This part of IEC 61851 covers Electromagnetic Compatibility (EMC) requirements for conductive connection of an electric vehicle (EV) to an a.c. or d.c. supply. It applies only to on-board charging systems either tested on a host vehicle or tested on the charging system component level (ESA – electronic sub assembly). In case the onboard charger (OBC) is tested on host vehicle level, it is important to note that this standard does not set any requirements for the vehicle as a whole. Vehicle requirements are defined e.g. in CISPR 12 or the ISO 11451-series.
This part is also recommended for industrial trucks and vehicles designed primarily to be used off-road, e.g. forestry and construction machines, in charging mode.
This part of the standard is not applicable to trolley buses and rail vehicles.
Bi-directional power transfer between EV RESS and the grid (for vehicle to grid in grid-following mode) or a load/islanded installation (for vehicle to load or home in grid-forming mode) will be treated in a future revision of this standard. Until then, vehicle in grid-following mode shall be treated as an additional operating mode for emission requirements and the same requirements shall be applied.
NOTE 1 Specific safety requirements that apply to equipment on the vehicle during charging are treated in separate documents as indicated in the corresponding clauses of this document.
NOTE 2 Electric vehicle (EV) includes pure electric vehicles as well as plug-in hybrid electric vehicles with additional combustion engine.
NOTE 3 In the near future, due to new grid codes, the use of 61000-3-16 can be necessary for the reverse power transfer mode. The measurement of DC-injection acc. to a future standard can be necessary as well.
