T/CAAMTB 55.5—2021 is part of the specification series for shared battery-swapping stations serving electric passenger vehicles. CABIA appears among the drafting organizations, with the China Association of Automobile Manufacturers responsible for the standard. The public catalogue covers battery-pack dimensions for electric passenger vehicles using chassis-based swapping. The chassis-swapping and passenger-vehicle boundaries matter; the entry does not imply universal dimensions for all battery packs. Its registered implementation date is 1 January 2022. This resource summary is based on catalogue metadata; technical limits and detailed requirements have not been inferred from the title or reconstructed without the final text.
