Starting power supply device capable of reverse charging

Abstract

A starting power supply device capable of reverse charging includes a main control module, a rechargeable battery connected to the main control module, and a battery level detection module connected to the main control module and the rechargeable battery. The battery level detection module is configured to detect a battery level of the rechargeable battery to generate a battery level signal to be sent to the main control module. The main control module is configured to determine the battery level of the rechargeable battery. The rechargeable battery is connected to a car battery through a control module. Moreover, when the battery level of the rechargeable battery is lower than a preset battery level, the main control module is configured to obtain electrical energy from the car battery to charge the rechargeable battery reversely.
