Problems solved by technology

However, if all the high-voltage devices suddenly cut off the high voltage during the high-speed operation of the vehicle, it will cause the power steering system of the new energy vehicle to fail, making it difficult for the driver to change the running track of the new energy vehicle, which may cause the new energy vehicle to fail. The car deviates from the correct driving route, and an accident occurs when it runs out of the road or collides with an adjacent car

Abstract

The invention discloses a new energy automobile and a high-voltage electrical system thereof. According to the high-voltage electrical system of the new energy automobile, a circuit structure and a high-voltage power-off strategy of the high-voltage electrical system are redesigned, and unnecessary high-voltage power failure of a power-assisted steering system is thus avoided; due to the failure of the power-assisted steering system of the new energy automobile, it is difficult for a driver to change the vehicle trajectory and thus an accident may be resulted, however, by the redesign, the probability of such accident is also reduced.

Description

technical field [0001] The present application relates to the technical field of high-voltage electrical systems of new energy vehicles, and more specifically, relates to a new energy vehicle and its high-voltage electrical system. Background technique [0002] The high-voltage electrical system of new energy vehicles mainly includes electric power steering system, drive motor system, electric air compressor system, DC converter, electric defrosting system and electric air conditioner. Provided by the battery, the vehicle controller of the new energy vehicle controls the high-voltage power-on and high-voltage power-off of the high-voltage electrical system. When any high-voltage device constituting the high-voltage electrical system has a secondary failure, the vehicle controller will reduce the power of the high-voltage electrical system to reduce the speed of the new energy vehicle; when When any one of the high-voltage devices constituting the high-voltage electrical sys...
