How Extreme Heat or Cold Affects Chinese EV Range

The main factors are battery chemistry (LFP vs. NMC), the efficiency of the thermal management system (heat pump vs. resistive heater), and whether the vehicle supports battery preconditioning. Cold weather slows chemical reactions and increases internal resistance, reducing usable capacity. Heat causes increased battery cooling demands and high AC load. Chinese EVs often use LFP batteries which are more sensitive to cold but cope well with heat, while NMC handles cold better. A heat pump can reduce heating energy consumption by up to 30% compared to a resistive heater, significantly preserving range.

Look for a heat pump as standard or optional—this is crucial for cold climates. Check if the vehicle has battery preconditioning (can be scheduled or activated via app) to warm the battery before driving. For hot climates, verify the AC system’s efficiency and whether the battery has active liquid cooling. Also, consider models with larger battery capacities as a buffer against range loss, and ask about real-world range tests in extreme conditions from local owners.

Buyers in regions with harsh winters (northern Europe, Canada, northern US) should prioritize models with heat pumps and preconditioning, and be prepared for significant range reduction. In hot climates (Middle East, southern US, Australia), the range loss from AC is less severe but still notable; battery cooling becomes key to prevent degradation. Urban drivers who charge daily may tolerate more range loss than long-distance commuters. Fleet buyers or those relying on public charging may need to adjust routes or charge more frequently in extreme weather.
