The New York Times has a detailed breakdown of the final stimulus bill as it relates to energy here. The Wall Street Journal also has a useful graphic that puts that spending into context. The Congressional Budget Office details the costs of the bill over several years here (PDF). And, in a story posted today, I break down how the bill could help kick-start an advanced 434674-001 industry in the United States.

In previous blogs, I've mentioned two key provisions for renewable energy that were up for debate because of ex942aadifferences between the House and Senate versions of the bill. Both made it through.

The first allows businesses that invest in building renewable-energy facilities (such as wind and solar farms) to claim a government grant that covers 30 percent of the investment, rather than claiming a tax credit. The change is important,hp pavilion dv9000 battery, as many companies can't claim the credit because they have no tax liability. (The tax credits plus grants are expected to cost the government $14 billion.)

The second is a credit for building manufacturing facilities for renewable energy as well as advanced batteries, which could, for example,hp pavilion dv9100 battery,hp pavilion dv9200 battery , hp pavilion dv9500 battery , hp pavilion dv9600 battery encourage solar-panel manufactures to build plants in the United States.

Nokia Corp. is offering to replace 46 million batteries made by another company for use in its mobile phones because of a risk of overheating, Nokia said on Tuesday.

The faulty batteries were manufactured by Japan's Matsushita Battery Industrial Co. Ltd. and sold in a wide range of Nokia phones, from its low-end 1100 family of products to its pricier N91 and E60 devices.

The overheating can cause the sony laptop battery to "pop out" of the phone while it's being recharged, said Nokia spokeswoman Marianne Holmlund. She said there was no risk of fire, although it was unclear what caused the minor incidents reported.

"It may be that the device left a small burn on a shelf while it was recharging, it's hard to say for sure," said John Devlin, research director for mobile technologies with IMS Research in the U.K.

People concerned about the problem can get their battery replaced for free, Nokia said. It set up a Web page that lists the phone models and describes how customers can check if their battery is affected.

The problem exists only with Matsushita sony vgp-bps5 manufactured between December 2005 and November 2006, and the phones would have been sold worldwide during roughly the same period, Holmlund said.

Nokia reported selling 347 million phones in 2006, making 46 million a significant proportion of its annual sales. "It is about 10 percent of all the phones sold, but we are talking about 100 incidents, which is only a tiny proportion," Holmlund said.

Nokia expects Matsushita to bear "certain financial responsibilities" for the replacement program, she said. Peter Weber, a spokesman for Matsushita in Europe, said the financial terms are being negotiated now between the companies.

It's the first time Nokia has had to offer such a replacement program, Holmlund said.

Such problems in phones normally arise because of counterfeit batteries, making this case "a little unusual," Devlin said.

The problem is unlikely to affect other makes of cell phone since the batteries were designed especially for Nokia, Weber of Matsishita said. Cell phone batteries are typically designed and manufactured for a particular phone maker, Holmlund confirmed.

It's only the latest incident involving rechargeable Lithium ion batteries used in portable electronics products. Late last year laptop makers including Sony Corp., Toshiba Corp. and Dell Inc. offered to replace a total of 8 million laptop batteries because of a manufacturing defect in Sony-made batteries that left them vulnerable to short-circuiting and catching fire.

Nokia said it will work with Matsushita and the "relevant authorities" to investigate the problem.

Thin, large-capacity, long service life, these are the outstanding characteristics of lithium hp f2024b . For this reason, lithium-ion battery was quickly replaced by nickel-metal hydride and nickel cadmium batteries role as notebook computers, portable products, the preferred range of equipment. Near Period, discovered in a row of notebook hp 337607-001 explosion, the notebook battery time and again to the air waves, lingering fear that end users, lithium batteries in the end is the source of power or time bomb?

The study found the omnibook xe3 battery on fire mystery

In general, the current notebook lithium hp 346970-001 pack itself with better protection.


It not only by the series / parallel multiple hp hstnn-db02, also contains its own circuit substrates two modules: the protection of Circuit substrate (Protection PCB) module and the Smart Battery Gauge Board module, a set of batteries to protect its design, including the first-class Protection of the IC (to prevent the battery charge-off, let-off, short-circuit), the second-level protection IC (for the second time to prevent over-voltage), fuses, LED direction, temperature regulation, and other components.

In the multi-level protection, even in the power charger, notebook unusual, notebook pavilion dv1000 battery can only be changed automatically to protect the state if the situation is not serious, often re-plug in after normal work can not Will be an explosion. Notebook battery exploded in the face of serious facts, ask the reporter of Xinhua professionals as well as a well-known manufacturers of design engineers.

According to the analysis of lithium pf723a,pavilion zt3000 battery from Wu Waihu explosion or short circuit had caused sufficient, the biggest is the possibility of a lithium battery at the time of manufacture, because the manufacturing process itself flawed, because the product can occur at any time there is a potential safety problems, such as should be The insulation between the metal poles of dust or copper foil and aluminum foil pierced the glitch is a lack of short circuits caused by micro. The former is the most serious, as a direct result of a large number of short-circuit and heat production, resulting in vaporization of some of the electrolyte, the battery case Stretch.

In addition, there is a rather exceptional power charger or laptop computers due to special reasons, lithium pavilion dv2000 battery to provide instant high-voltage / current strong lead over the serious charge, such as the charging voltage 12.6V by the sudden rise to 12.9V Or more, this time there will be a charge of high-flow generation, in-house circuit the battery charge current should be cut off action, but some of the lithium battery over-voltage, over-current protection design is very weak, which may result in damage to the battery protection IC, So that the notebook battery to make the protection and the damage after a charge-off around the needle-chip lithium metal crystallization of the piercing point resulted in a number of micro-short-circuit, causing the battery temperature gradually increased until the final battery explosion, the fire occurred, This is a lot of notebook hp hstnn-lb31 "hot" the main reason.

Add a layer of protective cover

At present, the mechanisms for the protection of the hp f4486b , pavilion dv9000 battery from the point of view, rechargeable battery pack in front of some of the traditional chip makers are mostly provided by the program play a precise control of charge voltage and charge current role in the over-voltage and over-current control does not provide corresponding Solutions. In this way, for the protection of the battery pack is entirely dependent on the battery itself, such as the charge-off protection, over-discharge protection, charge-off protection, have put current protection, over-temperature protection and so on.

Protection in place as a result of the need to prevent first-class IC protection MOSFET failure or short-circuit caused by over-voltage fault, so the second-level protection IC will generally be considered is the protection of the battery pack in the last line of defense. In this connection, e-convex (O2 Micro) Hong Shi Zhen product manager, said the different views, in his view, for the protection of the battery pack can be moved forward through additional controls on the charger to realize the detection and control of hp cgr-b1870ae charging action, which will no doubt further enhance the level of protection, The use of lithium hp 337607-003 on the protection of security.

To this end, O2 Micro in power management for portable devices developed by Cool Charge solutions, the integration of a project called Cool Battery Technology battery protection technology, which is the main feature of a traditional general Chargers do not have OVP (over Voltage Protection) and OCP (Over Current Protection) function to protect the two pavilion zd7000 battery , pp2182d battery , the technology has been Cool Charge IC chip embedded in them.

Cool Charge IC chip used, the power charger to a large extent, take on the responsibility to protect the hp 338794-001. Cool Charge IC subject to the control of the charger in comparison with the traditional design (see Figure 1), needed to significantly reduce the external device And eliminate the need for Q3 and Q4 part of the design, reducing the failure rate. Preserved in the Q1 and Q2 (to improve the original design of components) between, Cool Charge IC set up a detection point, the factory settings, the Detection of point voltage and current settings are slightly smaller than the battery manufacturers to set safety requirements. In this way, in charge voltage or current beyond the Cool Charge IC set up security after the voltage or current value, IC control Q2 off, the first battery Protective effect before the cut off charge; from the frequency of detection, protection, detection of hp pavilion dv8000 battery time for the millisecond level, and through the chip to detect, you can easily achieve the level of seconds per million, can be very high The frequency of detection in a row, thus realizing the first step in the protection of the battery pack.
