Electrified vehicles can be classified with hybrid electric vehicles, battery electric vehicles and fuel cell electric vehicles. These vehicles have two more than energy converters which are the part of a powertrain. It is particularly difficult to estimate the power of hybrid electric vehicles due to two different energy converters with different power characteristics. Therefore, a new power concept for these vehicles is needed. The vehicle power as the new concept for solving this problem was defined in this study. The test method and the procedure were made a development in this study. Four electrified vehicles with different electric fraction were used to validate the method. Two percentage of COV was suggested as a criterion for the maximum vehicles power based on the previous studies. The repeatability of this method was within ±2 per cent for the maximum vehicle power and within ±5 per cent for the vehicle speed at maximum vehicle power.

As the environment and fuel economy issue become more important than last 10 years, The significance of Electrified Vehicle has come to the fore worldwide. First of all, Because Battery is very significant among many kinds of Electrified vehicle components, Medium and Large size battery suited for Electrified Vehicle will get more of importance. The objective of this paper is to develop an impact analysis tool for future battery technology of Electrified vehicle. There are two key factors in developing an impact analysis tool. One is making detailed vehicle model by using Autonomie developed in Argonne National Laboratory. The other is building the Large-scale Simulation environment by using vehicle model compiling and parallel computing. By utilizing this analysis platform, It is expected to analyze about 1,000,000 vehicle simulation models per day.

WorldAutoSteel launched Phase 2 of its FutureSteelVehicle program with the aim to show automakers how latest and future steel grades & technologies can provide light body structures for electrified vehicles. The objective was to develop detailed design concepts and fully optimise a radically different steel body structure for a compact battery electric vehicle in production in the 2015-2020 timeframe. This paper discloses the final outcomes of the Phase 2 development, detailing steel body structure concepts for the aforementioned vehicles that achieved the aggressive mass target of 190 ㎏, while meeting 2015-2020 crash performance objectives as well as total life cycle greenhouse gas emissions targets, NVH and stiffness. This is achieved using advanced & ultra high-strength steels, engineering design optimization and advanced steel technologies.

자동차기술 패러다임 변화 대응을 위한 디자인융합전략의 시사점 고찰
구상(Koo, Sang) 한국전시산업융합연구원 2019 한국과학예술융합학회 Vol.37 No.3
본 연구는 오늘날의 자동차기술이 자율주행기술과 전동화 차량 개발의 진전, 공유경제 개념의 등장으로 인해 기존의 기계제조업이었던 자동차기술의 특성이 크게 변화될 것을 요구된다는 배경에서 시작되었다. 본 연구의 목적은 이러한 자동차기술의 급격한 변화에 따른 자동차디자인에서의 전략이 향후에 어떤 변화를 맞게 될지를 살펴서, 보다 거시적인 차량개발전략 수립 방법으로써의 디자인융합전략에 대한 시사점을 찾는 것이다. 따라서 본 논문은 향후의 자동차산업의 변화에 의한 디자인 융합전략을 고찰하였다. 본 연구의 결과 및 내용은 다음과 같다. 첫째, 서비스 개념의 강화로 완성차 제조사 브랜드보다는 이동이나 공유 서비스 제공 회사가 어디인가가 오히려 중요해질 것으로 보인다. 둘째, 다른 한편으로는 개인소유를 중시하는 차량의 개발에서는 오히려 개별 차량의 스타일 특성이나 기능적 차별성을 강조하는 상반된 디자인 전략이 유효할 것으로 보인다. 이는 현재의 고급 브랜드 전략과 배치되는 현상으로 보인다. 이러한 연구 결과를 바탕으로 향후에 모빌리티 서비스나 차량공유 서비스가 확대되고 진전됨에 따라, 서비스 제공 형태에 따른 디자인 차별화 방법은 현재의 대중 브랜드와 프리미엄 브랜드에서 볼 수 있는 것과는 오히려 상반된 방향으로 진전될 수 있다는 결론을 얻을 수 있었다. This study began with as a background of the study, today’s automotive industry has been reviewed to justify totally different aspect to the past as the newly industrialized countries got higher ranks in annual global production volume. Also are demanding in its character change the automotive technology from the machinery production industry with escalating autonomous driving technology, electrifying and revealing concept of sharing economy. This study is purposed to get implications for creating automobile developing strategy of design convergence as a macroscopic method through reviewing automotive design strategy changes caused by rapid automotive technology changes. Therefore, firstly it can be predicted that the brand of the service provider who controls mobility or vehicle sharing service may have more importance than an individual brand of vehicle manufacturer in the future with more service oriented market trends with this study; secondly it may be implied either that the opposite strategy with more unique style characteristics or functional specialties might be effective for strategically reasons in developing vehicles oriented for personal use. Those seem that is to be reversed direction of brand strategy for the current luxury or premium marketing’s. Therefore it has been implied that the design differentiation strategy for mobility or vehicle sharing service provider differ from the design strategies for public brands and premium brands as the service oriented automotive industry paradigm escalated for the conclusion.
Electric Vehicle Architecture Design Based on Database
서권희,문진규 한국자동차공학회 2024 International journal of automotive technology Vol.25 No.2
The purpose of this study is to extend the mileage by improving the effi ciency of the electric vehicle (EV) driving and thermalmanagement system (TMS). The powertrain system and the TMS must be considered simultaneously from the architecturestage as complementary systems to maintain the driving performance of the EV. This paper proposes an EV architecturaldesign method and a multi-physical EV modeling technique. The main components of the EV are standardized diff erentlyfrom those of the internal combustion engine (ICE) vehicle, and the TMS is designed by thermal system confi guration. Therefore, instead of the traditional continuous variable-based design methodology, optimal combination design based on thecomponent database (DB) and the confi guration plot presents the combinational design method. The performance of an EVvaries depending on the performance of driving components and TMS, and weather. This paper presents a Modelica-basedvehicle modeling technique to integrate multiple physical phenomena. Finally, we implemented an automated design usingthe optimal combination design method and the multi-physical integrated vehicle model design framework. The design of theC-segment EV was carried out to review the validity of the proposed method. 2880 laboratories were planned and designedusing design variables with 10 levels of mixing. As a result of the design, we have confi rmed that the mileage increases by5% compared to the previous one in NEDC mode.
