Abstract: A battery module is disclosed having a string of series-connected battery cells, three terminals, a battery management system (BMS) circuit, and a voltage source converter (VSC) to selectively connect the positive and negative ends of the string of cells to the three terminals. The unique configuration of the battery module allows it to output power in DC, 1-phase AC, and 3-phase AC forms under the control of the BMS circuit. A power system is disclosed utilizing configurable battery modules to provide DC, 1-phase AC, and 3-phase AC power to one or a plurality of system components.

Abstract: A power system for a vehicle or a stationary installation is disclosed comprising a battery pack having a plurality of removable battery modules, each battery module having an internally controllable connection to a common power bus, a system component controlled by a Power Controller Unit (PCU), said PCU having a connection to said common power bus, and a System Control Unit (SCU) being in communication with each of said battery modules and said PCU, said SCU receiving control inputs from the Operator of the power system. In some embodiments, said Operator may be a human operator, an Electronic Operator Unit (EOU), or a combination thereof. A method is disclosed for operating the internally controllable connection of each of the battery modules responsive to the control inputs received by the SCU from the Operator of the power system and the monitored status of the power system.

Abstract: A battery cell monitoring and conditioning circuit is disclosed to facilitate low cost manufacture of battery modules comprising a plurality of series connected cells. A battery management system utilizing a plurality of series connected cell monitoring and conditioning circuits is disclosed. Methods are provided for operating the disclosed circuits.
