Scope
QC/T 1204.3-2024 is the English-translated version of 纯电动乘用车车载换电系统互换性 第3部分：换电机构.
QC/T 1204.3-2024 covers the battery swap mechanism of the on-board battery swap system of battery electric passenger vehicles.
It is Part 3 of the QC/T 1204 series on compatibility of on-board battery swap systems for such vehicles, which also includes Part 1 on the battery swap electrical interface, Part 2 on the battery swap cooling interface, Part 4 on the battery swap pack and Part 5 on communication between electric vehicle and battery pack.
This part specifies the interchangeability requirements for the battery swap mechanism, covering its type, structure, dimensions and parameters, which are given as technical requirements for interchangeability in Clause 4.
Clause 3 defines the battery swap mechanism as the mechanical device used to combine the battery pack with the vehicle body and to separate it again, a device that may also guide, position, limit, retain, fasten and lock, taking the definition from 3.4 of GB/T 40032-2021; it further defines the bolted battery swap mechanism, which fixes the battery box by rotating bolts.
The document distinguishes bolted and clasped mechanisms, whose structures are illustrated in informative Appendix A and informative Appendix B respectively. GB/T 19596 and GB/T 40032-2021 are cited as normative references, and their terms apply together with those defined here.
