[0003] The test scheme of the traditional wireless charging system mainly uses discrete instruments for limited measurement. In order to test the efficiency of the wireless charging system under the alignment and misalignment of the transmitting coil and the receiving coil, the relative position of the coil is adjusted manually, and then the wireless charging process is carried out. Testing, this method is not only inefficient, but also cannot realize the development and testing of some advanced charging control program

The invention relates to a testing system for electric vehicle's wireless power charging system, comprising a control and measurement system, a receiving system, an emitting system and a mechanical platform. The mechanical platform is provided with an emitting coil and a receiving coil that are matched with each other. The control and measurement system is connected with the receiving system, the emitting system and the mechanical platform respectively. The emitting system is connected with the emitting coil; the receiving system is connected with the receiving coil; the emitting system outputs power to the emitting coil, converts it into electromagnetic power and transmits it to the receiving coil. The receiving coil converts the electromagnetic power into electric power and transmits it to the receiving system. The control and measurement system outputs a control signal to the mechanical platform and adjusts the relative position of the emitting coil to the receiving coil. The control and measurement system measures the voltage signals and the current signals of the emitting system and the receiving system respectively; and based on the voltage signals and the current signals, it is possible to conduct testing for an electric vehicle's wireless power charging system. The testing system of the invention is capable of making testing more automatic and increasing the testing efficiency.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a test system for a wireless charging system of an electric vehicle. Background technique [0002] Wireless charging has the characteristics of good safety, high degree of automation, no mechanical contact, and long service life of parts. It is one of the development directions of electric vehicle charging technology. The wireless charging method of electric vehicles is to use electromagnetic induction or electromagnetic vibration to realize the non-contact transmission of electric energy through the transmitting coil of the transmitting system and the receiving coil of the receiving system, so as to charge the battery of the electric vehicle. In the development process of the electric vehicle wireless charging system, it is necessary to test the wireless charging system, collect relevant data during the charging process in real time, and process and analyze them.
