Electric vehicle charging system based on electromagnetic position detection and control method thereof

Abstract

The invention discloses an electric vehicle charging system based on electromagnetic position detection and a control method thereof. The system is provided with a signal receiving circuit and an on-board controller in the electric vehicle, and the launching guide rail is set as a multi-section guide rail type. Each section of the guide rail is provided with a wireless energy transmitting coil, asignal generating circuit and a control circuit. When the vehicle enters the guide rail, the signal receiving circuit receives the high-frequency excitation signal and sends it to the on-board controller. The on-board controller processes the signal and sends it to the control circuit, which controls the switching state of the energy transmitting coil. A control method applied to the system comprises the following steps: S1, a guide rail sends a signal; S2, the vehicle receives the signal; 3, the signal is processed by the on-board controller and transmit to the control circuit; S4: The control circuit controls the on-off state of the energy transmitting coil. The remarkable effect of the invention is that the dynamic intelligent charging of the electric vehicle is realized, the waste of energy is avoided, and the charging of the electric vehicle is more efficient.

Description

technical field [0001] The invention relates to the technical field of electric vehicle wireless charging, in particular to an electric vehicle charging system based on electromagnetic position detection and a control method thereof. Background technique [0002] The traditional automobile industry has developed to the level of technological maturity. In recent years, with the advancement of electric technology, new electric vehicles have gradually shown their broad development prospects. Electric vehicles refer to vehicles powered by on-board power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic safety regulations. The most widely used on-board power supply for electric vehicles at this stage is the battery. [0003] With the rapid increase in the number of electric vehicles, their shortcomings such as insufficient battery life, long charging time, imperfect infrastructure, and inability to support long-distance travel continue to e...
