EV
Battery thermal management
How the EV cools and heats its battery pack — liquid systems outlast passive air systems.
Liquid-cooled packs (Tesla, Kia EV6, Polestar 2) degrade more slowly than air-cooled packs (early Nissan Leaf). For a used EV in Sydney's climate, liquid management is essentially mandatory — air-cooled Leafs lose 20–30% capacity in 5 years here.
