Abstract
A multicell battery power system for providing power to a load is disclosed. The battery power system includes a plurality of battery modules and power bus for transmitting power between the battery modules and the primary load. Each of the battery modules includes a battery for providing electrical power and connection circuitry for connecting the battery to the power bus. The battery modules each include circuitry for monitoring the power output and status of the battery means. Each battery module also includes a programmable battery controller for controlling the operation of the battery and the connection circuitry. The battery controller is programmably responsive to the power monitoring circuitry, and in an illustrated embodiment is also be responsive to a system power controller or to one or more other battery modules. A battery charger may also be included in each module to provide programmably controlled individual recharging of batteries by module.
