From slogan to experience
'Plug in and charge, scan any home'—charging interconnectivity is turning from slogan into experience. In May 2026 the China Charging Alliance with CEC released the V2.0 high-power charging interoperability spec: new ultra-stations and 800V models must adapt by 31 Dec 2026, stock equipment by end-Jun 2027 via software. TELD, StarCharge, State Grid, Huawei and Xiaoju among eight top operators adapted first, covering ~85% of ultra terminals, sharply narrowing the 'your app can't charge my stall' split.
One network forms
A 'single network' is also taking shape on the platform side. The national charging interconnect platform passed 1 million piles in Sep 2026—about 42% of public piles, ~680 operators, clearing cut to T+7; after the 20 Mar unified interface (7-hole AC, 9-hole DC), over 90% of public terminals adapted. The most visible change for users: cross-operator charging steps down ~60% and satisfaction up 8 points—no more downloading a different app and rebinding cards for every stall.
Yantai: fewer apps
For Yantai owners, interconnectivity means 'install fewer apps on trips'. Dongdian Huichong's compliant shelters and public charging follow the national unified interface, so residents can plug-and-charge with mainstream platforms; we suggest prioritising 'whether it joins the interconnect platform' when choosing a stall, making the doorstep pile both handy at home and seamlessly refillable away—turning 'pile-ocean tactics' into real convenience.
