4 - Which HEV is used for Trucks? - 4 Series HEV only operated to charge batteries is operated at its maximum efficiency point More conversion stages. ESS PE1 PE2 Fuel Series EM1 EM2 Trans. Parallel HEV ESS Fuel Both and motor connected to transmission. PE EM2 Trans. Less conversion stages and higher efficiency. Parallel

5 Series-Parallel HEVs: - Which HEV is used for Trucks? - 5 flexible to operate in either series or parallel mode. more efficient than series or parallel more complex due to Power Split Device (PSD) ESS PE1 PE2 Fuel EM1 EM2 P S D Series - Parallel Trans. Series-Parallel Heavy-duty HEVs Limitation for the PSD: mechanical constraints and space reduction (simple planetary gear is not capable)

6 - Context - 6 Heavy-Duty HEV Series or Parallel (Mack / Volvo / OSHKOSH, etc.) No Series-Parallel (Limitation of PSD) New PSD proposed by NEXTER SYSTEM [Patent] (Double Planetary Geartrain)

7 - Aim - 7 Study of heavy-duty series-parallel HEVs using the new PSD for military applications (strong power constraints) for civil applications (strong energy constraints) Garbage Truck Military Truck

8 - ARCHYBALD: Partners - 8 L2EP: Formalism of modeling, synthesis of control IFSTTAR: Storage system FEMTO-ST: Design of the electrical machines BATSCAP: Development, production and selling of batteries and scaps NEXTER SYSTEMS (coordinator): Skills in electrical and mechanical transmission

23 - Conclusion - 23 The EMR proved: global capabilities to represent the complex systems ; providing complete information as its functional perspectives ; to easily deduce the local control structure of the system. ARCHYBALD Project: first study about Series-Parallel HEV ; complex control (4 Shafts for 2 State Variables) ; developed common program for 2 different applications.

24 - Future work - 24 verify the proposed EMS through experimentation
