Multiple choice. Choose the best answer: The voltage protection device (VPD) system is designed to do which of the following? Make the vehicle operate in reduced power mode. create an open in the series circuit in the high voltage battery. Discharge the inverter capacitor. Turn off the PRA if battery expansion occurs due to an overcharge condition.

The **Voltage Protection Device (VPD)** system is primarily designed to ensure the safety and integrity of the vehicle's electrical system by preventing potential damage due to abnormal voltage conditions. **Best Answer:** **Create an open in the series circuit in the high voltage battery.** **Explanation:** The VPD monitors the voltage levels within the high voltage battery. If it detects an overvoltage or undervoltage condition that could potentially harm the battery or other components, the VPD will create an open circuit in the series connection of the high voltage battery. This action effectively isolates the battery from the rest of the system, preventing further electrical issues or hazards. **Other Options:** 1. **Make the vehicle operate in reduced power mode:** While some systems may adjust power levels under certain conditions, this is not the primary function of the VPD. 2. **Discharge the inverter capacitor:** This is typically managed by other components within the system, not specifically by the VPD. 3. **Turn off the PRA if battery expansion occurs due to an overcharge condition:** This is a more specific action that might be part of broader protective measures, but the primary role of the VPD is to manage the circuit's continuity based on voltage levels. **Final Selection:** **Create an open in the series circuit in the high voltage battery.**
