POWER MANAGEMENT SYSTEM AND POWER MANAGEMENT METHOD

摘要

An object of the present invention is to effectively use an electric power without impairing the convenience for a user. A power management system 1 has a plurality of quick chargers 350 to which the electric power is supplied from the common electric power system, and a power management server 310 which manages electric power supplies to the quick chargers 350 from the electric power system. The quick charger 350 charges an electric vehicle with a constant-current/constant-voltage charging method. The power management server 310 has a charging-phase identification unit 312 configured to identify whether the quick charger 350 in a charging operation among the battery chargers 350 is in a constant-current charging phase or in a constant-voltage charging phase, and a power-allocation determination unit 313 configured to allocate an electric power to at least one of quick chargers 350 in the constant-current charging phase of the charging operation, from another quick charger 350 among the quick chargers 350 in the charging operation.
