BATTERY CONDITION MONITORING

摘要

The present invention provides a system for determining the state of charge of a battery. The system includes a battery model having an input configured to receive an estimated state of charge value. The battery model is configured to generate at least one voltage loss output from which an estimated battery voltage is determined, the or each voltage loss output being representative of the contributions to voltage loss due to a parameter. The system also includes a comparator configured to determine a voltage error between the estimated battery voltage and the actual battery voltage. The battery model is configured to modify an adaptive state of charge weight based on the determined voltage error, and the state of charge is determined by modifying the estimated state of charge with the adaptive state of charge weight.
