Temperature measurement is important in preserving the operational characteristics of both the cells and the BMS itself, as well as optimizing the state of health (SOH) by preventing degradation, especially during the phases of fast charging and discharging.
(1) Stabilize the battery pack temperature to 45 °C; (2) The cold plate initiates operation, and the experiment concludes upon reaching a temperature of 25 °C for the high-temperature battery pack.

In high-power applications, the charge controller requires multiple temperature sensors mounted on the Li-Ion battery. At least one sensor monitors each cell of the battery. NTC thermistors are the sensor of choice to provide temperature feedback to the ADC.
The thermal regulator's monitoring and controlling of the batteries' temperature was accomplished through a passive and negative feedback mechanism. Although the latent heat brought the switching delay to some extent, the reliability was also ensured in this regulating mechanism.
At least one sensor monitors each cell of the battery. NTC thermistors are the sensor of choice to provide temperature feedback to the ADC. The charge controller monitors battery cell temperature individually or collectively depending on the controller type and number of cells in the battery.
Batteries are affected by temperature changes because temperature impacts the kinetic energy of the molecules found in battery materials (such as the electrolyte and the electrodes). This makes these materials more or less conductive based on their temperature.
Heat created by the chemical reaction of charging acts to increase the initial temperature of the battery. The optimum Li-Ion battery temperature range during charging is quite narrow, between 10°C and 30°C (41°F to 86°F). Fast charging, while acceptable, requires that battery temperature not exceed 45°C (113°F).
