Abstract
esta revelação fornece métodos e equipamentos para testes de campo de energia sem fios. é fornecido um método para gerar o teste da interoperabilidade de um transmissor de energia sem fios com um ou mais receptores de energia sem fios. o método inclui gerar um campo magnético através de uma antena de transmissão. o método inclui medir uma primeira uniformidade do campo magnético em todos os locais dentro do campo magnético em uma superfície de carregamento do transmissor de energia sem fio. o método também inclui determinar que a primeira uniformidade medida do campo magnético está dentro de uma faixa de valores em todas as localizações na superfície de carregamento do transmissor de potência sem fios. em algumas implementações, o método inclui ainda aplicar uma carga ao campo magnético, medir uma segunda uniformidade do campo magnético enquanto a carga é aplicada e determinar se a primeira uniformidade do campo magnético é substancialmente semelhante à segunda uniformidade.
