Abstract

A battery management system (100) comprises input means (102) for receiving input signals, such as current or voltage, which represent a physical quantity of a battery. In operation, processing means (105) of the battery management system (100) calculate a physical quantity of the battery, such as the State of Charge, based on the input signals by using an electrochemical/physical model of the battery. The model includes a representation of a main electrochemical storage reaction, whose behaviour is calculated in dependence on a battery temperature. The processing means (105) calculates the battery temperature based on a temperature model of a temperature development in the battery. The battery management system (100) comprises output means (104) for outputting an output signal which is derived from a state of the electrochemical storage reaction. The battery management system (100) is, advantageously, used in a smart battery (10) or a battery charger/discharger (200). The model is, advantageously, also used in a battery simulator.
