DC-DC converter for series energy storage and electric vehicle

The invention relates to a DC-DC converter for series energy storage and an electric vehicle. The DC-DC converter for series energy storage comprises a first power battery, a second power battery, a first high-frequency inverter bridge module, a second high-frequency inverter bridge module, a control module and the like. The first high-frequency inverter bridge module is used for inverting direct current output by the first power battery into first high-frequency alternating current and outputting the first high-frequency alternating current under the control of the control module; the second high-frequency inverter bridge module is used for inverting the direct current output by the second power battery into a second high-frequency alternating current and outputting the second high-frequency alternating current under the control of the control module; the high-frequency transformer is used for fusing, electrically isolating and transforming the first high-frequency alternating current and the second high-fre
