Two-wheeled electric vehicle wireless charging system and foreign matter detection and power adjustment method

Abstract

The invention discloses a two-wheeled electric vehicle wireless charging system and a foreign matter detection and power regulation method. The system comprises a single rectification circuit D1-D4, a PFC circuit DF1-LF1-GF1, a half-bridge inverter circuit S1-S2, an LC compensation circuit C1-C2-L2-C2-L2, a rectification circuit Dr1-Dr4, a transmitting end controller, and a receiving end controller. The transmitting end controller comprises a transmitting end MCU processor, a drive circuit module and a transmitting end communication base station. The receiving end controller comprises a receiving end MCU processor and a receiving end communication base station. According to the two-wheeled electric vehicle wireless charging system and the foreign matter detection and power adjustment method of the invention, wired charging is replaced by wireless charging; the system comprises the single rectification circuit D1-D4, the PFC circuit DF1-LF1-GF1, the half-bridge inverter circuit S1-S2, the LC compensation circuit C1-L2-C2-L2, the rectification circuit Dr1-Dr4, the transmitting end controller and the receiving end controller; the transmitting end controller adopts a constant-voltage and constant-current charging mode according to detected state information of a vehicle-mounted battery Ub, and the transmitting end controller adjusts the transmission power of the system by adjusting the working frequency of the system so as to charge a two-wheeled electric vehicle.

Description

technical field [0001] The invention relates to the technical field of charging two-wheeled electric vehicles, in particular to a wireless charging system for two-wheeled electric vehicles and a foreign object detection and power adjustment method. Background technique [0002] The number of electric bicycles in my country has reached 300 million, and there are as many as 100 million charging times per day. However, since most old communities do not have charging facilities such as charging sheds or charging piles, it is very common for residents to privately pull electric wires to charge electric bicycles. Generally, however, there are great potential safety hazards in privately pulled wires. Residents’ privately pulled wires are not equipped with protective facilities. When the wires are suspended in the air, they are easily rubbed against the wall, causing the wire body to wear out, causing leakage accidents, and privately pulled wires It is also easy to short circuit and c...
