テリ保護装置。[Scope of Claim for Utility Model Registration] (1) In a vehicle that is equipped with an electric motor for driving on-vehicle equipment and supplies power to the electric motor from an on-board battery, a voltage detection means for detecting the battery voltage of the on-board battery; and the voltage detection means. a first determining means for determining whether or not the battery voltage detected by the voltage detecting means is less than or equal to a first predetermined value; and a second predetermined value for which the battery voltage detected by the voltage detecting means is greater than the first predetermined value. a second determination means for determining whether or not the battery voltage exceeds the first determination means;
When the battery voltage is determined to be below a predetermined value, the power supply to the electric motor is stopped, and when the battery voltage is determined by the second determination means to be above a second predetermined value, the power supply to the electric motor is resumed. A battery protection device for a vehicle, comprising: means. (2) The power supply limiting means stops power supply to the electric motor when the battery voltage remains below a first predetermined value for a predetermined period of time. Protective device. (3) The battery protection device for a vehicle according to claim 1, wherein the power supply limiting means gradually reduces the current flowing to the electric motor when stopping power supply to the electric motor. (4) The power supply limiting means resumes power supply to the electric motor when the battery voltage exceeds a second predetermined value for a predetermined period of time. Protective device. (5) The battery protection device for a vehicle according to claim 1, wherein the power supply limiting means gradually increases the current supplied to the electric motor when restarting power supply to the electric motor.
