Regenerative braking in electric vehicles works on the principle of converting kinetic energy into electrical energy to charge the battery. How does it actually happen? Essentially, the motor is operated in reverse, and the kinetic energy is converted into electricity through electromagnetic induction. This way, the energy lost during deceleration is recovered, contributing to the range. What about efficiency? It typically ranges between 10-30%.

When it comes to running an electric motor in reverse, it does require some technical understanding, but if we think about it simply: a motor running in reverse essentially acts like a generator. In the projects I’ve worked on, we tested an electric vehicle for city driving and achieved regenerative braking efficiencies between 15-22%—the range gain is especially noticeable in stop-and-go traffic.
Practical tip: If you're driving an EV, besides using "eco mode," try not to slam the brake pedal. Gradually reducing speed recovers more kinetic energy. In fact, some newer models let you optimize regenerative braking levels with cruise control settings—worth comparing these features before buying.
