To build a unified standard before the battery lease Network
“Battery price is very expensive, difficult to cycle the financial subsidies, charging areas must rely on the professionals, so ‘change battery‘ approach is more ideal”
Eugene Wong
“For the past, some departments engaged with the proposed hydrogen-based technology course, I think it is the wrong way. Only electric cars is only possible direction for future development of the automobile.” Morning of March 6, Beijing, Deputy Secretary of Supply Industry Association length, power lithium battery system standards Qian Guoliang, deputy director of the Drafting Group on the country for up to 3 hours of the interview, there is no drink of water, to the “First Financial Daily” reporters about his understanding of the automotive industry for the electric, questions and development prospects .
He said that he is hands above their heads in favor of the electric vehicle it has to “replace the battery,” the direction of people who want to have the State take the lead in establishing a nationwide network of charging rent.
“Financial business”: Why do you think electric cars are the future? Rather than the other types of new energy cars?
QIAN Liang-country: There have been many years ago proposed the “three vertical and three horizontal” development ideas.
“Three vertical” is the direction of new energy vehicles Vehicle: pure electric vehicles, hybrid vehicles, hydrogen cars. “Three-horizontal” is the motor and drive systems, battery systems and control systems. This idea is not wrong, but the hydrogen cars in the “hydrogen” is not able to, but the fuel, and now the extraction of hydrogen technology is immature, the cost is higher, not suitable for large-scale development.
The electric car is a great space. When abroad, doing small-capacity power type batteries used in hybrid electric vehicles, our large-capacity lithium-ion battery technology after “a decade sword”, is the world’s leading, pure electric vehicles just need the latter cell .
“Financial Business”: What do you think countries in the idea of electric vehicles like?
QIAN Liang-country: in 2009 introduced the “auto industry adjustment and the revitalization plan,” where is written very clearly, and I very much appreciate.
There are such a plan, “electric vehicle production and sales to take shape. In 2011 to form 500 thousand pure electric, plug-in hybrid and common type of hybrid and other new energy sources Qijuchanneng.” This shows that the future of electric vehicles in several directions .
The document also noted that “new energy passenger car sales accounted for about 5% of total sales.” This sentence how do you understand? This is very clear that the state is hoping to develop cars rather than buses.
“Financial Business”: “replace the battery” or “charging” two kinds of electric vehicles, facilities there are many controversies, why do you advocate “for the battery” mean?
QIAN Liang-Country: I hope the country can come forward to do this sort of thing: engage in a rental network, that is, replace the battery.
Prior to the establishment of this network, first make a standard car battery. It’s like gasoline and diesel sales, the country is 93, 97 gasoline, you want to “98.5″ was simply not find petrol.
The next step is to build a rental network. Network needs to charging device, the battery can be unified, the various equipment manufacturers be able to bid. When the car pulled into this shop, the owner will be able to lease the battery.
Leasing network can solve several problems: The first is battery life. A taxi daily mileage of 300 to 400 kilometers and is 140 thousand kilometers a year. State regulations battery life to more than 15 thousand kilometers.
An ordinary car battery price is 6 million yuan, 600,000 yuan is a bus. Countries, while subsidies to the pure electric passenger cars 500,000 to 60 million, a pure electric vehicles to S.6 per million, but subsidies can it last? When the batteries run out, or the incumbent, the battery does not do? The price is still high, that is, “financial” subsidies are limited, is not easy to cyclical payment.
The rental station to solve this problem. Because when you buy a car, not including batteries. You can rent from the rental network to another to pay for electricity.
There is also a lithium battery overcharge or over-discharge problems. Charge was too far, and will be blasting; discharge too much can also cause short-circuit. These checkpoints should have a professional to grasp, the residents themselves at home, if sufficient, can master this? And leasing the network of professionals can solve these problems.
The use of charge mode, then the inevitable use of “quick-charge”, the “slow charge.” “Quick-charge” would have a significant impact on battery life. “10 minutes could be the battery is full 80 percent” was now impossible to do so. The power left 30%, 40%, the charging time of 2.5 ~ 3.5 hours, so “replace the battery” approach better.
