A multi-input charging system and method using a motor driving device: the system includes a first inverter including a plurality of first switching elements, a second inverter including a plurality of second switching elements, a battery connected to a charging power input terminal or one end of the second inverter through a charging switch, and a controller configured to directly charge the battery through the charging power input terminal by selectively connecting the charging switch when a battery charging mode is started, and when connection of the charging switch is impossible, control the first switching elements and the second switching elements such that the charging power input terminal and the battery are connected through the first inverter, a motor, and the second inverter in a bypass manner.

Disclosed is a system and method for computing distance to empty (DTE) based on available energy computed using a battery SOC vs open circuit voltage (OCV) table, battery temperature vs energy efficiency, an energy efficiency vs energy table, etc., to enable a more accurate calculation of the DTE in consideration of the temperature of the battery, which is one of disturbance elements.
