Abstract:
1. A disconnect switch module for disconnecting a battery bank from an electrical load upon occurrence of certain conditions, the module comprising one or more pairs of high-current, high-side solid state switch devices, the devices of each pair each comprising a solid-state switch comprising a source terminal and a drain terminal providing a conduction path through the switch, the source terminal of one device of each pair being connected to the load circuits, the source terminal of the other device of each pair being connected to the battery bank, and the drain terminals of the devices of each pair being connected in common further comprising a processor that is associated with each solid-state switch and that comprises an algorithm for processing data corresponding to battery bank voltage for causing the solid-state switches to disconnect the battery bank from the electrical load when data corresponding to battery bank voltage indicates that a battery has been connected in the battery bank to create a double battery.
