The voltage protection device (VPD) system is primarily designed to create an open in the series circuit in the high voltage battery. This ensures that the battery does not become overcharged, which could lead to dangerous conditions, including potential fire hazards. By interrupting the circuit, the VPD effectively protects the entire electrical system of the vehicle from damage.
Additionally, the VPD may turn off the Power Relay Assembly (PRA) if battery expansion occurs due to an overcharge condition. This is a crucial safety feature, as it prevents further electrical flow and minimizes the risk of battery failure or accidents, showcasing the importance of voltage management in electric and hybrid vehicles.
