What are the technical standards for EV fuses on new energy vehicles?
There are several technical standards that apply to the New energy Fuse of Contact Knife Caps used in new energy vehicles (NEVs), including the following:
1-GB/T 20764-2014: This standard applies to the Electric Vehicle Fuse of End Cap and Contact used in low-voltage DC circuits in electric vehicles. It specifies the requirements for the construction, performance, and testing of fuses used in NEVs.
2-GB/T 31467.3-2015: This standard applies to New Energy Electric Vehicle Fuse of End Cap and Contact Welding Components used in on-board DC charging systems for electric vehicles. It specifies the requirements for the construction, performance, and testing of fuses used in these systems.
3-ISO 8820-8: This international standard specifies the requirements for blade-type fuses Design of Welded Joints used in the electrical systems of road vehicles, including NEVs. It covers the physical dimensions, electrical characteristics, and performance of blade-type fuses.
4-SAE J1888: This standard specifies the requirements for Fusible Link End Cap and Terminal used in high-voltage DC circuits in hybrid and electric vehicles. It covers the construction, performance, and testing of fuses used in these systems.
5-UL 248-19: This standard applies to Bolt Connection Type Quick Fuse used in DC circuits up to 1,500 volts. It covers the construction, performance, and testing of fuses used in NEVs and other DC applications.
These standards provide guidance for the selection, installation, and testing of New Energy Vehicles Fuse used in NEVs, and ensure that they meet certain safety and performance requirements. It is important to consult these standards and other relevant regulations when selecting fuses for NEVs to ensure they are safe and reliable.
