METHOD AND SYSTEM FOR VERIFYING BATTERY VOLTAGE DETECTION OF ECO-FRIENDLY VEHICLES

In a method and system for verifying battery voltage detection in an eco-friendly vehicle, the method for verifying battery voltage detection in an eco-friendly vehicle includes the steps of determining whether abnormality has occurred in voltage detection based on a voltage of a first battery cell with a highest voltage among a plurality of battery cells forming a battery at a first time point when a limited discharge output of the battery decreases at or below a threshold power while the vehicle is running and a voltage of a second battery cell with a lowest voltage at the first time point, and recovering an output of the battery to a normal output that allows the vehicle to drive normally and driving the vehicle if it is determined that the abnormality has occurred in the voltage detection.
