An arc detection assembly is provided and includes first and second conductors including first and second terminal ends, respectively, which are engageable to form an electrical connection and a temperature sensing system. The temperature sensing system includes a temperature sensor disposed in contact with one of the first and second terminal ends and configured to sense a temperature of the one of the first and second terminal ends and a temperature monitoring circuit. The temperature monitoring circuit is coupled to the temperature sensor and configured to determine when the temperature sensor senses an increase in temperature of the one of the first and second terminal ends and to determine whether the increase in temperature is indicative of an arcing condition of the electrical connection.

A high voltage DC contactor control system. The system reduces/eliminates arcing in in contactors and includes a short circuit protection system operably connected to the drive voltage configured to reducing arcing between portions of the contactor. The short circuit protection system includes a first arc prevention element and a first arc prevention driver configured to cause the first arc prevention element to be disposed between the first and second portions of the first contactor to prevent arcing between them.
