Problems solved by technology

Each charging parking space must have a complete wireless charging system, and the wireless charging device in the parking space without charging will be idle, which will lead to a waste of resources
[0003] Wired charging has charging piles and charging clusters, but it will independently allocate charging power lines to each charging pile, requiring an independent power distribution unit to complete power distribution, requiring switches or relays to switch outputs, which reduces reliability and system configuration. quite complicated

Abstract

The invention discloses a wireless charging system having a power distribution function. The wireless charging system comprises a plurality of AC / DC power modules, a plurality of wireless power sending units, a power distribution strategy processing unit and wireless power receiving units, output ends of the AC / DC power modules come together to form a direct-current bus mounted on a parking place needing to be charged, the direct-current bus is in line connection with the wireless power sending units, the power distribution strategy processing unit is in line connection with the AC / DC power modules and the wireless power sending units through communication lines, and the wireless power sending units and the wireless power receiving units are in wireless signal connection. The wireless charging system provides intelligent distribution solutions of charging power; especially for the wireless charging system in large-scale arrangement, cost is lowered; charging use efficiency of electric vehicles is improved.

Description

technical field [0001] The invention relates to the field of wireless charging of electric vehicles, in particular to a wireless charging system with power distribution, which is applied in parking lots, underground garages, three-dimensional garages and other occasions where wireless charging terminals are deployed on a large scale. Background technique [0002] In the field of wireless charging of electric vehicles, especially in areas where charging devices are densely arranged, such as parking lots, garages, etc., the current wireless charging system is from AC input to wireless power transmission. Wireless power reception and battery docking charging are one Complete standalone system. Each charging parking space must have a complete wireless charging system, and the wireless charging device of the parking space that is not charging will be idle, which will lead to a waste of resources. [0003] Wired charging has charging piles and charging clusters, but it will indep...
