EV Watch 2Q23: Status of quick-charging techs

Range anxiety plays a pivotal role in influencing consumers' decision to purchase an electric vehicle (EV). A number of solutions have been proposed to address range anxiety including high-power quick-charging, increasing battery capacity installed on EVs and battery swapping.

DIGITIMES Research believes 800V high-voltage high-power quick-charging has four major advantages and features a charging efficiency closest to fueling a gasoline car so EV makers are growingly devoted to high-voltage quick-charging R&D.

Analyzing the roll-outs of public charging piles in the world's top-3 EV markets in 2022, China's vehicle-to-pile ratio ranked first while Europe and the US both have a ratio of above 10:1.
