Description

Wireless charging system of electric bicycle

Technical Field

The utility model belongs to the technical field of electric bicycle charges and specifically relates to a wireless charging system who charges is concentrated to electric bicycle.

Background

The battery car is also called as an electric bicycle, and is a mechatronics personal transportation tool which takes a storage battery as auxiliary energy and is provided with a motor, a controller, the storage battery, a rotating handle brake handle and other operation components and a display instrument system on the basis of a common bicycle. In recent years, the method has been widely popularized in China.

However, the problem of inconvenience in charging electric bicycles is more and more prominent. On the one hand, in some cells without centralized charging, a resident on the floor needs to push the electric bicycle to the floor or separate the battery to take it to the floor for charging. It is a very troublesome matter for the cart to go upstairs, especially in cells with partly no elevator; and many electric bicycles are for preventing burglary, and the battery is welded and fixed on the frame and cannot be detached. Even if the electric bicycle can partially disassemble the battery, as the capacity of the battery is continuously improved (from the initial 36V/12Ah to the current 48V/24Ah), the volume and the weight of the used lead-acid battery become larger, and even if the partial battery can reach 30Kg, the disassembly and the transportation become more inconvenient. Therefore, there are some cells that use a centralized charging management approach. At present, concentrated charging of a community belongs to wired charging, a large number of socket ports need to be additionally arranged, and a charger is used for connecting a socket and an electric bicycle. When an electric bicycle causes a fire due to faults of aging, heating, short circuit and the like, the centralized wired charging mode has a catastrophic effect, and a fire report of a cell caused by the charging of the electric bicycle is often seen.

At present, a wireless charging mode is developed in the field of electric automobiles, and a low-frequency (85KH) magnetic resonance mode is used for wirelessly charging batteries of the electric automobiles. However, this wireless charging system needs to align the coil of the vehicle with the coil buried in the ground to ensure high charging efficiency.

The existing positioning technologies are roughly divided into two types:

1) the first is that a plurality of cameras are arranged on a receiving device at the bottom of the vehicle, and the personnel controls the vehicle to be aligned above a transmitting coil on the bottom surface through images of the cameras.

2) In another mode, the bottom surface transmitting coil is mechanically driven by a motor to move, and the transmitting coil is driven by the mechanical motor to be aligned with a receiving device of the vehicle through various positioning methods.

The above two positioning methods have the following disadvantages:

1: additional vehicle components are increased, adding to the video and associated wiring harnesses and production costs.

2: if the position of charging adopts mobilizable emitter, the overall structure of the parking stall of charging is complicated, and the mechanical structure under the bottom surface is complicated, and the cost of single wireless potential of charging is with high costs, is unfavorable for wireless charging technology's popularization.

Therefore, there is a need to provide a new wireless charging system for electric bicycles to solve the above problems.
