Cost to charge a Lexus RZ
A full charge from empty draws about 80.1 kWh from the wall. At 18 cents per kWh it costs about $14.42, and a 20% to 80% top-up about $8.65. The EPA rates the RZ 450e AWD (20 inch wheels - 235/50R20) at 31.2 kWh per 100 miles, which works out to 5.6 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Lexus RZ fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Lexus's quoted figure for the RZ. The EV charging curve guide explains why it slows.
