[0002] The pure electric vehicle in the new energy vehicle, its energy comes entirely from the battery, but the battery is prone to heat during use, especially when charging, if the charging pile is abnormal, the battery heat will be too high and the battery will be damaged or even burn and explode. The battery protection mainly depends on the control center on the car, but when the car is parked and charged, the car is powered off, and the control center cannot protect the battery charging process well. It is likely to cause heat explosion due to short circuit, resulting in safety accidents

The invention relates to the related field of new energy automobiles, and discloses a new energy automobile battery protection device which comprises a main box body, a battery protection cavity is formed in the main box body, a ventilation cavity with an upward opening is formed in the upper side of the battery protection cavity in a communicating mode, and a sliding rod cavity is formed in the lower side of the battery protection cavity in a communicating mode; and a fan seat is rotatably connected with the inner wall of the ventilation cavity; when an automobile runs, power of the automobile is used for driving the fan to rotate, so that a battery is cooled, and when the automobile stops charging, if the battery emits heat, a heat dissipation motor is automatically started to drive thefan to rotate, so that the battery is cooled, meanwhile, the charging current is reduced, and the battery is prevented from burning and exploding due to over-high heat emission; and according to the battery temperature feedback, the higher the temperature is, the faster the rotating speed of the fan is, and the smaller the charging current is, so that the charging safety of the new energy automobile is ensured, and meanwhile, a plurality of buffer springs are arranged in the battery protection cavity, so that combustion explosion caused by serious battery deformation is avoided when the automobile is suddenly impacted.
Description
technical field [0001] The invention relates to the related fields of new energy vehicles, in particular to a new energy vehicle battery protection device. Background technique [0002] The pure electric vehicle in the new energy vehicle, its energy comes entirely from the battery, but the battery is prone to heat during use, especially when charging, if the charging pile is abnormal, the battery heat will be too high and the battery will be damaged or even burn and explode. The battery protection mainly depends on the control center on the car, but when the car is parked and charged, the car is powered off, and the control center cannot protect the battery charging process well. It is likely to cause heat explosion due to short circuit, thus causing safety accidents. Contents of the invention [0003] The purpose of the present invention is to provide a new energy vehicle battery protection device, which can overcome the above-mentioned defects of the prior art, thereby ...
