Abstract

In some examples, an apparatus includes a controller to monitor voltage of a battery during constant current charging of the battery, and to detect lithium plating of the battery based on a rate of change of the monitored voltage of the battery during constant current charging of the battery. In some examples, a battery module includes a plurality of battery cells connected in parallel, and a controller to determine an impedance of each of the plurality of battery cells, and to disconnect one of the plurality of battery cells from the plurality of battery cells based on a relation of the impedance of the one of the plurality of battery cells with a threshold impedance.
