Introduction
Electric cars are swiftly replacing other car types as the norm. We have the ideal opportunity to discuss the most contentious issue surrounding EVs: the battery.
Since every automaker is quickly turning its attention towards greener mobility, it is clear that the EV revolution is here to stay.
Granted, the range that batteries offer is contentious, but the batteries themselves are not! The most significant obstacle to purchasing an EV is ‘range anxiety.’ In an electric vehicle (EV), batteries are the energy storage device.
Now, let’s explore the types of batteries used in electric vehicles (EVs).
Different types of batteries used in electric vehicles
Alt: Exploring the Array of Batteries in Electric Vehicles
Embarking on the journey of electric vehicles (EVs) unveils a fascinating realm of technology, particularly in energy storage. Understanding the landscape of different types of batteries used in electric vehicles is essential for delving into the heart of this innovative automotive revolution. In this exploration, we delve into the diverse world of electric vehicle batteries, shedding light on the key players shaping the future of clean and efficient transportation.
-
Lithium-Ion Battery (Li-ion)
Li-ion batteries are the ones found in electric vehicles the most frequently. This provides:
- Exceptional energy economy.
- Good high-temperature performance (battery heat won’t affect performance).
- Strong capacity to be recycled.
- A superior power-to-weight ratio allows for a large charge-holding capacity even at reduced sizes.
- Minimal self-discharge (excellent at retaining charge even when inactive for extended periods).
The success of Li-ion as the preferred battery when creating EVs is mainly due to these characteristics.
-
Hybrid Nickel-Metal (NiMH) Batteries
Hybrid-electric vehicles (HEVs) more frequently utilise nickel-metal hydride (NiMH) batteries, offering longer life cycles and excellent safety than lead-acid batteries.
They also offer a stronger resistance to unfavourable conditions. However, there are serious issues with NiMH batteries because of their high rate of self-discharge and propensity to overheat. Their production costs are also higher.
Hybrid vehicles are the only option because scaling up to fully fledged electric vehicles (EVs) with NiMH batteries is much less practical due to these issues.
-
Solid State Batteries
Except for using solid electrolytes rather than liquid electrolyte solutions, solid-state batteries (SSB) are essentially lithium-ion batteries.
Therefore, the chance of catching fire decreases. To top it off, they last longer and have a higher energy density than lithium-ion batteries, making them ideal for electric vehicles. Still in its experimental stages, though, is the technology.
-
Lead-Acid Batteries
The earliest rechargeable batteries are lead-acid ones. Before lithium-ion batteries were discovered, these were the most practical choice. Though they typically weigh more and discharge more quickly, their manufacturing costs are substantially lower.
-
Aluminium-Ion Battery(AI-Ion)
Ion batteries made of aluminium are being extensively researched, particularly in India, despite not being widely used.
An enormous advantage of using Al-Ion batteries in the country’s massive bauxite (aluminium ore) reserves is that India is the world’s second-largest aluminium smelter. This would help the country produce more electric vehicles.
-
Ultracapacitors
Supercapacitors, or ultra-capacitors, are this list’s most unique energy storage units. Unlike regular batteries, supercaps store polarised liquid between the electrolyte and the electrode instead of traditional batteries.
As an alternative to NiMH batteries for secondary storage in electric vehicles, ultra-capacitors are highly suitable even though they are not as large as full-scale battery packs.
This is due to supercapacitors’ enormously high power delivery, which is fantastic following those crucial regenerative breaking start-stop acceleration moments.
Conclusion
Car insurance companies are adjusting to the new environment as electric vehicles become more commonplace on the roads. Comparing the insurance of an electric vehicle to that of a traditional vehicle may require some adjustments.
It is critical to comprehend the various battery types as the automotive industry continues to embrace electric vehicles.
Each battery technology has a unique set of benefits and drawbacks concerning driving range, charging time and overall performance.
