Design Features



The following list indicates some of the features that have been designed to disconnect high voltage in the event of an accident.

- Inertia switches are designed to disconnect high voltage and fuel in the event of an accident. There are two inertia switches - both front and rear. If either switch opens, it disconnects the high voltage and electrical circuit to the gasoline fuel pump.

- The high voltage system is disconnected any time the vehicle ignition key is turned to the off position.

- The high voltage system is disconnected any time the High Voltage Service Disconnect Switch is removed (The High Voltage Service Disconnect Switch is located on the top of the High Voltage Battery).

- The high voltage battery contains a fuse that will open in the event of a high current short circuit.

- If the vehicle ignition key is left on, and the high voltage battery temperature exceeds 140°F, thermal sensors will disconnect the high voltage battery. Note - If the key is off, the high voltage is already disconnected.

- There is an interlock circuit on all high voltage connectors that disables the high voltage any time a high voltage wiring connector is disconnected.
