Aug 14, 2020   Pageview:89

Are you wondering which battery is ideal for an electric car  Or how long do electric car batteries last  If you have all of such queries, you are in the right article to answer all your questions.

Let’s get dive straight into your concerns and learn all you need to know about electric car batteries-

Which battery is best for an electric car

Depending on the specification and needs, how you want to use your electric car, there are two different battery types: lithium-ion or lead-acid. Each type of technology has its pros and cons, but choosing the one most suitable is crucial to choose the appropriate battery for your particular use.  Generally, batteries have Energy storage systems, which are essential for hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs).

Let's look at the basic characteristics of these two different batteries.

1). Lithium-ion batteries

Lithium-ion batteries, which have high capacity per unit mass compared to other electrical energy storage devices, are commonly used in most portable consumer electronics such as cellular phones and laptops. They also have a high power to weight ratio, best energy efficiency, good high temperature, and less self-discharge. While the exact chemical structure also differs from the battery used in consumer electronics, most of today's PHEVs and EVs use lithium-ion batteries. R&D aims to reduce costs and prolong their useful lives.

Reasons to choose lithium-ion batteries for electric cars:

Excellent autonomy- The autonomy of an electric car is almost doubled with this kind of battery.

Long lifespan- These batteries have about 2000 cycles; Such batteries last longer than the other types.

Quick recharging- They can be 100% recharged in 1.5h hours (80% in 1 hour), and partial recharging is also possible. Hence, they're ideal when the vehicle is used 24 hours a day.

Increased load capacity- They're much lighter than the other comparable batteries that use different technology types, so the vehicle has a higher effective ability.


2). Lead-Acid Batteries

Batteries with lead-acid are designed to deliver more power and are economical, safe, and reliable. Advanced lead-acid batteries are being produced. Those batteries are only used for auxiliary loads in commercially available electric drive vehicles.

Reasons to choose lead-acid batteries for electric cars:

Limited cost- The lead-acid is the least costly of all the different types of batteries. This type of battery is mainly applied when the vehicle speed is not a priority in the professional sense.

Versatile- Batteries of lead-acid can be used in various industries and with different vehicle applications because they require no specific attention. For example, they are ideal in campsites, electric vehicles, and general applications.

Long lifespan- It offers a charge duration of 1200 cycles, so its average lifespan is very high in context to its price.

How long does the battery last in an electric car

Keeping the battery in good condition for your electric car could extend your life; here's everything you need to know.

EV batteries experience 'discharge' cycles that occur while driving, and 'charge' cycles while plugged into the battery. Repeating this cycle over time determines how much power the battery will hold. It reduces the time and range taken to charge between each trip. Most battery manufacturers offer a five to eight-year warranty.

The electric car battery is a proven technology that will last for many years. Indeed, it is assured by the EV manufacturers. For example, Nissan guarantees its electric batteries for 8 years or 100,000 miles, and Tesla offers a similar guarantee.

EV manufacturers, therefore, go to great lengths to make batteries for electric cars last longer. Batteries are 'buffered' in an EV, meaning drivers cannot use the maximum amount of power they store, reducing the number of cycles in which the battery goes through. Together with other techniques such as smart cooling systems, means that batteries for electric cars will provide trouble-free life for several years.

Also, to maintain an electric vehicle battery's life, manufacturers ensure that sufficient spare capacity is available overtime to compensate for the degradation. Therefore the remaining spare capacity is used up as electric vehicle ages and the battery cycles. It allows the vehicle's range to remain the same over the battery life. When the battery capacity drops below 80%, drivers may begin to experience a drop in the battery's range and performance.

How much does it cost to replace an electric car battery

When it comes to replacing an electric car battery, you don't need to overthink because many suppliers have up to 8 years or 100,000 miles of warranty. In other words, if you need to replace it in an unfortunate case that something went wrong, it will be well covered under this agreement. Always check the form of warranty offered by your chosen electric car manufacturer.

The batteries' cost fell about 80 percent, which means from $1000 to $227 / kWh. Therefore, a modern 40kWh battery will cost only $ 10,000 short. Several forecasts suggest that by 2030 costs are likely to plunge below $100 / kWh, approximately around the same time.

Electric Car Battery Leasing

There's always a concern of any modern technology that things won't work as they planned. But several makers of hybrid vehicles and leasing firms have a way to inform consumers with the reassurance of the batteries. Many manufacturing companies provide a financing plan that encourages consumers to lease the battery, reduce the overall buying price, and guarantee battery output up to 75 percent of the original power.

That’s it. We hope that this guide has enlightened you enough on electric car batteries.
