Abstract

There is a request for charging and discharging of a lithium-ion battery with as less degradation as possible. In an operation using only binary values as in conventional technology, however, in a charged state in which the battery is used, there is a high possibility that the battery is used toward accelerating the degradation thereof. In a power distribution device for distributing power between a plurality of batteries and a plurality of customers, when distributing the power of the batteries to the loads of the customers, by being based at least on the degradation information of the batteries, the state of charge, and the temperature data of the batteries, a battery discharging function is achieved that makes the degradation of the batteries minimum.

Dependent claims

A power distribution device connected with a plurality of storage batteries and with a load device consuming electric power and operative to distribute electric power from the storage batteries to the load device, said power distribution device comprising:

an acquisition portion for acquiring deterioration degree information indicating degrees of deterioration of the storage batteries from the storage batteries;
a decision portion for making a decision as to which of the storage batteries is discharged first out of the plurality of storage batteries, based on the acquired deterioration degree information;
and
a transmission portion for issuing an instruction for electrical discharge to the storage battery decided to be discharged first.
