In the faint light of dawn, before the city is fully awake, a new fleet of electric refrigerated trucks has quietly set off. Their cargo compartments are filled with fresh produce, medical supplies, and delicate food ingredients, traveling along digitally optimized routes to every corner of the city. This isn't a science fiction scenario, but a transformation in cold chain logistics that is already underway – electric vehicle refrigeration units are redefining the future of cold chain transportation in an unprecedented way.

Deep within the pulse of the city, cold chain logistics, like the city's capillaries, maintains the freshness and health of modern life. The roar and exhaust emissions of traditional refrigerated vehicles, however, impose environmental and noise costs on this delivery of "freshness." Now, this situation is being completely changed.
