Customer ServiceThis paper evaluates the use of temperature-life Arrhenius model and decade rule in accelerated temperature testing and modeling of batteries and provides a proper approach for life test planning and modeling. Battery manufacturers and device companies often test batteries at high temperature to accelerate the degradation process.
Customer ServiceThe temperature of the battery thermal management system changes in real time and can vary between −20 °C and 60 °C. The DP algorithm requires discrete state variables, and a relatively large range of temperature changes increases the number of grids, leading to an increase in computation time.
High voltage and increasing temperature will deteriorate the output performance of the existing battery thermal management system, and thus risk for loss of energy, damage to battery life, and low storage capacity is always there.
As the temperature increases within this range, the activity of the internal active materials is enhanced, and the charging/discharging voltage, efficiency, and capacity of the battery increase accordingly, resulting in a corresponding reduction in the internal resistance.
The experimental temperature is set at 40 °C. The common power battery testing environment requirements are between 0 and 40 °C. If the ambient temperature is lower than 0 °C or greater than 40 °C, the performance of the power battery will decrease, resulting in a corresponding decrease in discharge capacity.
Fig. 1 is a simplified illustration of a battery system's thermal behavior. The total heat output in a battery is from many different processes, including the intercalation and deintercalation of the existing ions (i.e., entropic heating), the heat of phase transition, overpotentials, and the heat discharge due to mixing.
The simulation results in heating mode under multiple driving cycles and environment temperatures are displayed in Table 4. The temperature at which the battery needs to be heated is mainly between −20 and 0 °C. Thus, the environment temperatures selected for the heating mode include −20, −10, and 0 °C.
