Yuan Wei and Xu Huixiong, analysts at Anxin Securities, also released a research report recently, saying that the conditions for mass production of high-voltage platform models are basically mature: from the point of view of parts, the industrial chain of high-voltage parts at the end of the car and pile is gradually improved. among them, the main parts of the
A ″1 to N″ automatic charging pile is proposed, which enables a single automatic charging pile to provide self-consistent charging and energy replenishment services for multiple vehicles to be charged, greatly improving the time and space utilization efficiency of charging piles. At the same time, in the "1 to N″ system, only a single vehicle is charging at the
The rise in the number of electric vehicles used by the consumers is shaping the future for a cleaner and energy-efficient transport electrification. The commercial success of electric vehicles (EVs) relies heavily on the presence of high-efficiency charging stations. This article reviews the design and evaluation of different AC/DC converter topologies of the
Charging of New Energy Vehicles With the phase-out of fiscal and tax subsidies for new energy vehicles, as well as the transition of national and local policies from "vehicle subsidy" to "use subsidy", governments, including central governments and local governments, work hand in hand to establish a good and stable industrial environment for charging facilities. By the end of
The New Energy Automobile Industry Development Plan (2021–2035) issued by the Ministry of Industry and Information Technology of the People''s Republic of China in 2020 points out that the gap of charging piles in China reaches 63 million, which seriously does not match the development speed of new energy vehicles and requires investment and
The energy storage capacity of energy storage charging piles is affected by the charging and discharging of EVs and the demand for peak shaving, resulting in a higher installed capacity. Comparative analysis shows that with the increase in the proportion of EVs
According to the International Energy Agency report, by 2030, and takes uncertain factors into account in the evaluation index of location and capacity, which provides a new idea for EVs charging pile planning. According to the taxi trajectory and the photovoltaic output characteristics in the power grid, Reference Shan et al. (Citation 2019) realized the
The forecast results show that in 2025, the ratio of NEVs to public charging piles will rise to 10.2:1 and the ratio to private charging piles will fall to 2.5:1. The overall ratio shows
In this article, a real-time fault prediction method combining cost-sensitive logistic regression (CS-LR) and cost-sensitive support vector machine classification (CS-SVM) is proposed. CS-LR is first used to classify the fault data of smart charging piles, then the CS-SVM is adopted to predict the faults based on the classified data.
