Abstract:
1. A power system having a plurality of power storage units each being rechargeable, comprising: a power line electrically connecting a load device and said power system; a plurality of converter units provided between said plurality of power storage units and said power line, respectively, each being capable of controlling charging/discharging of a corresponding power storage unit; temperature obtaining unit for obtaining a temperature of each of said plurality of power storage units; target power value determining unit for determining a target power value for each of said plurality of power storage units, by distributing a required power value from said load device in accordance with temperatures of said plurality of power storage units obtained by said temperature obtaining unit; and converter control unit for controlling said plurality of converter units in accordance with said target power value determined by said target power value determining unit, wherein said target power value determining unit determines said target power value such that a difference in distributed power value between a power storage unit and another power storage unit gradually increases/decreases with an increase/decrease of the difference in temperature there between.
