Abstract

The invention discloses an electromobile and a high-voltage power distribution box. The high-voltage power distribution box comprises a controller, a high-voltage anode contactor, a high-voltage cathode contactor, a high-voltage pre-charging contactor, a pre-charging resistor, a high-voltage input end connector clip, a high-voltage part connector clip and a high-voltage interlocking line. The high-voltage power distribution box completes basic power source distribution and current protection; on one hand, the controller is arranged inside the high-voltage power distribution box, so that only several necessary lines such as a communication bus, a controller ground line and a power source line are needed for connection with the outside, and higher safety is realized; on the other hand, the high-voltage power distribution box is provided with the high-voltage interlocking line which is connected with the high-voltage input end connector clip and the high-voltage part connector clip, and once one connector clip is loose or off, the controller controls all contactors to be off, so that safety of the high-voltage power distribution box is further improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle and a high-voltage power distribution box. Background technique [0002] With the development of electric vehicle technology and the country's strong support for energy conservation and emission reduction, electric vehicles have become more and more popular, but the resulting safety issues have also been paid more and more attention. There are many high-voltage electrical components on electric vehicles, such as battery packs, motors, PTC heaters, DC / DC circuits, electric air-conditioning compressors and other components. The high-voltage distribution box for high-voltage circuits has become an indispensable device on the car. The high-voltage power distribution box in the prior art only has some components such as relays and insurance, and is more used as a device for power distribution and current protection, and does not have a high level of safe...
