A doubling style increment
During the 2026 National Day holiday, highway service areas added more than 11,000 high power charging units, equal to the entire cumulative total before the holiday. This directly answers the peak season queue pain and shows highway scenes favor plug and go high power DC charging for travelers.
The technology behind one kilometer per second
All liquid cooled stations in Hunan and Henan reach 600 kW per gun with a refill speed near one kilometer per second, built on liquid cooling and high voltage platforms. Back in communities, residents still rely on stable low cost 7 kW slow charging, so the two scenes complement rather than replace each other.
Fast on highway, stable at home
Highways can be fast, but communities must be stable. Dongshang New Energy and Dongdian Huichong keep 7 kW slow and orderly charging in Yantai neighborhoods with routine patrols, so residents charge downstairs and get repairs when needed, holding both speed and safety together.
