Title:
VEHICLE EMERGENCY CHARGING DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/096207
Kind Code:
A1
Abstract:
A vehicle battery emergency charging device comprises a first switch, a capacitor module, a second switch, a voltage booster, and a third switch. The first switch connects a battery group to a starter motor of a vehicle, the capacitor module is connected in parallel to the battery group, the second switch connects the capacitor module to the starter motor, the voltage booster boosts the voltage of the capacitor module by using the current supplied from the battery group, and the third switch connects the battery group to the capacitor module through the voltage booster. By the configuration described above, the voltage booster boosts the voltage of the battery group and supplies the boosted voltage to the capacitor module. Therefore, even when the voltage of the battery group is lower than that of the capacitor module, the capacitor module can be charged, and even when the battery group and the capacitor module are both discharged, the voltage for starting the vehicle can be supplied.
