GB/T 39752-2021 Translated English of Chinese Standard. (GBT 39752-2021, GB/T39752-2021, GBT39752-2021): Safety Requirements and Test Specifications of Electric Vehicle Conductive Supply Equipment
https://www.chinesestandard.net, Apr 17, 2021 - Technology & Engineering - 46 pages
This Standard specifies the safety requirements, test guidelines and test methods of electric vehicle conductive supply equipment. This Standard is applicable to various types of conductive supply equipment with a rated output voltage of 1,000 V AC or 1,500 V DC and below, including conductive supply equipment of Charging Mode 2, Charging Mode 3 and Charging Mode 4; conductive supply equipment that are not used for public purposes and used under special conditions (such as: explosion-proof conductive supply equipment, liquidcooled conductive supply equipment and conductive supply equipment used in plateaus above 2,000 m above sea level, etc.) are also applicable to this Standard, and the requirements of relevant standards need to be combined here.
