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.

Abstract translation: 电池充电系统包括用于连接到第一发动机的第一充电源和用于连接至少第二发动机的至少第二充电源。 第一电池连接到第一充电源。 至少第二电池连接到第二电荷源。 提供至少三个电池并连接到负载。 开关适于在第一操作模式中将第三电池连接到第一充电源，并且在第二操作模式中将第三电池连接到第二充电源。 在第三种操作模式下，开关可以将第三电池与第一和第二充电源隔离成故障保护，并提供该状态的警报。 本发明特别适用于船舶用于防止起动电池放电到电压不足以起动发动机的点。 还公开了根据本发明的开关组件和方法。
