Does Electric Vehicle Range Really Drop by Half in Winter?

[KhloeLee]

Electric vehicles experience a significant reduction in range during winter. Rapid decline in energy release: Data shows that when the temperature drops from 25°C to -20°C, the battery's discharge capacity decreases by approximately 40%. Increased resistance: In low temperatures, the electrolyte ions inside the battery tend to move more slowly, increasing the battery's internal resistance and accelerating power consumption. This is one of the reasons for reduced EV range in winter. Other factors: At extremely low temperatures, to protect the battery, electric vehicles may disable energy recovery systems. If the cabin heating is also used under these conditions, the driving range will naturally decrease further.
