全靠电池驱动的汽车 4秒从0到60公里/时[图]
CNET科技资讯网7月20日国际报道 加州一家公司星期三推出了一种电动车,速度相当的快,价格相当的贵。
Tesla 汽车公司已经花费了2500百万美元开发出了一种两人座的敞篷小汽车,其价格在8.5 万到10万美元之间。
这种汽车能够在4 秒钟内将速度从0 提高到每小时60公里,全靠电池做动力。
通用汽车用了10年时间开发出了一种EV-1电动汽车,许多环境保护主义者们希望它可以成为新潮流的先锋,但通用汽车最后却放弃了这种汽车,原因是它的里程数低于100 公里,这使得EV-1无法上市销售。
和EV-1不同,Tesla 公司开发的电动汽车一次充电可以跑250 公里,它使用了锂离子电池,其电量为EV-1电量的3 倍,另外,它的电池重量也只有900 磅左右,EV-1的电池重量超过了1100磅。
EV-1将26块电池连接到一起,Tesla 公司的电动汽车则将6831块电池组合在了一起。这样做的好处是可以将电量集中到一起,另外,如果一块电池坏了,车载电脑将很快查明位置,同时也不会影响其它电池的使用。
这种新型电动车具有一个240 伏电压的充电器,它能够在3 个半小时之内将汽车电量从0 充满,它还可以使用美国家用的110 伏电压,但充电的时间要更长一些。
环保主义者们将Tesla 公司开发的电动汽车称为一个卓越的突破,因为它不使用汽油,全靠清洁的电力作为动力。
目前,美国每加仑的汽油价格为3 美元,用电的成本要更低一些。
Tesla 公司将从星期三开始接受这种电动汽车的预定,明年中期开始上市销售这种新型汽车,公司希望,未来三年,他们能够销售出4 千至5 千辆这种汽车。
Zero to 60 in 4 Seconds, Totally From Revving Batteries

WASHINGTON, July 18 — In a new approach to making the electric car a mass-market product, a California company will unveil on Wednesday a model that is very specialized, very expensive and very, very fast.
Tesla Motors, a four-year-old Silicon Valley start-up, has raised $60 million and spent about $25 million developing a two-seat Roadster that will sell for $85,000 to $100,000.
It goes from zero to 60 miles an hour in four seconds, “wicked fast,” said the company’s chairman, Martin Eberhard. Because it is an electric, the driver does not have to shift into second gear until the car hits 65, he said.
The Roadster comes 10 years after the introduction of another two-seat electric car that was hailed as a breakthrough in technology, the EV-1 made by General Motors. While many environmentalists had hoped that would be the vanguard of a new trend, G.M. withdrew that car as the three-year leases expired, saying that its limited range — less than 100 miles — made it unmarketable.
The recent movie “Who Killed the Electric Car?” argues that G.M. and California conspired to kill a vehicl
