Abstract
When charging is performed at home of a user of a vehicle, a processor performs first charging control to start the charging after an elapse of a standby time based on a time required for elimination of polarization of a battery pack and, when the charging is performed at a place other than the home, the processor performs second charging control to start the charging before the elapse of the standby time. The processor performs control to estimate the SOH, after each of the first charging control and the second charging control.
Claims5
A charging control device that performs control for charging of a secondary battery mounted on a vehicle, the charging control device comprising:
- a first processor that performs control to estimate a state of health SOH of the secondary battery, using an amount of change in a state of charge SOC of the secondary battery at a time when the charging has been performed and using an amount of charging power at the time when the charging has been performed;
- and
- a second processor that controls the charging, wherein
- when the charging is performed at home of a user of the vehicle, the second processor performs first charging control to start the charging after an elapse of a predetermined pre-charging standby time based on a time required for elimination of polarization of the secondary battery, and
- when the charging is performed at a place other than the home, the second processor performs second charging control to start the charging before the elapse of the pre-charging standby time, and
- the first processor performs control to estimate the SOH after the charging by the first charging control or the second charging control is completed.
