It adopts a centralized power distribution solution, with a compact structural design, convenient wiring layout, and convenient and quick maintenance. The high-voltage distribution box provides charging and discharging control, power-on control of high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control and other functions for the high-voltage system of new energy vehicles to protect and monitor the operation of the high-voltage system. Its main connected components include power battery packs, on-board chargers, motor controllers, DC / DC converters, electric air conditioners, PTC and other high-voltage electrical equipment. The internal devices include high-voltage contactors, fuses, connectors, copper bars, etc., which are responsible for the reasonable control and protection of the circuit.
