Charging converter of electric motorcycle

The utility model belongs to the technical field of converters, particularly relates to a charging converter for an electric motorcycle, and aims to solve the problem that charging current is too large due to constant-voltage charging when the voltage of a starting battery is low and under the extreme condition of more undervoltage, which is very unfavorable for the service life and safety of a small battery. The circuit comprises a single-chip microcomputer SCM, the single-chip microcomputer SCM is connected with a voltage sensor V and a switch element T, the switch element T is connected with a lithium battery A, a negative electrode of a diode D and one end of an inductor L, and the other end of the inductor L is connected in parallel with a capacitor C, electric equipment Y, a starting battery S and one end of the voltage sensor V. The charging voltage is intelligently adjusted, so that the charging current is controlled within the most reasonable range, the service life of the starting battery can be bet
