On-Board Powerplant - Numerical optimization of combustion engines in serial hybrid drives
Overview
Background & policy context:
Vehicles with electric drive train offer a good compromise between conventional drive concepts and all-electric vehicles regarding fuel consumption and range. They use the advantages of electrification (recuperation, electric propulsion) without being limited by the short range of today’s electric vehicles. Thus, the usage of the internal combustion engine is changed toward the combined propulsion with the electric motor or the charging of the battery. The waste heat of the engine can be used for heating the interior, which is essential for electrified vehicles.
Objectives:
These complex structures require appropriate tools to develop a customized engine concept.
The aim of the project was therefore to develop a numerical model for the optimization of combustion engines in serial hybrid drives.
Methodology:
For this purpose, a longitudinal dynamics model of the Chevrolet Volt and the Opel Ampera has been created in the simulation environment GT–SUITE. The vehicle model included the internal combustion engine, the cooling water circuit, the driver's cab and the electrified powertrain.
