Support of Multiple Chemistrie

Impedance Track™ devices rely on a fixed open circuit voltage (OCV) table to determine the state of dharge (SOC), where OCV (SOC) dependence is defined by cell chemistry. Impedance Track™ devices come preprogrammed to support the most common Li-Ion cells with LiCoO2 cathode and graphitized carbon anode. However, multiple other chemistries are grouped under Li-Ion; two examples of which are Co/Mn oxide cathode cells and Ni/Co/Mn cathode cells. Therefore, Impedance Track™ devices are designed with the ability to be programmed with any Li-Ion chemistry OCV table. The process of selecting the correct chemistry OCV table for a particular cell and the specifics of correctly programming this information during production are described in this document.
