The idea of switching to electric cars (EVs) for a greener future sounds fantastic on paper, but owning an EV comes with several difficulties, including a limited operational range, and expensive battery replacement. Discussions will turn to the creation of infrastructure, like charging stations, and the adoption of battery swapping or the battery-as-a-service (BaaS) model as the globe starts to adopt EVs. So what is the need for a spare battery for Electric Cars?
A battery for an electric vehicle is an energy accumulator that stores electricity for delivery to an engine using either alternating or continuous current. Its significance is, however, much greater than this. These vehicles are sustainable because of the battery, which frees them from reliance on fossil fuels.
Lithium-ion, nickel-metal hydride, lead-acid, and ultracapacitors are electric vehicles’ four primary battery types.
What Does Battery-As-A-Service Or Battery Change Entail?
Electronic vehicle development is fuelled by growing fuel expenses, increasing pollution levels, and climate change concerns. Yet everyone is also worried about their exorbitant price, which is a major problem.
Hence, the battery-as-a-service business model was developed to address this issue. Up to 50% of the expense of an electric car is the cost of the battery. Customers can save money at the time of purchase thanks to the battery-as-a-service approach.
Consumers have two payment options: during each battery swap or through subscription programs. The government also announced the sale of electric two-wheelers and three-wheelers without a factory-installed battery in August of last year.
As a result of the lack of space for installing charging stations, the Union Finance Minister stated in her Budget Speech this year that the government will implement a battery-swapping policy to encourage the adoption of electric vehicles in the nation.
The private sector will be encouraged to develop sustainable and creative business models for ‘battery-as-a-service’ to improve efficiency in the Electric Vehicle ecosystem.
Using swap stations, EV owners may swap out their worn-out battery blocks with fully charged, ready-to-use ones.
Electric two-wheelers, three-wheelers, electric automobiles, and even e-buses are among the areas for which the technology is now being evaluated.
Stations for changing batteries might be manual or automated. Batteries are manually inserted into and taken out of the station’s slots when it has a manual station. The stations only take up a little room.
Why Are These Batteries Being Used?
Stations for changing batteries might be manual or automated. Batteries are manually inserted into and taken out of the station’s individual slots when it has a manual station. The stations only take up a little room.
Due to the reduced battery pack sizes and one person’s ability to handle them, these are primarily utilized for two- and three-wheelers. So why are these batteries become utilized?
Since the four-wheeler battery packs are heavier, automated stations with robotic arms are used. Any EV buyer’s second concern is range anxiety or the fear that the battery will discharge before reaching a charging station.
Moreover, consider how long it takes to charge them. Switching solves both issues. Since it is simpler to establish a dense network of swapping stations even in metropolitan areas, battery swapping is intended to minimize range anxiety.
Also, when EVs become commonplace, Indian towns will not have the physical space to accommodate hundreds of automobiles.

The Need For New Batteries Is Inevitable
The battery in an EV will eventually need to be changed, much as the battery in a gas vehicle. While there are things you can do to increase battery life, it will not last indefinitely. An EV battery may often be used for ten years before replacement is even a thought. Hence, you shouldn’t worry about changing the battery anytime soon if you purchase an EV today.
Battery switching has evolved into something akin to hydrogen fuel cells for cars: These are concepts for automobiles that are almost born but never quite do.
Exhibit A in the argument against the viability of battery switching is the turbulent history of the technology that can be traced to Better Place.
The world would be changed by robotic service stations that would remove a car’s battery and replace it with a new one, expanding its range in minutes, according to the Israel-based Better Place, created in 2007 by slick-talking Silicon Valley tycoon Shai Agassi. Battery changing appeared to offer misty promise in those quaint EV days when Tesla made modest steps with the Roadster (made from 2008 to 2011).
What About Tesla Battery?
Most cutting-edge EVs (including the 2011 Nissan Leaf and its 73-mile range) could only travel within cities except for Tesla.
As I recall from my own stressful journeys in San Francisco when I tried the original Leaf and BMW i3, dependable public charging hardly existed once the range was down. Batteries took an eternity to charge even when you did find a functioning socket.
Although the media hailed Agassi as the electric saviour and after receiving close to $900 million from investors, Better Place imploded like the Theano’s of its time. Robotic exchange stations cost $2 million instead of their intended $500,000 price tag.
Importantly, Agassi alienated such potential partners as BMW and GM, preventing Better Place from securing the support of any other automaker to develop and produce standardized vehicles with swappable batteries. Less than 1,500 electric Renaults were sold when Better Place was liquidated, and Agassi was sacked in disgrace in 2012.
Why Do People Use Spare Batteries?
Constructing extensive networks of swappable packs—which must be stored, kept charged, and maintained—would waste money and resources while also increasing carbon footprints because batteries are so expensive, large, and resource-intensive.
There would be a lot of extra batteries hanging around for buyers. Customers would eventually pay these excessive prices. Swap supporters have started to promote the prospect of stored batteries supplying power back to the grid after realizing the problem.
A switching infrastructure is another nightmare to build and maintain. Connecting EVs to the existing grid is undoubtedly more intelligent than playing a battery and robotic assistance shell game.
According to demand, the swapping concept would require dirty vehicles to transport batteries between stations. Large-scale bike rentals with 1,500-pound battery packs that cost $10,000 or more instead.
The intricate equipment of the stations would need far more upkeep than a charger with almost no moving parts, especially when mixed with filthy automobiles and packs.
Why Is A Battery Change Necessary In An Emergency?
If those challenges seem overwhelming, we have yet to mention the worst ones: Vehicles and batteries are not standardized by automakers, and they have no intention of doing so. Some businesses cannot even agree on a charging protocol, much fewer batteries that could be used with any car, SUV, or pickup. Without standardization, each automaker would have to create its own exclusive.
Yet, unlike what supporters of battery swaps would have you believe, autos are nothing like cordless drills. Each automaker’s battery design is intricately linked to its distinctive vehicle designs, which support many automobile models.
Batteries are enabling different module counts and orientations to maximize energy storage, even within a single automaker, as seen with GM’s new Ultium packs. Modern packs are created as interconnected, weight-bearing structural parts to withstand rigorous crash testing. None of them are made to be universally applicable or simple to remove and reinstall.
Electric Car Battery Types
| Lithium-ion batteries | The lithium-ion battery is the most typical battery type used in electric vehicles. This type of battery might seem familiar to you because it is used in most portable electronics, including laptops and cell phones. |
| Nickel-metal hydride batteries | Although they are more frequently seen in hybrid-electric vehicles, nickel-metal hydride batteries can also be found in select all-electric vehicles. Hybrid-electric vehicles are not considered to be electric cars because they use fuel to recharge their batteries rather than an external plug-in source of electricity. |
| Lead-acid batteries | Nowadays, lead-acid batteries are only utilised in electric vehicles as a backup for other battery loads. |
| Ultracapacitors | In the conventional sense, batteries are not what ultracapacitors are. They keep polarised liquid instead, sandwiched between an electrode and an electrolyte. The liquid’s ability to store energy rises along with its surface area. |
- Batterie Lithium-Ion
Lithium-ion batteries provide good energy efficiency, a high power-to-weight ratio, and exceptional high-temperature performance. In real terms, this means that the batteries have a high energy-to-weight ratio, which is crucial for electric automobiles because lighter vehicles can travel farther with a single charge. Lithium-ion batteries are also superior to conventional batteries at maintaining their capacity to hold a full charge over time because they have a low “self-discharge” rate.
- Batteries With Nickel-Metal Hydrides
Batteries made of nickel metal hydride have a longer lifespan than lithium-ion or lead-acid batteries. Nevertheless, they are secure and accepting of abuse. The main problems with nickel-metal hydride batteries are:
- Their high price.
- Rapid self-discharge rate.
- They do, in fact, generate a significant amount of heat at high temperatures.
- Owing to these issues, hybrid electric vehicles often use these batteries rather than rechargeable ones.
- Lithium-Ion Batteries
These batteries are strong, inexpensive, safe, and trustworthy, but because of their short calendar lives and poor cold-temperature performance, they are difficult to use in electric vehicles. High-power lead-acid batteries are being developed, however, they are currently only used in commercial vehicles as secondary storage.
- Ultracapacitors
Ultracapacitors, like lead-acid batteries, work best as secondary storage elements in electric cars because they assist electrochemical batteries in balancing their load. Moreover, ultracapacitors can give electric vehicles more power when accelerating and using regenerative braking.
What Are The Advantages Of A Spare Battery?
Battery swaps are ultimately doomed by capitalism itself and competition. Every major automaker would have to scrap their current and future product plans and start from scratch to produce common vehicles and battery packs. And what benefit?
Automakers do, in fact, occasionally collaborate to share technology, as when Yamaha and Ultium batteries developed two models together. Yet, consider if Tesla or General Motors agreed to practically give away their most valuable intellectual property on the market today:
The battery chemistries, electronic controllers, and designs, as well as the EVs they power. These fundamental competencies include giga-scaled lithium-ion cell manufacturing that needs billions of dollars in investment.
Conclusion
Most automobiles on the road now worldwide are fuel-powered. But, as consumers become more aware of the environmental harm being done, which has a negative impact on our health, they are constantly looking for climate-friendly transportation options. Hence, there is now a greater than ever need for EVs.
FAQs
What happens when an EV battery needs to be replaced?
EV batteries will gradually lose capacity over time; modern EVs’ average annual range loss is about 2%. With time, the driving range could dramatically shrink. EV batteries can be kept in good condition, and if any of the battery’s cells break down, they may be replaced.
How long can a spare automobile battery be kept?
Most manufacturers advise keeping batteries in storage for six to nine months before use, and postponing use won’t increase the battery’s three to five-year lifespan.
What purpose does a battery serve in an electric vehicle?
A battery for an electric vehicle is an energy accumulator that stores electricity for delivery to an engine using alternating or continuous current. Its significance is, however, much greater than this. These vehicles are sustainable because of the battery, which frees them from reliance on fossil fuels.
How long until they need to be recharged electric car batteries?
Electric vehicle batteries generally last ten to twenty years. But other factors might make that period shorter. Batteries, for instance, may degrade more quickly in hotter climates since heat does not play well with EVs.
How much does it cost to replace an EV battery?
According to experts, replacing the electric vehicle battery generally costs between $2,000 and $10,000. However, some are more expensive. According to the International Energy Agency, sales of electric vehicles will double to 6.6 million in 2021, setting a record.
