CWA 16688:2013

This CEN-CENELEC workshop agreement proposes standards which enable the mass adoption of EV with swappable battery packs by defining simple, robust and reliable interfaces between EV, swappable battery pack and battery swap system (BSS). This agreement will cover the proposed architecture and design for automotive components which connect the battery pack to the vehicle and the BSS. This document deals with passenger vehicles of classes A to D and light commercial vehicles (LCV) of class LCV 1, with a swappable battery pack.
The CWA provides both general guidance, codes of practice and requirements for designing those components. Safety aspects are out of the scope of this document and are dealt with in other standards such as ISO 26262, which covers functional safety of automotive components and subsystems. Battery swapping systems’ safety is covered in IEC 62840.
