A Simple Technique for Optimal Selection of Degree of Hybridization (DOH) in Parallel Passenger Hybrid Cars

et al. 2015

In this paper, a simple but efficient Non-dominated Sorting Genetic Algorithm (NSGA) II based technique is proposed for optimizing the Degree of Hybridization (DOH) in parallel passenger hybrid cars. The authors' objective is to improve performance, maximize fuel economy and at the same time, minimize mass and emissions as much as possible, by optimal selection of DOH. The NSGA-II, which is a multi-objective optimization algorithm, is applied to optimize this multiple objective problem. The ADvanced VehIcle SimulatOR (ADVISOR) software is used as simulation tool. To validate high efficiency of proposed methodology, necessary simulations have been carried out on a small-size test car. The results indicates that the proposed methodology is very fast and efficient and can be well applied to any other types of Hybrid Electric Vehicles (HEVs).Key words: Degree of Hybridization (DOH), Electric motor, Emissions, Fuel economy, Performance Jednostavna metoda za optimalan odabir stupnja hibridizacije (DOH) u paralelnim putničkim hibridnim automobilima. U radu je predložena jednostavna i efikasna metoda zasnovana na nedominirano-sortirajućem genetičkom algoritmu (NSGA) II u svrhu optimiranja stupnja hibridizacije (DOH) u paralelnim putničkim hibridnim automobilima. Cilj je unaprijediti performanse, maksimizirati ekonomičnost goriva te istovremeno minimizirati emisiju koliko god je moguće uz optimalni odabir DOH. NSGA-II algoritam, koji spada u višekriterijske optimizacijske algoritme, korišten je za optimiranje problema s više ciljeva. Napredni simulator vozila (ADVISOR softver) korišten je kao simulacijski alat. Simulacije su provedene na umanjenom testnom vozilu kako bi se validirala visoka efikasnost predložene metodologije. Rezultati ukazuju da je predložena metoda vrlo brza i efikasna te ju je moguće primijeniti i na bilo koji drugi tip hibridnog električnog vozila (HEV).

This paper deals with the weight reduction design of In-Wheel type motor for high power density.Accordingly, characteristic and weight of the motor caused by modifying reduction gear ratio are examined.Weight of motor is minimized by modulating the ratio of stack length and external diameter of stator. Then, In-Wheel motor geometry based on the prototype is optimized to get the determined parameters using response surface methodology (RSM) and Finite Element Method (FEM). Optimal design of core usage in rotor is conducted for minimizing weight of motor which has identical characteristic to the prototype.Characteristic analysis is conducted by using equivalent circuit analysis of PM type motor. Through the presented weight of In-Wheel type motor, total weight is reduced to 25%, and power density is improved to 57% from the prototype motor.

Abstract. The paper deals with the study of the motorization for an electric scooter. The motivation of this study is firstly introduced. Next, the application is defined: it is intended to propose a pure electrical traction system for a light electric vehicle, meaning an electric scooter). A short description of the design will introduce the main parameters of the electrical drive system and three topologies of electrical machine will be evaluated. The optimization of the best suited variant will be made based on a gradient type optimization algorithm. Numerical computation, by means of finite element method, will confirm the analytical obtained results, emphasizing the main achievements, performances and drawbacks of the electrical traction system. These performances are evaluated on test bench for validation.
