ABSTRACT
The paper presents an approach to the modelling of a cyclic battery tester and contains important information about Li-ion batteries, charging/discharging procedures, conditions and protections, which must be observed during the testing process. The main goal was to create and simulate a schematic, which will be capable of cyclically test Li-ion battery cells. Regulation of the final schematic is based on cascade connections of operation amplifiers, which works as a voltage source with current limiting functions. The power part is created by two MOSFETs connected as a half-bridge. This topology allows to flow current both directions (from and to the battery). Final simulation is supplemented by protections such as reverse polarity protection, short circuit protection and overvoltage protection during charging. Proper operation of the whole connection is demonstrated by the simulation outputs in the last section.
