The invention discloses a method for improving efficiency of a bidirectional wireless electric power transmission system through controlling voltage ratios on two sides. The bidirectional wireless electric power efficiency transmission system efficiency improvement method can regulate voltage of the other side with voltage of one side as a standard according to parameters of resonance coils on two sides when wireless energy interaction is performed between an electric automobile and a power grid or between the electric automobiles in order to make electric energy flow efficiently on two sides. The bidirectional radio energy transmission system efficiency improvement method is not only applicable to a bidirectional electric energy transmission system with symmetric parameters, but is also applicable to an asymmetric bidirectional wireless electric energy transmission system. 本发明公开了种通过控制两侧电压比来提升双向无线电能传输系统效率的方法。该方法具备在电动汽车与电网之间或者电动汽车之间进行无线能量互动时，根据两侧谐振线圈的参数，并以某侧的电压为基准，调节另侧电压，以使得电能在两侧能够高效流动。该方法不仅适用于参数对称的双向无线电能传输系统，
