Temperature plays a major role in battery performance, charging, shelf life and voltage control. Extreme conditions, in particular, can significantly affect how a battery performs. What is the relationship between battery capacity and temperature? The performance of a battery is tied to the ambient temperature in which it operates.
The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
For optimal performance, lithium-ion batteries should operate within the temperature range of 20°C–55°C . Operating lithium-ion batteries outside this temperature range poses security risks and can cause irreversible damage to the battery.
For cylindrical cells with a small radius (e.g., 18650 cell), the Biot number is usually less than 0.1 under natural convection cooling conditions (e.g., h < 25 W / m 2 K) and the temperature difference between the battery core and the surface can be less than 5 °C even at high operating rates, as presented in Fig. 3 (b) [, , , ].
The thermal properties of the cell are also dependent on the SOC, temperature, and aging status , causing different thermal responses. For battery cells with different chemistries and formats, the heat transfer patterns differ remarkably and therefore yield distinct temperature distributions.
There is a general belief that the battery pack should not have a temperature difference exceeding 5 °C . Figure 6. (a) Schematic diagram of the experimental setup, and (b) comparison cycle life performance . 3. Air Cooling Technology Battery packs are normally cooled with air cooling technology.
