High Voltage Capacitor Discharge during Crash in Automobiles

Author : Sunitha S 1 Dr. R. Karthikeyan 2

Date of Publication :7th August 2016

Abstract: During a vehicle crash or other vehicle damaging event, may cause unwanted electrical connections and the discharge of various fluids from the vehicle to occur. Because of the significant electrical power that is stored in the HV capacitor connected in parallel with the high voltage battery, it could cause potentially hazardous situations, such as electrifying of vehicle parts, fire hazards etc. The system/method disclosed here is of discharging a high voltage capacitor in the event of a crash. This system includes a discharge circuit having a HV battery, and a load for discharging the battery.
