Secondary Battery System

Abstract

Provided is a secondary battery system includes: a secondary battery; a temperature control device for cooling the secondary battery; a battery management unit; and a temperature detector for detecting a temperature of the secondary battery, in which the battery management unit includes an SOC calculating part for calculating a state of charge (an SOC) of the secondary battery and a potential estimating part for estimating potentials of the anode and the cathode of the secondary battery, and in which the temperature control device is operated when an operating condition is set corresponding to the potentials of the anode and the cathode is met. Thus, it is made achievable to satisfy an elongated serve life of the battery and a cost reduction of a temperature control operation at the same time.

Dependencies are inferred from the claim text.
