The invention discloses a method and a system for preventing over-charging and over-discharging of a battery based on an automobile motor. The method comprises the following steps: acquiring currently available maximum charging and discharging power of the battery and preset data of the motor in real time; calculating a torque value according to the maximum charging and discharging power and the corresponding operation efficiency and rotating speed; and adjusting the torque output of the motor according to the torque value. The problem that the battery is overcharged and overdischarged when the power of the motor is unbalanced is solved, the torque of the motor is controlled, the battery is prevented from being overcharged and overdischarged, and the service life of the battery is prolonged.
