DC type: a) Power input voltage of charging pile (plug): three-phase four wire 380VAC ± 15%, frequency 50Hz ± 5%; b) The charging pile (plug) shall meet the charging object; c) The output of the charging pile (plug) is DC, and the output voltage meets the battery system requirements of the charging object; d) Zui's large output current meets the charging requirements of battery system 1C of the charging object, and is downward compatible; e) The charging mode can be divided into conventional and fast charging modes. The conventional charging mode is 5-hour charging mode, and the fast charging mode is 1-hour charging mode (selected for different battery types); f) Realize intelligent IC management; g) Each charging pile (plug) is equipped with an operator for the user to select charging mode and guide operation, and display the battery status of electric vehicles and the user's IC card charge information to achieve unattended management;

With the gradual maturity of the entire new energy vehicle industry chain and the gradual release of market demand, the industry is about to erupt in 2018, but the problems of insufficient structural supply of charging infrastructure and the overall scale lag are increasingly prominent. It is urgent to make up for shortcomings and accelerate the construction of supporting infrastructure such as charging piles. How can we solve the problem of insufficient structural supply of charging infrastructure? Is there any successful case of innovative practice worth learning? There is a big gap in the charging pile. Under the global environment of resource conservation and green economy development, new energy vehicles are developing very rapidly. As the power guarantee of new energy vehicles, the charging pile is highly concerned by all circles. It can be said that the construction of charging infrastructure is one of the key factors affecting the promotion of new energy vehicles in China, and is more related to the development prospects of new energy vehicles.

When the charging post is built, it should be used and managed well. The implementation of management responsibility and clear operation mode can make the charging pile safe and reliable. At present, the charging pile is faced with the problem of unclear management responsibility and unclear operation mode. There are some problems such as the aging of distribution facilities in the community, who will pay for the reconstruction, the quality of piles is mixed, and who will solve the hidden fire hazards. The same is true of public charging posts. There are not many DC fast charging piles with high investment standards and high power, but "problem piles" and "zombie piles" are common. In recent years, the number of charging pile construction and operators in China has grown rapidly, but the level of enterprises is uneven.

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
