Generally, at around minus 10 degrees Celsius, battery capacity can decrease by 20%, leading to a 20% reduction in range. Furthermore, when the temperature drops further to minus 20 degrees Celsius, battery capacity and range can decrease by 40% each. In simple terms, for example, an electric vehicle that could originally travel 500 kilometers on a full charge might only be able to cover around 300 kilometers in winter conditions at minus 20 degrees Celsius.
To increase the range of electric vehicles in cold winter conditions, it's important to focus on proper charging and discharging methods, as well as battery insulation. When purchasing an electric vehicle, it's advisable to consider the brand's insulation performance and choose a model with better insulation capabilities.
Additionally, during the charging process, placing the electric vehicle in a warm underground garage or in a sunny outdoor environment can help increase the battery's temperature. Moreover, maintaining a constant speed while driving in winter can significantly reduce energy consumption. Avoiding rapid acceleration from a standstill and frequent use of brakes can effectively lower the rate of energy consumption.
