Abstract:
An object of the invention is to improve communication quality in a power storage management system.The above-mentioned problem may be solved by the following one solution. When a communication error where transmission, reception, or both transmission and reception of a signal is not allowed occurs between one or a plurality of a plurality of information acquisition devices that acquires states of a plurality of power storage cells and an information collection device that communicates with the plurality of information acquisition devices in a time-division manner, and collects information related to the states of the plurality of power storage cells acquired by the plurality of respective information acquisition devices, a process for resolving a communication error is executed by putting all the plurality of information acquisition devices in a state in which communication with the information collection device is allowed at all times. Here, the plurality of information acquisition devices is in a state in which communication with the information collection device is allowed in a first period in which the plurality of information acquisition devices communicates with the information collection device, and is in a state in which the state, in which communication with the information collection device is allowed, is canceled in a second period in which other information acquisition devices communicate with the information collection device in a relation of n to 1 (n is a positive natural number indicating the number of communication channels of the information collection device).
