Abstract

The invention discloses an electric vehicle high voltage circuit detection control device comprising a plurality of high voltage devices, a high voltage detection module, and an integral vehicle controller. The high voltage detection module is provided with a plurality of first ports and a second port, and is respectively connected with the plurality of high voltage devices by the plurality of first ports. The high voltage detection module is used for respectively detecting the plurality of high voltage devices, and is used for generating detection signals, and the detection signals comprise the detection results of the plurality of high voltage devices. The integral vehicle controller is connected with the second port of the high voltage detection module, and is used for receiving the detection signals, and is used for the control of the detection signals. The electric vehicle high voltage circuit detection control device can be used to detect the abnormal high voltage device accurately and timely, and therefore the safety performance of the electric vehicle can be improved, and the interface resources of the integral vehicle controller can be saved. The invention also discloses an electric vehicle high voltage circuit detection control method, and an electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a high-voltage circuit detection and control device for an electric vehicle, a high-voltage circuit detection and control method for an electric vehicle, and an electric vehicle with the high-voltage circuit detection and control device. Background technique [0002] Electric vehicles use power batteries as the power source, and drive the wheels through electric motors. Therefore, electric vehicles have a high-voltage circuit, and each high-voltage device in the high-voltage circuit needs to be tested. [0003] Two high-voltage loop detection schemes have been proposed in related technologies, one is to connect all high-voltage devices to the loop detection line, and the vehicle controller will perform detection, specifically as figure 1 shown. However, when a high-voltage device is abnormal, for example, the connector is loose or burned, the vehicle controller can on...
