My battery world

For the lithium battery “activate” problem, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery.

This “The first three charging more than 12 hours to charge” was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication.

Lithium batteries and nickel battery charge and discharge characteristics are very different, the access to all the serious official had technical information are stressed and over-discharge rechargeable lithium batteries will, in particular liquid lithium-ion battery causing great harm.

Charging the best time and the standard methods according to the standard charge, in particular not to carry out more than 12 hours of super-long charge, usually, cell phone charging instructions presented method is suitable for the mobile phone standard method of charging.

In addition, lithium batteries cell phone or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white charger is also sufficient.

To place a long time unused, or that the charge that is frequently used for some time, the methodology is a complete charge and discharge, after which the battery charge on which you can use that only long-term use is only necessary for complete charge and discharge once again re-calibration.

Fuel cell is divided into fuel cells, phosphoric acid, alkaline fuel cells, in proton exchange membrane (PEM) fuel cells, solid oxide fuel cell, the fuel cell and molten carbonate fuel cells reversibly different types, different characteristics, does not use exactly the same thing. Proton cell membrane exchange fuel represents the latest advances in fuel cell, its thermal efficiency higher than 45% ~ 65% efficiency of internal combustion engine that typically 20% to 30% if the battery of a great potential in automotive applications.

        Fuel cells a wide range of applications, can be used in mobile phones or appliances, but can also be used in transport. Including Japan, the United States, the European Union and other countries in developing pollution-free cars to fuel cell.

Suppose in 2009, China produced only 5 million electric bikes, but as long as 1% of the new electric bike using a fuel cell, then it will become the world’s great potential in the emerging market for fuel cells.

Hybrid is the development trend of new energy vehicles

Operating in different countries, class car of new energy technologies vary widely. Brazil to develop new automotive technologies, renewable energies. If the United States, Europe, Japan and other traditional consumers of the country’s main vehicle to develop a technology pure electric vehicle, the technology of hybrid electric vehicle technologies and fuel cell vehicle, three types of electric vehicle technology. As the existence of natural resources, bio-technology, energy constraints, the current car technologies include new energy, primarily in the technology of electric vehicles based.

Technology electric vehicle motors can be divided into a pure electric vehicle (EV), hybrid electric vehicle (HEV) technology and fuel cell vehicle (FCEV) three technical schools. A technology for commercial production of pure electric vehicles and hybrid electric vehicles.

Pure electric vehicles and vehicles with fuel cell in the car using the process to achieve zero emissions, and completely free from dependence on oil resources, development of new energy vehicles will be the ultimate goal, and selection road during the transition due to cars alternative energy and health energy vehicles more dependent on physical energy associated with the development of regional characteristics, it is difficult in the global promotion, improvements in hybrid electric vehicle technology for existing vehicles is relatively small, in the period of high oil prices has improved fuel economy of sex, and to meet higher emission standards, the transition is the best way.

The current hybrid cars use nickel-hydride technology battery major metals, while the energy density of lithium batteries with large capacity, no memory, etc., are car manufacturers and battery suppliers unanimous approval of the need solve the problem today lies in its use of the stability, security and cost of production.

The battery, I believe that many consumers is the first Lenovo BOMB, many battery manufacturers time to remember the major events, so we are still recovering. We have also seen many reports on the explosion of the battery, leading to the cause of the explosion of the battery varies, but these issues never seem Gaibu Diao, each manufacturer has released it’s not our fault we must rely on the plant Lai good batteries, and battery plant is to remain silent. Now is the standard lithium batteries, and now the media flying in fuel cells and other cells of news everywhere, is not with the life of the double upgrade raised the risk also doubled. Especially given the fuel cell was actually a time bomb, hoping the technology has also advanced to the bomb was placed inside the bomb can not tack.

Drum parts, manufacturers may make small, and nothing but the application is based on the design of notebooks designed with different shapes, the basic performance depends entirely on batteries. The so-called intelligent charge control and discharge, it is able to rapidly achieve effective charge. This Hewlett-Packard, Dell has a model to support .

1 No. 1 cell buried in the earth, and make a square meter of land permanent loss of use value, the piles of waste harmful to the environment is great. Formosa university professors and graduate students Bing Yang Liao Chung-Pin Huang, Chen Junlang environmental research and material development of the biological cell is taken from nature, like the leaves of the banyan tree, and even the weeds on the roadside by the extraction of chlorophyll is made of organic electrolytes, made a 3, the size of the battery voltage can be up to 1.5 V, currents up to 150mA or more, you can listen to a permanent two days, mp3, 4 batteries can be switched to LED lights to keep more than 9 days. The invention of the 2008 Taipei International Invention Gold Medal competition, also apply to patents outside the island.

Liao Chung-Pin said that many students had been experimenting in Apple’s power generation is to use organic principles to produce electricity, but the currents are too weak. He developed a series of pure organic chlorophyll is currently the largest in the world today organic batteries, power is Japan’s “Cell” water twice. And no electricity is used when cleaning the bathroom for 10 seconds, you can answer the new power use. More than cleaning the bathroom can be loaded, and even tea, cola, coffee, juice and other aqueous solution as long as they can, and nature to survive an emergency, n ‘ there is no water, electricity can also be uric health.

Liao Chung-Pin said that most batteries contain highly toxic chemicals can easily damage the environment, we must make appropriate recycling and has developed a battery within the filler material is organic, biodegradable polymers of chlorophyll even if it is to throw, he would not harm the environment.

Director of the Center incubation Huwei HKUST, said Xie Longchamp, the degrees environmental cells that organic solar cells, but also because protecting the environment, raw materials cost, size and shape of changes elasticity, but also unique in the world of new invention mai one day change the world’s future energy development, would replace more than 30% of the planet dry.

The Government of Kenya announced that it would halt imports of the world’s 37 brands of dry batteries, in order to rectify the domestic battery market.
     

       Kenya “Business Daily” 3 reported that the fake batteries flooded the local market and cause great economic loss to Kenya. Poor quality of these batteries, power a short time in the use of heat and could be easily exploded.

       Kenya’s quality inspection departments of the country’s market post-test battery to identify 37 kinds of brands of batteries do not meet safety standards, decided to ban their entry into the market in Kenya.

       Meanwhile, the Kenya Ministry of Industry developed a battery re-import policy, all batteries must submit the relevant import permit.

       Kenya is the only battery manufacturer – Eveready East Africa’s welcome. Company has said that, due to the impact of counterfeit and shoddy products, the company an annual loss of more than 300 million Kenyan shillings (about 3.75 million U.S. dollars). Last year, the company had to close three production lines, lay off 400 people.

       At the same time head of Kenya’s Ministry of Industry revealed that, the government encouraged the import of acceptable quality batteries with local companies to compete in the market.

I have a 2006 Toyota Prius and the fuel indicator has an eight bar indicator for gas level. I also reset my trip meter after I fill up. And here’s where I think Toyota has missed the mark. I can go upwards of 120 miles and the gas meter still shows FULL, all 8 bars are still lit.

The car actually gets around 340-370 to a ten gallon tank. I average 38 mpg combined, even when I’m driving pretty aggressively. So, at the top of the gauge the measure is useless. But as the car moves closer to that magic 340-350 range the lights practically go out at in pairs. And if you see that last LED marker flash and the “add fuel” message on the dash, DO NOT PASS ANOTHER STATION. Get gas immediately.

So the fuel gauge is useless in the Prius. I know I get near 350 miles per tank with a gallon or so to spare. And the only indicator that causes me to take action is the flashing light, and if I have let the fuel get THAT LOW then it is an idiot light.

My laptop battery has similar issues.

When unplugged, my laptop does its best to calculate time remaining to standby. And the accuracy of the minutes to black is less important than the final “please plug in your laptop to avoid standby” message. Or the equivalent of the flashing “add fuel” message.

So in the real world my laptop with a 2.4 Intel Core Duo 2 gets approximately three to three-and-a-half hours on a full, overnight, charge. But the real measure, the real indicator I look for is that final “add fuel” warning.

Now, I am waiting with anticipation for a new laptop with an “enhanced” Li battery. Advertised and marketed at eight hours battery life, I am not so concerned or worried about “exactly” how long the battery will last, but more about how much additional warning I will have between when the battery says, “add fuel” and when the machine powers down in the middle of my Spore victory dance.

In terms of reporting battery performance, doesn’t some of the problem originate with the battery itself? Does an ATI battery and a Sony battery and a who-knows-what-brand battery all perform the same?

And what I learned recently in doing some “battery” research is, that heat is a bigger issue for Li batteries than anything else. So even in standby, if your Li battery and laptop are in a hot car with the windows rolled up, the battery will drain much faster than if it were on a shaded table in a coffee shop.

FACT: Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

I would like to see battery ratings gain more reputable metrics and here are some things I’d like to see:

I want the battery to last a long time (anything beyond 3 or so hours is pretty good, but I don’t travel a lot.);

I want the battery to not die prematurely (1 – 1.5 years seems like a reasonable amount of time before a replacement battery is necessary.);

But, more important to me than any spec (3DMark06 or MMO7) is this:

I’d really really, really like the battery to be GREEN. Less lead, less bad stuff, less waste.

Then we should really think about how to cool the battery better, so my palms aren’t on fire atop my 140 degree, and my thighs aren’t blistering red. If we can keep it cool, while under duress (like when running 3DMark06 benchmark), guess what? The battery performs better and lasts longer.

Now, back to cars for a second, I understand that the Prius outside the US has been offered with an EV override button that forces the car to use more electric power than it does in “normal” mode. It was taken off the US models by pressure from somewhere. (Not hard to imagine where that lobbying pressure came from.)

So with my laptop I would often hit the “TURBO” switch to keep the machine running at top performance even if that meant having to keep it plugged in. But I would like an “ECO” mode as well.

The upcoming 2010 Prius comes with three modes including “EV.”

By all means, let’s keep getting better and honest about our metrics. But let’s not obsess about dell Inspiron E1505 battery,dell Inspiron E1705 battery. Quite frankly, even if you tried to explain it to me, I don’t know what that 4 point 3DMark06-spread means in terms of actual battery time.

So when manufacturer says the new laptop will get 8-hours runtime (or is it 12?) I don’t really know what that means. Will my Prius really get 42 city 48 hwy? I don’t care. But when that “add fuel” message pops up on my laptop or my Prius, then I will sit up and take immediate action.

Dell said that since the narrowing of the global supply of laptop batteries, sales of Dell laptops have emerged in the late different circumstances, the situation above would cost Dell laptop.
Earlier in March, reports Reuters news agency noted that South Korea’s LG Chemical factory fire affected laptops used in the global supply of lithium batteries. In laptops and other devices used in the manufacturers of lithium batteries in the industry have been affected.

Dell has acknowledged the incident had affected the company supply chain mobile. Although Dell laptop has increased the price of spare and replacement batteries. But the battery voltage supply makes the laptop battery and could be further improved and the prices on the overall price of the laptop.

It is reported that Dell has been to facilitate existing providers and seek more sources of supply, and find new qualified suppliers to replenish the supply. Dell is still being studied in the same time, other new technologies.
Meanwhile, Sanyo, Panasonic manufacturer of laptop batteries, has invested hundreds of millions of dollars the United States also said that the expansion and further work on the portable battery plant is scheduled for the second half of 2009, the global shortage of batteries for laptops will be part of the problem.

Dell at the same time, said that during the Beijing Olympics because of traffic control, the public and delays in product delivery may occur. However, Dell has made an application for special permit cargo of motor vehicles and increase the capacity of Beijing local delivery and distribution and frequency in the affected during the 24-hours service delivery and the creation of five cargo point to mention to meet customer requirements for emergency orders.
