The control unit (12) of the power storage group (10) communicates with the control unit (32) of the electric moving body in a state in which the power storage group (10) is attached to the electric moving body (30). The communication wiring (Lc1) connects a node of the power line (Lp1) closer to the power supply terminal (Tp) than the first switch (RYp) and a control unit (12) of the power storage group (10). The overvoltage protection circuit (19) turns off a second switch (SWc) inserted into the communication wiring (Lc1) when an overvoltage of the power line (Lp1) is detected during communication between the control unit (12) of the power storage group (10) and the control unit (32) of the electric moving body.
蓄电组(10)的控制部(12)在蓄电组(10)被安装在电动移动体(30)的状态下与电动移动体的控制部(32)进行通信。通信用布线(Lc1)将电力线(Lp1)的比第一开关(RYp)靠电源端子(Tp)侧的节点与蓄电组(10)的控制部(12)之间进行连接。过电压保护电路(19)在蓄电组(10)的控制部(12)与电动移动体的控制部(32)之间的通信过程中当检测到电力线(Lp1)的过电压时,将被插入到通信用布线(Lc1)的第二开关(SWc)关断。
