Description

A double-socket bottom cover for a battery

Technical Field

The utility model belongs to the technical field of battery charging, and in particular relates to a double-socket bottom cover for a battery.

Background Art

Traditional motorcycles usually use gasoline as fuel, but the large-scale use of gasoline brings about a series of environmental pollution problems such as global warming. In addition, gasoline is extracted from petroleum and is a secondary energy source, which belongs to non-renewable energy. In order to protect the environment and save resources, major companies are competing to develop electric motorcycles, which use electricity as energy and convert electrical energy into mechanical energy through electric motors. As long as the battery of the electric motorcycle is charged on time, the electric motorcycle can be used continuously, saving energy and improving environmental quality. However, in the market, batteries usually use direct battery plug-in type, but the existing sockets usually only have one three-phase socket, which leads to a large current in a single branch during the charging process, a fast temperature rise rate, and the safety of the charging process cannot be guaranteed.
