    摘要： A battery device includes electric cells connected in series, resistors connected to respective electrodes of the electric cells, discharge switches for discharging voltages between the respective electrodes of each of the battery cells via the resistors, and a voltage detection and control circuit. When a detection voltage when the discharge switch is closed and not disconnected is defined as V, a detection voltage when a discharge switch is closed and disconnected is defined as VS, and a detection voltage when a discharge switch is not closed and not disconnected is defined as VE, the voltage detection and control circuit arranges a relationship between a disconnect determination voltage VSL and a discharge malfunction determination voltage VSH so as to be VE>VSH>V>VSL>V. The battery device includes a method of making a malfunction detection signal for determining the battery device as a malfunction when at least one of voltages of the electric cells detected when closing the discharge switch is determined to be the discharge malfunction determination voltage VSH or more, or the disconnect determination voltage VSL or less.

    摘要： According to one embodiment, a temperature detection circuit is provided which requires only a small number of additional components, thus minimizing an increase in costs and which offers an insulating property and high responsiveness. A temperature detection circuit outputs a first PWM signal corresponding to a temperature of a first temperature sensor from a photointerrupter as a signal insulated from the first temperature sensor. A temperature detection circuit outputs a second PWM signal corresponding to a temperature of a second temperature sensor from a photointerrupter as a signal insulated from the second temperature sensor. A controlling arithmetic apparatus calculates a higher one of the temperatures detected by the first and second temperature sensors based on the PWM signals output from the photointerrupter.
