Charging system for diverse batteries
View Patent ↗A power system includes a plurality of storage battery facilities constructed to be interconnected to an electric power grid, and a multi-storage battery control apparatus configured to control the plurality of storage battery facilities, the plurality of storage battery facilities include a first storage battery facility including at least one first storage battery, and a second storage battery facility including at least one second storage battery, the first storage battery is different from the second storage battery in type, and the multi-storage battery control apparatus is constructed to selectively use the first storage battery facility or the second storage battery facility in accordance with a plurality of different types of application.
1. A power system comprising:
a plurality of storage battery facilities; and
a multi-storage battery control apparatus configured to control the plurality of storage battery facilities,
wherein the plurality of storage battery facilities comprise a first storage battery facility including at least one first storage battery, and a second storage battery facility including at least one second storage battery, the first storage battery being different from the second storage battery in type,
the multi-storage battery control apparatus is constructed to selectively use the first storage battery facility or the second storage battery facility in accordance with a plurality of different types of charge-discharge application,
the multi-storage battery control apparatus is constructed to respectively calculate a first charge-discharge amount for first charge-discharge application and a second charge-discharge amount for second charge-discharge application different from the first charge-discharge application, control charge-discharge of the first storage battery facility on a basis of the first charge-discharge amount, and control charge-discharge of the second storage battery facility on a basis of the second charge-discharge amount,
the multi-storage battery control apparatus is constructed to execute:
processing of acquiring the first charge-discharge amount as normal operation application while power outage does not occur at an electric power grid which is interconnected to the plurality of storage battery facilities;
processing of acquiring the second charge-discharge amount as backup application while power outage occurs at the electric power grid;
processing of, in a case where power outage does not occur at the electric power grid, controlling charge-discharge of the first storage battery facility on a basis of the first charge-discharge amount and setting a charge-discharge amount of the second storage battery facility at 0; and
processing of, in a case where power outage occurs at the electric power grid, setting a charge-discharge amount of the first storage battery facility at 0 and controlling charge-discharge of the second storage battery facility on a basis of the second charge-discharge amount.
2. The power system according to claim 1 ,
wherein the plurality of storage battery facilities include a different type mixed storage battery facility including a plurality of different types of storage batteries, and
the multi-storage battery control apparatus is further constructed to execute:
processing of acquiring respective pieces of storage battery information of the plurality of storage batteries included in the different type mixed storage battery facility, and computing combined storage battery information by combining the acquired respective pieces of storage battery information to one piece; and
processing of diagnosing a state of the different type mixed storage battery facility on a basis of the combined storage battery information.
