Two EVs with the same battery chemistry can deliver wildly different range, charge speed, and longevity, and almost all of the difference lives in the thermal-management system. We walk why lithium cells have a narrow happy band, liquid versus air cooling, preconditioning and why it matters at fast chargers, the cabin heat pump that recycles waste heat, and the failure modes the marketing does not advertise.
