Battery controller, management system, battery control method, battery control program, and storage medium
A battery controller has a holder, a calculator, an acquirer, a calculator, and a controller. The holder holds, at a predetermined time, a value of a received power supplied from an electrical power receiving system to equipment supplied with power from a rechargeable battery. A calculator calculates a difference between a present value of the received power and a last-held value of the received power last-held by the holder at the predetermined time. An acquirer acquires a command value of the received power for each predetermined time period defined by a predetermined time interval. A calculator calculates a limit value of the received power for each time that is shorter than the predetermined time, based on the command value of the received power for each predetermined time period. A controller controls charge and discharge in the rechargeable battery, based on the calculated difference and on the limit value.
