Most governments today are promoting the use of electric vehicles to reduce the carbon footprint and to try to save on fossil fuels. As a result, battery manufacturers are putting a lot of efforts and work to find out the best solution to power electric automobiles.
As of today, the best option we have is to use Lithium Ion batteries for cars. Since it is the ideal power source for electric cars even though newer NiMH power cells can be a cheaper and safer option.
Hybrid and electric cars like Tesla Roadster and Smart Fortwo ED are proof that Li-ion batteries got what it takes to be the best suitable power source. However, battery manufacturers are still looking if there are other solutions that can be safer and better.
In this article, we are going to take a look at the significant qualities a battery should have to be an ideal power source for electric vehicles. This will give us an idea why Lithium Ion batteries remain as the best suitable option to power electric automobiles.
How Electric Cars Different from the Traditional Cars
Electric automobiles are different from the traditional vehicles running through fuel. They are considered to the future of automobiles and sometimes referred as “green” cars because they are more environmentally friendly.
Unlike the conventional automobiles that burn fuel to generate combustion, electric vehicles rely on battery-stored energy to run one or multiple electric motors.
Battery-powered vehicles have different demands because of their unique engineering. They mainly rely on their batteries to run and supply enough power for the entire electrical grid of the vehicle.
Because these vehicles rely primarily on batteries, the power cells that they need should have specific qualities that will allow them to keep up with the huge demands of the vehicle.
Important Battery Qualities to Power Electric Cars
To power electric vehicles, battery manufacturers are putting a lot of work in designing the power cells. They provide emphasis on the important areas required to handle the tough task of running an entire vehicle.
Focusing on strengthening these significant areas enable the batteries to keep up with the demands of the vehicle and run it.
To find out what are these important qualities, they are listed and explained below:
● Safety – When it comes to electric vehicles having bad publicity due to a single incident with regards to the safety of its power source can instantly result in a negative impact on the manufacturers. That’s why battery manufacturers are prioritizing this aspect. The batteries used to power electric vehicles feature a thermal runway that can cause serious accidents. This is why manufacturers should carefully design heavy-duty battery housings and safe circuits to eliminate the risk of unwanted accidents. The batteries that will power the electric vehicles should be 100% safe to use to avoid turning the public against electric vehicles.
● Life Expectancy – Electric vehicle batteries should also have the toughness and durability to last for at least eight to ten years. Otherwise, the public won’t consider investing in electric vehicles because they can be very expensive. Another concern is the battery’s tendency to lose capacity over time or in drastic weather conditions because it will also affect the performance of the vehicle. Most battery manufacturers address the capacity loss issue by producing larger power cells to provide some room for battery degradation and keep up with the promised battery life expectancy.
● Battery Performance – The performance of the battery is another important quality an electric car power cell should have. It has to be designed to provide optimum performance in hot or cold climates. It also has to have the ability to moderate its own temperature to keep up with the demands of the vehicle even at high or low temperatures.
● Specific Energy – This battery information indicates the amount of energy the power cell can store in terms of weight which also reflects the driving range. Keep in mind that compared to the energy fossil fuels can generate, a battery is 99% short. So in terms of output per weight, the capability of the battery to store energy should be doubled or quadrupled for the battery to keep up with the output of a conventional engine.
Lithium-ion batteries for cars is the only option that will allow us to drive electric vehicles. This is because Li-ion batteries are the only type of power cell that has the qualities listed above. It may come up short on some of them, but it is the only type of battery that can offer them.
