The precharge circuit should be disconnected:

  1. When the difference between battery-pack voltage and bus voltage drops below some small design threshold

  2. When the electrical current flowing through the battery pack drops below some small design threshold

  3. When the temperature of the precharge resistance exceeds some design threshold

  4. After the precharge circuit has been activated for a specified period of time
