Learn MoreThey obtained that the battery maximum temperature increases with heat generation and with the decrease of Reynolds number and conductivity ratio. They found that thermal oils, nanofluids and liquid metals provide the same maximum temperature range.
This increase in temperature within the battery cell is due to the interplay of thermal effects within the cell. The heat generated in one cell affects adjacent cells, and this thermal coupling extends to the entire module, propagating heat throughout the battery pack.
However, due to high current loading conditions such as fast charging or accelerations, the transient battery can experience unacceptable temperature rise. Lithium-ion batteries are usually arranged in the battery pack by series-parallel configuration.
Heat generation inside the battery happens due to the exothermic reactions as well as the ohmic loss in the solid and electrolyte phases due to charge transport resulting in temperature rise in the cell. The heating of the cells affect neighboring cells via thermal coupling in the module.
There is also the thermal effect on battery degradation. It has been noticed that the battery works more reliable at room temperature. Because they are designed like that, they can work at room temperature. At low temperature, the internal resistance of the battery increases and thus reduces the capacity.
Inversely, the electrochemical reaction becomes exothermic during discharging state leading to an increase in the battery temperature. The battery temperature level depends on the migration rate of Li + ions through the electrolytic solution between the positive and negative electrodes of the battery.
