The invention discloses an integrated low-voltage energy storage power supply system for a vehicle. The integrated low-voltage energy storage power supply system comprises a storage battery; a power supply main switch, the input end of the power supply main switch being connected with the positive electrode of the storage battery, and the negative electrode of the storage battery being the whole vehicle common ground; a charging relay, the input end of the charging relay being connected with the output end of the power supply main switch, and the output end being grounded; a current-limiting resistor, the input end of the current-limiting resistor being connected with the output end of the charging relay; a super capacitor module, formed by connecting a plurality of super capacitors in series and in parallel; a parallel relay; and a starter, the output end of the starter being connected with a whole vehicle engine starter. The parallel relay enables the output end of the power supply main switch to be connected in parallel with the positive electrode of the super capacitor module. The input end of the starter is connected with the output end of the current-limiting resistor, the output end of the parallel relay and the positive electrode end of the super capacitor module. Charging current-limiting control can be realized, and the starting success rate is improved. The invention further provides a control method of the integrated low-voltage energy storage power supply system for the vehicle.
