As the global penetration rate of new energy vehicles (NEVs) rises, the US and European markets are shifting from subsidy-driven to charging facility construction, but the lagging charging network has become the core bottleneck of industrial development. In the United States, the ratio of cars to charging piles will reach 17:1 in 2022, far exceeding the reasonable level. The goal of 500,000 public charging piles is considered insufficient. The market size is expected to expand to US$19.1 billion at a compound growth rate of 80% in the next three years. The US government has passed the National Electric Vehicle Infrastructure Plan (NEVI), which requires federal funding for local production of charging piles, with the goal of more than 55% of the local industry chain in 2024. In Europe, BEV sales increased 18 times from 2016 to 2022, while charging piles only increased 6 times. The imbalance between cars and charging piles has led to poor consumer experience. Although the EU has proposed a goal of banning the sale of fuel vehicles in 2035, the convenience of charging still needs to be improved. The IEA predicts that the number of NEVs in the EU will reach 21.9 million in 2025, and the demand for charging piles is expected to increase from 5 billion euros to 15 billion euros.
