In addition, according to the different ways of energy conversion when charging the electric vehicle battery, charging devices can be divided into contact type and induction type. With the rapid development of power electronics technology and converter control technology, the maturity and popularization of high-precision controllable converter technology, the phased constant current charging mode has been basically replaced by the constant voltage current limiting charging mode with continuous changes in charging current and charging voltage. The constant voltage current limiting charging mode dominates the charging process. The big problem of contact charging is its safety and versatility. In order to make it meet the strict safety charging standard, many measures must be taken in the circuit to enable the charging equipment to charge safely in various environments. Constant voltage current limiting charging and phased constant current charging are both contact charging technologies. New induction charging technology for electric vehicles has developed rapidly.

Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.

Safety requirements (1) The substation shall be equipped with safety bulletin board, warning board, safety signal light and alarm bell. (2) The warning sign of "Stop, High Voltage Danger" shall be hung outside the door of the high-voltage distribution room and transformer room or on the safety column of the substation. The warning signs must face the outside of the fence. (3) There shall be obvious operation instructions on the high-voltage distribution device. The grounding point of the equipment shall have obvious signs. (4) There should be obvious signs of "safe passage" or "emergency exit" in the room. In addition, the layout design of substation and distribution equipment shall facilitate installation, operation, handling, maintenance, test and monitoring. High and low voltage distribution room, transformer room, capacitor room and control room should not have unrelated pipes and lines passing through. New energy vehicles should first focus on cities, but the busy IX region is often short of land, and the cost of land is high. In this regard, the government needs to give preferential policies to promote the construction of charging facilities. The development and operation of electric vehicle charging stations by electric power enterprises have inherent advantages.

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.

What should be paid attention to when charging electric vehicle batteries? When the electric vehicle starts and goes uphill, it is necessary to avoid emergency braking and acceleration as much as possible, because large current discharge will be formed during this process, which will damage the performance of the battery. There are also two points that need special attention when stopping for a long time. 1. Parking without power supply should be avoided: unlike traditional gasoline vehicles, electric vehicles have their own "unique taste" for the state of vehicle parking. If the "hungry stomach" is used too long, it will "rebel". When the electric vehicle is parked in the case of power loss, the battery is prone to sulfation, blocking the electric ion channel, resulting in insufficient charging and declining battery capacity. 2. Deep discharge shall be carried out regularly: when the electric vehicle is almost out of power, undervoltage protection will automatically occur, but during this process, its voltage is unstable, and it will also be up and down, causing repeated undervoltage protection status
