Building a High-Quality and Sustainable EV Charging Network

This article, authored by Jia Junguo, Chief Expert at the China Energy Research Society, explores the development of a high-quality and sustainable charging network for electric vehicles. It examines seven key dimensions affecting the charging industry, focusing on fast-charging battery advancements and the emergence of ultra-fast charging vehicles. Battery technology is rapidly evolving, with solid-state batteries and new power battery products from companies like CATL, BYD, and EVE Energy achieving higher energy densities and faster charging rates, such as 12C charging enabling 520 km in 15 minutes. However, battery cost and weight constrain large-scale adoption. High-voltage platforms, particularly 800V systems, are becoming standard for high-end models, with charging power demands exceeding 360 kW. User habits vary, but convenience and speed remain fundamental choices. Currently, low-power public charging piles (below 60 kW) dominate the market at 58.9%, while high-power segments (≥240 kW) are still nascent. The article questions whether ultra-fast charging alone can support tens of millions of electric vehicles, emphasizing the need for a balanced ecosystem.
