High-voltage distribution boxes are a foundational element in modern new-energy vehicles, serving as the electrical backbone that safely routes, protects, and measures high-voltage energy flow between batteries, inverters, motors, and charging interfaces. It is responsible for collecting the direct current (DC) output from multiple battery clusters, providing necessary protection and monitoring, and. The high-voltage power supply system is a core component of new energy vehicles. It is also closely related to the overall vehicle cost. With advanced, high-quality components, rugged durability and compact size, it's what you want to drive your next EV project. The top the es for the year were: stability,market shift,and key clients.
