The development process and application of a microcomputer system for secondary battery testing is described, with specific application to the development of the zinc-ferricyanide hybrid redox battery. System development begins with the layout of the logic processes conducted during the battery cycle sequence. In the development of a microcomputer system one should be aware of certain electronic traps, software bugs, and unanticipated hidden costs. System cost trade-offs occur when selecting the A/D converter. The decision of whether to use 8- or 12-bit resolution in the A/D converter is a serious one. The macroprocessor language Tiny Basic was selected. The system developed is capable of controlling the charge and discharge cycles of 6 or more secondary batteries based upon various operator-determined cell parameters, and computing at the end of each cycle the voltaic, coulombic, and energy efficiencies for each cell independently. These efficiencies and the cell parameters are then logged for later data manipulation and graphic representation. 2 figures. (RWR)
