From watch to net
The 'defence line' of charging safety upgrades from 'person-watches-person' to a 'technology net'. Past reliance on patrols and awareness couldn't stop overcharge, short-circuit and battery thermal runaway; now IoT links 'vehicle-stall-grid'—smart smoke sensors, temperature sensors and voltage/current modules report in real time, the platform auto-warns on overcharge, overload, temperature anomaly and fault, nipping fire in the bud. Hangzhou Fuyang applies this to estate underground garages: a uniform 'five-one' kit (smart smoke alarm, fire blanket, fire board, car mover, trolley extinguisher) plus an integrated smart warning platform watching charge state, stall parameters, grid load and line temperature 24h.
Second-level response
More advanced landings already respond in seconds. Guangzhou pushes smart fire safety at 9,000 stations with heat-sensing cable + AI camera dual backup, water-on-flame within 5s, initial fire out within 30s, process '1-min alarm, 3-min arrive, 5-min handle'; Nanchong's 'little green stalls' have six protections (over-current/short/over-charge/over-voltage/over-temp/linkage), built-in temperature module linking site smoke sensors, cutting power and alarming on over-temp or smoke. Standards catch up: XF/T 3024—2026 and GB 47371—2026 require 3C certification, 470MHz/LoRa/4G/NB-IoT networking, and stalls must have overload/short/leakage protection, full-stop and time-limit cut, supporting third-party smart-fire cloud.
Yantai's visible ease
For Yantai owners and operators smart fire safety is 'visible ease'. Dongdian Huichong's community and public charging reminds residents: pick stalls with 3C and networking warning, rejecting unprotected 'three-no' gear; operators should connect sites to smart-monitoring platforms, equip the 'five-one' kit and maintain regularly, making safety a verifiable closed loop. Charging safety has no 'small matter'—technology holds the line, institutions back it, and green travel truly reassures.
