Traditional high current connectors often relied on solid pin designs, which, while functional, had limitations in terms of contact area and flexibility. In contrast, modern designs like the crown spring connector offer significant advantages. The spring-loaded mechanism of the crown spring connector provides a larger contact surface area, reducing electrical resistance and heat generation. This design also allows for better tolerance of misalignment and vibration, crucial factors in the dynamic environment of a moving vehicle. Additionally, the crown spring connector's construction often incorporates advanced materials that enhance durability and conductivity. These improvements translate to more efficient power transfer, reduced energy loss, and increased overall reliability of EV battery systems.
