Interface to Create Driving Cycles and Load Profiles for Different Kinds of Vehicles.
With the development of the automotive industry and computer technology, the demand for the vehicle power system simulation is also growing. A good simulation model can be fast and accurate to estimate the power performance, energy demand and operational efficiency for different driving cycles and different vehicles. Based on the background, the purpose of this interface is to allow users to quickly select/create driving cycles, load profiles for different vehicles and choose the calculation approach in order to simulate the vehicle dynamic performance in the running process, the results values can be displayed and plotted by 2D&3D form through this interface.
Sizing of ICE and Lithium-ion battery for series hybrid vehicle over life cycle with battery aging
This paper presents a method to evaluate the volume and weight of the internal combustion engine (ICE) and lithium-ion battery for a series hybrid vehicle that allows to minimize the mean consumption over system life. Individual driving cycles of the car over a total distance of 100 000 km are simulated. The ICE and battery dimensions are approximated; the fuel consumption is evaluated using a general approach. Lithium-ion battery is described including capacity fading and the energy split between ICE and battery system is evaluated using an heuristic approach. Results show a decrease of mean fuel consumption down to 5.1 L/100km.
Multi Architecture Optimization of a Hybrid Electric Vehicle Using Object-Oriented Programming
This article presents an energetic macroscopic representation multi-architecture model for hybrid vehicles using object-oriented programming. This approach is successfully used to evaluate the power performance and fuel consumption of different vehicles on different driving cycles. An optimization of power source sizing (ICE, EM and Battery) and system control, based on simulation results, is carried. Different architectures are compared for given cycles and optimization of hybrid architecture will also be possible.
