A fuel bus, about 35 liters of fuel per hundred kilometers, if you press 0 # diesel 4.78 yuan per liter basis, energy consumption per hundred kilometers cost 167.3 yuan. And an electric bus, hundred kilometers consumption 60 kWh, electricity price is 0.5 yuan per kilowatt hour, then the energy cost of 30 per hundred kilometers than the fuel savings of 137.3 yuan bus.

Today, more and more electric vehicles in the domestic market. As the core of the energy components of electric vehicles, lithium ion battery is about to become a key factor in the development of electric vehicles.

The end of 2007, in the lithium-ion battery industry ushered in unprecedented opportunities for development, the sky Energy (Luoyang) Limited shall be fixed from time to time, invest 100 million yuan, annual output of 30 million lithium-ion battery safety projects. Project was put into operation in April 2008, when it realized sales income of 80.23 million yuan.

“Now the power battery domestic production enterprises have three to five, and they are monomer production capacity of 100 Ah lithium-ion battery below. Our company is currently achieving 40 to 400 Ah single cell production capacity and product through the national mandatory safety inspection. “Sky Energy (Luoyang) Limited responsible person, with continued research and innovation capacity and the level of advanced battery projects, the sky has become a large-capacity energy lithium-ion battery leader, and in international advanced level.

Because the battery price is high, the purchase price of electric vehicles is relatively more expensive fuel vehicles, but the life-cycle cost comparison, the electric car but has a strong advantage. With the technology industry matures, accelerating industrial upgrading, the cost of lithium-ion battery is bound to greatly reduce that time, more and more electric cars will demonstrate its strong vitality.

This year in June to the end of 2010, 1.7 billion investment in the sky energy II project will build an annual output of 700 million Li-ion battery production capacity when security; the beginning of 2011 to 2013, the sky will invest 1.8 billion energy start Phase III project, a total annual output of 2.0 billion lithium-ion battery production capacity Ah, to 2013 sales revenue 11 billion yuan, sales income in 2015 15.0 billion.

Leading, with a new green world influence power supply industrial base are in the pipeline, it lithium-ion battery as the core, supplemented by electric vehicle powertrain, power management, charge management, energy storage system and other industries, will drive the region rapid economic development.

Economic and Technological Development Zone, Jiujiang City, was informed that the International Group of Hong Kong Sheng joint investment of 3.0 billion yuan in the construction of photovoltaic solar cell project in Jiujiang contracts signed before the project is expected full production, the annual output value of more than 10 billion yuan.
   
It is reported that the project mainly produces solar cells, solar cell modules and their supporting systems integration products. This article from Network World PV

Project in three phases, in August 2011 to complete the project 100MW solar cell and module production, in April 2012 increased to complete the project 200MW solar cell and module production, in December 2012 before the full completion of 500MW solar cell and group pieces of the project into production.

Laptop, you use it? Laptop batteries that you use and how much they mastered? Long-term use to connect the power of the books, how should we save a good laptop battery it? Problems seem less important, in fact, affect the laptop battery life, want books with a bit longer? Then let us learn about battery use it!

Most laptops are equipped with automatic down-conversion function, so that the benefits of the books is the maximum extension of battery life. Many people who use the Celeron may have questions about the books, our books do not have this feature, is not naturally less power out? CPU power consumption is only a part of, in fact, the order should be like electricity: LCD> CPU (full speed)> Graphics> Wireless LAN> CPU fan. In other words, in addition to CPU, we have still other aspects, reducing the maximum power consumption.

The control panel in WindowsXP has a power management option, the “power scheme”, set the LCD screen in idle for about 10 minutes off the most reasonable, and the hard disk will have to set more appropriate in 15 minutes. The moment of launch will take some hard power is not that frequently start and stop on the hard disk damage is considerable. Of course, you can also manually turn off the screen, most of the books through fn + F3 function key to achieve.

Set LCD, hard drive shut down time, and if necessary to further save power, but also the operational status of the system to adjust, it is not able to do the WindowsXP. The Thinkpad, for example, most of the books have built-in battery management software, general books will provide eight-screen brightness adjustment, although the bright state can get the best visual effect, but it is very, very power-hungry, so , edit the document or some other common application to adjust the screen brightness to the lower six or seven most appropriate. At the same time, CPU can also set the best battery performance, CPU fan running status set to “balanced” more reasonable.

Some low-priced books there is no battery management software (because there is no built-in power management chip), but you can use the generic battery monitoring software to manage the battery. BatteryMon is a good paragraph.

Many people use the laptop battery, see the power started to charge less than 100%, but this will accelerate the reduction of the total electricity capacity lithium, long down, the battery life much shorter time, but also greatly shortened life expectancy . Therefore, the recommended limit is lower than 10% of the charge re-charging, but also careful not to set too low, such as the use to only about 3% charge left, it is not enough science. Low power alarm must be set, generally less than 10% of the alarm as well, less than 3% of the serious alarm means that the battery is insufficient to support the next boot into the system. Many battery management software is the default start charging less than 96%, this will damage the battery charge, so be sure to change this setting. In addition, the best off charging the battery so that conservation can play a role.

If the laptop battery power for a long time greatly reduced, the depth of discharge can try to “save” it. This is a “dead horse a living horse medicine” approach, not a last resort, it is best not to do so. The simplest method is to discharge has been running the program, less than 3% of electricity to restart the laptop into the BIOS after the vacancy to run until the automatic power up. Then the depth of charge, charging time to reach eight hours, but not more than twelve hours, which would allow lithium to restore some power.
