An intelligent instrumentation system for testing fast-charging process in high-capacity batteries

This paper describes a new system for testing fast-charge process in medium or high capacity batteries. The developed system integrates high-efficiency power stages (in order to implement different charging methods) and signal conditioning stages (main battery parameters are sampled to provide information about battery behavior). In this way, it is possible to study the efficiency of fast-charging methods. Due to the data obtained being processed and monitored online in a personal computer (both manual or automatic control of test is possible), different charge-end point detection methods can also be implemented.
