How to Select Battery for Electric Car?

The automotive industry is currently experiencing an electric car craze, and this trend could continue to gain traction. Back in the day, a dozen or so companies made electric cars, and the market for them was booming. However, the arrival of well-known players like Tesla altered the playing field.

Owners of electric vehicles care most about two things: battery life and driving range. The average person has little to no idea how to monitor battery life or extend its lifespan.

However, calculating the required battery capacity isn’t the only step in the process. The size and location of the battery, the total mass of the automobile, and the number and variety of controls it needs are also important factors to think about.

The battery technology used in EVs is constantly improving and developing. You can’t get the most out of your electric car if you don’t know how to pick the best battery for it.

Here’s a full explanation of how to select an electric car battery.

How Does an Electric Car Battery Work?

Batteries are essential to the operation of an electric car. In the absence of gasoline, it is what keeps you moving. A battery will eventually die.

To a large extent, this depends on the battery’s size, how often and how it is used, and how it is used. Additionally, your electric car’s batteries are its very essence.

You’ve probably heard about electric automobiles, but you may be wondering, “How does a battery in an electric car even work?”

Electric vehicle batteries serve the same purpose as standard batteries. Electrochemical cells in a battery transform chemical energy into electricity.

Energy for an electric vehicle is stored in a battery, and that energy is derived from the actual motion of electrons. Electric current is generated when an electron flows across a metal wire filament connected to a high-voltage battery.

Charging a battery results in electric current because of the movement of electrons through a wire. Electricity can also be referred to as electric current.

Your car’s battery can be recharged in a number of ways, the most common of which are the movement of a motorized vehicle or the use of an alternative energy source like a wind turbine or solar panels.

What Type of Battery Is Used in an Electric Car?

The introduction of the battery changed the way we stored and used energy forever. It’s not hard to see how electric vehicles excel over their internal combustion-engine counterparts. However, there are some general things to keep in mind while shopping for an electric car battery.

People can now just plug in and use the electricity produced by an internal combustion engine. However, you’ll need a battery for this, so which battery do you recommend?

So now that we know why batteries are used in electric vehicles, let’s have a look at the various options.

1. Lithium-ion batteries

Most contemporary electric vehicles utilize lithium-ion battery packs. This battery technology is utilized in a wide range of electronic devices, including autos, notebooks, and mobile phones.

Compared to other battery types used for charging electric cars, their energy efficiency and temperature performance are significantly higher. This is a major perk that the vast majority of batteries don’t have.

In addition, lithium-ion batteries can tolerate a great deal of energy despite their light weight.

This battery can power your electric vehicle for 8 to 10 years in harsh conditions and 12 to 14 years in pleasant climates. Most of its components are recyclable, which is good for the planet.

This battery’s high performance may be maintained with minimal effort on your part, which is another plus. The cost of battery replacement is unnecessary.

The thousands of lithium-ion cells that make up the battery ensure a lengthy range between charges.

The most significant negative of these batteries is their potential to explode if you don’t handle them carefully when disassembling them.

2. Nickel-Metal Hydride Batteries

Nickel-metal hydride batteries are another common type. These batteries are most commonly used in hybrid vehicles, although they are also used in electric vehicles.

It has an advantage over lithium-ion due to its longer-lasting battery. Nothing, not even subzero temperatures, can dampen their performance.

However, similar to other battery types, this one has some limitations in terms of charging. The charging and discharging times are significantly longer as compared to Lithium-ion batteries.

The constant recharging and discharging they undergo necessitates their own cooling infrastructure. Big batteries are required to supply the required power, so portability becomes an issue.

Nickel-metal hydride batteries’ key advantage is that they may be recycled without much effort because of the high concentration of nickel inside them.

3. Lead Acid Batteries

Lead-acid batteries, which have liquid electrolytes and a lead storage component, allow electric vehicles to be recharged.

This battery type is superior to others used in electric vehicles in both price and capacity.

Lead-acid batteries are now solely utilized as a backup storage system to power other battery loads, therefore you’ll typically see them in commercial vehicles.

Its capacity is low because to design restrictions, but it is easy to produce and recycle.

On the other hand, it can be used to charge electric traction motors. Because this battery won’t ignite if you try to take it apart, it poses no fire threat.

The battery’s lifespan is less than that of lithium-ion and nickel-metal hydride alternatives, which is one of its main drawbacks. As a result, it is typically deemed unsuitable for use in electric vehicles because to its poor performance in the cold.

The model of the vehicle and the battery needs of the owner are two of the many considerations that should go into making the correct battery decision.

When choosing a battery, you’ll want to think about whether you want to go with a lead-acid, nickel-metal-hydride, or Lithium-ion one.

How to Choose an Electric Car Battery

There are a lot of concerns that come up when people decide to buy a new plug-in car. How far of a radius do I need? In what dimensions do you need this? Which is more important, speed or far-reaching effect?

We’ve put up this battery guide to address these concerns and more so you can shop with confidence.

1. Driving Range

The electric car battery you choose will be based on the driving range you need. If your car’s battery dies before you get there, it won’t do you much good.

The amount of energy stored in the battery of an electric vehicle is reported in kilowatt-hours (kWh), the same measurement used to determine the cost of electricity. How far you intend to drive between charges is a key factor in determining the size of the battery pack required for your electric vehicle.

Let’s take Tesla, a brand that has been receiving rave reviews, as an example. Tesla vehicles have a very low energy footprint, using only 0.2% of the energy needed to travel one kilometer. If you multiply this value (0.2) by the distance in kilometers you wish to travel, you will get an estimate of how much juice the battery will need to get you there.

Similarly, you can calculate how much juice your car’s battery needs to make it there.

2. Battery Space

Ideally, a battery’s capacity would be high enough that it could get you from A to B without stopping for a recharge. Hence, the bigger size of an electric car’s battery in comparison to a gasoline-powered vehicle.

Another factor to consider is the availability of physical space. This may have a role in deciding which battery brand to buy. The power source is stowed away in the floor of the internal carriage.

Knowing the kilowatt-hour (kWh) requirement for the battery makes it easy to determine how many battery modules must be connected in series to meet the demand.

When connecting these modules, make sure the rows are a multiple of the amount of modules you’ll have in parallel to avoid any problems.

By measuring the battery voltage in this way, you may get a reasonable idea of the battery’s total capacity and power. These formulas will be useful for that purpose:

Total Capacity = capacity per battery X of batteries linked in parallel X nominal voltage
Peak power = peak current per battery X number of batteries linked in parallel X nominal voltage
Continuous power = continuous current per battery X number of paralleled batteries X nominal voltage

3. Warranty

The length of the warranty is also an important consideration. Some companies may pay for replacement batteries in the event of a total failure.

However, if your battery capacity drops below a certain threshold while still under warranty, companies like Tesla and Volkswagen will still provide assistance.

The US federal government mandates an 8-year minimum guarantee for electric vehicle batteries.

You don’t want to spend more money than you have to on battery maintenance. Avoid spending money on the following activities.

  • Using non-standard pricing methods
  • Failure to make necessary repairs
  • Damage caused by unprofessional technicians during repairs
  • Lifting your electric vehicle beneath the battery
  • Opening the battery coolant incorrectly
  • Incorrectly deploying software or firmware updates

4. Battery Replacement

What should you do if you need to replace your battery because it has been damaged? In an effort to combat this problem, many automakers are working to increase the battery life of electric vehicles.

Tesla is working on an all-electric vehicle that will go a million miles before wearing out.

However, this does not apply to previously produced versions of electric vehicles. The service center will fix it for free if the damage happens during the warranty term. A new one should be purchased if the problem cannot be fixed and is not covered under warranty.

Changing the battery in your electric vehicle is like turning the key for the first time. The old battery can provide as emergency power for the local power grid.
