Problems solved by technology

[0004] However, the above-mentioned device can only issue an alarm when the temperature is too high, but cannot disconnect the power supply in time. If no one hears the alarm sound when charging, it will cause serious heat accumulation inside the power supply, and then greatly reduce the life of the battery. Spontaneous combustion may even cause a large amount of economic losses. When a short circuit occurs between the charger and the battery inside the car, the current generated by the short circuit will emit a lot of heat, causing serious damage to the charger and the battery. The generated current may also Leakage will cause damage to the owner, so a new energy vehicle power battery charging protection device is needed

Abstract

The present invention disclosed a new energy vehicle power battery charging protection device, including installing bases, driving motors, battery storage, charging plugs, and battery cells.There is a installation box through the screw fixing connection on the wall. The inner cooling cavity of the installation box is opened. There is a installation slot on the outer wall of the installation box.Drive motor fixed installation on the inner wall of the fixed box, which is fixed with a fan at the end of the output shaft of the drive motor. The battery is fixed inside the installation box.Sulfurization can play an insulation and protective effect, avoiding the continued discharge of the loan plug and the outside world, so as to achieve the rapid power off -power disconnection of leakage and short circuit phenomenon during the charging process of the new energy vehicle, and it does not need to be more secure and convenient to manually operate.
