PURPOSE: Residual electricity management system and method for an electric vehicle is provided to offer the optimum charging condition for the vehicle by using information of the residual electricity quantity of a charger and the transport condition. CONSTITUTION: A residual electricity management system for an electric vehicle includes a voltage data extracting unit(110), a speed data extracting unit(120), a vehicle environment information inputting unit(130), a driving data collecting unit(210), a residual electricity data calculating unit(220), a drivable distance calculating unit(250), and a data outputting unit(400). The voltage data extracting unit collects battery voltage data from the engine of the electric vehicle. The driving data collecting unit continuously collects voltage change and speed change information. The residual electricity data calculating unit calculates residual electricity data by using a residual electricity graph database(230).
