Operating lithium-ion batteries at high temperatures significantly impacts their capacity and efficiency. Studies show that at 30°C (86°F), the cycle life of a battery decreases by 20%. Elevated temperatures also accelerate. . A typical lithium ion battery pack may lose 20-40% of its rated capacity when operating at freezing temperatures compared to room temperature performance. This capacity reduction stems from both kinetic limitations and thermodynamic effects that become more pronounced as temperatures decrease. Once they exceed this comfort zone, whether in freezing cold or extreme heat, degradation accelerates.
