A rescue device (1) of boosting 24 volts to a supercapacitor for vehicle(s) and a method of controlling the same, the rescue device (1) is electrically connected a circuit system in which a vehicle battery pack (10) and a vehicle electrical control device (13) are connected parallelly. The rescue device (1) includes a booster module (14), a supercapacitor module (15), a first relay (16), a second relay (17), a third relay (18), a first positive-electrode circuit (21), a second positive-electrode circuit (22), a negative-electrode circuit (23), and a rescue control module (30). The rescue control module (30) acquires a power from the vehicle battery pack (10) via the second positive-electrode circuit (22) based on a low voltage of the vehicle battery pack (10) and boosts an output voltage to charge the supercapacitor module (15) via the booster module (14). After the supercapacitor module (15) is rechargeable completely, it supplies the power via the first positive-electrode circuit (21) to start the vehicle electrical control device (13), thus rescuing the vehicle.
