Problems solved by technology
[0008] In order to solve the problem of difficult charging of electric vehicles in parking lots with no charging piles or few charging piles, a magnetic levitation-based charging system for electric vehicles is designed by using the principle of magnetic levitation outer rotor flywheel energy storage combined with ground mobile robot technology. The ground mobile charging robot with external rotor flywheel energy storage realizes automatic charging of electric vehicles in any parking space in the parking lot

The invention discloses a magnetic suspension outer rotor flywheel energy storage-based ground mobile charger robot applied to an electromobile. In the robot, position change between a charging base station and a target charging vehicle is achieved by an ultrasonic sensor, a visual sensor and rollers which are arranged on a bearing piece, and automatic charging of the electromobile is achieved by two magnetic suspension energy-storage flywheels which are assembled in a base and are opposite in rotation directions. The magnetic suspension energy-storage flywheel comprises a first assembly, a second assembly, a third assembly, a flywheel upper cover and a flywheel lower cover from inside to outside, the high-speed rotation of the magnetic suspension energy-storage flywheel is dependent on driving of a rotation alternating magnetic field, the alternating magnetic field is implemented according to a working principle of a flat hollow-cup DC motor, electrical energy is converted to rotation kinetic energy of a rotation assembly, and the purpose of high-speed rotation is achieved; and after the two magnetic suspension flywheels reach rated rotational speeds, the charging of the robot is completed.
Description
Technical field [0001] The present invention relates to a charging robot, and more particularly, to a ground mobile charging robot based on magnetic levitation outer rotor flywheel energy storage applied to electric vehicles. Background technique [0002] Pure electric vehicles have the advantages of environmental protection, low noise, small size, etc., and have broad application prospects for future urban traffic. However, due to various technical reasons, the application and popularization of pure electric vehicles are restricted. One of the more prominent problems is the difficulty of charging. Mainly reflected in the following aspects: [0003] (1) Long charging time, 3 to 5 hours for fast charging and more than 10 hours for slow charging. [0004] (2) The charging depth is not enough, and most electric vehicles cannot reach the rated mileage after being fully charged. [0005] (3) The charging pile is fixed, which is easy to be occupied by other vehicles. [0006] (4) Charging ...
