Advantages and Disadvantages of EVs
The most obvious advantage of electric car batteries is that they don't proce the pollution associated with internal combustion engines. However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels. Of course, this proces pollution. But how does the pollution proced by burning fossil fuels to recharge electric car batteries compare to the pollution proced by internal combustion engines? According to the Electric Vehicle Association of Canada, or EVAC, even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plants, can rece carbon emissions to less than one percent of those currently proced by internal combustion engines. So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars.
Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. The United States Department of Energy has calculated that a typical EV can run for 43 miles on a dollar's worth of electricity. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.
Yet another advantage of these rechargeable batteries is that they recycle well. Almost 100 percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.
The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time. At present, this means a drained EV will be out of service for several hours before it's fully recharged. Of course, this is a serious disadvantage. In the future, faster recharging technology may become available, but in the near term, electric cars won't be the vehicles of choice for long trips. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one. This system would allow batteries to be recharged outside of vehicles and would greatly rece the amount of time required to get an EV up and running again after its battery is fully discharged.
Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power. These collections of batteries are heavy. The lithium-ion battery pack in a Tesla Roadster weighs about 1,000 pounds (453.6 kg). That's a lot of weight to carry and it can greatly rece the car's range. However, the designers of the Roadster have offset this battery weight with a light frame and body panels. The entire car only weighs 2,690 pounds (1220.2 kg) -- not terribly heavy when you consider that more than a third of that weight is battery.
Given the importance of the battery to an electric car, you might wonder what will happen as that battery grows older. How long will it be able to power the car? And when it finally dies, can it be replaced or is it simply more economical to buy a new car? Read on to find out.

The lighter drive 更輕便的駕駛理念
Electric cars made from carbon fibre will be safer and go farther
電瓶汽車+碳纖維材料=安全，耐用

They look safe in thereMARK WEBBER has a lot to thank tiny strands of carbon for. When his Formula 1 car cartwheeled in a spectacular 306kph (190mph) crash at the recent Valencia Grand Prix, what helped him to escape unscathed was the immensely strong carbon-fibre 「tub」 that racing drivers now sit in. Carbon fibre is an expensive alternative to making things in steel or aluminium, but besides being extremely strong it is also very light. It is found in high-performance parts, like aircraft wings, bits of supercars and the frames of pricey mountain bikes. But if work by Germany』s BMW proves successful, it could also become the material of choice to mass-proce electric cars.
6月，F1瓦倫西亞大獎賽發生了驚人一幕：以每小時306公里（190英里）行駛在賽道上的馬克�6�1韋伯發生了嚴重的翻車事故。奇跡的是，韋伯本人毫發無 傷。奧妙之處就在於當下流行於F1的——碳纖維底座。雖然與鐵，鋁相比，它的造價較高，但是抗壓及輕便性都遠遠好於鐵和鋁。目前，炭纖維材料還大多使用在 高精度領域，如飛機機翼，F1賽車，或是私人山地車等。不過這一傳統觀念可能會被寶馬公司打破，一旦試驗成功，那麼碳纖維就可以率先廣泛應用在電動汽車領 域。
The Bavarian carmaker plans to launch a new plug-in electric car in 2013. It will be one of the first designed from scratch to use an electric motor rather than being converted from an existing model. Recing the weight of this four-seater car, known as the Megacity concept, will be crucial to improving its performance and range. So BMW is planning to use no steel at all. The Megacity will be built as two moles: an aluminium chassis will contain the electric drive-system and battery, and a body made almost entirely of carbon fibre will be fitted onto it.
德國汽車製造商正計劃將在2013年推出一款電瓶可拆卸式環保車。這並不是從現有車型改裝而來，而是設計師卧薪嘗膽的一次全新嘗試。更輕便的4人坐駕，完 全符合現代城市環保理念，這款「無鐵」車型的設計，彰顯出了它的與眾不同與理念上的更新換代。但是這樣一個設想目前還處在起步階段，或許成功的那天，汽車 鋁制底盤上充電駕駛裝置與設備，及全身碳纖維的設計工藝，能夠更好的詮釋大城市的環保概念。
Carbon fibre is 30% lighter than aluminium and 50% lighter than steel. The fibres are extremely tear-resistant. When woven into a lattice structure and impregnated with resin they can proce a part that is stronger than steel. The trouble is the process is labour-intensive and slow, not least because components may have to be cured for hours under pressure in massive ovens called autoclaves. For carmakers, used to stamping out steel body-parts in a few seconds, this has ruled out carbon fibre for high-volume proction. BMW, however, aims to change that.
碳纖維比鋁輕便30%，是鐵的50%。同時，由於纖維具有極強的抗斷裂性，再融入樹脂形成晶體結構後，那麼它的強度就要超過鐵。但是這道工序屬於勞動密集 型，效率相對較低，以前車用鐵製品的切割僅需要幾秒鍾時間就能完成，而現在則需要在高壓爐內高溫鍛造幾個小時，因此，大量生產碳纖維的可能性不高。不過， 寶馬公司目前也正在試圖改變這一情況。
Its proction line starts with a so-called precursor: a fibre spun from a polymer. This is carbonised by heating it in multiple stages to leave indivial carbon fibres just seven microns (0.007 millimetres) thick. Around 50,000 of these fibres are bundled together into a yarn which is then made into a fabric. This can be cut and handled like a textile. Strips of fabric are then overlaid to align their fibres in such a way to maximise their load-bearing characteristics as required—in effect tailoring components like a bespoke suit.
現在，寶馬生產線守開先河，將聚合體加工成纖維狀，這個碳化過程需要在高溫下進行幾道工序，最後產生的碳纖維厚度只有7微米（0.007毫米）。然後，大 概將5000根這樣的纖維擰成一股就成了纖維織物，再將這樣的纖維根據它的陌生能力將它切割成最合適的尺寸，實際上，這個步驟與量體裁衣有異曲同工之妙。

Along come the robots 自動機將助一臂之力
BMW uses molds, heat and pressure to proce contours in the fabric. Resin is then injected into the molds to bond the fibres together. How the resin flows through the fibres is crucial; it has to be done quickly and leave no area untreated before it starts to cure. A release agent in the resin migrates to the surface to prevent the component sticking in the mold. The whole process, which can be handled by robots, is completed in minutes.
然後，再利用模具與高溫將纖維織物打造成型。首先，將樹脂注入模具粘合纖維，這里有兩個細節非常關鍵，一是動作要快不能拖泥帶水，二是在沒有粘合之前確保 模具內的樹脂流向均勻。樹脂中混有的隔離劑此時發揮功效，避免了纖維與模具發生粘連。整道工序，在自動儀器的協助下，僅需幾分鍾便可完成。
The resulting carbon-fibre parts are bonded together to construct the body of the car. Besides their lightness, BMW』s experimental vehicles have exceeded expectations in crash tests, says the company. During front- and rear-impact-tests the aluminium chassis crumples to absorb energy, but leaves the rigid carbon-fibre passenger compartment intact. Even extreme side-impacts protected the crash mmies and the battery (automatically switched off when the airbags trigger). In many cases crash damage is reparable by cutting out broken sections of carbon fibre and bonding in new ones.
此時的碳纖維就可以應用於汽車製造。寶馬公司聲稱：除了超輕便的特性之外，碳纖維的抗擠壓能力也令人驚嘆。在對車頭車尾抗沖擊測試中發現，一方面是鋁制底 盤受到擠壓而變形，緩沖了部分能量，而堅硬的碳纖維能夠保證車身安然無恙。即使是側面來的強力沖擊，也能夠有效保護車廂內假人模型及電瓶毫發無傷（當然， 氣囊裝置啟動電瓶能夠自動斷電）。即便是車身有所受損，也不用擔心，切割掉受損部分再粘合上新部件，完全可以讓車體恢復原狀。
At some point, however, carbon-fibre cars will be scrapped. Steel and aluminium is easy to recycle, but carbon fibre is tricky. Carmakers are working with aerospace firms on ways to do it. BMW has pioneered a process to reuse offcuts by breaking them up with heat to turn them back into raw material. This can be used to make composites with about half the strength of new carbon fibre.
鋁的回收再利用技術已經非常成熟，但是從某角度來說，碳纖維這方面的技術還有待研究。目前，製造商正和宇宙空間機構合作，試圖填補這一空白。眼下，處理碳 纖維「邊腳料」最先進的方法還是來自寶馬公司，他們通過高溫分解，能夠使之退回成未加工狀態。通過此種方法生產出的復合材料也具有碳纖維一半的硬度。
Another advantage of a carbon-fibre body is that it will not corrode. So, apart from the battery wearing out in ten years or so, electric cars could last for decades (electric motors need little servicing). This will make it even harder for car designers to persuade those driving electrically to trade in their rustless, tough-as-old-boots vehicles for a new model.
碳纖維的另一優勢在於不易腐蝕，如果不考慮電瓶10年左右的使用壽命，這種碳纖維電瓶汽車可以使用長達幾十年（當然馬達還是需要檢修的）。與結實耐穿的靴 子讓人不忍丟棄一樣，當設計理念再有突飛猛進的發展時，如何讓使用者放棄碳纖維電瓶汽車，設計者可要好好動一番腦筋嘍。
