  "textContent": "An electric vehicle includes a main battery, an auxiliary battery, a power load, a power converter, a switch, a memory, and a controller. The controller controls the switch. When the switch is turned on, the low voltage power converted in the power converter is provided to the auxiliary battery thereby charging the auxiliary battery, and when the switch is turned off, the auxiliary battery is discharged. When the auxiliary battery is charged after the vehicle is turned off, the controller obtains the output current value of the power converter. The controller determines the state-of-charge (SOC) of the auxiliary battery based on the obtained output current value of the power converter, based on a correspondence relationship between an output current value of the power converter and an SOC of the auxiliary battery at the time when the auxiliary battery is charged after the vehicle is turned off.",
