i-ELOOP

The i-ELOOP regenerative braking system represents Step Two of Mazda’s technology development vision, the Building Block Strategy. The moment the driver lifts off the accelerator pedal a variable voltage alternator begins generating electricity at up to 25V before storing it in an Electric Double Layer Capacitor (ELDC). This electricity is used to power the vehicle’s electrical systems, such as the air conditioner, at times when he accelerator is depressed or when i-stop is functioning. As long as there is sufficient charge stored in the capacitor and battery, the system removes the need for the engine and alternator to generate electricity. As a result, engine power is increased by around 10% and fuel economy is enhanced.
