Problems solved by technology
In order to pursue high energy density and long battery life, current electric vehicles reduce the thickness of the diaphragm in the battery, which poses a certain safety hazard to the battery safety and can easily cause thermal runaway.
In addition, the rapid adjustment of the subsidy policy is not coordinated with the development cycle of the power battery system, which leads to the inability of the product to be fully verified, which in turn creates potential safety hazards

The invention discloses a fireproof battery box for a new energy vehicle, which belongs to the technical field of new energy vehicles, and comprises a battery storage box and integrated fire extinguishing and heat dissipation devices arranged on both sides of the battery storage box. The opening where the integrated fire extinguishing and heat dissipation device is installed. During normal operation, the motor drives the blades to rotate, and the battery storage box is ventilated from the inside to the outside to dissipate heat. When the infrared flame detector detects a flame, the motor reverses and drives the valve at the same time. When it is turned on, the motor drives the blades to rotate in reverse, and the blades transfer the dry powder in the dry powder storage device to the battery storage box. The device of the invention can prevent the safety problems caused by the spontaneous combustion of the battery and ensure the safety of the battery and the whole vehicle.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a fireproof battery box for new energy vehicles. Background technique [0002] In 2018, new energy vehicles ushered in another round of explosive growth. According to official data from the China Automobile Association, the cumulative sales of new energy vehicles in 2018 exceeded one million units. But at the same time, behind the high growth also exposed a lot of security problems. The occurrence of many spontaneous combustion incidents has made the industry begin to examine the technical and quality issues behind the spontaneous combustion incidents. In order to pursue high energy density and high battery life, the current electric vehicles reduce the thickness of the separator in the battery, which poses a certain safety hazard to the safety of the battery, and it is easy to cause thermal runaway. In addition, the rapid adjustment of the subsidy poli...
