Abstract
A charging device includes a charging port, an onboard battery, and a control device. The charging port can be electrically coupled to an external power source. The onboard battery can be electrically coupled to the charging port. The control device is configured to charge the onboard battery with power supplied through the charging port. The control device includes one or more processors and one or more memories. The one or more processors are configured to execute a process including suspending the charging of the onboard battery at a prescribed timing during the charging of the onboard battery, discharging at least some of the power in the onboard battery from the onboard battery when the charging of the onboard battery is suspended, measuring a voltage of the onboard battery after the discharging, and deriving a state of charge of the onboard battery, based on the measured voltage of the onboard battery.
