A control unit (12) of the power storage group (10) performs authentication communication with a control unit (32) of the electric moving body by using a mode of current flowing through the power line in a state where the power storage group (10) is attached to the electric moving body (30). The control unit (12) of the power storage group (10) measures the contact resistance between the power storage group (10) and the electric moving body on the basis of the voltage of the power line on the power storage group (10) side, the voltage of the power line on the electric moving body side received from the control unit (32) of the electric moving body, and the current when authentication communication is performed using the mode of the current flowing through the power line.
蓄电组(10)的控制部(12)在蓄电组(10)被安装在电动移动体(30)的状态下,利用在电力线中流动的电流的模式与电动移动体的控制部(32)进行认证用通信。蓄电组(10)的控制部(12)基于电力线的蓄电组(10)侧的电压、从电动移动体的控制部(32)接收到的电力线的电动移动体侧的电压以及利用在电力线中流动的电流的模式进行认证用通信时的电流,来测定蓄电组(10)与电动移动体的接触电阻。
