i-ELOOP is a regenerative braking system. When you depress the brake pedal or use 

engine braking, the kinetic energy that occurs is converted to electrical energy by the power 

generator and the converted electrical energy is stored in the rechargeable battery (capacitor 

and battery). The stored electricity is used as power to charge the battery and the vehicle's 

electrical devices.



 A variable voltage alternator is incorporated in the power generator which converts 

the kinetic energy to electricity and can generate electricity efficiently according to the 

vehicle conditions.



 A capacitor is used to store large amounts of electricity instantly which can be utilized 

quickly.



 A DC-DC converter is incorporated which steps down the stored electricity to voltage 

useable by the vehicle's electrical devices.
