Abstract: PURPOSE: A system and method for sensing and calibrating a voltage of an electric vehicle are provided to enable a CPU to obtain calibrating information using two point voltage values obtained by a variable gain amplifier, thereby accurately calibrating a sensing value. CONSTITUTION: A device for sensing and calibrating an inverter voltage includes a battery voltage sensor(12), an inverter voltage sensor(22), a battery controller(13), a variable gain amplifier(25), and a CPU(24). The CPU obtains calibrating information based on a voltage value outputted from the variable gain amplifier to calibrate an inverter sensing value. An amplification gain is changed into a desired value in the variable gain amplifier by a control signal.
