Wireless charging detecting system for electromobile

Abstract

The invention provides a wireless charging detecting system for an electromobile. The wireless charging detecting system comprises an electric energy providing device, an electric energy receiving device and a battery manager. The electric energy providing device is connected with a charging station, and the electric energy receiving device and the battery manager are located on the electromobile. The electric energy providing device is used for transmitting electric energy to the electric energy receiving device through electromagnetic induction. The electric energy receiving device is located on the electromobile, and used for further transmitting the electric energy provided by the electric energy providing device to a vehicle-mounted power battery of the electromobile and carrying out self-checking in real time after the wireless charging procedure is started, and if a fault is detected, the electric energy receiving device sends a fault signal to the battery manager. The battery manager is used for disconnecting a wireless charging loop to stop wireless charging after receiving the fault signal. By means of the wireless charging detecting system, the safety and reliability of a charging device can be improved, and the service life of the charging device can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a wireless charging detection system for electric vehicles. Background technique [0002] With the continuous promotion of new energy vehicles, especially electric vehicles or hybrid vehicles, new energy vehicles have become increasingly relevant to our daily life. At present, the charging method of electric vehicles is mainly a wired charging method, but there are many shortcomings in the conventional wired charging method, and the wireless charging method can make up for these shortcomings. [0003] At present, wireless charging has begun to be applied in some low-power charging fields, such as mobile phone charging. However, the high-power wireless charging equipment used for charging electric vehicles is still in its infancy, and there are still many shortcomings, such as fewer system detection functions, imperfect control strategies, and charging power cannot be c...

AI Technical Summary

Problems solved by technology

However, the existing wireless charging scheme for electric vehicles does not have a complete monitoring function, and it is impossible to detect the operation of each component in the system and the electrical parameters of each component in real time.

Moreover, the existing wireless charging solutions for electric vehicles cannot provide protection measures for electric vehicles, and cannot change the charging power according to the information of the vehicle's power battery.
