The embodiment of the invention provides an ultra-wide output voltage charging module. The ultra-wide output voltage charging module comprises an LLC resonant circuit and a buck-boost converter, the output end of the LLC resonant circuit is connected with the input end of the buck-boost converter. The LLC resonant circuit comprises a switch assembly, two resonant cavities and two transformers. The connection relation between the two resonant cavities and the two transformers is adjusted by controlling the conduction number of switches in the switch assembly, so that the resonant structure of the LLC resonant circuit is adjusted, and the transformation coefficient of the buck-boost converter is controlled, so that the transformation range of the buck-boost converter is adjusted. Through the combination of the two adjusting modes, the large-range adjustment of the voltage output range of the charging module can be realized, so that the ultra-wide output voltage range is realized.
