A protection device for a supercapacitor of a power supply system of vehicle, the power supply system including a rechargeable battery, the supercapacitor, and a power generator. The protection device contains a first voltage detector, a second voltage detector, a temperature detector, a processing unit, a control unit, a communication unit, and an alarm. The first voltage detector is coupled with the rechargeable battery to detect and send a voltage value of the rechargeable battery to the processing unit. The second voltage detector is coupled with the supercapacitor to detect and send a voltage value of the supercapacitor to the processing unit. The temperature detector is coupled with the supercapacitor to detect and send a temperature value of the supercapacitor to the processing unit. The control unit includes a first transistor and a second transistor which are connected in series, and the first transistor and the second transistor are Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET).
