Weight and performance impact:
- Battery weight varies: Most EV batteries weigh between 200 and 600 kg (440–1,300 lbs), depending on capacity and design.
- Heavier battery = more range, but also more mass: Larger capacity improves range, but adds weight that can affect handling and efficiency.
- Acceleration and braking: Extra mass can slightly reduce acceleration and increase braking distances, though many EVs compensate with powerful motors and regenerative braking.
- Low center of gravity: The battery is usually mounted low in the chassis, which helps improve stability and cornering.
In short, battery weight is a trade-off between range and performance — smart engineering minimizes downsides while maximizing benefits.
