The invention discloses a wireless charging transmitting terminal adjusting method. The method comprises the following steps: presetting a power battery charging voltage range and an inverter input voltage minimum value; a power battery charging voltage value and an inverter input voltage value are obtained, and a gain voltage value is obtained; obtaining a minimum segment voltage value and a maximum segment voltage value according to the gain voltage value; the minimum value, the minimum segment voltage value and the maximum segment voltage value of the input voltage of the inverter are all in a preset power battery charging voltage range and are divided into four sections; the charging voltage value of the power battery is matched with the four intervals, and corresponding adjustment is carried out if the charging voltage value falls into different intervals; the common mode is that at most two of the phase of the transmitting end, the control frequency and the inverter input voltage are selected for adjustment. The adjustment of the three values is easy to operate, safe and reliable, and the whole method presets the charging voltage range of the fixed power battery, and can meet the requirements of all electric vehicles in the market for wireless charging of the electric vehicles.
