Abstract

PSA Peugeot Citroën has unveiled in 2013 a new hybrid powertrain concept—Hybrid Air-described as a disruptive hybrid system that makes a major step to lower emissions and fuel economy. With this system during city driving cycle, vehicle operates in Air Mode from 60 to 80 % of the time. As thermal engine operation is resultant of this on and off mode, the alternator is mainly shut off; in consequence, the lead-acid battery has strong cycling increase and can be quickly damaged. Besides, it’s not suitable to power the electrical equipment during such a long time with only battery voltage (lower than 14 V). To fit those requirements, PSA Peugeot Citroën has developed an electrical system called “SPRESSO” performing two major functions: quick storage and energy management. It can handle with high efficiency, the charge and the discharge of a high-capacity electric double layer capacitor (EDLC), minimizing spare stored energy and makes it possible to supply electricity to all vehicle equipment during Air Mode. SPRESSO is compatible with standard 12 V architecture (alternator and lead-acid Battery) and offers a long life and cost effective electrical system to Hybrid Air equipped vehicles.
