In response to the country's call for green, low-carbon and environmental protection, the electric vehicle industry has risen rapidly. Compared with ordinary cars, electric cars have the obvious advantage that they do not need to refuel and will not produce exhaust gas that affects the environment. With the introduction of electric vehicles, a series of products related to electric vehicles, such as charging guns and charging piles, are well known. The charging problem of electric vehicles is a key issue in the development of electric vehicles. Although there are various types such as AC charging piles, DC charging piles, wall-mounted charging piles, floor-mounted charging piles, column charging piles, and double-gun charging piles, The utilization rate is relatively low. The charging pile has different styles and cannot meet the charging problems of all types of electric vehicles at the same time, so there are some inconvenient factors. The new energy adapter is an important auxiliary charging device for electric vehicles, which can realize the connection charging problem between different models and standard electric vehicles and charging piles, and improve the convenience of charging. New energy adapters have two different modes: class structure mode and object structure mode. The new energy adapter is an interface converter, which can convert the interface into another interface. Insert the new energy adapter into the charging gun and connect it to the charging port of the electric vehicle to solve the charging problem of the electric vehicle. The adapter can also be an independent hardware interface device, allowing hardware or electronic interface, hardware and electronic interface to be connected. It can also be an information interface. New energy adapters are innovated in appearance design, structural design, and man-machine use, and are designed in strict accordance with national industry standards. The appearance design is simple and atmospheric, decorated with classic black. Considering people's hand-held habits, streamlined design is adopted, and concave design is adopted in the middle of the adapter to improve the comfort of hand-held. ABS PC matte material is selected, and the surface process is exquisite. The new energy adapter is simple to operate, and the surface is marked with various indicator lights. When a fault occurs, the corresponding indicator lights will light up and the label is very clear, bring more convenience to users.
