Electronic cycle racing hybrid power control system belongs to cycle racing power control field, and to the problem that different power driven demands are different, the technical essential is the leg of for solution cycle racing difference: including composite power source management system, vehicle condition and environmental information collection system, power battery group, super capacitor and two -way DCDC converter, composite power source management system passes through the CAN bus and is connected with power battery group, two -way DCDC converter, super capacitor respectively, super capacitor is connected with two -way DCDC converter, and super capacitor is through two -way DCDC converter and the parallelly connected energy output dc bus that inserts of power battery group. The effect is: constitute by power battery group, super capacitor and two -way DCDC converter to realize a composite power source form, and, electronic cycle racing hybrid power control system, in order to select the concrete form of this composite power source, in order to realize the power supply mode that compounds, the power the leg of satisfying the cycle racing difference drives the demand.
