New energy vehicle charging gun test

On September 7, 2023, the new national standard for new energy vehicle charging guns GB/T 20234.1-2023 "Connection Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements" was officially released and came into effect. Compared with GB/T 20234.1-2015, GB/T 20234.1-2023 puts forward more stringent requirements for charging guns in terms of safety, durability and reliability.
