Electric vehicles have great potential to reduce gasoline imports, and thus preventing the outflow of currency from the country, reduce dependency on foreign countries, increase energy security, and most importantly reduce environmental pollution in large and polluted cities, which is a serious threat to the health of their residents. In this regard, Iran is moving toward greater use of this type of cars. But the main problem is its expensive energy storage system that if properly designed, can prevent the extra costs. This article assumes that gas stations in suburban roads due to infrastructures, be considered as charging stations. Due to the distances between gas stations, the criterion to determine the amount of energy required to reach the destination can be derived in KWh. The amount of power required will be approved based on the drive cycles, including Tehran TEH_CYC driving cycle and PNGV tests. All this simulations will be done in the toolbox ADVISOR in MATLAB and eventually the battery will be offered for each province.

Özet: Bu çalışma da otomobillerdeki yakıt pili sistemleri, ADVISOR programı kullanılarak modellenmiş ve yapılan modeller karşılaştırılarak analiz edilmiştir. Yakıt pili sistemleri tüm taşıt sistemi içerisinde kritik önem taşıyan ana unsurlardandır. Bu nedenle bir taşıtta yakıt pili sisteminin; tesis edilmesinden önce, sisteme uyumluluğunun analizinin yapılması, maliyet ve güvenlik bakımından oldukça önemlidir. Amerikan Ulusal Yenilenebilir Enerji Laboratuvarı (NREL) tarafından geliştirilen ADVISOR programı bu tür sistemlerin mukayesesinin yapılmasını sağlamaktadır. Bu makalede de özellikle bu programın nasıl kullanılacağı örnek bir uygulama ile tanıtılmakta, yakıt pili çeşitleri karşılaştırılarak elde edilen sonuçlar değerlendirilmektedir. Abstract: In this study, automotive fuel cell systems are simulated by using ADVISOR program and comparatively analyzed with a case study. Full cell system of vehicles is the most important part of the entire system. Therefore, fuel cell system of the vehicle should to be tested with software before its construction due to cost and safety issue. ADVISOR program developed by American National Renewable Energy Laboratory (NREL) is widely used for simulation of the vehicle systems as mentioned in literature. ADVISOR program is introduced with an application, and the obtained results are evaluated by comparing kind of fuel cell in this article as well.

Four “hot spots” to engage with advisory practice in politics are presented. Any approach should be aware of a rich legacy and long history of advisers and political decision-makers. Secondly, the predisposition and role of advice-takers is key to understanding advice. A third concern are the rivalries between advice types of and advisers, particularly conflicts between political and policy advisers. Fourthly, the identity of political advice is changing with the advent of advocates who insist that their counsel may be interest-driven but nevertheless good advice, too.
DEUTSCH Vier Aspekte der Beratungspraxis in der Politik werden thematisiert. Jede Annäherung sollte sich des reichen Erbes und der langen Geschichte von Beratern und politischen Entscheidungsträgern bewusst sein. Zweitens sind die Einstellungen und Rollen der Ratnehmer ein Schlüssel zum Verständnis der Beratung. Ein dritter Aspekt sind Reivalitäten zwischen Beratungs- und Beratertypen, insbesondere Konflikte zwischen prozessualen und inhaltlichen Politikberatern. Viertens verändert sich die Identität der Politikberatung durch die Ankunft von Interessenvertretern, die darauf bestehen, dass ihr Rat zwar interessengetrieben ist, aber doch gute Politikberatung sein kann.

Abstract. This paper presents a HEV modelling and simulation that incorporates both energy management system (EMS) controller and vehicle dynamics controller (VDC) which was converted from a conventional vehicle. Prior to building the HEV model, a vehicle dynamics experiment was conducted purposely to validate to base model created in ADAMS/Car. The base and HEV vehicle model was built in ADAMS/Car whilst the controller which includes the EMS and VDC was built in MATLAB/Simulink by utilising the Fuzzy Logic Controller (FLC). The HEV model and its controllers were analyzed for its performance and characteristics using co-simulation environment between ADAMS/Car and MATLAB/Simulink. Initially, separate sets of simulations were performed to test the operations of the vehicle dynamic controller and energy management controller. The model was found to have improved in handling characteristics and the results from EMS controller was found to be in close agreement with the results of the m...

A study on plug-in hybrid electric recreational boat (PHERB) powertrain with a special energy management strategy modeling and analysis was presented in this paper. Firstly, the boat components are sized to meet the expected power and energy requirements through a power flow analysis. Then, the model is tested numerically in the MATLAB/SIMULINK environment using the existing driving cycle. The accuracy of the model is verified by a comparison of the component between the simulation results from PHERB and advanced vehicle simulator (ADVISOR) software. The simulation results of component, fuel economy and emission of PHERB and hybrid electric vehicle models in ADVISOR are compared.
