Abstract
A signal generation circuit () generates a pilot signal for communication between a vehicle equipped with a battery device, and a charging cable. The circuit () includes a circuit (A) includes an operational amplifier (OP) for outputting the pilot signal, a first input unit () for supplying a non-inverted input terminal of the amplifier (OP) with a first or second signal, a second input unit () for supplying an inverted input terminal of the amplifier (OP) with a first or second voltage, and a control unit () for controlling each output of the first and second input units (). Each of the first signal and the first voltage is a zero voltage. The circuit (A) is configured so that the amplifier (OP) outputs a zero voltage if the first signal is supplied to the non-inverted input terminal and the first voltage is supplied to the inverted input terminal.
