As the energy supply device of electric vehicle, the charging performance of electric vehicle charging post is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are most concerned about before buying electric vehicles. It is the basic principle for the design of electric vehicle charger to realize fast, efficient, safe and reasonable power supply for the power battery. In addition, the applicability of the charger to various power batteries should also be considered. The control system of the fast charger consists of: the control system of the fast charger adopts an intelligent variable pulse charging mode, that is, charging current pulse, including charging pulse T1, intermittent pulse T2 and discharge pulse T3.

According to the new national standard, the charging plug standard of different models in the future is the same. Xu Xinchao said, "Although there will be differences in voltage and power, theoretically it can be used in the same charging point. In addition, the new national standard attaches particular importance to the safety of the charging pile, which has always been the top priority. The standardized charging pile of new energy vehicles will automatically cut off power after charging, making breakthroughs in insulation and avoiding electric shock in rainy days, so as to avoid unnecessary dangers for new energy owners during charging. ".

Why does the new energy vehicle suddenly "break the circle" and make many consumers "turn into fans"? Compared with traditional fuel vehicles, what are the unique attractions of new energy vehicles for consumers? What are the characteristics and differences in products, marketing and services of different automobile enterprises? With these hot topics in mind, the reporter recently selected three enterprises in the high-end field of new energy vehicles, namely Tesla, Weilai and BYD New Energy stores in Beijing for experiential interviews to observe the changes of new energy vehicles in product power, price, marketing and service from the perspective of consumers. I hope to read with readers the reasons behind the unexpected growth of the new energy vehicle industry in the middle and high-end field, which is the "race track" of new energy vehicles.

The function of the charging post is similar to that of the gas dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. Generally, the charging pile provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to print the corresponding charging method, charging time, cost data and other operations. The charging pile display screen can display the charging amount, cost, charging time and other data.

A foreign technology company has given a perfect solution: the solar cone they developed is composed of thousands of triangular solar panels. With a specially designed condenser and rotating cone, they can obtain 20 times more light than before, while maintaining the temperature of the core conversion components within a safe range, greatly improving the energy conversion efficiency. Industry insiders believe that this innovation has practical operational significance for photovoltaic power generation, but large-scale popularization still needs to consider the cost and further technical improvement. In order to popularize the application in any industry, it is essential to continuously reduce the cost. Photovoltaic power generation was once very expensive, but driven by economies of scale, the cost of photovoltaic power generation has been declining in recent years, and now it is very close to parity. All this depends on the continuous innovation of photovoltaic technology.
