Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as 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-altitude air-conditioning controllers in new energy vehicles, wherein each controller 1 is connected when the high-voltage connector is connected The interior is airtight, and there is no light inside. When the high-voltage connector is disconnected, the light penetrates into the controller 1 through the high-voltage connector socket 5, and the external high-voltage connection can be realized by detecting the light inside the controller 1. The detection of the state, the specific method used is: detect whether there is light inside the controller 1; when it is detected that there is light inside the controller 1, judge that...

The invention discloses a controller high-voltage interlocking detection method and 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. The method comprises specific steps that whether light exist in the controller is detected; when it is detected that light exists in the controller, it is judged that the controller is in an external high-voltage disconnection state; when it is detected that no light exists in the controller, it is judged that the controller is in an external high-voltage connection state; and when the controller is in the external high-voltage disconnection state or external high-voltage connection state, 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...
