On board charging device refers to the device installed on the electric vehicle that uses the ground AC power grid and the on-board power supply to charge the battery pack, including the on-board charger (Figure 1-13), the on-board charging generator set and the operating energy recovery charging device. A AC power cable with a plug is directly inserted into the charging socket of the electric vehicle to charge the battery. On board charging devices usually use contact chargers with simple structure and convenient control, or inductive chargers. It is designed completely according to the type of on-board battery, with strong pertinence. Off board charging device, i.e. ground charging device, mainly includes special charger, special charging station, general charger, charging station for public places (Figure 1-14), etc. It can meet various charging modes of various batteries. Generally, the off board charger has large power, volume and weight to adapt to various charging modes.

As a green means of transportation with broad development prospects, the popularization of electric vehicles will be extremely rapid in the future, and the future market prospect is also extremely huge. In the context of the global energy crisis and serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the charging/changing station has very important social and economic benefits. A campaign to build an electric vehicle charging/changing station has been launched nationwide. The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.

Not only does China attach importance to the development of new energy charging equipment, foreign new energy companies are developing more rapidly, and French oil giant Total is also actively building charging equipment. In the early years, Total acquired Saft, a battery manufacturer. This company originally produced power batteries and provided automotive batteries for many automobile manufacturers. And some foreign companies have even developed wireless charging technology. They transmit wireless energy through magnetic induction between the charging coil and the receiver. The charging coil is buried under the ground. When it needs to be charged, just drive the car to an appropriate position to charge. New energy vehicles are very popular in recent years. Because of the environmental protection of new energy vehicles, many countries advocate new energy vehicles, and many people are interested in new energy vehicles. The New Energy Vehicle Technology Analysis has relevant content. Obviously, the trend of fuel vehicles has gone.

How to make money by investing in charging piles? In recent years, the investment in charging piles has become more and more popular. As of July 2021, the number of public charging posts nationwide will be 950000, a high growth of 67.85% year on year, and the charging power will increase by 44% year on year. So, is this the right time for operators who are investigating the charging pile market or preparing to invest in construction? The answer is yes. Under the background of "dual carbon", the new energy vehicle market is a huge market with continuous growth, belongs to the blue ocean market, and is rigid demand. The investment threshold is relatively low compared with gas stations. Since the market is so good, why can't many charging stations make money? At present, the main profit sources of charging piles are service fees, power price difference and value-added services.
