The present invention relates to a method and a circuit for determining the charging current (IL) and the temperature (T) of an accumulator (AKK). According to this method, a part of the charging current (IL) is amplified using a transistor (V) which is in thermal contact with the accumulator. The output voltage (UA) of a transistor amplification circuit is measured for determining a reference value (UA,Ref) only once and at a given temperature. The output voltage (UA,O) is then measured at the temperature to be determined when the charging current is not transmitted, and the output voltage (UA,I) is determined at the same temperature when the charging current (I) is transmitted. The temperature and the charging current (I) are calculated from the reference value (UA,Ref) and the voltage (UA,O) when the charging current is not transmitted, and from the voltage (UA,I) when the charging current is transmitted. |
