METHOD FOR MONITORING A CHARGING PROCESS OF A BATTERY

摘要

A method is described for monitoring a charging process of a battery (20), in which cell voltages of a plurality of battery cells (21) are measured (S11) at regular time intervals, and loading of the battery (20) by a process of switching on an additional electrical load is prevented (S16) if the measured cell voltage of one battery cell (21) exceeds (S14) a predetermined cell voltage threshold value. A motor vehicle is also proposed, which is designed to carry out the method according to the invention during a battery charging process. In addition, a battery system is described, in which a controller (25) is designed to determine an estimated value as a function of measured battery parameters during a charging process of the battery (20), which estimated value corresponds to the maximum temperature in the battery (20) if the charging process is continued without interruption.
