Abstract
A method for preventing over discharge of a battery includes steps of: detecting a gradient of a road on which a vehicle is running by a controller, when a battery is discharged under a state that an engine of the running vehicle is operated, detecting a clutch driving state of an engine clutch, which connects or disconnects the engine and an electric motor, after detecting the road gradient, detecting a SOC (State of Charge) of the battery after detecting the clutch driving state of the engine clutch, and carrying out a torque reserve control allowing more torque to be reserved in the engine, using a combination of the road gradient, the clutch driving state, and the battery SOC, such that the battery SOC is not lowered below a certain amount.
