The invention provides a buck-boost charging and discharging circuit and a tool for riding instead of walk, and relates to the technical field of new energy automobiles. The system comprises a high-voltage battery, an electric driving system and a charging and discharging interface, the high-voltage battery is connected with the electric driving system; the electric driving system is connected with the charging and discharging interface; the electric driving system comprises a plurality of switches, the plurality of switches are alternately closed to control the buck-boost charge-discharge function of the buck-boost charge-discharge circuit, and the plurality of switches are configured in the electric driving system, so that random switching of a power loop from the high-voltage battery to the charge-discharge interface is realized, the normal driving function of the electric driving system can be realized, and the reliability of the electric driving system is improved. And the function of bidirectional boost-buck of the high-voltage battery to the charge-discharge interface can be realized.
