About Electric Car Battery and its role in EV

If you want to run an electric car it’s important for them to have a battery as battery is the life of BEV or Battery Electric Vehicle. Without a battery, you cannot run an electric vehicle. So it’s important to know more about electric car batteries. You can know the battery system is used, depending on the car. Different batteries are used for different cars. You can opt for electric car insurance at Finserv MARKETS. 

Type of batteries used in electric vehicles

There are various kinds of electric batteries available. Electric batteries are different from SLI or starting, lightning and ignition batteries. SLI batteries are mostly used in petrol and diesel cars. Batteries like this run for a longer time and are more sustainable. They even give more power.

Following are the types of batteries used in electric cars:

There are three types of electric batteries available. They are

Lithium-Ion (Li-On)

Nickel-Metal Hybrid (NiMH)

Lead Acid (SLA)

Lithium-Ion Battery (Li-On)

This kind of battery is used very commonly in portable electronic devices, which is why these batteries can be a bit familiar to us. They are also more efficient and also the most widely used batteries. The only difference between using the battery in an electronic device and an electric car is the size of the battery. Lithium-Ion Battery (Li-On) is also known as a traction battery pack. The power to weight ratio is high in Li-On batteries. This ratio is an important factor when considering the type of batteries you are looking for. Electric cars with Li-On batteries are highly energy-efficient than the other batteries. They also perform well in high temperatures. If the battery weight is smaller, it can run for a longer time. Li-On batteries consist of parts that can be recycled, so they are especially good for those who want an environmentally friendly option. Additionally, they are also budget-friendly and go easy on your pockets.

Following are different types of Li-On batteries:

Lithium Iron Phosphate(LiFePO4) — LFP

Lithium Titanate (Li2TiO3) — LTO

Lithium Manganese Oxide (LiMn2O4) — LMO

Lithium Cobalt Oxide(LiCoO2) — LCO

Hybrid Nickel-Metal (NiMH) Batteries

Hybrid Nickel-Metal (NiMH) batteries are popularly used in Hybrid electric vehicles. They are also used in electric vehicles or BEV (Battery Electric vehicles). Depending on engine speed, wheels and regenerative braking you can use Hybrid Nickel-Metal Batteries. NiMH batteries don’t get their power from outside. However, when it comes to running for a longer time NiMH batteries are better than Lithium or Li-ON batteries and SLA batteries. They are more long-lasting than these batteries. When used correctly, NiMH batteries are tolerant and safe to use. They are comparatively much expensive and have a high self-discharge rate. They also generate significant heat at high temperatures. These qualities make NiMH batteries more efficient than the other batteries as compared to similar batteries.

SLA or Lead Acid-Batteries

SLA or Sealed Lead Acid are one of the oldest rechargeable batteries. They are compared to Lithium and NiMH batteries, much heavier in weight. However, they are relatively cheaper than these batteries. In order to make SLA batteries better, they are now coming up with batteries with more capacity. As of now, SLA batteries are used as the secondary storage system in commercial cars.

Things to consider while choosing the best battery type

Following are the factors that need to be considered when choosing a battery for your electric vehicle:

  • Lifespan

It’s important to check the lifespan of the battery before buying it. Every battery has a different lifespan. You can look for a battery that has a lifespan of 8 years or 160,000 km.

  • Safety of the battery and the vehicle

It’s important to choose a battery that is safe and secure for the vehicle. You may want to take all steps properly in order to ensure the safety of the car or any other vehicle. An electric vehicle takes a lot of energy, hence you should buy the right one for your vehicle.

  • Cost

Before buying the battery, compare the price of the vehicles and then go for the one you found the best. As compared to a small ICE, vehicle EV have the same cost of batteries.


Electric vehicles are more efficient than normal vehicles. They are also eco-friendly and recharging them is cheaper than filling petrol or diesel in the normal vehicle. When buying an electric vehicle, it’s important to check its efficiency, cost, safety and life span. Finserv MARKETS has many advantages to offer you.
