塔城翻译公司关键字：Because high-performance car is designed to open more distance, there must be relatively large range, relatively large speed speed big, the weight of the car should be increased accordingly. As a result, the electrical power requirements are more large demands on the battery capacity will be relatively large problem is a large batteries cost a lot of big, bad economy. For example, if a car with major 330 kg (plus two people, the whole weight of about 440 kg), range 80 km, 55 km speed performance of four ultra-miniature, low electric vehicles compared to 1,000 kg (plus three people, all hit 1160 kg) weight of the electric Xiali 2000 is 3 times the range is 3 times the average rate has increased doubled, so that the battery capacity will increase to seven times, while the battery charges are basically the same battery capacity is directly proportional, so high-performance battery charge equivalent to cart low-performance electric vehicle seven times that of electric Charade 2000 a year of battery charge is a million words, 330 kg of super-miniature, low-performance electric vehicle battery charge for one year only 1,500 yuan. As a micro electric car economy came out. Also, if the electric car To open the distant road, no public charging stations can not. charging time too long, and short-haul trucks do not have this problem as long as the charge on it at home, so as the battery charges and public charging stations, and long charging time The problem, in fact, a pure electric car is not suitable to open more distance, it is only suitable for shorter range, slower, lighter vehicle weight analysis of the characteristics of electric vehicles and economy, consider the situation to the United States can be sure that pure electric cars in the U.S. is not a great market毕业论文翻译成英语文章, mainly because the Americans to work翻译毕业论文公司哪里有最权威 distance, usually one or two hours of driving time is to go shopping, I often go to the supermarket毕业论文翻译成英语文章 to tens of kilometers away because Americans drive longer distances, and faster. pure electric cars can not meet their论文摘要翻译英文 requirementscompletely英语论文翻译公司 different situation in China and most Chinese people to work翻译毕业论文公司哪里有最权威 away from the city no more than 20 km, in Chinese cities, the speed and rarely up to 60 km so that a weight of about 330 kg (half the size of Otto), containing two people, a range of 70 to 80 km Maximum speed of 55 km of ultra-miniature city on the
