The battery box body is a container for installing energy storage batteries in an electric vehicle, and has functions such as protecting the battery, heat dissipation, and fire and explosion prevention. The main functions include preventing damage to the battery caused by external physical impacts and squeezes, ensuring the safe and stable operation of the battery; reducing the battery temperature through reasonable heat dissipation design to improve the working efficiency and service life of the battery; and designing for safety problems such as explosion and fire that may occur to the battery to ensure the safety of the battery during operation. The structure of the battery box body generally includes parts such as a box cover, a box body, and connecting parts. The material performance requirements are good flame retardancy, dimensional stability, corrosion resistance, and high strength. Currently, modified PPS, modified PP, or PPO and other materials are mainly used. During the use of the existing battery box for new energy vehicles, when there is a liquid leakage phenomenon in the battery, the surface of the battery box is easily contaminated and the leaked liquid spills out to contaminate other components. Therefore, the existing battery box for new energy vehicles does not have a liquid leakage collection function. For this reason, we propose a battery box for new energy vehicles.
