Li-Ion Battery Gradual Capacity Loss Data Clear: Description
Perform Li-ion Battery Gradual Capacity Loss Data Clear when the Li-ion battery pack assembly or Li-ion battery controller is replaced with a new one. VCM saves the Li-ion battery deterioration information sent from the Li-ion battery controller and manages the Li-ion battery replacement timing. When the Li-ion battery pack assembly or Li-ion battery controller is replaced with a new one, there is a difference between the Li-ion battery deterioration data stored in VCM and the actual Li-ion battery deterioration level. In this case, VCM will incorrectly manage the Li-ion battery replacement timing. So perform Li-ion Battery Deterioration Data Clear to clear the Li-ion battery deterioration data stored in VCM.
