This document also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries).

Aspects covered in this document:

？ safety requirements of the battery swap system and its systems;

？ security requirements for communication;

？ electromagnetic compatibility (EMC);

？ marking and instructions;

？ protection against electric shock and other hazards.

This document is applicable to battery swap systems for EV equipped with one or more SBS/HBS.

This document is not applicable to
