Abstract: A power system for a vehicle or a stationary installation and a method of operating a battery module. The power system includes an electronic operator unit, a power control unit, a system control unit, and a battery pack. The power control unit is coupled to a system component and has a predetermined power demand. The system control unit generates a power system data map and is communicatively coupled to a pack communications bus, the electronic operator unit, and the power control unit. The battery pack has a plurality of sockets. The power bus is coupled to the plurality of sockets and to the power control unit. The power bus includes a negative power bus and a positive power bus.

Abstract: A battery module is disclosed having a plurality of series-connected battery cells contained in, and electrically isolated from, an enclosure, with a first internal relay to control connection between cells and a positive terminal, and a second internal relay to control the connection between cells and a negative terminal. A control signal input is provided to control the relays. An embodiment is disclosed wherein the relays are of distinct types. An embodiment is disclosed having an internal battery management system which controls the relays in response to a digital message. A modular battery pack is disclosed consisting of a plurality of modules connected in parallel, which can be individually and independently activated and deactivated. A method is provided for activating an individual module.
