Storage Battery is a device that directly converts chemical energy into electrical energy. It refers to a battery that can be used to activate active materials by charging after the battery is discharged. After a chemical reaction is converted into electrical energy, electrical energy can also be used to repair the chemical system, and then the chemical reaction can be converted into electrical energy. The battery usually refers to a lead-acid battery.

The battery box is an appliance used to hold the battery, and should have the properties of stability, waterproof, and easy heat dissipation. Electric bicycles are commonly used travel tools and one of the main installation carriers for battery boxes. In rainy days or when driving over deep roads with water, electric bicycles and bicycles are prone to water. Since the battery box of an electric vehicle is usually provided with vent holes to ensure heat dissipation performance, these vent holes are likely to become channels for rainwater to enter, thereby affecting the performance and service life of the battery. Generally, the vent is provided on the bottom or side of the battery box. When the vent hole is provided at the bottom, the accumulated water in the electric bicycle can easily enter the battery box; when the vent hole is provided on the side, rainwater flowing from top to bottom along the battery box can easily flow into the battery box from the vent hole.
