Standardization status of electric vehicle cables

- Oct 04, 2019-

For the challenges and requirements of high voltage cables for electric vehicle applications, it is necessary to establish new cable standards to meet the needs of suppliers, wire harness plants and OEMs.

This work is being carried out by the Working Group on Vehicle Cables of the Electrical and Electronic Subcommittee of the International Organization for Standardization Road Vehicle Technical Committee (ISO/TC 22/SC 3/WG4).


As seen on ISO 6722, it has been revised based on the common 60 V cable standard to meet the requirements of 600V cable. Because most of its requirements are still very versatile, the special design required for high voltage cables is often not considered. A similar revision was made to ISO 14572.


The standardization of high voltage cables with voltages higher than 600V is currently a subject of various working groups. The standard number is ISO 17195.


SAE will adjust the current high voltage (rated 600 V) specification SAE J1654 for high voltage cables and covers voltage ratings from 600 to 1000 V. The newly created standard SAE J2840 will be defined as a shield type cable.


LV is the common procurement standard of Germany's five major auto companies, and currently introduces the standard LV 216 for high-voltage cables for electric vehicles with a rated voltage of 600 V. It covers single-core and multi-core shielded cables.


China's national automotive industry standards for high-voltage shielded cables are under development and will be rated at 1000 V.
