Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] like Figure 1 to Figure 3 As shown, the high-voltage interlock detection method of this embodiment is applied to high-voltage accessories such as high-voltage controllers, high-voltage power distribution, and high-voltage air-conditioning controllers in new energy vehicles. When each controller 1 is connected to high voltage, the corresponding high-voltage The plug on the connector plug 6 will be inserted into the through hole of the high-voltage connector socket 5. The specific method used is:
[0036] 1) Detect the distance between the preset position inside the controller 1 and the plug on the high-voltage connector plug 6 of the controller;
[0037] 2) Compare the detected distance with the preset threshold; when the detected distance is greater than the preset threshold, it is judged that the controller 1 is disconnected from the ...

The invention discloses a controller high-voltage interlocking detection method, a detection device and a controller, belongs to the technical field of high-voltage detection, and is used for solving the technical problems of low reliability, complex operation, high cost and the like of current high-voltage detection, and the method specifically comprises the following steps: 1) detecting the distance between a preset position in the controller and a high-voltage connector plug of the controller; 2) comparing the detected distance with a preset threshold value; when the detected distance is larger than a preset threshold value, it is judged that the controller and the external high voltage are in a disconnected state; when the detected distance is within a preset threshold value, it is judged that the controller and the external high voltage are in a connection state; and when the controller is disconnected from the external high voltage or connected with the external high voltage, a corresponding state signal is generated to perform high voltage interlocking. The method, the device and the controller have the advantages of being easy and convenient to operate, low in cost, reliable in detection and the like.
Description
technical field [0001] The invention mainly relates to the technical field of high-voltage detection, in particular to a controller high-voltage interlock detection method, device and controller. Background technique [0002] With the application of new energy vehicles, high-voltage controllers, high-voltage power distribution, and high-voltage air-conditioning controllers are more and more widely used. In order to protect the lives of passengers and maintenance personnel, it is necessary to ensure , need to make a corresponding protection strategy. Among them, the high-voltage interlock is to ensure that when the high-voltage line of the high-voltage controller is disconnected, the controller can take related measures such as disconnecting the high-voltage power to ensure the safety of people. [0003] Current related patent applications include: [0004] 1) Title: A high-voltage interlock device (application number: CN201910251784.8) [0005] The invention discloses a h...
