Abstract
A method for detecting abnormal self-discharge in a battery system by monitoring the balancing charge for each cell and a battery system which is configured to use this method are provided. The method makes it possible to predict the probability of the occurrence of a safety-critical state, for example, an internal short circuit, with the result that suitable countermeasures can be taken in good time.
