What is the maximum charge rate for the Lexus RZ 450e?
The maximum charging rate for the Lexus RZ 450e is 150 kW when using DC fast charging. For home or slower charging, the on-board charger supports about 6.6 kW as standard, with an 11 kW option available in some markets.
In more detail, the RZ 450e carries a roughly 71.4 kWh gross battery with usable capacity in the ballpark of 64 kWh, and it uses CCS2 for DC fast charging. The 150 kW peak DC rate can deliver faster replenishment on compatible chargers, while AC charging is slower and depends on market specifications and whether the 11 kW option is equipped. Real-world charging performance will vary with battery temperature, current state of charge, and charger capabilities.
Charging capabilities
Below are the key charging specifications that affect how quickly the RZ 450e can recharge in different scenarios.
Direct-current (DC) fast charging
- Peak DC fast charging rate: up to 150 kW using CCS2 connectors
- Battery capacity: approximately 71.4 kWh gross, around 64 kWh usable
- Typical 0–80% charging time: roughly 20–30 minutes under optimal conditions on a high-power charger
- Connector type: CCS2 for DC fast charging
DC fast charging is designed for short breaks during longer trips, with the highest speed available when the battery is at a moderate temperature and state of charge.
Alternating-current (AC) on-board charging
- On-board AC charger: 6.6 kW standard, with an 11 kW option in some markets
- Home charging implications: about 9–10 hours on a 6.6 kW charger; roughly 5–6 hours with an 11 kW setup
- AC plug type: commonly 240V (or regional equivalents) with the appropriate on-board charger
AC charging is intended for overnight charging or daily topping up, offering convenient, gradual replenishment between trips.
Practical considerations
In real-world use, charging speed is influenced by battery temperature, charging station capability, and current battery state of charge. The RZ 450e’s 150 kW DC limit means faster replenishment on capable stations, while everyday charging at home will typically occur at 6.6 kW unless the higher 11 kW option is installed.
Summary
The Lexus RZ 450e supports a maximum DC fast charging rate of 150 kW (CCS2), enabling rapid recharges on compatible networks. For home or slower charging, it delivers about 6.6 kW as standard, with an 11 kW option in some markets, translating to roughly 9–10 hours to full on 6.6 kW or about 5–6 hours on 11 kW. Battery capacity is about 71.4 kWh gross with roughly 64 kWh usable, and real-world speeds vary by conditions and equipment.
