Abstract
A central contactor controller for a battery plant containing a power supply couplable to a source of AC power and a battery via a bus, the bus further couplable to a load to supply power thereto, and a method of operation thereof. In one embodiment, the controller includes: (1) a sensor that senses operational states of the power supply and the battery and (2) central control circuitry, coupled to the sensor and couplable to distributed contactors associated with the battery and the load, that provide control information to distributed control circuitry associated with the distributed contactors in response to the operational states, the distributed control circuitry employing the control information to control the distributed contactors selectively to couple the battery and the load to the bus.
