  • Marine charge source switching system
    Patent number: 6815931
    Abstract: A battery charging system includes a first charge source for connection to a first engine and at least a second charge source for connection to at least a second engine. A first battery is connected to the first charge source. At least a second battery is connected to the second charge source. At least a third battery is provided and is connected to a load. A switch is adapted in the first mode of operation to connect the third battery to the first charge source, and in a second mode of operation to connect the third battery to the second charge source. In a third mode of operation, the switch can isolate the third battery from the first and second charge sources as a fail-safe, and provide an alarm of this status. The invention is particularly adapted for use in marine vessels to prevent start batteries from discharging to a point where the voltage is insufficient to start an engine. A switch assembly and a method according to the invention are also disclosed.
