ABSTRACT:
A battery charger for charging an electric battery pack has a supply rectifier connectable to the battery pack via a thyristor. A thermistor is mounted on a mechanical structure and brought into thermal contact with a cell of the battery pack to measure the temperature thereof. Comparators control the firing of the thyristor in dependence on the state of the thermal conductive relationship between the thermistor and the cell and also upon dependence of a correct electrical connection between the thermistor and the battery pack.
