Batteries for Battery Powered Cars Are More Environmentally Friendly Than Expected

It is not an easy task to compare the environmental effects of battery powered cars to those caused by conventionally fuelled automobiles. The degree to which manufacture, usage and disposal of the batteries used to store the necessary electrical energy are detrimental to the environment is not exactly known. Now, for the first time, a team of Empa scientists have made a detailed life cycle assessment (LCA) or ecobalance of lithium-ion (Li-ion) batteries, in particular the chemically improved (i.e. more environmentally friendly) version of the ones most frequently used in electric vehicles.

The investigation shows that if the power used to charge the battery is not derived from purely hydroelectric sources, then it is primarily the operation of the electric car, which has an environmental impact, exactly as is the case with conventionally fuelled automobiles. The size of the environmental footprint depends on which sources of power are used to "fuel" the e-mobile. The Li-ion battery itself has, in contrast, a limited effect on the LCA of the electric vehicle. This is contrary to initial expectations that the manufacture of the batteries could negate the advantages of the electric drive.
The environmental impact of batteries for electric vehicles
Battery powered electric cars are often promoted as the ideal solution to the challenges of future mobility, since they produce no exhaust gases in operation. Li-ion batteries have established themselves over competing lead-acid and nickel metal-hydride (NiMH) types because they are lighter and can store more energy. Li-ion batteries are also basically maintenance-free, display no memory effect (loss of capacity when repeatedly charged after partial discharge), have a low self-discharge rate and are regarded as safe and long-lived. For these reasons they find use in many products such as laptop computers. But are they also environmentally friendly?
Researchers at Empa's "Technology and Society Laboratory" decided to find out for sure. They calculated the ecological footprints of electric cars fitted with Li-ion batteries, taking into account all possible relevant factors, from those associated with the production of individual parts all the way through to the scrapping of the vehicle and the disposal of the remains, including the operation of the vehicle during its lifetime. Data with which to evaluate the rechargeable batteries was not available and had to be obtained specifically for this purpose. In doing so the researchers made intentionally unfavorable assumptions. One such was to ignore the fact that after use in a car, a battery might well be used in a stationary setting for other purposes. Other relevant LCA information was obtained from the "ecoinvent" database, managed by Empa. The electric vehicles evaluated were equivalent in size and performance to a VW Golf, and the power used to charge the batteries was assumed to be derived from sources representing an average European electricity mix.
A new petrol-engined car, meeting the Euro 5 emission regulations, was used for comparison. It consumes on average 5.2 liter per 100 kilometers when put through the New European Driving Cycle (NEDC), a value significantly lower than the European average. In this respect, therefore, the conventional vehicle belongs to the best of its class on the market.
More a question of the power source rather than the battery
The study shows that the electric car's buy battery drive is in fact only a moderate environmental burden. At most only 15 per cent of the total burden can be ascribed to the bosch drill battery (including its manufacture, maintenance and disposal). Half of this figure, that is about 7.5 per cent of the total environmental burden, occurs during the refining and manufacture of the battery's raw materials, copper and aluminium. The production of the lithium, in the other hand, is responsible for only 2.3 per cent of the total. "Lithium-ion rechargeable batteries are not as bad as previously assumed," according to Dominic Notter, coauthor of the study which has just been published in the scientific journal "Environmental Science & Technology."
The outlook is not as rosy when one looks at the operation of an electric vehicle over an expected lifetime of 150'000 kilometers. The greatest ecological impact is caused by the regular recharging of the makita drill battery, that is, the "fuel" of the e-car. "Refueling" with electricity sourced from a mixture of atomic, coal-fired and hydroelectric power tool battery stations, as is usual in Europe, results in three times as much pollution as from the Li-ion battery alone. It is therefore worth considering alternative power sources: If the electricity is generated exclusively by coal-fired power stations, the ecobalance worsens by another 13 per cent. If, on the other hand, the power is purely hydroelectric, then this figure improves by no less than 40 per cent.
The conclusion drawn by the Empa team: a petrol-engined car must consume between three and four liters per 100 kilometers (or about 70 mpg) in order to be as environmentally friendly as the e-car studied, powered with Li-ion batteries and charged with a typical European electricity mix.

Electric Car Batteries are Greener than Expected


The lithium ion (Li-ion) batteries that will be powering the electric cars of tomorrow are much greener than originally expected, according to new research conducted.
Much has been made of whether electric cars will actually be the saviour of our future, or whether they are just redistributing the environmental damage to other aspects, like the production and disposal zv5000 battery. One of the major concerns was how the lithium ion battery would affect the environment.
In the end, the results of the study were surprising.
“Lithium-ion rechargeable batteries are not as bad as previously assumed,” according to Dominic Notter, coauthor of the study which has just been published in the scientific journal “Environmental Science & Technology”.
A team of EMPA (Swiss Federal Laboratories for Materials Testing and Research) scientists created a life cycle assessment of lithium ion batteries, focusing on the most commonly lithium dell inspiron 1525 battery used in electric cars.
What they found was that in the long run the lithium ion battery only held a 15% burden on the environment, with half of that percentage being given over to the manufacture and refinement of the battery’s raw materials, copper and aluminium. The production of the lithium on the other hand is only responsible for 2.3% of the total.
The greatest impact on the environment comes not from the car itself but rather the method with which the car is recharged, or fuelled. Charging the battery from a mixture of sources, primarily coal-fired, atomic and hydroelectric, results in three times as much pollution as from the hp dv6000 battery alone. If the electricity generated to recharge the car is solely from coal-fired power stations the ecobalance worsens by another 13%.
The conclusions reached by the EMPA team were that a petrol fuelled car must consume between three and four litres per 100 kilometres (or 70 miles per gallon) in order to be as environmentally friendly as the electronic car studied. Additionally, alternative energy sources must be considered and implemented if the electric vehicle is to be of any substantial help in minimizing the pollution pumped into the atmosphere.

Interstate Batteries Offers Battery Care Tips During Sizzlin' Summer Heat Wave

Did you know that more automobile batteries fail in July than in January? Summer heat is actually harder on a battery than winter cold. With record heat sweeping across the country, Interstate Batteries encourages motorists to protect and care for that part of the vehicle a driver depends on the most every day.Toshiba laptop battery

"The corrosion factor within a battery is accelerated by extreme temperatures, especially heat," said Interstate Batteries Technical Service Manager Gale Kimbrough. "Battery Temperatures under the hood of a car can reach 175 to 200 degrees in extreme heat conditions. This is why it is very important for motorists to take the necessary precautions of having their vehicle battery checked on a regular basis.sony laptop battery

Interstate Batteries has some helpful guidelines to follow when caring for your automobile battery:asus laptop battery

When working with your laptop batteries, always wear protective eyewear, remove all jewelry and wear long sleeves to protect your arms from an explosion of battery acid.
Do a visual inspection to see if the notebook battery case is showing signs of extreme bulging, cracked or leaking. If it is, it's time to replace it.
Clean up the connections by removing any corrosion, lead oxidation, paint or rust from the top of the battery with a scouring pad or brass brush. Be sure to brush the corrosion away from you.
If your battery has removable filler caps, open the caps and check the water level in each cell.
Make sure the plates are at least half covered. This prevents sulfation and reduces the possibility of an internal battery explosion.dell laptop battery
If the water level is low, add distilled water (avoid tap water) until the plates are covered.
Avoid overfilling, especially in hot weather, because the heat can cause the solution inside to expand and overflow.compaq laptop battery.
Have your battery and electrical system professionally tested every three to six months and especially prior to heading out on a trip.
In just 30 seconds, Interstate All Battery Center locations can provide motorists with a free printout analysis of their vehicle battery condition.

Put your computer to sleep whenever you're not actively using it, like when you're on the phone, in the bathroom, or walking the dog.
* Eject optical disks. They spin, taking power, even when they're not actively being used.
* Have lots of RAM installed. This helps prevent excessive virtual memory use (virtual memory is hard drive space that's turned into "virtual" RAM. When the computer needs more RAM than is physically installed, it'll dip into virtual memory reserves, and cause increased disk activity. For this reason, avoid invoking dashboard for its excessive memory use; consider using activity monitor to kill the dock process, which owns Dashboard. If you've invoked Dashboard, killing the Dock will free up all the memory it used. Consider disabling Spotlight as well because its indexing is both processor- and disk-intensive.

* Use your iPod for music. iTunes keeps the hard drive working.

* Type in TextEdit, not Word. Word's autosave feature spins up the hard drive all the time; TextEdit does no such thing.

* Don't keep unused Applications running in the background.

Laptop Battery Life,Things You Do Not Know

Laptop battery life,this is a popular topics between laptop owners,exactly,they often discussed the life of laptop battery in the related forums.Whatever type of battery, or how well the manufacturer has a reputation,proper care and maintenance is always necessary if you want your laptop battery more efficient.

In more common terms you should know if you need to know the problems with laptop battery is the depth of discharge. Commonly referred to as the Department of Defense, the depth of discharge used for the rules on the scope of the battery dies before it is plugged into the slot. Some people believe that working with laptops and are fully connected to the power supply. In such cases, the depth of discharge is almost zero. On the other hand, some people sometimes use the batteries until they are completely empty. The most common is what lies between them. The depth of the common discharge ranging from 66% to 76%.

After something like the levels charged and discharged,you should also look at laptop temperature. When you use your laptop on the work is very hot. Once the laptop gets hot, it affects the efficiency of your laptop, and thus it consumes more energy than needed to reduce the battery from the laptop. This is the result of internal resistance. It is desirable that the replacement laptop battery will not heat above 30 degrees Celsius. To achieve this, it is recommended to avoid some common mistakes, like setting the notebook on your lap or put it on a soft surface, such as pillows.

Another sentence, you may be of interest, the charge cycle. This is the time between battery is empty, then reload. The implementation of a battery down does not refer to lead to 0%. No, he refers to the removal of the battery at about 66% - 70% level. When the battery capacity to 90%, a cycle is completed is increased.

According to the manufacturer, the laptop batteries have different capacities to carry out their duties. To avoid unwanted pregnancies, make sure that you have an extra battery, which can be useful if you juice and have no where to get some cargo. Make sure one of you surely extend the life of the laptop battery.
