Abstract
A temperature/voltage detecting unit has a temperature detector and a voltage detector. The temperature detector has a light electric system stabilized power supply for stabilizing a light electric system power supply voltage, a temperature resistance element provided close to a corresponding battery element, for changing its resistance value based on a change in temperature, and a voltage-to-frequency converter operating based on a voltage from the light electric system stabilized power supply, for detecting a terminal voltage of the temperature resistance element to which a constant current flows from the light electric system stabilized power supply, converting this value into frequency information and outputting the frequency information. The voltage detector has a heavy electric system stabilized power supply for stabilizing a voltage supplied from the corresponding battery element, a voltage supply control section for inputting a signal to show whether or not the light electric system power supply voltage is being applied to the temperature detector, and, when this voltage is being supplied, for applying a voltage from the corresponding battery element to the heavy electric system stabilized power supply, and a voltage-to-frequency converter operating based on a voltage from the light electric system stabilized power supply, for detecting a terminal voltage of the corresponding battery element, converting this value into frequency information and outputting the frequency information.
