CHARGE AND DISCHARGE CONTROLLER, CHARGE CONTROL METHOD, DISCHARGE CONTROL METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform peak-cut while suppressing electric power charged to a secondary battery to a required minimum limit.SOLUTION: A peak-cut electric power calculation part 154 calculates peak-cut electric power capable of being transmitted to wiring 200 as monotone non-increase electric power to a resistance value of the wiring 200 between a vehicle 100 and a substation. In addition, when load electric power is the peak-cut electric power or more, a peak-cut part 156 controls charge and discharge of the secondary battery 140 with electric power of a difference between the load electric power and transmission peak-cut electric power.
