1. A pre-charge module comprising:

  • a relay;

    a transistor connected to the relay and to a power supply; and

    a solid state device connected to a gate of the transistor, the solid state device controlling switching of the transistor such that the transistor is switched off when a voltage at a source of the transistor approaches a voltage at a drain of the transistor, to switch off the solid state device such that a capacitor is pre-charged, and providing a floating ground.
