According to CoinMeta, recently, Benxi Passenger Transport Group, Changzhou Public Transport Group, Guiyang Public Transport Group, and Lanzhou Public Transport Group have each completed strategic partnerships with CATL. These four public transport groups, covering different city levels and operational scenarios, will collaborate on areas such as power battery supply and renewal, after-sales vehicle services, city-level battery swapping networks, battery recycling, and vehicle-network interaction. This collaboration aims to advance the electrification of public transportation from vehicle emissions reduction to coordinated urban energy systems, providing a replicable path towards achieving zero-carbon cities.
