Which car
charging pile manufacturer ranks better? How to choose the brand of charging pile? Ranking of Top 10 Charging Pile Brands Shenzhen Hongjiali New Energy Co., Ltd. provides a ranking of the top ten charging pile brands. It is easy to understand which brand of charging pile is good and which product is good. New energy vehicles are the general direction of the development of the automotive industry. However, for new energy vehicles, the current problems are not performance, price, brand issues, but cruising range and charging issues. If the charging problem is not solved, the development of new energy vehicles will Subject to great constraints.
At present, the total number of automobile charging pile manufacturers exceeds 300, and the entire industry is in a period of rapid development, especially with the planned absolute capacity of 5 million in 2020. The overall development trend of the automobile charging pile industry is good.
In recent years, the market is still in the early stages of development. Whether it is new construction or renovation, and the diversity of participants, there are still many uncertainties in the future of the automotive charging pile industry.
