Lithium-Ion Battery Pack
The primary energy storage component in electric and hybrid vehicles.
Lithium-ion batteries power electric motors with high energy density and lightweight construction. Each pack contains numerous cells grouped into modules. The pack includes cooling systems and protective casings to manage heat. Charging cycles affect long-term capacity, so controlled thermal management is essential. Recycling and second-life use of these batteries help reduce environmental impact. Modern EVs use advanced chemistries like NMC or LFP for improved safety and cost efficiency.
