Super-capacitor power supply management circuit and implementation method thereof

The invention discloses a super-capacitor power supply management circuit and an implementation method thereof. The circuit comprises a charging circuit for charging the super-capacitor module and a power supply circuit. According to the design, a stable power supply can be provided when the system is powered off, thereby ensuring stable operation of a vehicle-mounted radio station and greatly reducing the failure rate. A boost circuit is used for supplying power to the system; along with the process that the super-capacitor module supplies power to the system, the voltage of the super-capacitor module is continuously reduced, the situation that the super-capacitor module cannot normally supply power to the system when the voltage is too low can be avoided, more stable power can be provided for the system through the mode, and meanwhile the use efficiency of the super-capacitor module is improved. The working efficiency of the boost chip selected by the power supply circuit is as highas 95%, the input voltage
