Mazda to introduce unique regenerative braking system

Mazda Motor Corporation announced that beginning 2012, its passenger cars will have a regenerative braking system that is capable of improving fuel economy by approximately 10%. Called the i-ELOOP system, it uses a capacitor and is considered the first of its kind in the world. i-ELOOP is short for “Intelligent Energy Loop,” which Mazda says represents the company’s intent to recycle energy in an intelligent way. The new system converts the kinetic energy of the vehicle into electricity as it decelerates. It then uses the electricity to power several systems such as climate control and the audio system, as well as other electrical components. The i-ELOOP uses a unique capacitor technology that stores large volumes of electricity. But unlike batteries, it can be quickly charged and discharged and is resistant to the deterioration that usually results after prolonged use. Mazda’s new system does not need a dedicated electric motor and battery, unlike the regenerative braking systems found in hybrid vehicles. (December 2, 2011)
