|---|---|---|---|
| Tata Nexon EV | ₹14.79L | ~22% | ₹9-11L |
| Tata Tiago EV | ₹7.99L | ~25% | ₹5-6L |
| Ola S1 Pro | ₹1.35L | ~35% | ₹60-75K |
| MG ZS EV | ₹18.98L | ~20% | ₹12-14L |
| BYD Atto 3 | ₹24.99L | ~10% | ₹19-21L |
What is State of Health (SoH) for EV Batteries?
State of Health (SoH) is a percentage that reflects how much energy your EV battery can hold compared to when it was brand new out of the factory. For example, if a Tata Nexon EV had a 30 kWh battery initially, an SoH of 90% means it can now only store about 27 kWh. This directly translates to lower real-world range. Unlike a petrol car engine which can be serviced to regain efficiency, battery degradation is irreversible.
How Battery SoH Affects EV Resale Price in India
In the Indian used car market, battery SoH is the single biggest determinant of price. Since a replacement battery pack can cost up to 40% of the vehicle's initial ex-showroom price, buyers are wary of EVs with an SoH below 80%. An EV with 95% SoH might sell for ₹1-2 lakh more than the exact same model with 85% SoH. Our calculator factors in your charging behavior—like whether you frequently use DC fast chargers or charge to 100% daily—because these habits accelerate battery degradation.
