Abstract
An electric vehicle may include a battery; an inverter; a motor; a first and second terminal configured to connect to an external power supply; a first wire connecting the first terminal to a neutral point; a second wire connecting the second terminal to the battery, a first relay disposed on the first wire; a first and second voltage sensor configured to measure a potential difference; and a controller. The controller may be configured to: calculate permissible power of the battery; calculate a first voltage value obtained by adding a first margin to a detected value by the first voltage sensor; calculate a second voltage value obtained by adding a second margin to a detected value by the second voltage sensor; and calculate a current command value to the external power supply based on the permissible power and a smaller value of the first voltage value and the second voltage value.
