Electric cabs charge less battery life and require battery technology

　　In many city streets, there is a taxi. There is no noise, no exhaust, and it‘s called a pure electric taxi. According to the relevant documents, new taxis in Beijing will be replaced with electric cars. However, the reporter interviewed some electric taxi drivers, but found that many drivers didn‘t want to leave. What is the reason for this?

　　

　　Mr. Zhang‘s taxi company has more than 500 electric cars, and Mr. Zhang says it is difficult to charge a car every day.

　　

　　Electric taxi driver Teacher: so now is charging pile, the layout of many places might be odd change, in some places just one or two. That means you have to look for it in general, and you don‘t mean to say that you want to see it.

　　

　　For where to recharge, drivers are generally search from the mobile phone software, they all have a can only be used on company charging pile electric card, and then do a piece of state grid card, but often encounter CARDS are not compatible.

　　

　　Electric taxi driver: I did three. This is guodian, the guodian charging pile of the card, company and society, I have to call, that didn‘t brush card that direct phone code, online payment.

　　

　　Each of the charging stations, each of which is incompatible with the electric card, creates a problem for drivers. According to the reporter, the electric car is slow to charge 7 hours, quick filling a second half hour. Drivers typically spend the night at home, pulling up during the day, and charging them up quickly when they‘re running out of electricity.

　　

　　Electric taxi driver: the eight-hour day is basically five hours of work, and it takes about three hours to recharge. I‘ve been running for two hours today, and you can‘t go to the airport. You can only explain to the passengers that I am a tram, and that the range is not enough.

　　

　　The range short charging facility is less competitive

　　

　　Although the electric vehicle charging fee is much cheaper than for fuel, but the range is short, fast charging facilities, the charging time less cost higher a variety of reasons, lower its competitiveness as a taxi.

　　

　　China road transport association Wang Limei: so the new energy car obviously its technical and economic characteristics and block it completely different, it doesn‘t burn oil, its electricity, electricity in where? What time does it charge? So for the moment, obviously, the system is not as perfect as the gas station system that used to be.

　　

　　Electric cars will lose a lot of mileage in winter

　　

　　A range is a measure of how many kilometers a car can run after it is full of electricity. Many electric taxi driver, said mark out of range will exist in the actual driving a variety of discount, for example, this situation is particularly evident when low winter temperatures.

　　

　　Electric taxi driver: for example, in the winter, the car falls off a lot of electricity, and you can see that it‘s 200km in nominal terms, and you can‘t run for 100 kilometers.

　　

　　Expert introduction, if the environment temperature is below zero, the battery power is more than two hundred and thirty percent attenuation, range is short, and generally use the warm wind in winter, it‘s more cost electricity.

　　

　　Electric taxi driver: (now) more than two years later the virtual electricity, you look at me with a range of 61 km, the last time I eat a meal half an hour, also wait come back and then there were 28, came so close to the charging stations. I left my half way back when I was driving.

　　

　　According to reporters, the range of electric taxis in Beijing is currently around 220 kilometers, and drivers say they need to be charged every day outside.

　　

　　China road transport association Wang Limei: in general, 500 km is a relatively good energy cycle, taxi and its 100, 200 kilometers, so his two days or three days added oil at a time, in this case, the production and business operation activities of his whole interference is not very big.

　　

　　Improved mileage requires battery technology

　　

　　According to the reporter, at present domestic electric electric electric car range is commonly in 200 to 300 kilometers, some foreign model can do 500 kilometers, but the price is very high. So for domestic electric cabs, can you do 500 miles?

　　

　　Beijing institute of technology, deputy director of national engineering laboratory of electric vehicle Lin Cheng: of course you can do it, you want to run 1000 can, you can run as long as the car is full of battery, which is inside the industry is always a debate, is considered to be the short electric car mileage, is how to solve, actually not too much, the best way, is more batteries, but more battery brings a series of problems, this car is very, very heavy, have a very low efficiency, the cost would be very, very high, the quality it will be more than two tons, so we have the car fuel only 1.2 tons, 1.3 tons, right? So this is a technical problem, and that‘s progress in battery technology.

　　

　　Experts say, if you want to increase the range must wait for the development of battery technology, according to introducing, the 2008 Olympic Games with the battery would be about 100 watt-hours per kilogram, now can be done from 150 to 150 watts.

　　

　　Beijing institute of technology, deputy director of national engineering laboratory of electric vehicle Lin Cheng: in other words, they said the car was originally can run 100 kilometers, so now you can generally run 100560 kilometers, this is progress. And our country is planning another two or three years, three or four years later, the power could reach more than 200 to 250, then the of ascension is increasing rapidly, and the weight is constant, so we have to patiently wait for the material technological progress.

　　

　　The suburban pilot model is good

　　

　　Journalists know that in some cities taxis are replaced by batteries. This will save drivers nearly two or three hours of charging time each day. So is it possible to break the short range of taxi drivers?

　　

　　In an electric car exchange scene in daxing district, Beijing, reporters saw a taxi switch from electricity to finish in just four or five minutes.

　　

　　Zhang baoting, the head of an electric car taxi company in Beijing, has supported the 24-hour operation of the electric car. Increased its operating radius and operating mileage.

　　

　　Beijing‘s current electric taxi is still only a pilot in some suburban taxi companies, but it works well.

　　

　　Electric taxi driver: the trolley is quite good, it itself is small, the change about electricity than the convenient and fast, the charge before charging must charge for an hour, after all, have to wait.

　　

　　It is understood that in the change of electric facilities construction, Beijing has started 50 in power plant operations, will expand to 200 by the end of in power station, the city and the realization of key transport hub area of 7 km radius "in electricity", alleviate the taxi driver range anxiety and charging difficult problem.

　　

　　Beijing electric taxi, head of the company Zhang Baoqi: a traditional fuel vehicles taxi driver, every month he consumption of oil, so he had to spending money, probably should be in 3500 yuan or so, so pure electric vehicles? He paid charge money every month, that is, in a little more than 1000 yuan, 1500 yuan between, say, in the electric plug-in electric cars, his spending electricity as fuel cars pay fuel, probably was reduced by two-thirds.

　　

　　China road transport association Wang Limei: for the city the environmental pressure is too big, so I‘m afraid of new energy vehicles clean production is an inevitable process of a progressive, including taxi service that kind of the choice of the means of production, I‘m afraid all is to gradually in new energy this direction, reduce the pressure of environment.
