Abstract: An energy management system (controller) operates on a charging voltage Vba of a specified storage battery out of storage batteries to control power converting operations by bidirectional DC/DC converters. The energy management system controls the power converting operations of the respective bidirectional DC/DC converters so that the SOC of the specified storage battery is always higher than the SOCs of the other storage batteries, executes supplying of power from the other storage batteries to the DC bus with priority over supplying of power from the specified storage battery to the DC bus, and causes the corresponding bidirectional converters to stop the supplying of power from the other storage batteries the DC bus when the SOCs of the storage batteries have fallen below a lower limit value set in advance due to the supplying of power to the DC bus.

Abstract: Fluctuations in the battery life of a plurality of storage batteries are reduced. A DC power supplying system includes power conditioners that supply generated power of power generators to a DC bus, converters that perform voltage conversion on a bus voltage and supply load power to load appliances, bidirectional converters that execute charging operations that charge storage batteries and discharging operations that discharge the storage batteries, and an energy management system that causes the converters to execute a charging operation when the generated power exceeds the load power and to execute a discharging operation when the generated power is below the load power. During a charging operation, the energy management system applies a first voltage-current characteristic that linearly increases the charging current in keeping with an increase in the bus voltage to each bidirectional DC/DC converter with a slope in keeping with the SOC of a storage battery.
