How Do Electric Car Batteries Work?

 

Perhaps you have asked yourself the question, "How the heck can electric cars run for numerous miles with just a pair of batteries?" Needless to say, the curiosity is pretty common among vehicle owners. Everybody experienced a dead battery one or more times in their lifetime, no?

Perhaps you have left the car lights on for 2 hours you know that the car battery can become extremely weak or die inside a short period of time if the car just isn't running! So how could you possibly have the same batteries power the entire 2000 lb car for countless miles?

To answer this I'm going to point out some important differences between traditional gasoline powered cars and the new electric cars that you've heard so much about. The main difference lies entirely from the batteries of those cars.

In relation to mass producing a product such as a battery for a car the producer has to consider the expense of producing. It's a crucial factor that is always taken into account, which explains why most manufacturers use limited technology to produce the battery that runs your gasoline car. The actual fact of the matter is, a gasoline car only uses a battery to start the auto. As soon as your engine starts running the alternator starts and your battery actually starts regaining its charge as opposed to losing it.

An electric car doesn't have an alternator that recharges battery thus having to rely positioned on the batteries since the energy source. For this reason, the batteries within electric cars use top-notch today's technology that's not used in traditional car batteries. By way of example, traditional car batteries have its electrolytes in a liquid form while electric car batteries contain it in gel form. Because it is in gel form, manufacturers can produce the batteries in different orientation they want. This helps produce the maximum number of cells in only a little space. Once you pack those highly condensed batteries into a power car it allows the car to produce better mileage in one charge.

Electric cars have 2 kinds of batteries: the VRAL, and GEL. The GEL batteries use VRAL technology but it is very advanced and require much maintenance. With advanced sealing technology it's almost impossible to spill GEL. However, the sole downside to GEL batteries will be the constant requirement to release and recharge it. For normal commuters this isn't a large problem. However, irregular drivers will see it difficult to always discharge and recharge the battery, thus wearing it out a lot more quickly.

The industry is making advancements for the usage of Lithium-Ion batteries. The Li-Ion batteries have been about for decades; however, we couldn't put its high effectiveness to use in cars: up to now, that is. New technology finally allows us research, experiment, and provide highly efficient Lithium-Ion batteries that are small in size but pack a lot stronger punch. These batteries don't contain any liquid thus allowing users to operate a vehicle their cars to get a much longer time than liquid or GEL batteries.
