Patent ID: 10174736

Abstract:
The present invention provides an emergency starting device, including a first output end and a second output end, wherein the first output end is used for being connected to a positive electrode of an accumulator battery in an engine starting system and the second output end is used for being connected to a negative electrode of the accumulator battery; the device includes a super-capacitor, a controller and a DC-DC booster circuit, wherein the controller receives first electrical signal from the accumulator battery and electrically connects the super-capacitor and the accumulator battery to start the engine with energy stored in the super-capacitor when the first electrical signal changes suddenly, the DC-DC booster circuit increases the output voltage of the accumulator battery to charge the super-capacitor. The invention further provides an emergency starting method accordingly. By using the super-capacitor, the controller and the DC-DC booster circuit the invention fits in various severe environments and can start an engine in emergency permanently and effectively.
