How many kWh is the Lexus NX battery?
In the Lexus NX lineup, battery capacity depends on the variant. The plug-in hybrid NX 450h+ uses a battery pack of 18.1 kWh gross (roughly 14.5 kWh usable). Non-plug-in hybrids use a much smaller high‑voltage battery, around 1.0–1.5 kWh, depending on year and market.
The following breakdown covers the main variants in recent NX generations, with emphasis on the difference between PHEV and HEV models.
Battery sizes by NX variant
Note: The numbers refer to the battery pack capacity (in kilowatt-hours, kWh). Usable capacity and charging performance can vary by market, year, and option packages.
- NX 450h+ (plug-in hybrid): 18.1 kWh battery pack (gross). Usable capacity typically around 14.5 kWh. Electric range is generally about 37 miles (roughly 60 km) on EPA/market tests, depending on conditions.
- NX 350h / NX 250h (non-plug-in hybrids): Traction/drive battery around 1.0–1.5 kWh depending on year and market. These models rely on the internal combustion engine with hybrid assist rather than standalone electric driving.
Bottom line: If you’re after a plug-in option with meaningful electric-only driving, the NX 450h+ offers the larger 18.1 kWh pack. For traditional hybrids, the battery is a compact pack designed mainly for hybrid efficiency rather than extended EV range.
Summary
The Lexus NX battery varies significantly by variant: about 18.1 kWh gross (≈14.5 kWh usable) for the NX 450h+ plug-in hybrid, and roughly 1–1.5 kWh for the non-plug-in NX hybrids. Your exact figures can differ by market and model year, so consult the official specifications for your specific vehicle.
