Instead the electric vehicle should limit power to minimize further temperature increase and prevent degradation or worse, thermal runaway. The ideal battery temperature for maximizing lifespan and usable capacity is between 15 °C to 35 °C. However, the temperature where the battery can provide most energy is around 45 °C.
High temperatures increase the effective force of the electric current that drives lithium ions from one node of the battery to the other, causing physical stress and damage on the receiving end. The higher the temperature - or the higher the current - the more stress fractures and damage the battery node experiences.
The desired operating temperature of a lithium-ion battery in an electric car is 15 °C to 35 °C. Below 15 °C the electrochemistry is sluggish and the available power is limited. A significant and noticeable difference probably starts at temperatures below zero degrees.
On the other hand, a limited capability to recuperate at low temperatures serves to protect the battery from accelerated aging, which ultimately leads to less energy regeneration. This paper analyzes the impact of both factors separately on a battery electric vehicle’s driving range.
