Factors that contribute to loss of battery capacity

• Li-Ion battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle. Such aging occurs more rapidly as temperature and discharge loads increase.
• The self-discharge rate of a Li-Ion battery is higher if the battery is left in an unpowered notebook.
• During prolonged storage or non-use, the battery charge will decrease below its recommended low-voltage level.
• Leaving the battery in a depleted condition for an extended period accelerates the decrease in full charge capacity. Leaving the battery at a high level of charge in a high-temperature environment for extended periods (for example, running a notebook computer in a docking station under a heavy load) also accelerates the loss of capacity.
• Running high-end applications using the battery accelerates the loss of capacity. For example, playing 3D games lowers full charge capacity faster than using word processing applications.

Central Bank of Japan on August 30 held an emergency meeting, announced its benchmark interest rate keep 0.1% unchanged, and relief the implementation of monetary policy. Specific measures include: expand the scale of credit and period of low-interest loans. The decision is in line with market expectations. Shirakawa of the Central Bank said, a weakening U.S. economy and the strengthening of the yen is the main reason for the decision.

At the same time, the Japanese government announced in advance a total of 920 billion yen (about 10.8 billion dollars) in new economic stimulus plan. It is reported that funding for recovery from the budget for 2009-10 fiscal year, the government is prepared to fund the program plan submitted to Congress on September 10 for approval and implementation at the end of September.

In order to avoid appreciation of the yen led to the factory moved overseas, resulting in “industrial vacuum”, the government decided to set the subsidy systeme if determine establish LED and li-ion battery production base related to environmental protection, to promote domestic investment companies.

April 2010, the Government of Japan will begin to implement environmentally friendly products points system, buy LED green dots could exchange government grants.

How long will the battery last?

Users often ask how long should their battery last between charges, or why does one model of computer get better battery performance than another. There is no simple answer. Battery life will vary depending on the product configuration, product model, operating system, applications loaded on the product, power management setting of the product, and the product features used by the customer. For all batteries used in an electronic device, the maximum capacity of the battery will decrease with time and usage.

Power plans

A power plan is a collection of hardware and system settings that manages how your computer uses power. Power plans can help you save energy, maximize system performance, or achieve a balance between the two.

Maximizing the capacity and life span of the battery

It is important to be aware of ways that you can care for the battery in your notebook PC. There are conditions that may reduce battery run time and life span.

Bluetooth
All active connections will rapidly decrease your phone’s battery life. Here’s how to turn off Bluetooth:

1. From the Home screen, select Settings
2. Tap Wireless controls
3. Unmark the Bluetooth checkbox.

Other useful tips to maximize battery performance:

1. Only use location services when needed
2. Turn off push email
3. Minimize the use of applications
4. Charge your phone whenever it’s looking low
5. Turn off your phone temporarily if you’re out of coverage or use Flight mode – your phone will consume power when it’s searching for network
6. Turn off Wi-Fi when you’re not using it
7. Close running applications when not in use.

In recent years, JA Solar increasing costs of R & D, develop scientific research, independent research and development of solar cell conversion efficiency rising, costs continue to decrease and the international competitiveness of enterprises growing.

JA independent research and development of new monocrystalline solar cells Secium, the average conversion efficiency of 18.5%, highest 19.2%, the level of leadership in their domestic and foreign counterparts. In addition, the judge also continue to strengthen cooperation in R & D projects, such as the Energy Research Centre of Netherlands (ECN) and other world-class R & D institutions to develop solar cell conversion efficiency of over 20% of the battery.

Polycrystalline silicon solar cells are concerned, the improvement of the justice of poly production technology of solar cells and manufacturing technology, began to bring into production a new generation of polycrystalline silicon solar cells, the average conversion efficiency reached 16.6%, the highest conversion efficiency of over 17%. Production and use of technology efficiency of conversion of 16.2% over revenue, which is a big step forward, the components can increase solar energy production and reduce production costs. JA Solar and established a technology map clear the road, maintain the generation of transfer, research and development production, reserve generation, solar energy technology leadership in manufacturing.

JA developments suggest it will continue to walk in high efficiency solar cell technology and advanced line of commercial production.

The world’s largest foundry TSMC has announced on the last Saturday to initiate the construction of the thin solar cells plant this September.

TSMC Rick Tsai said the new plant focuses on the development of CIGS thin solar modules, this is another big move after bought 20% stake of Taiwan’s largest Solar manufacturing company Motech in January this year. Motech has been the world’s sixth biggest solar cells manufacturers in 2007.

In fact, the plant has begun to build in March this year, and plans to mass production in 2011.

Series of measures taken this year, TSMC positive to enter the field of solar energy, it not only the largest shareholder of Taiwan Motech, and in July it acquired 21% stake of U.S. PV company Stion, got the thin film solar battery manufacturing technology.

In addition, UMC, TSMC rival in the field of thin film solar market in front of TSMC, UMC, since 2005, create their own thin film solar company NexPower, and mass production.

Cai also said that TSMC over the next 12 months, an increase of at least 500 jobs in development of green energy business.

In addition, Taiwan’s largest manufacturers of solar wafers with Sino-American Silicon Products U.S. will also recruit in the next five years 2400-6000 will increase jobs.

Sino American President, Mr. Luo said that the total revenue of the merged company from January to June this year, according to the same period last year, compared with a growth of 80% and 2010 revenue is expected to be more 21 billion Taiwan dollars, the revenue for the company’s forecasts in 2015 will reach 600 to 650 billion.
