The invention discloses a vehicle energy management method and system, electronic equipment and a readable storage medium. The method comprises the steps that a controller obtains the required power, the required voltage and the required current of a driving motor and the maximum power, the maximum voltage and the maximum current which can be output by a power battery; and under the conditions that the required power is greater than the maximum power, the required voltage is greater than the maximum voltage and the required current is greater than the maximum current, the controller sends a first control signal to the silicon carbide boost inverter, sends a second control signal to the super capacitor and sends a third control signal to the power battery. And the silicon carbide boost inverter boosts the voltage of the driving motor according to the first control signal, so that the boosted voltage reaches the required voltage. The super capacitor provides driving current for the driving motor through the silicon carbide boost inverter according to the second control signal and the power battery provides driving current for the driving motor according to the third control signal. According to the embodiment of the invention, the endurance mileage and acceleration performance of the new energy automobile are improved.
