How Will Toshiba’s SCiB Battery Technology Impact EVs?
Toshiba announced Monday in this press release the commercial release of the SCiB (Super Charge Ion Battery). The battery’s selling points are that it can recharge to 90% capacity in less than five minutes, it’s safe and it has a 10-year lifespan. It can also operate down to -30 celcius (-22F). This means that it would apply well to an Electric Vehicle type application, but is a five minute charge feasible for an EV?
One of the major roadblocks to widespread EV adoption is the “gas-up” factor. Consumers want the ability to be able to do a quick recharge when they are on the go. Finally, we have a battery which offers exactly that. It takes about five minutes to fill up a tank, so it could be said that the times are comparable. There is just one little problem with this. Physics.
Let’s use a real production car for an example. Say for instance, we fitted a new Tesla Roadster with SCiB batteries. Could we actually perform a 5 minute charge? The Roadster’s efficiency is reported as 133 Wh/km (4.7 mi/kWh). This means that fully refueling from a 300 mile drive would require around 63kWh of electricity. Multiply by .9 to get a 90% recharge (as Toshiba states is the 5 minute charge) and you have 56.7kWh. Multiply that by 12 to get the amount of kW required for a 5 minute charge. That’s 680kW. Regardless of what you may know about electricity, that’s a whole lot of it.
Replacement Laptop Battery For TOSHIBA PA3399U-2BRS
- Part No: PA3399U-2BRS
- Battery Type: Li-ion
- Volt: 10.8 V
- Capacity: 8800mAh
- Weight: 725.76g
- Dimension: 206.60×91.40×26.40mm
- Color: Black
- Promotion Price: AU $119.58 (inc. GST)
To actually feed the car 680kW, we need to select a usable voltage. The best that’s commercially available right now would be 480v or actually 220v if it’s household current. For the sake of argument let’s choose 480v. The size of the wire to transfer the energy is dependent on how many amps are going to flow through it. Amps are just watts divided by volts, so when we apply this we get 1416 amps. Technicalities aside, the wire would have to be something like 0/8AWG or about 2 inches in diameter to feed the current to the vehicle. Is this any more or less safe than filling a car with gas yourself? I guess it’s up to the engineers to tell us that.
Don’t misunderstand. This battery really is a great thing, but there are serious infrastructure issues to using it. Just one car charging, even for 5 minutes, at 680kW is pulling the same amount of power as 144 homes with air-conditioning on (which is about 40 amps at 110v).
I believe it’s possible to get proper electricity distribution infrastructure in place but it will require massive planning and cooperation between energy companies and energy distributors. The current substations just can’t feed that kind of electricity right now, even for a small number of drivers.
I do believe though that this battery could be successfully used for a 1 or 2 hour quick charge. The numbers work out much better in favor of the existing power grids for that. While it doesn’t necessarily solve the road tripper’s issues of needing a 5-10 minute recharge every 200-300 miles, it will help the majority of EV skeptics in reassuring that a pure EV is fairly capable of delivering extended service without needing a full day of recharge time.
Without a published energy density, it’s difficult to say if these batteries are light and powerful enough for every day EV use. Even so, they are a step in the right direction and could be fantastic for general use once the power grids can deliver the amps. Until then, we will have to depend on the plug-in hybrid to be the duct-tape helping hold the existing gasoline distribution networks together with the electric future.

Green Laptops: The Way to the Future
Concerns over global warming and its effect to the environment have put pressure on every industry to clamp down on its energy consumption. For the computer makers and users alike, the “green” laptops are the future in mobile computing.
Since energy conservation is one prime adaptation measure that needs to be done, laptops that consume less energy are slowly gaining popularity. The lists of considerations in purchasing a laptop has gone longer and now includes energy efficiency. An ideal laptop would be one that consumes less energy, along with portability, connectivity and processing capabilities.
So what features does the green laptop of the feature need to have?
Energy Efficiency
We all know that laptops are trending towards smaller, sleeker and lighter proportions. Now, the trend towards greener performance is gaining ground. This means lesser energy consumption, longer battery life, and even alternative power sources.
There are now a lot of technologies that aims to minimizing energy wastage and consumption. The interventions include tweaking internal systems to automatically shut down unnecessary computer activities that waste energy such as the auto switch to hibernate mode when inactivity is noticed. The choice of display technology is also considered. Right now, the LCDs are the most popular. But an emerging alternative is being pushed. This is the OLED (Organic Light emitting Diode). It is said to draw less power and might have good aesthetic effects on the screen.
Solar-powered options and hybrids are also said to be in the works. Some promising tests have been shown to produce feasible and in fact cheaper models. Certainly, when the going gets tough, the research and design coverage and tasks become less mundane. While companies spend much resources to improving aesthetics, a number are now beefing up their research on greener mobile technologies. This is a good sign indeed.
Disposability and Recycling
It was surmised that the laptops disposed by China in 5 years time is enough to cover the whole of Netherlands with laptop scraps. This brings us to the issue of disposability.
First, a laptop has to be hardy enough to warrant that you do not need dispose and acquire new ones very often. Secondly, proper recycling and dumping options for gadgets, including laptops need to be addressed. This could take the form of manufacturers owning the responsibilities of recycling and disposing, especially those that are very hard to dispose. A number of companies already have recycling and disposal services for its customers. There are also big name non-profits that do the job.
It would be of help of techies themselves add pressure to manufacturers by refusing to buy gadgets without disposal services being guaranteed upon purchase. This, of course, would add up to the price of the merchandise. But that would be a small sacrifice for the benefit of the world.
Another option for techies would be to donate still-operational but old laptops to charitable organizations that can put it to better reuse.
Sustainable and Environment-Friendly Packaging
Another area that is fast gaining ground is the search for organic, bio-degradable and less costly packaging. Manufacturers themselves are hard into this and you could already see improvements in the newer products. A government mandate would add up to speeding the transition to more eco-friendly and biodegradable packaging materials. GP

Dell XPS M1210 AC Adapter how to work, Dell XPS M1210 AC Adapter review
Consider buying a Dell XPS M1210 AC Adapter. These are available at most major electronics outlets, will work for a variety of voltages, and come equipped with several sizes of plug tips to fit your computer. However, you will still want to read the packaging carefully and make sure that your computer is on the list of machines the laptop ac adapter will work for. If there is no list by brand, compare the replacement to your old Dell XPS M1210 AC Adapter, looking at plug tip size, DC output and AC input numbers.
Naturally occurring forces in the universe can cause particles to move. One of these forces is “electromagnetism.” This phenomenon is the reason why charged particles can also make electric current, such as lightning, but people cannot use lightning as it is too unpredictable. To make man-made electricity, one need only have a Dell ac adapter to redirect nature’s electromagnetic field to generate either alternating or direct current. Some experts regard electricity as “temperamental,” so you need a device to maintain this energy interflow safely.
The figure shows the schematic diagram of a very basic DC circuit. It consists of nothing more than a source (a producer of electrical energy) and a load (whatever is to be powered by that electrical energy). The source can be any electrical source: a chemical battery, a laptop ac adapter, a mechanical generator, or any other possible continuous source of electrical energy. For simplicity, we represent the source in this figure as a battery.
To make an electrical gadget work, you have to direct electricity into it, and keep it there until you do not want to use it anymore. Power stations generally send alternating current through power lines. It is the easiest way to send energy to a home, apartment or office building. Most devices utilize direct current. A transformer is typically responsible for changing the Dell ac adpater voltage that runs from an outlet. A common Dell XPS M1210 AC Adapter is also a type of transformer, but it does not change the amount of electricity, just the direction in which it flows back and forth through a wire or adjoining devices.
