Provided is a control method of a battery including a relay which can accurately estimate a temperature of a relay. The control method of the battery comprises the steps of: measuring an initial temperature of a shunt resistor connected on a charge/discharge path of a battery; measuring a current temperature of the shunt resistor; estimating a temperature of a relay using a difference between the current temperature and the initial temperature of the shunt resistor; and determining whether the estimated temperature of the relay exceeds a first temperature.
