What IS the battery capacity of Lexus 300E?
The Lexus UX 300e uses a 54.3 kWh battery pack with roughly 52 kWh of usable energy in everyday driving. The exact usable capacity can vary slightly by market and software calibration.
Battery capacity overview
Below are the key figures and what they mean for performance, charging, and everyday usability.
- Gross capacity: 54.3 kWh (total pack rating)
- Usable capacity: about 52.0 kWh (net energy available to the drivetrain)
- Battery type: Lithium‑ion chemistry used by Lexus (typical power pack configuration for the model)
- DC fast charging: up to 50 kW (CCS) for rapid replenishment
In practice, usable capacity determines how far you can drive on a full charge and how quickly you can restore energy, while the gross rating reflects the overall energy stored in the pack.
How it's measured in the UX 300e
Automakers distinguish gross (total pack) capacity from usable (net) capacity. The UX 300e uses a lithium‑ion pack with a gross rating of 54.3 kWh and a usable portion around 52 kWh, which is what the vehicle’s range and charging performance are based on. This distinction helps explain why on-paper energy capacity and real-world range can diverge.
Regional specs and charging details
Across markets, the pack is the same, but charging specifications and official range figures are reported using different testing standards. The following notes summarize what you’ll typically see for the UX 300e.
- Gross capacity: 54.3 kWh (battery pack rating)
- Usable capacity: around 52.0 kWh (net usable energy)
- On-board charging: commonly 6.6 kW AC (standard in many markets; some regions offer higher)
- DC fast charging: up to 50 kW (CCS) for quicker recharging
Real-world range varies with temperature, driving style, road conditions, and battery health. Published range figures use different test cycles such as WLTP in Europe and EPA in the United States, which can yield different numbers even for the same battery pack.
Summary
The Lexus UX 300e couples a 54.3 kWh battery pack with about 52 kWh of usable energy, balancing everyday practicality with modern fast-charging capability. While the exact range depends on market-specific testing cycles and conditions, the pack design prioritizes efficient urban and suburban EV commuting alongside reasonable charging speed.
