Abstract

The main problem with Hybrid Electric Vehicles (HEV) is the management of batteries. We suggest to replace the batteries by an energy storage ystem made of supercapacitors on a series HEV with two traction drive. A maximum Control Structure (MCS) of such an HEV is presented to organize the control of the different subsystems. MCS is based on specific inversion rules of Energetic Macroscopic Representation (EMR). This methodology leads to a global model of the system and its deduced control. Moreover, this enable to identify precisely the maximum control for the chopper associated with the supercapacitors. The simulation of an Extra Urban Driving Cycle (EUDC) is provided.

Hybrid electric vehicle

A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system (hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies.

Hybrid vehicle

A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. In hybrid electric vehicles, for instance, the electric motor is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed.

Plug-in hybrid

A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of sports cars, commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles.
