Why EV Range Drops in Summer & Winter: Causes & Proven Solutions

⚡ VoltSens Verified Automotive Research & Analysis

Lithium-ion batteries operate with maximum chemical efficiency within a sweet spot of 20°C to 30°C. In North India where temperatures swing from 3°C in January to 48°C in June, thermal management systems consume extra energy to protect the cells.

The Summer Range Penalty (40°C+)

In summer, the vehicle's air conditioner and battery active cooling pumps run at maximum speed. Running the cabin AC at 18°C on full blower consumes 1.5 kW to 2.5 kW of continuous electrical power, reducing driving range by 15% to 22%.
