How Much Does Electric Vehicle Range Decrease in Winter?

[KarterFitz]

Under normal circumstances, for every degree the temperature drops, the battery's capacity decreases by approximately 1%, leading to a corresponding reduction in range. The specific decrease in mileage can be calculated based on the data displayed on the vehicle's computer. Reasons for the decrease: The lower the temperature, the harder it is for the battery's electrolyte to diffuse, slowing down the chemical reaction rate of the active materials at both electrodes, which in turn causes the battery voltage to drop. Winter vehicle usage precautions: Vehicles should not be parked for extended periods in winter. When the battery discharges below 50%, the electrolyte may freeze, making it difficult to start the engine. It is advisable to start the vehicle intermittently, avoid excessive battery discharge, and try to maintain the battery charge at around 50%.
