Abstract: In a method of controlling discharge of a battery in a vehicle that generates driving power using electric power to prevent deterioration of the durability of the battery and ensure the stability of the battery, a controller is configured to monitor the state of charge (SOC) value of a first battery configured to supply the electric power to a driving unit of the vehicle and an SOC value and a temperature of a second battery configured to charge the first battery. When the SOC value of the first battery reaches a predetermined first SOC value, the controller is configured to discharge the second battery and charges the first battery in response to the discharging of the second battery. When the SOC value of the second battery reaches the first SOC value, the controller ends the discharging of the second battery.
