The battery is the most essential component of an electric vehicle. The battery technology is used to store the entire charge or energy required to power electric cars. Hence these batteries must be robust, long-lasting, and much store significant amount of charge to give a more extensive range for an EV. The batteries used in EVs consist of numerous small rechargeable cells mounted on the lower platform of an electric motor vehicle. Therefore, the battery pack can cover approximately 60% of the entire usable area in the EVs. 

There are numerous varieties of batteries that were earlier used in electric vehicles or are presently found. The most common of them are Lithium-ion batteries, Nickel Cadmium Cells, and Nickel Metal Hydride batteries. These are the most trusted and tested types of batteries. But, out of these Lithium-ion (Li-ion) are found in most of the presently manufactured fully electric vehicles. The Li-ion cells are much lighter in weight and can store a much more substantial amount of charge than other batteries. Hence the EV manufacturers prefer using Li-ion batteries to achieve a significant range for an EV and also reducing the overall curb weight. 

Life of the Batteries Used in Electric Vehicles

Actual usage of Li-ion batteries for increasing efficiency
The batteries in the electric vehicles are optimized to work within a Battery Buffer or a defined range. It helps in less degradation of batteries.

Since the batteries are one of the most expensive components in an electric vehicle, the buyers are concerned about battery life. After much research and screenings, the manufacturers decided to use battery packs to power the EV. One primary reason was that batteries could last much longer if used with proper optimizations. The majority of significant EV manufacturers give the warranty of a minimum of eight years or 100,000 miles. But the Li-ion batteries are meant to be used for many more years without any efficiency loss.

Many consumers wonder if the same Li-ion batteries are used in mobile phones or laptops, why do they degrade within a couple of years. Here comes the concept of the Charging Cycle. The people generally charge their appliance up to 100% battery level and use until the battery is completely exhausted. This type of usage is the most intensive use of any Li-ion cells, which will result in the batteries’ degradation. Wherein the Li-ion batteries of the electric vehicles are optimized for efficient usage. The EV manufacturers set a battery buffer, which does not allow the battery to charge up to 100% and discharge to 0%.

Are there any Present Developments Going on in the Field of Battery Technology?

Can solid-state batteries replace Li-ion batteries?
Many companies are working on Solid-state batteries which could provide larger energy storage capacity and more significant EV range in a single charge.

Overall, the well-optimized Li-ion batteries can work smoothly and efficiently for approximately more than 15 years. There can be some cases where the Li-ion batteries lose around 10% of the charge retention capacity and slightly decreases the range of the motor vehicle. But this happens very rarely or when the buyer mishandles the charging of the electric vehicle. At present, both Indian and Foreign Automotive companies are researching on improving the Battery Technology and developing more efficient Li-ion batteries that could last for greater miles.

Delta Moto Corp is an Indian origin manufacturing company, that promises to provide affordable E-Mobility solutions to expand the Electric-Mobility in the country. The company builds high-quality battery technology, smart dashboards, EV powertrains, and essential components for EVs. Many companies are also developing recycling and reusing batteries, that could be repurposed after using in EVs. These degraded batteries can be refurbished and used in the manufacturing plants, houses, or other vital locations. Hence it will result in lowering the expenses and enhancing the life of batteries.

Therefore, EV batteries have a long life and can be used for years if used properly. The cells used in electric vehicles are durable, robust, and are lighter in weight. It directly affects the weight of the car, which results in better performance. The battery packs used in the EVs are among the vital components; hence, the EV industry is also focusing on expanding the Battery Technology manufacturing around the globe. The advancement in technology with a reduction in prices will positively affect the growth of Electric Mobility in the World.
