"Just like a large number of vehicles with different displacement currently coexist, with the increasing number of electric vehicles and the different consumption ability of different groups, there will be the coexistence of large, medium and small charging power in the future. This gives the government a big problem in planning charging facilities: how to layout the geographical space? How is the charging power distributed? " Xiao Xia, chairman of Shenzhen aotexun Power Equipment Co., Ltd., a leading enterprise of China's electric vehicle charging facilities, raised the above problems at the 2018 annual working conference of China charging alliance. In Xiao Xia's view, the current development of electric vehicle charging facilities is facing a serious bottleneck: structural supply imbalance. According to the calculation of China charging alliance, there are about 1.729 million new energy vehicles in China, including nearly 1.5 million pure electric vehicles and 801000 pure electric passenger vehicles. According to this data, the vehicle pile ratio of pure electric passenger cars has reached 1.8:1. "Nevertheless, there are still a lot of charging power mismatches. It is difficult to find a power matching charging pile for high-power electric vehicles, and the charging efficiency is low; sometimes, low-power vehicles will charge at the high-power charging piles, resulting in power waste. Moreover, in some places, the supply of charging facilities is in short supply, and electric vehicles are queuing up for charging; in some places, the supply of charging facilities exceeds the demand, resulting in extremely low utilization rate. " Xiao Xia said. Xiao Xia believes that the key to the construction of electric vehicle charging facilities is to have a forward-looking overall planning, but this planning is difficult to do, mainly because of the rapid changes in battery technology. Although we all agree that high-power charging is the mainstream trend in the future, no one can be sure when it will come. In addition, limited by the cost of batteries and the final sales price transmitted to consumers, there will be coexistence of large, medium and small power electric vehicles in the future, because the price of small power is low, and the price of high power is high. This proportion will have an important impact on the planning, and it is also impossible to predict. In her communication with many local governments, Xiao Xia also found that this problem is becoming more and more obvious. "Some places have made overall planning, but they find that before the investment in charging facilities is recovered, they are in an awkward situation because of the upgrading of battery technology: they are reluctant to be demolished and rebuilt, and they can't meet most of the needs if they continue to use them." "A few years ago, otsun foresaw this pain point, and the organization independently developed the matrix flexible charging stack technology." Xiao Xia said, "the integration of all or part of the intelligent charging modules in the electric vehicle charging station can automatically distribute the charging power according to the vehicle demand, which breaks through the problem of power solidification of the existing charging infrastructure, greatly improves the utilization rate of charging power and equipment, and enables the planning and construction of urban charging infrastructure."       &#16...
