Abstract
The present disclosure discloses an emergency starting power supply, which comprises an energy storage module, an output interface, a first detection module, a switch module and a control module. The first detection module is electrically connected to the output interface, and detects a voltage of an automotive battery through the output interface when the output interface is connected to the automotive battery. The switch module is electrically connected between the energy storage module and the output interface. The control module is electrically connected to the first detection module and the switch module, respectively. The control module is used to determine whether a voltage drop of the battery within a first preset time is greater than a preset voltage drop based on the voltage detected by the first detection module. The control module controls switch module to close to switch on the electrical connection between the energy storage module and the output interface when the voltage drop in the first preset time of the battery is greater than the preset voltage drop, so that the energy storage module provides an emergency starting current through the output interface and the ba…
