綠色交通:電動汽車與充電站

   未來的交通都將是綠色的,這意味著需要研究各種替代方案,以取代傳統的汽油車輛。另一個挑戰是使這類替代品變得更輕,提高強度,提高效率,同時能夠批量生產,以滿足需求。目前的工業趨勢趨向于發展電動汽車,但適當的基礎設施為這些車輛充電也同樣重要。TriovisionCompositeTechnologies與其合作伙伴Lush Motors和Winlet一起提出了一種優秀的解決方案,使用先進的復合材料為充電站制造一輛電動汽車和一臺垂直軸風力渦輪機。

  以綠色的方式工作是一個小時的需要,因為隨著變暖,正面臨許多挑戰。TriovisionCompositeTechnologies是一家總部位于印度的公司,在工程、模具、原型制造和制造方面具有核心競爭力,它一直處于先進復合材料的前沿,它與Lush Motors和Winlet密切合作解決這些問題。結合Lush汽車的智能城市多功能車,風車的垂直軸風力發電機充電站和Triovision的復合知識,這個項目是無法完成的。
  智能城市多用途車
 


 
  茂盛汽車公司是一家總部位于印度的汽車公司,專注于綠色能源汽車的開發。使用兩輪車在城市通勤的人們面臨著諸如惡劣的環境、污染和健康問題,以及由于交通擁堵而產生的不適當的座位問題。為了滿足日益增長的汽車需求,專門針對城市的通勤,該公司提出了三輪車和兩座電動汽車的概念。獨特的設計解決了這些問題,因為車輛是緊湊的,可以運行在任何交通,是完全封閉與天氣保護,并具有先進的功能,如觸摸屏,應用程序控制和手指掃描選項。對于傳統的金屬方法來說,設計是復雜的,復合材料在迅速將概念轉化為運行模型方面起著重要作用。所有的車輛部件都是從上半身、地板、儀表板、側后視鏡和座椅開始由復合材料制成的。該機構使用的環氧樹脂系統與納米基礎的添加劑,提供優異的性能,如減輕重量,高強度和良好的火災和煙霧性能。減輕重量在汽車部門是必不可少的,以實現燃料效率,并反過來,大大降低運行成本。
  TrioVision在設計、電子和軟件開發的各個方面設計了這個產品,并生產了一個正在運行的原型,現在可以進行系列制造了。采用樹脂轉移成型工藝,兩邊均有良好的光潔度。由于該公司采用了模具內加熱概念的創新分離工具,汽車的主體,這是一個具有挑戰性的部件,容易制造,為高吞吐量的連續制造鋪平了道路。傳統填料也是一個挑戰性的問題,在填充過程中,由于粘度的考慮,但該公司的填料系統在強度和火災和煙霧性能方面取得了很好的效果。復合材料的使用極大地提高了汽車內的整體空間包絡,而傳統的方法是縮小內殼與外殼之間的間隙,以減少整體傳熱。該車輛也有一個獨特的門機制,其中門是旋轉在一個樞軸點,以提供好的優勢,城市通勤時,車輛停在緊湊型空間。這是只有通過使用工程復合材料,因為門的重量是重要的,因為整個重量必須通過一個非中心點,其中一個巨大的負荷施加在電機上,試圖旋轉。由于復合材料的使用,這種作用是迅速而精確的。
  “當這輛車終于站在我們面前時,我們簡直不敢相信它和我們想到的概念是一樣的。”Lush的席執行官說。
  混合電力系統
 


 
  溫得樂是一家基于美國的能源技術和解決方案公司,主要致力于無線電信、wi-fi網狀網絡、電動汽車充電站、安全和監視、住宅和商業及其他分布式混合動力解決方案市場的低千瓦/分散可再生能源發電系統。該公司的業務僅包括與其混合動力系統解決方案的開發和商業化直接相關的活動和相關產品,如集成的PowerTower?,以及作為可再生網格?解決方案一部分的電動汽車充電站和wi-fi網狀網絡在內的hps和智能和動態能源尋址系統(IDEA?)的各種實現,以及作為微型電網能源解決方案的骨干。風帶公司正與TrioVision合作,將其垂直軸風力渦輪機(VAWT)商業化并進一步發展,其基礎是專有的Savonius拖曳驅動的風帶?機翼系統。
  VAWT的主要要求是能夠在低風速下運行。這只有通過使用工程復合材料來減輕重量和增加強度才有可能。該VAWT獨特的設計,使它非常有效地捕獲能源在低風速和產生良好的輸出。該刀片是使用樹脂轉移模塑與環氧樹脂為基礎的系統,以及在模內加熱系統,可以支持串行制造。減輕重量是一個具有挑戰性的設計方面,因為渦輪機可以暴露在沙塵暴和臺風。采用TrioVision公司的納米填充技術,其材料性能較差。整體減重的葉片重量對設計有很大的影響,給出了降低機組整體結構的可能性。溫得樂HPS的一些應用包括汽車、農業、手機塔、微型電網、wi-fi網絡、住宅和商業建筑、安全和監視市場。
  電動汽車風車充電站
  電動汽車工業目前面臨的主要挑戰是廣泛使用它們所需的基礎設施。風車獨特的混合動力系統目前正在解決這些問題,以提供100%的可再生充電站給Lush汽車SUMV。這些充電站可以放置在任何地方,甚至在偏遠的地方,這促進了電動汽車的使用,不僅在城市通勤,而且在城市以外的旅行。這將徹底改變汽車部門的運作方式,終所有加油站、超市停車場、公司辦公室或私人住宅都可以轉換為充電站。
  復合材料的使用正在迅速增長,而許多部門正在試圖改變他們的思維方式,以利用這些材料可以提供的關鍵利益。在這兩個項目中使用它們(用于SUMV的Lush Motors和用于VAWM的風帶)極大地受益于終產品。

  The future of transportation is all set to be green, which means various alternatives need to be investigated to replac traditional gasoline vehicles. Another challenge is to make such alternatives lighter with improved strength for better efficiency, and at the same time, being able to mass produce them to meet the demand. The current industrial trends converge towards the development of electric vehicles, but proper infrastructure to charge the vehicles is just as important. TrioVision Composite Technologies, along with its partner companies Lush Motors and Windstrip, have come forward with an excellent solution using advanced composites to manufacture an electric vehicle and a vertical-axis wind turbine for a charging station.
  Working in a green way is the need of the hour as the world is facing many challenges with global warming. TrioVision Composite Technologies, an Indian-based company with core competences in engineering, tooling, prototyping and manufacturing and which has been at the forefront of advanced composites, worked closely with Lush Motors and Windstrip to address these issues. Combining Lush Motors’ smart urban utility vehicle, Windstrip’s vertical-axis wind turbine charging station and Triovision’s composites knowledge, the project couldn’t be more accomplished.
  Smart urban utility vehicle
  Fig. 1- Smart urban utility vehicle by Lush Motors
  Lush Motors is an Indian-based automotive company that focuses on the development of green-energy vehicles. People using two-wheelers for city commuting face challenges such as a harsh environment, pollution and health concerns with improper seating due to traffic congestions. To address the growing demand for vehicles specifically targeting city-based commuting, the company came up with the concept of a three-wheeler and two-seater electric vehicle. The unique design addresses these issues as the vehicle is compact in size and can run across any traffic, is totally enclosed with weather protection and has advanced features like a touch screen, app control and finger scanning options. The design was complex for a traditional metal approach and composites played a major role in quickly turning out the concept into a running model. All the vehicle parts are made of composites starting from the upper body, floor, dash, side mirrors and seats. The body uses an epoxy resin system with nano-based additives that provides excellent properties like reduced weight, high strength and good fire and smoke properties. Weight reduction is essential in the automotive segment to achieve fuel efficiency and, in turn, significantly reduce running costs.
  TrioVision engineered this product in all aspects of design, electronics and software development and produced a running prototype that is now ready for serial manufacturing. The resin transfer moulding process was used, offering good finish on both sides. With the company’s innovative split tooling using an in-mould heating concept, the main body of the vehicle, which was a challenging component, was manufactured easily, paving the way for serial manufacturing with a high throughput. Traditional fillers were also a challenging issue during the filling process due to viscosity concerns, but the company’s filler system gave good results in terms of strength along with fire and smoke properties. The use of composites helped tremendously in increasing the overall space envelope inside the car, wheras the traditional approach was addressed with a reduced gap between the inner and outer shell to reduce the overall heat transfer. The vehicle also has a unique door mechanism wher the door is swivelled up across a pivot point to offer the best advantage of city commuting when the vehicle is parked in tight spaces. This was only possible through the use of engineered composites as the door weight is of utmost importance since the entire weight must swivel across an off-centric point wher an enormous load is applied on the motor that is trying to rotate. Thanks to the use of composite materials, the action is swift and precise.
  “When the vehicle finally stood in front of us, we couldn’t believe our eyes that it was the same as the concept we thought of”, said Lush’s CEO.
  Hybrid power system
  Fig. 2- Windstrip’s vertical-axis wind turbine charging station
  Windstrip is a US-based energy technology and solutions company primarily focused on low-kilowatt/decentralized renewable energy generation systems for wireless telecommunications, wi-fi mesh networks, electrical vehicle charging stations, security and surveillance, residential and commercial and other distributed hybrid power solutions markets. The company’s operations solely consist of activities directly related to the development and commercialization of its hybrid power system (HPS) solution and related products, such as the integrated PowerTower?, and various implementations of the HPS and Intelligent & Dynamic Energy Addressing system (IDEAs?), including electric vehicle charging stations and wi-fi mesh networks, as part of the Renewable Mesh? solution, and as the backbone in micro-grid energy solutions. Windstrip is working with TrioVision to commercialize and further develop its vertical-axis wind turbine (VAWT) based on the proprietary Savonius drag-driven Windstrip? wing system.
  The main requirement for the VAWT is to be able to run at low wind speeds. This was only possible through the use of engineered composite materials to reduce weight and increase strength. The VAWT’s unique design makes it very efficient to capture energy at low wind speeds and generate good output. The blades are manufactured using resin transfer moulding with an epoxy-based system along with an in-mould heating system that can support serial manufacturing. Weight reduction was a challenging design aspect as the turbine can be exposed to sand storms and typhoons. Its low suitable material using TrioVision’s nano-filler technology. The overall reduced blade weight greatly influenced the design by giving the possibility to reduce the unit’s overall structure. Some of the applications for Windstrip’s HPS include automotive, agriculture, cell towers, micro grids, wi-fi mesh networks, residential & commercial buildings, security and surveillance markets.
  Windstrip charging stations for EVs
  The main challenge currently faced in the electric vehicle industry is the infrastructure required to use them widely. Windstrip’s unique hybrid power system is currently addressing these issues to provide 100% renewable charging stations to Lush Motors SUMV. These charging stations can be placed anywher even at remote locations, which promotes the usage of electric vehicles in not just city commuting but also to travel beyond cities. This will totally change the way the automotive segment operates, and eventually all gasoline stations, supermarket parking lots, corporate offices or private residences could convert to charging stations.
  The use of composites is growing rapidly while many segments are trying to change their way of thinking to utilize the key benefits these materials can offer. Using them in both projects (Lush Motors for SUMV and Windstrip for VAWM) tremendously benefitted the end-product.
