EVs do not need special brake pads

By · Published by Everything Blog

In short

Electric models leverage regenerative systems to capture kinetic energy and deliver up to 0.5g of deceleration force. Standard mechanical friction setups remain necessary to bridge the gap by offering up to 1.1g of braking power when batteries are full or during sudden stops. While some marketed pads feature galvanized backing plates to resist corrosion from infrequent usage, these additions offer no improvement to pedal feel or stopping effectiveness.

EVs do not need special brake pads

Amrit Mirchandani Changaroth

Are electric vehicle brake pads any different from those of engine-powered cars?

Electric vehicles (EVs) generally do not require special brake pad or disc material. However, this has not stopped manufacturers from marketing special compositions for their equipment.

EVs slow down by regenerative braking, the use of traditional mechanical friction brakes or a mixture of both.

Although regenerative braking is sufficient for the average commute, there are several scenarios where the friction brakes are necessary, like when the EV is fully charged and cannot activate regenerative braking.

Regenerative braking produces a deceleration force of up to 0.5 G-force (g). This is when the EV’s motor is used as a generator to capture kinetic energy to feed the battery while slowing down the car.

Traditional road car brakes may produce up to 1.1g of deceleration. To bridge this gap from regenerative braking, mechanical friction brakes are still needed. In fact, at lower speeds, friction braking is often used to slow down the car, rather than regenerative braking.
