The invention discloses a high-voltage power distribution box. The high-voltage power distribution box comprises a box body; a box cover is arranged on the box body; a control unit, a short circuit protection unit and a power distribution unit are arranged in the box body; the control unit comprises a relay unit; the short circuit protection unit comprises a short circuit protector; the power distribution unit comprises a transfer busbar; the interior of the box body is divided into an upper-layer structure and a lower-layer structure; the short circuit protection unit is arranged at the upper-layer structure; the control unit and the power distribution unit are arranged at the lower-layer structure; an input end of the short circuit protector is connected with a positive pole of a power source, while an output end of the short circuit protector is connected with an input end of the relay unit; an output end of the relay unit is directly and electrically connected with a power utilization device through an output port on an end face of the high-voltage power distribution box; a negative pole of the power source connects the transfer busbar with a negative pole of the power utilization device. The high-voltage power distribution box is reasonable in power distribution and capable of greatly reducing power losses.
Description
technical field [0001] The invention relates to a high-voltage power distribution device, in particular to a high-voltage power distribution box assembly in the field of new energy electric vehicles. Background technique [0002] With the increasingly serious environmental problems and energy crisis, new energy vehicles have emerged in this context. New energy vehicles are mainly powered by the battery system, and the energy transmission of the entire system is carried out by the high-voltage electrical system. The high-voltage power distribution box is the core component of the high-voltage electrical system. Its main function is to control the on-off of the internal high-voltage relay through the external low-voltage control circuit, and to drive and turn the high-voltage DC power supply of the power battery according to the internal design circuit of the high-voltage power distribution box. A series of high-voltage components such as the motor controller of the motor, on...
