ABSTRACT:
Disclosed is a battery disconnection detecting apparatus which can accurately detect whether or not the interruption of electric power supply from a battery to a storage device is continuously caused by the disconnection of an electric power line, or the like. The voltage of a battery is continuously supplied to a backup RAM through a second electric power line. An EEP-ROM is provided which can hold the stored data even when electric power supply is interrupted. When a power switch is turned ON, and an ECU is operative, a CPU detects the interruption of the electric power supply through the second electric power line based on the state of a standby bit. After detecting the interruption of the electric power supply, the CPU makes the count of the counter in the EEP-ROM count up. When the count reaches or exceeds the preset number n, i.e., when the CPU detects the interruption of the electric power supply consecutively for the preset number of times n or more, it is judged that the interruption of the electric power supply is continuously caused by the disconnection of the second electric power line.
