An overview of standards for electric vehicle charging cables

In response to the challenges and requirements of high voltage cables for new energy electric vehicle applications, there is a need for new cable standards to meet the needs of suppliers, wire harness manufacturers, and host plants.

As can be seen on ISO 6722, the standard based on the common 60 V cable has been revised to meet the needs of 600 V cables. Because most of its requirements are still very general, but often do not take into account the special design required for high-voltage cables. ISO 14572 has been similarly revised.

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 cover voltage ratings from 600 to 1000 V. The newly created yet-to-be-published standard SAE J2840 will be defined as a shielded type of cable.

Among them, LV is the common procurement specification of the five major German automotive companies, which currently introduced 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. The national automotive industry standard for high-voltage shielded cables will be rated at 600-1000 V and will require 2.5-70 mm2 cables as judged by the cable cross-sectional area.
