摘要： A method may include receiving a discharge request to perform discharge of a capacitor (106) of an electric vehicle; closing a first switch (118) a first circuit (116) provided in parallel with a second circuit (110) of the electric vehicle; determining a voltage drop of the capacitor, based on closing the first switch (118); and closing a second switch (112) of the second circuit (110) to perform the discharge of the capacitor (106), based on the determining the voltage drop of the capacitor (106) indicating that a battery of the electric vehicle is disconnected from the capacitor (106).
