Lexus RZ 450e charging time by charger power

How long the Lexus RZ 450e takes to charge at different charger power levels, capped by its own onboard limits.

Home wallbox7 kW0% → 100%10 hours 12 minutes
Public AC11 kW0% → 100%6 hours 29 minutes

AC rows assume constant charging power and a 0% to 100% charge. Real times vary with the onboard charger, temperature, and the charger you use.

The DC fast row (10% to 80%) is anchored to a measured charging time for this model, so it reflects the real charging curve. Times still vary with temperature and conditions.

Charging speed

Based on measured data, the Lexus RZ 450e charges 10% → 80% on DC fast charging in about 33 minutes, peaking at around 147 kW. Shares e-TNGA GEN1 pack/curve with bZ4X.

The Lexus RZ 450e is estimated to charge from 20% to 80% on public DC fast charging in about 29 minutes (ultra-fast DC).

Battery care

This car uses an NMC battery. For daily use, charging to about 80% and topping up to 100% only before long trips helps it last longer; heat is the main thing that ages it.

Savings vs a petrol car

This charge adds about 224 km of range for $32.99. Driving the same distance on petrol would cost:

Engine sizePetrol costYou save
≤ 1000 cc$42.70$9.72
1000–1500 cc$50.47$17.48
1500–2000 cc$62.11$29.13
2000–2500 cc$73.76$40.77
> 2500 cc$89.29$56.30

Estimated from typical combined fuel use by engine size and RON95 at $3.46/L. Charging at home saves the most; actual figures vary with driving and conditions.
