The intensity of regenerative braking can be adjusted based on the driver’s preference using different driving modes, which we will discuss in the next section.


Regenerative Braking Modes in the Chevrolet Bolt EV

One-pedal driving mode

One of the standout features of regenerative braking in the Chevrolet Bolt EV is the one-pedal driving mode. In this mode, the regenerative braking system is enhanced to such an extent that it allows the driver to control the vehicle’s speed using just the accelerator pedal. By simply releasing the pedal, the vehicle slows down significantly, almost to a complete stop, without needing to use the traditional brake pedal.

This mode not only maximizes energy recapture but also provides a unique and engaging driving experience. It allows drivers to navigate through city traffic with ease, minimizing the need for constant braking and accelerating.

Standard braking mode

In the standard braking mode, the regenerative braking system in the Bolt EV operates similarly to a traditional vehicle’s braking system. When the brake pedal is applied, hydraulic brakes are engaged, providing additional stopping power alongside the regenerative braking. This braking mode offers drivers a more familiar feel compared to traditional vehicles and is useful in situations that require quick and abrupt stops.

Regen-on-demand mode

The regen-on-demand mode in the Chevrolet Bolt EV allows the driver to manually control the intensity of regenerative braking using a paddle on the steering wheel. By pulling the paddle, the driver can increase the regenerative braking force, effectively slowing down the vehicle without using the brake pedal. Release the paddle, and the vehicle will resume coasting or accelerating, depending on the accelerator input.

This mode gives the driver greater control over the vehicle’s deceleration and further enhances energy recapture capabilities.

Efficiency and Range Improvement through Regenerative Braking

Increased overall efficiency

Regenerative braking significantly improves the overall efficiency of the Chevrolet Bolt EV. By recapturing and storing energy that would have otherwise been lost as heat through friction braking, regenerative braking reduces the reliance on the vehicle’s battery for power. This, in turn, leads to improved energy efficiency and increased driving range.

By utilizing regenerative braking, the Bolt EV can minimize energy wastage and maximize the use of available electrical energy.

Extended electric range

One of the key benefits of regenerative braking in the Chevrolet Bolt EV is its positive impact on the vehicle’s electric range. By recapturing and storing energy during deceleration, regenerative braking effectively adds extra mileage to the Bolt EV’s range. The more frequently regenerative braking is used, the more energy is recaptured, resulting in increased range.
