Abstract
The invention discloses a communication method for built-in coils of an electric vehicle non-contact charging device. A non-contact charging battery state monitoring signal of an electric vehicle is transmitted through a mode of signal transmission of the built-in communication coils, thereby automatically controlling a charging state. The built-in communication coils are arranged in a high-frequency-power-to-magnetic-field transmission device and a magnetic-field-to-electric-field receiving device of the non-contact charging device of the electric vehicle respectively, a communication device starts working when the electric vehicle is parked at a specified position at a set distance away from the charging device, and a signal acquired by a battery management system is fed back to a power-to-high-frequency-power device to control electric energy output of the high-frequency-power-to-magnetic-field transmission device through a standard communication transmission protocol. According to the communication method, the electric vehicle non-contact charging device adopting a built-in coil type communication system has the advantages that the system is simple in structure and free of interference of an external environment, and a control system of the electric vehicle is not required to be transformed during non-contact charging configuration or transformation of the electric vehicle.

The present invention relates to the communications field, specifically a kind of communication means of motor vehicle non-contact charging device internal coil.
Background technology
The informational needs such as the charged state of motor vehicle non-contact charging device transmit between energy transmitting terminal and energy receiving terminal, and current method is realized by the mode of the PERCOM peripheral communication such as near-field communication (NFC) or GPRS.The shortcoming of this situation is that system configuration is complicated, large by external environment condition interference, poor reliability, in addition Exterior Communications System must and the control system of motor vehicle be connected, install when system configuration complexity causes electrical vehicle configurations and transform non-contact charge as and transformation difficulty very large.
Summary of the invention
The object of the present invention is to provide a kind of communication means of motor vehicle non-contact charging device internal coil, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of communication means of motor vehicle non-contact charging device internal coil, the mode of built-in communication coil signal transmission is adopted to realize the transmission of the battery status monitor signal of motor vehicle non-contact charge, thus automatically control charged state, the high frequency electric source that built-in communication coil is arranged on motor vehicle contactless charging device respectively turns the emitter in magnetic field and magnetic field and receives and turn in electric field arrangement, when motor vehicle docks to assigned position and charging device reaches setpoint distance, communicator is started working, the signal gathered by battery management system feeds back to power supply by standard traffic host-host protocol and turns high intensity light source, to control the electric energy output that electric field turns magnetic field emitting devices, ensure the charge efficiency of non-contact charger systems.
As the further scheme of the present invention: described battery management system connects communication coil, storage battery charge control circuit respectively, charging control circuit connects AC/DC rectification circuit.
Compared with prior art, the invention has the beneficial effects as follows: the advantage adopting the motor vehicle non-contact charging device of internal coil formula communication system is that system configuration is simple, not by external environmental interference, without the need to transforming the control system of motor vehicle when electrical vehicle configurations or transformation non-contact charge.
Accompanying drawing explanation
