The invention provides a new energy multi-mode electric vehicle charging pile. The new energy multi-mode electric vehicle charging pile comprises a photovoltaic module, a main circuit, a control circuit, a voltage comparison unit, a topology selection circuit and an energy storage module. The main circuit is used for converting photovoltaic output into controllable output under the control of the control circuit so as to supply power to a load; the main circuit is provided with no less than two transformation topologies with different voltage gain ranges; the voltage comparison unit and the topology selection circuit acquire the output converted by the main circuit, compare the current output value with a reference value, and select the conversion topology corresponding to the voltage gain range according to the magnitude relationship between the current output value and the reference value; the energy storage module is connected with the photovoltaic module through the main circuit; and the energy storage module is used for storing photovoltaic surplus electric energy and directly supplying power to a load under a set working condition. The charging pile has three working topologies, has a wide voltage range, selects different topological structures to meet load requirements under the condition of load and input change, and has high adaptability.
