Energy storage system

Abstract

An energy storage system includes a plurality of battery units; a plurality of thermistors detecting a temperature of the plurality of battery units; a multiplexer performing multiplexing on the plurality of thermistors, and connecting a thermistor selected from among the plurality of thermistors to a reference resistor; a power switch unit arranged between the reference resistor and a power voltage terminal; and a control signal input unit receiving a control signal applied to the multiplexer and the power switch unit, and receiving two or more control bits contained in the control signal. In the energy storage system, a temperature measurement operation is performed at a plurality of measurement positions, whereby a current state of a battery may be accurately detected, an entire circuit may be reduced and simplified, and low power consumption may be realized.
