Quality inspection of AC charging pile for electric vehicle
Charging and improving charger performance is the key to management. What are the advantages of the electric vehicle charging pile? There are several charging piles. Since the birth of the fast and environmentally friendly electric vehicle, it has been favored by the public, but the charging difficulty has troubled the "electric vehicle family". Electric vehicle charging pile is mainly composed of charging motor, charging module, metering module and charging gun. It has the functions of electric energy measurement, billing, communication monitoring, etc. the charging motor and charging module are the main parts of electric vehicle charging pile, and they are important components of charging quality of electric vehicle charging pile. Their cost is not high, accounting for about half of the total charging cost. Individual overload measurement barcodes can only be written in digital English, about 18 bytes, which can only be recorded in one way, and can be translated into Chinese, just like commodity code, it can record the place of origin, production date, manufacturer, etc. When the charging rate is less than C / 100, the capacity of the battery can be restored to 100%, which shows the response of overcharge. Charging enterprises also need to increase the research and development of fast charging technology, and create a higher charging speed on the premise of not losing or shortening the life of the battery, so as to create their own barriers. The function of the charging pile is similar to that of the filling device inside the gas station. It can be fixed on the ground or on the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels.
Some traditional charging shed is installed by the company. In order to make profits, the company will charge higher fees to the users of the traditional charging shed. Because the power of electric vehicle charging motor is generally small, AC charging pile realizes fast charging, so AC charging pile is also called slow charging. The input end of charging pile is directly connected with AC power grid, and the output end is equipped with charging plug for charging electric vehicle. To restore battery capacity to 100%, some overcharge reactions must be allowed. From the current market situation, although the charging pile has broad development prospects, but due to the problems of nonstandard operation and difficult cost reduction, the industry has not entered the "profitable" track. There are signs on the charging point to store the link address of background program of charging management application software of electric vehicle. It has overload and under load functions. In China, the construction of electric vehicle charging station is still relatively small, most of the electric vehicle charging piles are scattered in various parking lots or charging stations or buildings.
In addition to the same safety performance as the intelligent charging pile, the charging box of electric vehicles can also be used outdoors, rain proof and lightning protection. In order to prevent fire caused by high temperature during charging, each charging box is equipped with smoke alarm device and dry powder fire extinguisher, which makes the charging of electric vehicles safer. When the rated power is large, the power supply will be cut off automatically. The charging station receives the discharged battery, and then customizes the charging scheme in the stages of fast charging, normal charging and trickle charging. The output power of AC charging pile is not large, generally 5 kW, 7 kW, 15 kW and so on. Although the construction speed of energy vehicle charging pile is very fast, it also meets and supports the increasing charging demand and charging mileage of electric vehicles. In order to facilitate the property management of electric vehicle charging, electric vehicle owners can easily and timely charge. The electric vehicle charging station has been developed and rapidly rising. But there is a device called electric vehicle charging pile on the streets of this country, which brings great convenience to people's electric vehicle travel. There are two main charging methods: ordinary charging and fast charging. People can swipe the card on the human-computer interaction interface by using the special charging pile charging card to realize the corresponding charging mode, charging time, charging data printing and other operations. The charging pile screen can display the charging amount, charging data, charging time and other data.
