What is the battery capacity of Lexus NX 350h hybrid?
The Lexus NX 350h’s self-charging hybrid system relies on a compact high-voltage battery with about 1.6 kWh of capacity. This non-plug-in setup aims to balance efficiency and seamless operation rather than long electric-only range.
In the NX 350h, the battery works with a 2.5-liter gasoline engine and dual electric motors to provide smooth power, stop-start functionality, and regenerative braking. The pack is designed to deliver dependable performance without requiring external charging.
Battery fundamentals in the NX 350h
Key facts about the NX 350h battery are listed below.
- Battery type: Nickel-metal hydride (NiMH) high-voltage pack used by Lexus’ hybrid system
- Capacity: typically cited as around 1.6 kWh (nominal) for the NX 350h
- Role: powers the electric motor to assist the gasoline engine and enable limited electric driving at low speeds, while recharging through regenerative braking
Because the NX 350h is a non-plug-in hybrid, the battery is charged by the engine and braking rather than by plugging in.
Context and comparison
For buyers seeking a larger electric-only range, Lexus offers the NX 450h+ plug-in hybrid variant with a much larger battery (about 18 kWh). The NX 350h’s smaller pack is designed for daily efficiency rather than extended EV-only miles.
Quick comparison
The NX 350h's battery is small enough to fit under the floor and to provide seamless assistance without requiring plug-in charging; the plug-in NX 450h+ is the alternative for those who want substantial electric driving.
Summary: The NX 350h employs a compact NiMH battery with roughly 1.6 kWh capacity, supporting the hybrid system's electric assist and regenerative braking. If a larger electric range is desired, consider the NX 450h+ plug-in hybrid.
How much does it cost to replace the battery in a Lexus NX hybrid?
