The invention provides a hybrid power source, an energy supply system using the same and an electric automobile. The hybrid power source is provided with a plurality of first-level direct-current energy supply devices and second-level direct-current energy supply devices. The second-level energy supply devices are connected in series. The first-level energy supply devices and the second-level energy supply devices are connected through one-way or double-way DC-DC converters one by one. According to the hybrid power source, the energy supply system using the same and the electric automobile, power batteries and super capacitors serve as the first-level direct-current energy supply devices and the second-level direct-current energy supply devices, the working voltage of the DC-DC converters is lowered through multiple converters, the working frequency of the DC-DC converters can be increased, the working efficiency of the DC-DC converters is improved accordingly, and the problems that in the prior art, DC-DC converters in a hybrid power source are large in size, high in cost, low in energy conversion efficiency, large in potential fault risk and the like are solved.
