8.25.1.2. Regenerative brake system

The primary purpose of regenerative brake system is to provide some power to help recharge the Li-ion battery and extend driving range. A secondary benefit is “engine braking” that operates based on battery conditions.

In the D (Drive) position, when the accelerator is released, the regenerative brake system provides some deceleration and generates power for the Li-ion battery. Power is also generated when the brake pedal is applied.

However, during high-speed driving you may feel that regenerative brake provides less deceleration than the engine braking in an ordinary vehicle.

This is normal.

Less deceleration is provided by the regenerative brake system when the Li-ion battery is fully charged. Regenerative brake is automatically reduced when the Li-ion battery is fully charged to prevent the Li-ion battery from becoming overcharged.

Regenerative brake is also automatically reduced when the battery temperature is high/low to prevent Li-ion battery damage.

The brake pedal should be used to slow or stop the vehicle depending on traffic or road conditions. The vehicle brakes are not affected by regenerative brake system operation.

The amount of regenerated charge varies depending on the drive mode and e-Pedal usage.
