The invention provides a storage battery charging system of a gasoline-electric hybrid vehicle. The storage battery charging system comprises a voltage-stabilized power supply, a charger integrated circuit module, a microprocessor and a temperature sensor. According to the invention, an alternating current power supply is converted into a stable and reliable direct current charging power supply through the voltage-stabilized power supply; the temperature sensor monitors a temperature signal of a storage battery pack in real time, processes the temperature signal through the charger integrated circuit module and feeds the temperature signal back to the microprocessor; the charger integrated circuit module monitors a charging voltage and current signal of the storage battery pack in real time and feeds the charging voltage and current signal back to the microprocessor; the microprocessor calculates, processes and analyzes the collected signal and sends out a control signal; and the charger integrated circuit module adjusts the magnitude of the output current of the voltage-stabilized power supply and adjusts the charging current of the storage battery pack. With the system, the state of storage batteries can be monitored in real time, the charging current and voltage are adjusted fully according to the charging characteristics of the storage batteries, constant-voltage floating charging is carried out in the later period of charging, the storage battery pack is effectively prevented from being overcharged, and the service life of the battery is prolonged to the maximum extent.
