Abstract

An energy storage system for a vehicle is provided. The system includes a plurality of energy storage devices that are arranged to provide output power to a vehicle and are connected in parallel with each other. A plurality of sub-relays are connected to the plurality of energy storage devices, respectively. A controller then measures the degrees of deterioration of the respective energy storage devices and selectively opens or closes the sub-relays based on the amount of output power required for a vehicle and the measured degrees of deterioration such that a sub-relay connected to an energy storage device having a low degree of deterioration is closed first.
