What'snew automotive design

摘要

Mazda has developed a passenger vehicle regenerative braking system that uses a capacitor. The i-ELOOP features a 12-25V variable voltage alternator, a low-resistance electric double-layer capacitor (EDLC) and a DC/DC converter. The system starts to recover kinetic energy the moment the driver lifts off the accelerator pedal and the car begins to decelerate. The variable voltage alternator generates electricity at up to 25V before sending it to the EDLC for storage. In real-world driving conditions with frequent acceleration and braking, the system improves fuel economy by about 10 per cent. The i-ELOOP will begin to appear in Mazda's vehicles in 2012.
