While internal combustion engines acquire their energy from burning gasoline or diesel, electric vehicles obtain their energy directly from a giant battery pack.
These are similar to a larger version of the lithium-ion (Li-ion) battery found in your smartphone; instead of a single battery, EVs employ a pack made up of thousands of discrete Li-ion cells that work together.

Electricity is utilized to make electrochemical reactions inside the electric car’s batteries while it is charging. These adjustments are reversed when it’s on the road to generate electricity.
Why do EV Batteries need to be replaced over time?
EV batteries go through a ‘discharge’ cycle when driving and a ‘charge’ cycle when the car is plugged in. The quantity of charge the battery can hold is affected by repeating this process over time.
This reduces the range and time required to charge between trips. The majority of battery manufacturers offer a five- to eight-year warranty on its battery pack. An electric car battery, on the other hand, is expected to last between 10 and 20 years before needing to be changed.
While it may be acceptable in a phone, it is insufficient for a car built to travel thousands of miles, thus EV manufacturers go to considerable pains to extend the life of electric car batteries.
Batteries in electric vehicles are ‘buffered,’ which means they can’t be used to their maximum capacity, lowering the number of cycles the battery goes through. This, combined with other measures like as smart cooling systems, implies that electric car batteries should last for many years.
Lithium-ion Battery Replacement Cost
You don’t have to be concerned about changing an electric vehicle battery because several manufacturers offer warranties of up to 8 years or 160,000 kilometers. This means that even if you needed to replace it in the terrible case that something went wrong, it might be covered under this warranty.
According to McKinsey Report, the cost of batteries dropped by nearly 80% between 2010 and 2016, from $1000 to $227/kWh.
As a result, in 2016, a new 40kWh battery would have cost slightly under £10,000. According to some estimates, prices will fall below $100 per kWh by 2030, around the same time as the government aims for more adoption of Electric Vehicles. In India, The cost of a Lithium-Ion Battery ranges from Rs.15000-20000 per kWh.
Let us take an example of the Tata Nexon EV- What is the battery replacement cost of Tata Nexon in India.
Note: The price of a 1kwh battery pack has gone up to 18,000-22,000 in India which is the approximate price- it may vary depending on the Indian state.
Tata Nexon EV Battery Replacement Cost in India?
Tata Nexon EV is by far the best range electric car in the Indian EV market, and it has a 31 kWh lithium-ion battery pack.
so, if we consider the price of 1 kWh lithium-ion battery pack is somewhere between 15,000 to 20,000 thousand, so The replacement price of the Tata Nexon EV Battery Pack will be around 5.50 Lakh to 6.20 Lakh in India
The replacement price of the Tata Nexon EV Battery Pack (31 kWh lithium-ion battery pack) will be around Rs 5.50 lakh to Rs 6.20 lakh in India.
The replacement price of the MG ZS EV Battery Pack (44.5 kWh 394 V lithium-ion) will be around Rs 6.60 lakh to Rs 8.50 lakh in India.
1. The li-ion batteries are meant for life time of up to 10 years.
2. Please let me know –
(a) how many charging cycles
(b) Fast charge current rating and numbers of permissible charge
(c) Will fast charge reduce life of batteries?
Answer to (A) In 4W Ev’s, The brand hasn’t shared any charging cycle limit for its battery yet. However, Its battery get 8-year/1.60 lakh km warranty. If we charge the battery pack once a day then 8 years = 2920 days. Typically it will have a life cycle of between 2000 – 3000 times.
Answer to (B & C): You can find the depth details in this article:
if replacement cost is 8 lacs, do you think its at par with CNG vehicle costs?
first, Electric vehicles have zero tailpipe emissions, which makes them even greener than CNG-powered vehicles.
second, Replacement cost is counted after 8 years of warranty period. So if your planning to even keep the CNG vehicle for 8 years, That engine life will reduce and 15% decrease in performance after in comparison to running on petrol.
Third, Price is based on today’s situation/market. Once demand will increase, Price will fall dramatically. So, Price for battery replacement after 8 years will be expected to be half than currant price.
All that calculation is good and luring. What and how to despise these batteries, even if battery companies are taking care, how do they as it leads to no use once utilised. Are we making earth as dump yard after the life of battery pack? Generally asking as a curious designer.
Reality is not as simplistic as textbook economics. We must be careful here.
Batteries require rare-earth metals. As the name suggests, they’re rare. Processing is resource-intensive and is responsible for large-scale excavations/mines – a dirty process, and expensive.
Also, these resources are available in very specific and limited regions, hence, are vulnerable to the volatile nature of geopolitical atmosphere.
