Technical Field

[0001] The invention relates to an automobile component, in particular to an aluminum-coated new energy automobile battery connector and a manufacturing method thereof. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with new technologies, new structures, and advanced technical principles.

[0003] Currently, the main new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.; among them, pure electric vehicles are powered by rechargeable batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries or lithium-ion batteries).

[0004] The battery in a pure electric vehicle is the heart of the vehicle and also the most core component. After driving a certain mileage, the battery needs to be removed frequently for inspection, maintenance or replacement. However, most of the existing battery conductive wire connections are fixed and welded, which improves the firmness of the electrical connection but is not conducive to disassembly and assembly.
