Wireless charging system and method for vehicles

Abstract

The invention discloses a wireless charging system and method for vehicles. The wireless charging system comprises a vehicle-mounted charging apparatus, a ground charging apparatus and a charging main control apparatus; the vehicle-mounted charging apparatus comprises wireless labels, a receiving coil and a battery, and a first controller, wherein the wireless labels are equipped with vehicle identification information; the receiving coil is used for charging the battery; the first controller is used for controlling the on-off of the receiving coil; the ground charging apparatus comprises a wireless reader, a power supply and a transmitting coil, a resonance vibration generator and a second controller, wherein the wireless reader is used for reading the wireless labels of vehicles within a preset range; the transmitting coil and the receiving coil are electromagnetically coupled for transmitting the electric energy of the power supply to the battery; the resonance vibration generator is used for converting the electric energy of the power supply into resonance wave, and transmitting the resonance wave through the transmitting coil; the second controller is used for controlling the on-off of the transmission coil; and the charging main control apparatus is used for sending opening instructions to the first controller and the second controller when a charging process is performed according to the judgment of the wireless labels. According to the wireless charging system, the working efficiency and use experience of an operator are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a wireless charging system and method for vehicles. Background technique [0002] As the most popular new energy application example at this stage, electric forklifts have broad development prospects. In actual use, electric forklifts usually work in relatively fixed areas such as warehouses, airports or factories. The use time is long, and the discharge time is short. It is often necessary to stop halfway for charging, and the charging time will be at least one hour. Moreover, the electric forklifts currently on the market have to stop at a fixed position every time they are charged, and they are charged through a bulky charging cabinet and a charging gun. The problems in the above aspects have seriously reduced the efficiency of electric forklifts and hindered the rapid development of electric forklifts. [0003] In order to simplify the charging process, the genera...

Problems solved by technology

Although this charging method gets rid of the heavy charging cabinet and charging gun of the forklift, it is still very troublesome to accurately park the electric forklift at the designated charging location, so the user experience is still poor
