Let me add some points.
I'm not an EV owner yet, but I have been following many threads for more than a year. Still, my petrolhead side doesn't allow me to switch to an EV.
Looking at your running of 100 km/day, you may need to charge the battery once every 3 days, assuming the range of the Creta Electric is around 380–400 km.
As we all know, NMC batteries have fewer charging cycles compared to LFP batteries — about 1,000–1,500 cycles, which is a medium lifespan when compared to LFP batteries like the BYD BE6 (2,500–3,500 cycles).
Creta Electric (NMC) will offer you more range and faster charging, but the battery life will be shorter — around 7–8 years with daily use.
If we consider your running, let's calculate how long your battery should sustain:
Charging once every 3 days makes about 10 times/month, which is 120 times/year.
That means in 10 years, you'll have about 1,200 charging cycles.
So it's clear that your battery lifespan would likely end around 10–12 years. Considering your average running of 36000/year, your Battery warranty (1,60,000km/8year) will get over by 5years itself.
Meanwhile, the main catch with LFP batteries is that even though they have 2,500–3,000 charging cycles, for the same kWh battery (like 51 kWh in the Creta Electric), you would need to charge more frequently because LFP batteries are heavier and offer slightly lower range for the same size.
To run 100 km/day with an LFP battery, you might have to charge every alternate day:
Around 15 times/month, making it about 180 times/year.
Over 10 years of ownership, you would end up charging approximately 1,800 times.
So technically, you could still have another 5 years of life left in the LFP battery after 10 years.
What I have observed over all these days is that even the 51 kWh Creta Electric might outperform the 61 kWh Atto 3 and even the 59 kWh BYD BE6 in terms of real-world range.
These are all my observations. Please correct me if I am wrong.
