One can say for sure that the growing enthusiasm for the purchase of Electric Vehicles has increased demand for efficient batteries. Electric Vehicles have already become a popular replacement for vehicles with the conventional engine, thanks to EVs’ superiority over ICE vehicles.
The most significant advantages of Electric Vehicles include:
This article first takes a quick look at what a battery is, and then explores the types of batteries used in such vehicles. It also addresses the EV batteries’ parameters to be considered while buying an EV. The essay comes to an end with tips to extend EV batteries’ lifespan.
An Electric Vehicle battery is a rechargeable battery which is used to power the electric motors of an EV or Hybrid Electric Vehicle. In fact, it is an energy accumulator that stores electricity for transmission to an alternating or continuous current engine.
There are three types of rechargeable batteries that are suitable for Electric Car use. They are Lithium-ion (Li-ion) batteries, Nickel-metal hydride (NiMH) batteries, and Lead-acid batteries.
Lithium-ion batteries are the most frequently used batteries in Electric Vehicles. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect. The Li-Ion is 1/3 the weight compared to the lead-acid. It also has three times the cycle life and is three times more powerful. Li-Ion batteries come with an advantage with an energy rate of 140+ Wh/kg. As for their disadvantages, experts say Li-ion batteries’ biggest disadvantage is their high cost. Their production costs are known to be 40% higher than that of nickel batteries.
There are different types of lithium-ion batteries:
These kinds of batteries have superior specific energy to lead-acid ones. They hold a value of 68 Wh/kg and a range of 60 to 120 Wh/kg.
These batteries are proven well to use in EVs with a good mileage and long lifespan.
The lead–acid battery is the first type of rechargeable battery ever created and is still being used. Lead-acid batteries’ advantage is their affordable cost. However, there are significant disadvantages. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. This battery type comes with a short lifespan of 3 years. And, considering it is made from lead, this battery type is heavy.
If you want to get the most out of your Electric Vehicle, consider battery parameters mentioned below:
Life Span
The life cycle of a battery depends on different factors. But most EV batteries have a lifespan of approximately 10 years before a replacement is required.
Safety
The safety considerations in battery management for battery pack technologies are crucial to ensure that the overall electrical system is in accordance with high standards of safety, reliability, and quality. A carefully designed battery management system (BMS) assures safe operation.
Cost
When it comes to the cost of car batteries, Electric Vehicles win first place for the most expensive type.
Obviously, the great interest in buying Electric Vehicles worldwide, calls for better performance, reduced weight, better cycling ability, and better driving range of EV battery systems.
Now that you know more about different EV batteries, it’s time to learn how to maximize your battery life. There are simple ways to make your battery last longer.
1. Keep your battery at optimal battery charging levels during periods of inactivity
This will help avoid excessive wear on the battery.
2. Limit exposure to extremely high or low temperatures when parked
Parking indoors in cold and hot weather helps protect your battery.
3. Don't use fast charging regularly
If you use fast charging frequently, it will degrade your battery. Just use them when necessary.
4. Minimize the batteries at 100% state of charge
A full charge will definitely provide you with high operating time, but it is not suggested whatsoever.
5. Practice good driving habits
Some extreme driving habits can ruin the battery. For instance, rapid acceleration and deceleration will increase heat, and heat is bad for any battery.
Make sure you remember these tips, as a healthy battery brings more convenience and joy to EV owners.
