regenerative braking: meaning, definition, pronunciation and examples
LowTechnical
Quick answer
What does “regenerative braking” mean?
A braking system in electric or hybrid vehicles where the electric motor runs in reverse to slow the vehicle, converting its kinetic energy back into electrical energy to recharge the battery.

Meaning and Definition
A braking system in electric or hybrid vehicles where the electric motor runs in reverse to slow the vehicle, converting its kinetic energy back into electrical energy to recharge the battery.
More broadly, any energy recovery mechanism that slows an object by converting its motion into another form of energy (often electrical) for storage and reuse, thereby improving efficiency.

FAQ
Frequently Asked Questions
No. It works alongside traditional friction brakes. At very low speeds or during hard braking, friction brakes are still required.
Yes. When activated, it creates a noticeable slowing or dragging sensation as soon as you lift off the accelerator, often described as 'engine braking' but smoother.
Primarily, yes. It is a defining feature of Battery Electric Vehicles (BEVs) and Hybrid Electric Vehicles (HEVs). Some trains and racing cars (using KERS) also use the principle.
Yes. Battery efficiency is lower in cold weather, which can limit the amount of charge the battery can accept, thereby reducing the effectiveness or availability of regenerative braking.
A braking system in electric or hybrid vehicles where the electric motor runs in reverse to slow the vehicle, converting its kinetic energy back into electrical energy to recharge the battery.
