ABSTRACT:
A battery scanning system which is capable of monitoring and displaying the oltage of each cell in a battery or upon command provides the cell voltage distribution by displaying the cell number and voltage value of highest and lowest cell. The system has a digital logic system, display, input switches for operator generated variables, an alarm, relays, relay selection gates, an optically coupled isolation amplifier, power source and an analog-digital converter. The optically coupled analog amplifier electrically isolates the system from the battery so that large voltage offsets will not adversely affect the automatic measuring of the cells.
