High-voltage interlocking detection system

Abstract

The invention relates to a high-voltage interlocking detection system which comprises a control detection unit and a first high-voltage interlocking detection loop connected with the control detectionunit. The first high-voltage interlocking detection loop is used for detecting whether the connection between a power distribution connector and a high-voltage distribution box is normal or not, andthe first high-voltage interlocking detection loop comprises an interlocking contact corresponding to the power distribution connector; the power distribution connector is connected with a load connector through a cable; a control device corresponding to a load is used for sampling an interlocking contact corresponding to the load connector in a connected load, and all control devices are in communication connection with the control detection unit. The system can be used for detecting high-voltage interlocking connectors which are about to work or in a working state under a vehicle power-on state or a vehicle charging state or a vehicle driving state, plugging failure of a plug-in of a certain part can be accurately judged, and thus corresponding processing logic or prompt can be conveniently and timely carried out when a vehicle breaks down according to detection results.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle safety control, and in particular relates to a high-voltage interlock detection system. Background technique [0002] With the rapid development of the economy, energy and environmental protection issues have become increasingly prominent, and countries around the world have begun to set their sights on energy-saving and environmentally friendly electric vehicles. [0003] Compared with traditional vehicles, electric vehicles have added high-voltage electrical equipment or power supply equipment such as motors, motor controllers, DC / DC, and high-voltage battery packs. Therefore, the hidden danger of high-voltage electric injury of electric vehicles is completely different from that of traditional vehicles. Its voltage as high as 300V and current that may reach tens or even hundreds of amperes may affect the safe use of electric vehicles at any time. Therefore, the high-voltage system of t...
