[0051] The battery module 3 is connected to the supercapacitor module 1 and the mode control module 2, and includes a battery 31. When the vehicle emergency starting device is turned on and in the first mode, the supercapacitor 11 is charged by the battery 31.

[0052] When the vehicle emergency starting device is turned on and is in the second mode, and at the same time the vehicle emergency starting device is connected to the vehicle via the electrical clamp, the vehicle emergency starting device provides power for starting the vehicle.

[0053] Specifically, the supercapacitor 11 cannot store sufficient electrical energy for a long time due to self-discharge, while the battery 31 can store more electrical energy for a long time.

[0054] Furthermore, the current required to start a vehicle is usually above 100 to 200 amperes, and the battery 31 cannot output a sufficiently large current, while the supercapacitor 11 can release a very large current in an instant to start the vehicle. Therefore, the combined use of the supercapacitor 11 and the battery 31 can enable the vehicle emergency starting device to be used for a long time without being charged without affecting normal use.

[0063] When the real-time power level does not reach the power threshold, the judgment unit 22 switches the vehicle emergency start device to the first mode;

[0064] When the real-time power level reaches the power threshold, the judgment unit 22 switches the vehicle emergency starting device to the second mode.

[0065] Furthermore, the monitoring unit 21 detects the real-time power level of the supercapacitor 11 and outputs the real-time power level to the determination unit 22 .

[0066] Furthermore, the judgment unit 22 controls the vehicle emergency starting device to switch modes according to the power threshold.

[0067] Specifically, the power threshold is a full-load power value of the supercapacitor 11 .

[0068] In a preferred embodiment, the battery module 3 further includes:

[0076] The output module 5 is connected to the battery module 3 and is used to charge an external device connected to the output module 5 using the battery module 3;

[0077] The lighting module 6 is connected to the battery module 3 and is used to provide LED lighting function under the power provided by the battery module 3.

[0078] Specifically, the external input module 4 can be a vehicle power supply, a solar panel, a mobile power supply, a home charger, etc.

[0085] Specifically, if the power display unit 71 is a display screen, the display screen displays the real-time power levels of the capacitor module 1 and the battery module 3 to the user in the form of text, images, or voice.

[0086] Specifically, if the power display unit 71 is a multi-color tower lamp, the real-time power of the capacitor module 1 and the battery module 3 are displayed by a multi-color tower lamp respectively. As the power decreases, the lighting height of the multi-color tower lamp gradually decreases, and the light color changes from green to red to display the real-time power.
