Abstract: A system includes a first circuit in which storage battery units are connected in series, second circuits, adjusters that adjust the amounts of the currents flowing through the second circuits, and a controller that performs at least one of first control and second control. The first control is control in which the controller causes the adjusters to make the voltage of a first storage battery unit higher than the voltage of a second storage battery unit having a higher degree of degradation than the first storage battery unit by adjusting the amounts of the currents flowing through the second circuits and then stops a charge. The second control is control in which the controller causes the adjusters to make the voltage of the first storage battery unit lower than the voltage of the second storage battery unit by adjusting the amounts of the currents flowing through the second circuits and then stops a discharge.

Abstract: A recognition interface recognizes a reverse flow state in which power flows from a customer's site to a power system or a forward flow state in which power flows from the power system to the customer's site. When the recognition interface recognizes a reverse flow state, a controller causes at least one of a first power storage system through a third power storage system to be charged, based on a priority level related to charge defined for the first power storage system through the third power storage system. When the recognition interface recognizes a forward flow state, the controller causes at least one of the first power storage system through the third power storage system 40c to be discharged, based on a priority level related to discharge defined for the first power storage system 40a through the third power storage system.

Abstract: A server apparatus obtains, via an information terminal wirelessly connected to an electrical-power storage device, a value indicating a state of the electrical-power storage device at an end of use of electric equipment having the electrical-power storage device. The server apparatus further obtains, via the information terminal wirelessly connected with the electrical-power storage device, a value indicating the state of the electrical-power storage device at a start of the use of the electric equipment. The server apparatus then detects an abnormality in the electrical-power storage device by using the value indicating the state of the electrical-power storage device at the end of the use and the value indicating the state of the electrical-power storage device at the start of the use.

Abstract: A method is provided that includes: receiving identification information of a power storage device that is connected to a charging device, and a value indicating the state of a storage battery included in the power storage device. The method also includes associating to each other and storing the identification information of the power storage device and the value indicating the state of the storage battery. Additionally, the method includes determining the possibility of charging the power storage device by comparing the received value indicating the state of the storage battery with a value indicating a past state of the storage battery that is stored and corresponds to the received identification information of the power storage device. The method further includes transmitting information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device.

Abstract: A first connector for electrically connecting a first unit power terminal through a third unit power terminal to a power converter for performing conversion between a DC power and an AC power is mounted to a mounting port. In a status in which the first connector is being removed from the mounting port, it is impossible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are inputting and outputting a DC power, and it is possible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are not inputting and outputting a DC power.
