Temperature detecting apparatus
First Claim
1. A temperature detecting apparatus which detects a temperature of an assembled battery in which a plurality of cells are assembled, the temperature detecting apparatus comprising:
- a plurality of detecting circuits which respectively correspond to the plurality of the cells,a pair of detection lines which electrically connects the plurality of the detecting circuits in parallel, anda processing part which outputs a sine-wave detection signal to the pair of the detection lines through a voltage-dividing resistor so as to detect a temperature of each of the plurality of the cells,wherein each of the plurality of the detecting circuits includes a circuit in which a temperature-sensitive resistor whose electrical characteristic changes responding to a temperature, a coil and a capacitor are connected in series.
