Battery pack for new energy automobile

Abstract

The invention discloses a battery pack for a new energy automobile. The battery pack comprises a heating rod, a cooling box, a water pump, a water outlet pipe, an exhaust pipe, a sucking pump, a box cover, a PCB, a box body, an explosion-proof layer, a rubber base, a supporting block, a partition plate, a battery body, a cavity, a shell, a temperature sensor, an inserting plate, a water adding port, a water inlet pipe, a first semiconductor chilling plate, a top cover, an air inlet pipe, a condensing box, second semiconductor chilling plate, a tinfoil layer, and a shell door. The shell of thebattery pack is provided with the cavity, the top surface of the shell is provided with the cooling box and the water pump, the water pump can be started in summer, and water in the cooling box circularly flows in the cavity under the action of the water pump, so the spontaneous combustion of the battery due to higher temperature in summer is greatly reduced, and the service life of the battery isgreatly prolonged; when the battery burns accidentally to generate explosion, the explosion-proof layer can effectively reduce the explosion range of the battery, and effectively reduce the harm generated during the explosion of the battery.

Description

Technical field[0001]The invention relates to a battery pack, in particular to a battery pack for a new energy automobile, belonging to the technical field of new energy automobile parts application.Background technique[0002]New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. Including pure electric vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., their exhaust emissions are relatively low, pollution is less, and they are increasingly affected. The favorite of the public, the pure electric vehicle is a kind of car that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source. The battery provides electrical energy to the motor and drives the motor to run, thereby driving the car. The battery pack is The heart of pure electric vehicles provides medium power for pure electric vehicles.[0003]However, the existing battery packs for pure electric vehicles mostly use...

Problems solved by technology

[0003] However, the existing battery packs for pure electric vehicles mostly use shells to simply cover multiple battery bodies, which has a poor cooling effect and is prone to leakage. In summer, the batteries are prone to overheating and spontaneous combustion. In addition, most of the existing battery packs for pure electric vehicles do not have the function of explosion-proof, and there are potential safety hazards. In winter, due to the low temperature, the operating temperature of the battery is low and the loss is large, which greatly reduces the pure The cruising range of electric vehicles is not conducive to the use of pure electric vehicles
