Electric automobile and foreign object detection device for electric automobile

Abstract

The invention discloses an electric automobile and a foreign object detection device for the electric automobile. The foreign object detection device comprises a shell used for being fixedly connectedwith the body of a target electric automobile, wherein the shell is internally provided with an infrared thermal imaging camera used for detecting a foreign object in the charging environment when the target electric automobile is wireless charged, a camera steering engine used for adjusting the shooting range of the infrared thermal imaging camera and a main controller used for performing electric control. The heat in the charging environment is detected through the infrared thermal imaging camera and can be processed into a thermal infrared image, thus whether there is a metal foreign object or a living body between the electric automobile and a wireless charging device or not is judged, the camera steering engine enables the foreign object detection device to adapt to different modelsof electric automobiles, the shooting angle of the camera can be adjusted, and the infrared thermal imaging camera is enabled to be flexibly aligned to a transmitting coil of the wireless charging device, so that accurate detection for a foreign object in the wireless charging environment of the electric automobile is achieved, and thus the safety of wireless charging is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to an electric vehicle and a foreign object detection device for the electric vehicle. Background technique [0002] Wireless charging (power supply) belongs to the new high-tech industry, and many products have already entered the homes of ordinary people. Wireless power supply (charging) technology is an ideal combination with electric vehicles. Wireless power supply safety, high reliability, easy to use, anti-corrosion pollution. Because the basic principle of wireless power supply still belongs to electromagnetic interaction, it is required that there should be no ferromagnetic material between the transmitting coil and the receiving coil. Because the ferromagnetic material will generate eddy current heating in the entire closed magnetic field, which not only reduces the efficiency, but also has the risk of scalding the transmitting coil and catching fire.

AI Technical Summary

Problems solved by technology

Since the charging of electric vehicles is a relatively high-power wireless charging, if there are foreign objects between the electric vehicle and the charging equipment, especially ferromagnetic foreign objects, it is easy to cause danger.
