电动汽车一体化充电机在空闲状态下进行充电模块自检，当某一模块存在可控状态下的报警时，依然可以进行正常的充电流程，监控系统可将故障信息发送到后台，以便进行维护处理。 当电动汽车需要充电时，用户将充电卡放置刷卡区，根据画面提示通过键盘进行相应操作，连接充电接口，选择充电模式，启动充电过程。在上述过程中，总控单元检测充电接口连接状态，如果连接状态不正常，则无法启动充电。同时，在充电过程中，显示区的充电指示灯点亮。总控单元实时监测充电电压、充电电流、充电接口连接状态、充电开关状态等，在异常或故障时断开 充电开关，并报警。
With the increasingly stringent environmental requirements and the rapid development of new materials and technologies, the development of electric vehicles has entered a climax. While developing and manufacturing electric vehicles, we must consider them in a forward-looking way.
Construction of related facilities for electric vehicles. Only by systematically constructing the relevant supporting facilities of electric vehicles can we provide strong support for the expansion of the electric vehicle market. In the relevant supporting facilities of electric vehicles, the construction of charging stations is extremely important. China's electric vehicle charging facilities pilot project has built several charging stations and tens of thousands of AC charging piles, covering many provinces and cities throughout the country. At present, there are two main ways for the construction of electric vehicle charging facilities. One is the charging station occupying a large site, and the two is a small space charging pile mode. All of these two ways have some shortcomings. The charging station can satisfy the current demand of direct current charging and AC charging. However, it is difficult to have suitable local construction in the increasingly tense urban space, and can only be located in the suburb of the city; and the discrete pile that occupies little space can only charge the electric vehicle with the vehicle charger.
A few days ago, the first Qinghai integrated electric vehicle charging station was built in Haibei Tibetan Autonomous Prefecture, West Sea town, integrated with many advanced technologies, such as photovoltaic power generation, intelligent charging pile, energy storage battery and so on.
It is understood that the light storage integrated electric vehicle charging station is the 2015 science and technology support plan project of the Qinghai provincial science and Technology Department, with a total investment of about 2 million yuan (RMB), which is a permanent charging station. Among them, the PV installed capacity is 35KW, the daily power generation capacity is about 200 degrees, the energy storage capacity is 150KWH, and the charging pile is 12. It can provide direct current charging and exchange slow charge service for all the mainstream brands of electric vehicles at home and abroad.
The charging station is equipped with a zinc bromine liquid energy storage battery, which breaks through the bottleneck that the photovoltaic power station can not charge for the electric vehicle at night, so that the electric vehicle is really used in the green and pollution-free energy power.
But the charge station occupies a large area, and the light storage equipment still has a lot of disadvantages in the areas of inadequate city and sunshine, and the cost is slightly higher. This is why the charging street lamps are very popular in the urban investment.
Conception of electric vehicle integrated charging station
On the basis of meeting the technical requirements of electric vehicle charging pile, the product will strengthen the electrical safety of the charger, the design of data safety and the design of the environment and electromagnetic compatibility. It has the functions of automatic rejection of the fault charging module and the wireless networking. The product is designed by modularization, which is beneficial to the maintenance of the product, at the same time reducing the use rate of space, making the whole space of the charging station smaller, saving the area and saving the cost of capital.
The electric vehicle integrated charger is self checked in the idle state. When a module has a controllable alarm, it can still carry on the normal charging process. The monitoring system can send the fault information to the backstage, so as to carry out the maintenance and processing. When the electric car needs to be recharged, the user puts the charge card into the card area, according to the screen prompting the corresponding operation through the keyboard, connecting the charging interface, selecting the charging mode and starting the charging process. In the above process, the total control unit detects the connection state of the charging interface, and if the connection state is not normal, it can not start charging. Meanwhile, during the charging process, the charging indicator light in the display area is lit. The total control unit monitors the charge voltage, the charging current, the connection state of the charging interface, the state of the charging switch and so on. The charging switch is disconnected and the alarm is disconnected in the case of abnormal or failure.
In the future, the market of charging equipment is very broad in China. The light storage charging station has already been put into use. So the future energy storage of wind energy and water power is not unimaginable.
