According to a new energy vehicle energy recovery control device, a voltage control circuit adopts an operational amplifier AR1 to calculate the difference value between the voltage in the charging stage of a storage battery and the voltage stored in a super capacitor 1, when the difference value is negative, a triode Q2 is turned on, a coil of a relay K2 is powered on, the difference value changes the drain-source resistance value of a field-effect tube Q6, the difference value is subjected to voltage division. The voltage of the voltage dividing point is converted into PWM signals through the PWM conversion circuit, the PWM signals are added to the voltage regulating circuit to roughly regulate the voltage stored in the super capacitor 1, the PWM signals are added to the base electrode of the transistor Q3, the super capacitor 2 is controlled to charge redundant electric energy, and the voltage required in the charging stage of the storage battery is output after the voltage is rectified by the secondary coil of the transformer T1 and the diode D2 when the electric energy is insufficient. And the current enters a current control circuit and charges the storage battery after being subjected to current limiting by a resistor R16, voltage stabilization by a triode Q4 and further current limiting by a resistor R17, and stage charging can be performed according to the voltage and the current of the storage battery, so that the charging rate of the storage battery can be improved, and the service life is not influenced.
