Development Trend of New Energy EV Charging Stations
The Future Development Direction of New Energy EV Charging Stations With the gradual promotion and industrialization of electric vehicles and the increasing development of electric vehicle technology, the technical requirements of electric vehicles for charging piles reflect a consistent trend, and it is necessary to achieve "scenario-based, shared, networked, and intelligent". Zhuhai PIWIN New Energy Co., Ltd. is a new energy supporting enterprise dedicated to the construction of centralized charging stations for new energy vehicles, the construction of integrated optical storage and charging stations, electric pile sales and station operation services. The EV charging charger is required to be as close as possible to the following goals: Faster Charging At present, in order to shorten the charging time, the industry has begun to study the layout to upgrade the charging voltage of passenger cars from 500V to 800V, and the single-gun charging power can be increased from 120kW to 350kW and above. High-power DC charging technology. This also means that the time for a fully electric passenger car to be fully charged can be shortened from about 1 hour to 10-15 minutes. Universal Charging Under the market background of the coexistence of various types of batteries and various voltage levels, the charging device used in public places must have the ability to adapt to various types of battery systems and various voltage levels. The charging control algorithm of various types of batteries can match the charging characteristics of different battery systems on various types of electric vehicles, and can charge different batteries. Intelligent Charging One of the most critical issues restricting the development and popularization of electric vehicles is the performance and application level of energy storage batteries. The goal of optimizing the battery intelligent charging method is to realize the non-destructive charging of the battery, monitor the discharge state of the battery, and avoid the over-discharge phenomenon, so as to achieve the purpose of prolonging the service life of the battery and saving energy. Efficient Power Conversion The energy consumption indicators of electric vehicles are closely related to their operating energy costs. Reducing the operating energy consumption of electric vehicles and improving their economy is one of the key factors to promote the industrialization of electric vehicles. For the charging station, considering the power conversion efficiency and construction cost, the charging device with many advantages such as high power conversion efficiency and low construction cost should be preferentially selected. Charging Integration In line with the requirements of subsystem miniaturization and multi-function, and the improvement of battery reliability and stability requirements, the charging system will be integrated with the electric vehicle energy management system as a whole, integrating pass transistors, current detection and reverse discharge protection, etc. It can realize a smaller and more integrated charging solution without external components, thus saving the layout space for the rest of the electric vehicle components, greatly reducing the system cost, optimizing the charging effect and prolonging the battery life. In the future, the country will urgently promote the development of new energy vehicles. With the growth of the number of new energy vehicles in my country in the future, the demand for charging piles will further expand.
