Abstract (en)
[origin: WO2007148299A2] A device includes a power management system. The power management system has a circuit including a connection for a power source, a connection for a load, a connection for a first electrical storage battery and a connection for a second electrical storage battery. The circuit includes switches for selectively connecting each of the storage battery connections to the power source connection in a circuit wherein current may only flow to the battery connection. The circuit includes switches for selectively connecting each of the storage battery connections to the load connection in a circuit in which current may only flow from said battery connection. A controller is programmed to select a battery to be on load and a battery to be on charge. The controller provides output signals to the switches to connect the connections for the battery on load to the load connection and not to the power source connection, and to connect the battery on charge to the power source connections and not to the load connection. Other inventions are also disclosed.
