The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .
For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.
At higher temperatures (>+40 °C), the charging and discharging performance generally remain good as the internal resistance decreases further , but battery degradation and self-discharge may be faster due to higher chemical activity , , , . The HVAC load is also increased .
The increase in the charging time is considerable due to extreme temperatures, but using the charging time as a sole metric may not be adequate to describe the effects. This is because charging becomes less effective in terms of energy stored per unit time in the constant voltage phase of charging.
Heat generation within the batteries is another considerable factor at high temperatures. With the stimulation of elevated temperature, the exothermic reactions are triggered and generate more heat, leading to the further increase of temperature. Such uncontrolled heat generation will result in thermal runaway.
A low ambient temperature tends to increase the charging time of the fleet via an increased internal battery resistance, even by more than 100% at −10 °C if the batteries are not heated. The charging time at −10 °C can be reduced by around 28% if standby BTM and cabin preconditioning are enabled.
