<P>PROBLEM TO BE SOLVED: To provide a battery temperature detecting device capable of improving sensitivity of an input analog signal which is temperature information of a battery cell, in a predetermined range. <P>SOLUTION: The battery temperature detecting device according to the present invention includes an analog output amplifier 14 for converting and outputting an input analog signal that is temperature information of a battery cell 20, into an output analog signal using a predetermined primary function. In the primary function used by the analog output amplifier 14, a predetermined range of the input analog signal is defined as a sensitivity improving range, and the absolute value of a gradient in the sensitivity improving range is larger than the absolute value of a gradient in a sensitivity non-improving range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
