Battery system for vehicle, has comparator for generating alarm signal in response to comparison between battery module instantaneous voltage and predicted battery module voltage, where comparison is based on battery module parameters

摘要

The battery system (300) has a battery with a battery module (302) that is provided with multiple battery cells (304), while the battery model parameters of the battery are detected and provided by a battery management unit. The battery cells are monitored by a battery cell monitor unit (308) and an electronic safety system (306) is provided for the battery module. An alarm signal (314) is generated by a comparator (312) in response to the comparison between a battery module instantaneous voltage and a predicted battery module voltage. The comparison is based on the battery module parameters.
