In response to the industry pain points such as tight installation space, complex wiring, and low energy utilization rate caused by the separate design of high-voltage distribution and low-voltage power supply systems in new energy vehicles, a vehicle distribution box was developed. Through the integrated design of DC/DC converter and high-voltage distribution unit, high-voltage distribution, low-voltage power supply, intelligent control, and safety protection were deeply integrated. This paper elaborately analyzes the technical characteristics and application value of this product from four dimensions: technical architecture innovation, core performance optimization, safety protection design, and real vehicle application verification, providing a reference for the integrated development of core distribution components in new energy vehicles.
