Three-wheeled electric vehicle is a kind of three-wheeled transport vehicle which uses battery as power and motor as driving force to pull goods or people. Three-wheeled electric vehicles are divided into household type, freight type and factory type according to their uses.

Three-wheeled electric vehicle adopts large-capacity tubular battery, left and right lining, deep discharge and traction type, which can meet the requirements of continuous discharge after long-term work. The battery has been used normally for two years, and its content has not decreased. The motor of three-wheeled electric vehicle adopts DC series excitation traction brush or brushless motor, and the motor has built-in speed regulating and force increasing device, which is not easy to be damaged during normal use and ensures strong output power.

As an important energy source with environmental protection, cleanliness and high conversion rate, electric power is widely used in production and life. It is used to drive the upgrading of vehicles, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy and protect the environment. After decades of development, it has been applied to the construction of electric city buses, electric transport vehicles in factories and mines, electric city sanitation cleaning vehicles, projects, tunnels and subways.
