High temperatures (above 60°C or 140°F) can speed up battery aging and pose safety risks. Extreme temperatures shorten battery lifespan and reduce efficiency. Controlled environments and thermal management systems help maintain safe battery temperatures.
The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .
The standard rating for batteries is at room temperature (25°C/77°F). At approximately -22°F (-27°C), battery capacity drops by 50%. At freezing capacity, it is reduced by 20%. Capacity is increased at higher temperatures. At 122°F, a battery's capacity will be increased by about 10-15%.
A sub-optimally designed battery pack reaches higher temperature fast and does not maintain temperature homogeneity. According to the best design practices in the EV industry, the temperature range should be kept below 6 degrees for a vehicle to perform efficiently. Fig 1. Cell Temperature for Case I
Capacity is increased at higher temperatures. At 122°F, a battery's capacity will be increased by about 10-15%. As mentioned earlier, battery charging voltage also changes with temperature. It will vary from about 2.74 volts per cell at -40°C to 2.3 volts per cell at 50°C. This is why temperature sensing and compensating chargers are so important.
It is noteworthy that high temperature will affect the viscoelastic behaviors and mechanical strength of polymer, which may further trigger the structural failure of the batteries . 2.1.3. Thermal runaway
