Quantity of Public Charging Piles in China, US, and Europe to Determine Changes in Global Car-Pile Ratio
China's public charging piles account for about 60% of the global charging market in quantity, though domestic market competitions are comparatively severe, and that these charging piles are excessively concentrated in coastal regions. The US is slower in deployment of public charging piles, while countries in Europe are also exhibiting a larger differentiation in efficiency. Despite clear deployment targets among China, Europe, and the US, a continuous observation on whether the level of efficiency conforms to expectations is essential in ensuring the reduction of global car-pile ratio each year.
