Embodiment Construction

[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0018] Such as figure 1 , figure 2 The wireless charging system with multi-coils connected in series is shown. According to different input power, output power and space constraints of the installation site, multiple winding modules 5 connected in series are used to replace the fixed primary side of the loosely coupled transformer structure in the traditional wireless charging field. winding and secondary winding.

[0019] The winding module 5 includes a magnetic core 2 fixedly arranged on the metal plate 1 and a coil 3 arranged on the magnetic core 2 .

[0020] In one embodiment, one or more winding modules 5 are respectively used as the primary winding a...

Abstract

The invention discloses a wireless charging system employing multiple coils in serial connection. According to different input power, output power and spatial limits of mounting fields, multiple winding modules in mutual serial connection are utilized for replacing a fixed primary winding and a fixed secondary winding of a loose coupling transformer structure in the wireless charging field. The system provided by the invention is reasonable in structure and has advantages of simple structure, convenient use, flexible arrangement and high space utilization rate and the like, and solves a problem of excessive large size of a traditional loose coupling transformer effectively.

Description

technical field [0001] The invention relates to the field of wireless charging equipment for electric vehicles, in particular to a wireless charging system with multiple coils connected in series. Background technique [0002] It is known that 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 core device of the current wireless charging system loosely coupled transformers are generally round, square, DD, DDQ In other shapes, in order to ensure sufficient power transmission, the transmission coupling transformers of the above shapes are relatively large, and it is difficult to install loose coupling transformers in some three-dimensional garages, underground garages or places with narrow parking spaces, which limits the use of wireless charging. [0003] However, because wired charging equipment has a long output cable, it is easy to entangle the cables in the occas...
