Abstract: The present invention provides a central current share coordinator for use with remotely and non-remotely controllable rectifiers coupled to an output bus. In one embodiment, the central current share coordinator includes a rectifier current resolver configured to determine an existing current share condition for the remotely and non-remotely controllable rectifiers. Additionally, the central current share coordinator also includes a load share adjuster coupled to the rectifier current resolver and configured to adjust an output current of the remotely controllable rectifiers toward a target current share distribution on the output bus.

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.

Abstract: A self-correcting and adjustable apparatus and method of predicting remaining capacity (Q) and reserve time (t) of a discharging battery to a selected end voltage determined by an arrangement considering the open circuit voltage (E.sub.oc), battery voltage (V) battery temperature (T) and battery internal resistance (R.sub.int). The apparatus and method of the present invention utilize a calculation process which first compares calculated and measured capacity discharged between two times (Q.sub.dis.calc. -Q.sub.dis.act.). If this difference exceeds a certain predetermined tolerance or limit of error, the calculation process is adjusted or tuned and the comparison is repeated until the difference between the actual capacity and the calculated capacity are within a predetermined tolerance. The calculation process is tuned by adjusting the value attributed to the battery's internal resistance (R.sub.int).
