Anxiety net torn
Long trips once terrified NEV owners with 'service-area queues'; that anxiety net is now torn by mega-charge corridors. In Aug 2026 the MOT energy-support office declared ten trunk expressway mega-charge corridors fully linked, covering G4 Jinggang'gang, G2 Jinghu, G15 Shenhai, G30 Lianhuo, G45 Daguang, G55 Er'guang, G60 Hukun, G65 Baomao, G75 Lanhai and G85 Yukun. The bar is hard: each service area (avg 40–50km apart) gets ≥1 mega station with ≥4 liquid-cooled guns (≥360kW peak) and ≥98% availability.
Scale and experience
Scale and experience both land. The ten corridors cover ~860 areas with ~6,900 mega guns; nationwide ~28k mega guns make ~31% of expressway DC guns. The test is convincing: an 800V car on Jinggang'gang's ~2,300km needed only ~55 min total refill (3×~18 min), ~2.4% of drive time—a '10-min charge, 400km range' circle basically forms on trunk lines. Nationwide expressway stalls exceed 71.5k, covering >98% of areas; NEA targets 40k 60kW+ guns by end-2027.
Yantai's road confidence
For Yantai and nearby owners mega corridors are 'road confidence'. Dongdian Huichong's community and public charging reminds: holiday refill planning can be calmer, but avoid peaks and pick liquid-cooled stations; operators can borrow the 'storage buffer + solar-storage' power fix—weak-grid sections cut 40–60% demand with storage and arbitrage valley-to-peak, lowering capacity cost while earning. With the '10-min circle' formed, green travel's radius is really lengthened.
