In this article the use of supercapacitors like power supply for automotive applications is presented. The specific power of the supercapacitors and its high lifetime (1 million of cycles) makes it very attractive for the startup of the car. Unfortunately, the specific energy of this component is very low. For that this technology is associated with battery to supply the starter alternator. After the identification of the ICE torque developed at the startup, the validation of the hybrid supply interest is proved by the simulation of the system using Matlab-Simulink software.
