In view of the above challenges and requirements of high-voltage cables used in electric vehicles, it is necessary to establish new cable standards to meet the needs of suppliers, wire harness manufacturers and OEMs.
This work is being carried out by the Vehicle Cables Working Group (ISO/TC 22/SC 3/WG4) of the Electrical and Electronic Subcommittee of the Road Vehicles Technical Committee of the International Organization for Standardization.
It can be seen from ISO 6722 that the standard for 60 V cables has been revised to meet the requirements for 600 V cables. Because most of its requirements are still very general, but often do not consider the special design required by high-voltage cables. ISO 14572 has been similarly revised.
At present, the standardization of high-voltage cables with voltage higher than 600V is a subject of each working group. The standard number is ISO 17195.
SAE will adjust the requirements of the current high voltage (rated 600 V) specification SAE J1654 for high voltage cables, and cover the rated voltage from 600 to 1000 V. The newly created and unpublished standard SAE J2840 will be defined as shielded cables.
