The massive pack of batteries in Electric Vehicles is probably the most expensive component in these new forms of transport and this has put the breaks on their performance to  increase their usable lifespan.

Lithium Ion batteries, the same material that is used in your portable devices like cameras and notepads, does degrade under extreme usage. The main factor here is what is called the “Deep Discharge”, using the batteries until their capacity is nearly zero.

Electric Vehicle Manufacturers have implemented limits on the amount of discharge  the Lithium Ion battery is allowed. While the life of the battery is extended this means the performance, and specifically the driving mileage is reduced before you have to pop in to the nearest charging station.  Can you imaging filling up your combustion engine driven car and only being able to use half a tank of gas before you need to fill up again. This is the situation for electric.

That is the bad news, there is good news of course. Using the data from the usage of the current electric cars manufactures have realized that they can release some of the limits imposed on the battery packs. The outcome is two fold here, the first is that using the same battery pack, your electric vehicle will be able to vastly increase their range. Secondly if range is not a factor then the size and weight of the battery can be perhaps halved.

The packs are costly and heavy, being able to reduce cost means much cheaper cars on the road and the added bonus means less eight that your car has to carry around. Those early generation vehicles like all first generation goods will lead the way to much better descendants. We just have to think about the performance and size of recent electrical devices like television screens and computer specifications. The battery packs will improve vastly and who knows how far our electric car will take us in the next decade.

Clean Energy production in the home is dynamic and for the home user the need for storage devices for that excess electricity has been a problem. Large banks of lead-acid batteries can be costly and take up too much space. The Li-on battery are the high capacity storage that we have in out electronic equipment – mobile phones, laptops and digital cameras.

Scaling up the battery is not easy, heat is the major problem and it now seems that Panasonic may have all that solved. In a few years we could have the promise of large capacity rechargeable batteries that will be suitable for home use.

Electrical generation by solar panels can be stored easily now for later use, although any from of electricity can be stored not just what is generated by your renewable source. Occasionally the utility supply has its little problems and the lights go out. The high capacity battery pack will take care of your needs till the power comes back on.  Charge up your battery on cheap low rate  electricity at night and use it to power your home during that day when the rates go to peak cost.

The uses are not only limited to the home. Electric vehicles which are going to be commonplace by the end of this decade are ideal candidates for these.

The technology of electrical storage should see many developments in both home use and for commercial use. The current problems with renewable energy production like solar and wind is that its not always on. The wind is not always blowing and solar has that little problem with darkness. High capacity and safe batteries could keep that energy stored for when it is needed.
