Abstract
A method for preventing a discharging of a battery is provided. In particular, the method prevents a discharging of a battery by adjusting a relay turn-off voltage of the battery based on a voltage drop speed of the battery. The method includes measuring a battery voltage after a turn-off of an ignition of a vehicle, calculating a voltage drop speed from the measured battery voltage, and comparing a storing and leaving interval of the battery that corresponds to the voltage drop speed with a set storing and leaving interval. When the storing and leaving interval of the battery is less than the set storing and leaving interval calculating a relay turn-off voltage is calculated and when the relay turn-off voltage is equal to the battery voltage, a relay is turned off.
