Then, when the master cannot communicate with the host due to some abnormality, the host can send a command to the slave which can normally communicate with the host to be the master. When there is a communication request (interrupt request) from the host during communication between the master and slave, the master immediately interrupts communication with the slave and communicates with the host. After the communication with the host is completed, the master retransmits the interrupted transmission data to the slave and requests the retransmission of the interrupted reception data.

御に移行する。When a certain battery pack cannot be charged / discharged for some reason, the master sends information of a request for replacing the battery pack to the host. As a result, the host informs and outputs the battery pack that has received the replacement request via the output device such as the display device or the printing device. For a battery pack that cannot be charged or discharged due to some failure, stop charging and discharging only the battery pack group connected in series including the battery pack, and charge the battery pack group in that row at the time of recovery from the failure or replacement. Discharge is possible. At that time, charging / discharging is started only when the total voltage difference between the battery pack groups in the other columns is within a certain voltage range. In the column that started charging / discharging, a current flows due to the voltage difference from the battery packs in the other columns.When this current is large, the charging / discharging period is shortened, and as the flowing current decreases, the charging / discharging period becomes longer. If the current is made longer and the flowing current becomes 0, the normal charge / discharge control is started.

It is determined whether there is a cell having a voltage of 1 or more (step S13). If there is a cell having a voltage equal to or higher than the set value V1, the communication interval with the battery pack including the cell is shortened (step S14).
