Abstract
The invention relates to a method for operating intrinsically safe battery cells after charging of an intrinsically safe battery cell at a low temperature. In accordance with the invention, provision is made here for the determination of the discharge curve of the battery cell to then be performed, for the discharge curve of the battery cell to be analyzed in respect of the presence of plating criteria and for a change to operation in a monitoring mode to be made if at least one plating criterion is present, wherein the capacity of the intrinsically safe battery cell is monitored in the monitoring mode. The invention furthermore relates to an intrinsically safe battery cell which is designed for implementing the method.
