EV battery price statistics
- $108/kWh average lithium-ion battery pack price in 2025, down 8% year over year. (BloombergNEF, 2025)
- $99/kWh BEV pack price — the second year below the $100/kWh threshold. (BloombergNEF, 2025)
- $81/kWh average LFP pack price, vs $128/kWh for NMC packs. (BloombergNEF, 2025)
- $84/kWh China's average pack price, down 13%; North America and Europe run 44–56% higher. (BloombergNEF, 2025)
EV battery degradation & lifespan statistics
- 2.3% per year average battery degradation across 22,700+ real-world EVs. (Geotab, 2025–2026)
- 81.6% projected average state of health at the 8-year mark. (Geotab, 2025)
- +0.4%/yr faster degradation in hot climates — about 4% more loss over 10 years. (Geotab, 2025)
