Charging alarm system for electric automobile and working method of charging alarm system

Abstract

The invention relates to the field of intelligent charging of electric vehicles, and particularly discloses a charging alarm system for an electric vehicle and a working method thereof, and the system employs a convolutional neural network model of a deep learning technology to extract high-dimensional implicit features of a magnetic field distribution diagram based on the magnetic field distribution of a transmitting coil and a receiving coil. And high-dimensional correlation feature information between the magnetic field distribution of the transmitting coil and the magnetic field distribution of the receiving coil is fused by using a Gaussian density map, so that the classification result is more accurate. In this way, the type of the foreign matter can be accurately recognized, and therefore different alarm levels are set based on different types.

Description

technical field [0001] The invention relates to the field of intelligent charging of electric vehicles, and more specifically, to a charging alarm system for electric vehicles and a working method thereof. Background technique [0002] With the continuous consumption of petroleum energy and the aggravation of environmental pollution, the electric vehicle industry is strongly supported by governments of various countries and is in a stage of rapid development. As the carrier of electric vehicle charging energy supply, the wireless charging transmitting coil is a key part of wireless charging technology. Since its working environment is generally outdoors, various foreign objects such as coins, cans, and fallen leaves may appear on its surface at any time, which will seriously reduce the working efficiency of the transmitting coil during work and cause safety accidents.

Problems solved by technology

Since its working environment is generally outdoors, various foreign objects such as coins, cans, and fallen leaves may appear on its surface at any time, which will seriously reduce the working efficiency of the transmitting coil and cause safety accidents

[0003] At the same time, different foreign objects have different effects on charging. Foreign objects such as fallen leaves have little effect on charging, while metals such as cans have a greater impact on them, and may cause fire and other safety hazards.
