Abstract
A storage battery control device includes a storage battery control method, a program, a power storage system and a power supply system which can fulfill better performance with a configuration where a plurality of storage batteries are connected. A storage battery to be charged is determined based on the states of charge and the numbers of times of charge/discharge obtained from the plurality of storage batteries referring to a charge order table to which an order to charge storage batteries is set according to states of charge and numbers of times of charge and discharge of storage batteries to be charged with power. The order to charge the storage batteries is preferentially set to a row of cells whose numbers of times of charge and discharge are small and is preferentially set to cells of each row whose states of charge are low in the charge order table.

10. A storage battery control device comprising:
-
a setting unit configured to be set in advance with an order to charge or discharge a storage battery according to at least two parameters configured to define an operating life and an output of the storage battery configured to store power; a determining unit configured to determine the storage battery to be charged or discharged among a plurality of storage batteries based on the parameters obtained from the plurality of storage batteries referring to the order set in advance to the setting unit; an obtaining unit configured to obtain the parameters from the plurality of storage batteries; and a deciding unit configured to decide that the determining unit performs processing of determining the storage battery to be charged or discharged when the parameters obtained by the obtaining unit from the storage battery which is being charged exceed a predetermined threshold. - View Dependent Claims (11, 12, 13)
