技术领域technical field
本发明涉及无线充电的技术领域,尤其是指一种无线充电设备的测试方法及系统。The present invention relates to the technical field of wireless charging, in particular to a testing method and system for a wireless charging device.
背景技术Background technique
无线充电技术因为其便捷、安全等特点成为了目前各大电动汽车生产厂家关注的新能源技术。系统能量以电网为起点,经整流和高频逆变,在线圈中得到高频交流电,从而利用激励的磁场实现能量的无线传输。Wireless charging technology has become a new energy technology that major electric vehicle manufacturers are concerned about because of its convenience and safety. The energy of the system starts from the power grid, and after rectification and high-frequency inverter, high-frequency alternating current is obtained in the coil, so that the wireless transmission of energy can be realized by using the excited magnetic field.
互操作性问题是电动汽车无线充电产业化面临的重要问题之一。电动汽车无线充电系统的互操作性可理解为当能量发射和接收线圈结构不同、能量发射和接收端补偿拓扑不同时,充电系统的输出特性。电动汽车无线充电系统具备互操作性是指当能量发射和接收线圈结构不同、能量发射和接收端补偿拓扑不同时,充电系统的输出满足一定的限值。现阶段市场上主要存在方形、DD型、DDQ型和螺线管型线圈,存在串联、并联、LCC等补偿拓扑。当线圈和补偿拓扑协同组成传输机构时,由于线圈和拓扑结构不同所带来的互操作性差异将无法保证充电系统的正常工作。上述情况带来的后果是一旦无线充电产品处于市场推广阶段,与大多数产品不具有互操作性的产品将逐步处于竞争劣势,最终被淘汰出市场。为保证产品间的互操作性,相关测试机构需要对产品进行广泛测试,但目前这方面存在难以解决的问题。The interoperability issue is one of the important issues facing the industrialization of electric vehicle wireless charging. The interoperability of the electric vehicle wireless charging system can be understood as the output characteristics of the charging system when the structure of the energy transmitting and receiving coils is different, and the compensation topology of the energy transmitting and receiving ends is different. The interoperability of the electric vehicle wireless charging system means that when the energy transmitting and receiving coil structures are different, and the energy transmitting and receiving end compensation topologies are different, the output of the charging system meets a certain limit. At this stage, there are mainly square, DD, DDQ and solenoid coils on the market, and there are compensation topologies such as series, parallel, and LCC. When the coil and compensation topology cooperate to form a transmission mechanism, the difference in interoperability due to the difference in coil and topology will not guarantee the normal operation of the charging system. The consequence of the above situation is that once wireless charging products are in the market promotion stage, products that are not interoperable with most products will gradually be at a competitive disadvantage and will eventually be eliminated from the market. In order to ensure interoperability between products, relevant testing agencies need to conduct extensive testing on products, but there are currently difficult problems in this regard.
现有测试方法的原理是对所有产品进行交互测试,为最终形成覆盖全行业产品的标准,需要对所有产品原边设备(primary assembly, GA)和副边设备(secondaryassembly, VA)互操作时的功率效率进行交叉测试。显然,测试工作量巨大且不同厂家产品并不容易获得;再者,测试时必须时刻保持强电工作状态,因此存在一定的安全隐患;另外,现有测试方法是通过传输功率和效率直接评价互操作性,由于现有方法将所有测试产品对看作二端口网络,功率效率只能描述二端口网络的整体特性,产品中不同参数对互操作性的影响很难通过该方法表示,也就无法指导产品优化设计。The principle of the existing test method is to conduct interactive tests on all products. In order to finally form a standard covering the products of the whole industry, it is necessary to interoperate between the primary assembly (GA) and the secondary assembly (VA) of all products. Power efficiency is cross tested. Obviously, the testing workload is huge and it is not easy to obtain products from different manufacturers; moreover, the test must be kept in a strong current working state at all times, so there are certain safety hazards; in addition, the existing test method is to directly evaluate mutual Operability, because the existing method regards all test product pairs as a two-port network, the power efficiency can only describe the overall characteristics of the two-port network, and the impact of different parameters in the product on interoperability is difficult to express through this method, so it Guide product optimization design.
