ABSTRACT:
A battery analyzer for testing industrial batteries under a constant current load. The analyzer includes a load bank consisting of a plurality of resistors in selective parallel interconnection. The load bank is placed across the battery terminals. Sensors are connected to each of the cells of the battery, as well as the battery terminals, and a multiplexer scans each of the cells and the battery terminals to monitor load current, battery voltage, and the cell voltage of each of the cells. The load bank is continually adjusted to maintain a constant current. The principal control element of the battery analyzer is a microprocessor chip which interrelates with a keyboard for receiving data from an operator. A printer, controlled by the microprocessor, presents a permanent record of the battery analysis, while a display unit, under program control, directs an operator in the use of the analyzer.
