摘要: A power supply system includes a main line, a plurality of sweep modules, and a control unit. Each sweep module includes a battery module and a power circuit module. The power circuit module switches between connection and disconnection between the battery module and the main line. The control unit executes sweep control for sequentially switching the battery modules which are to be connected to the main line. The control unit maintains connection of a refreshing module which is to be subjected to refreshing charging/discharging to the main line while sweep control is being executed in a state in which the refreshing module is excluded in at least one of outputting of electric power to the outside and inputting of electric power from the outside.

摘要: A power supply system disclosed here is connected to an electric power system through a distribution device. The power supply system includes a plurality of strings connected to the distribution device and a failure detector. The failure detector of the power supply system is configured to perform a first process of connecting at least one battery module to a main line to set a voltage detected by a string voltage detector at a voltage higher than a predetermined voltage in a state where a switch disconnects the distribution device and the main line, a second process of sending a disconnecting signal for disconnecting all the sweep modules from the main line, and a third process of determining whether the voltage detected by the string voltage detector is lower than the predetermined determination voltage or not after the second process.

摘要: A power supply system includes a plurality of sweep modules, a defect detecting unit, and a control unit. Each sweep module includes a battery module and a power circuit module. The defect detecting unit detects a defect for each sweep module. The number of sweep modules is greater S (S≥2) than a minimum number of sweep modules required for operation. When the number of defective sweep modules in which a defect has been detected is equal to or less than F (2≤F≤S), the control unit is configured to disconnect the defective sweep modules from a main line and to continuously execute sweep control.
