EV vs Battery Cost Split
EV (excl. Battery)Battery
Key Insight
35–45%
of total EV cost is attributed to the battery pack — making it the single most expensive component and the key driver for secondary-life economics.
2W Scooters have the highest battery cost ratio at 44%, while 4W Passenger EVs sit at 35%.
Section 02
Post-Warranty Economics
What happens after the warranty expires — depreciation, resale, and replacement economics
| EV Category | Warranty | Original Price | Resale Value | Battery Replacement Cost | Battery Resale Cost |
|---|---|---|---|---|---|
| 2W E-Bicycle | 2 yrs | ₹35,000 | ₹8,000 | ₹7,000 | ₹3,500 |
| 2W Scooter | 8 yrs | ₹1,25,000 | ₹32,000 | ₹42,000 | ₹20,000 |
| 3W Auto | 5 yrs | ₹2,85,000 | ₹85,000 | ₹1,00,000 | ₹45,000 |
| 4W Passenger | 8 yrs | ₹15,00,000 | ₹4,25,000 | ₹5,25,000 | ₹2,00,000 |
| EV Buses | 10 yrs | ₹1,85,00,000 | ₹40,00,000 | ₹60,00,000 | ₹20,00,000 |
| EV Trucks | 8 yrs | ₹45,00,000 | ₹12,50,000 | ₹15,00,000 | ₹6,00,000 |
⚠️
Critical Finding:In most segments, the cost of battery replacement exceeds the vehicle's post-warranty resale value — creating a strong economic case for secondary-life battery repurposing instead of disposal.
