Document Type and Number:
Japanese Patent JP2023027996
Kind Code:
A
Abstract:
To realize highly efficient charging/discharging of a secondary battery.SOLUTION: A controller 100 for controlling charging/discharging of a power supply device 1 comprising a main power supply part 2 and a sub power supply part 3 thar are connected in parallel to a load L comprises relevant information indicating the relationship of a discharge current from a power supply device 1 to the load L, a discharge current ratio that is a ratio between an output current of the main power supply part 2 and an output current of the sub power supply part 3, and a power supply loss of the power supply device 1. It is so adjusted that a measurement value of the discharge current from the power supply device 1 to the load L is acquired, the discharge current ratio whose power supply loss of the power supply device 1 corresponding to the acquired measurement value of the discharge current from the power supply device 1 to the load L becomes minimum is determined from the relevant information, and the discharge current ratio is made to become the discharge current ratio determined from the relevant information.SELECTED DRAWING: Figure 1
