“…The larger the amplitude of the temperature field is (the discharge rate is larger), the more heat the battery pack generates and the worse heat dissipation performance will be. X. M. Xu et al have analyzed the effect of angle cosine between velocity field and temperature field by field synergy principle; then the research in this paper compensates for the influence of the amplitude of the velocity field and the temperature field.…”

“…Figure shows the 55Ah battery cell temperature measurement point layout and thermal insulation design, including 2 measuring points on the bottom and 3 measuring points on the sidewall. Heat insulation box has 3 layers of insulating material surround, to ensure good thermal insulation performance . The heat insulation box wall includes 3 kinds of materials: the first material is a steel plate that reinforces the box structure, the second material is a foam rubber that thermally insulates the inside of the box from the outside, and the third material is aluminum foil that prevents radiation.…”

“… 5 This is because that the battery temperature will keep rising with the space constraint and time accumulation during charging and discharging processes. 6 8 When it exceeds the safety temperature range (−20 to 60 °C), 9 thermal runaway maybe caused and the consequence is fire accident. Actually, although the acceptable operating temperature range for Li-ion batteries is −20 to 60 °C, it is recommended to keep the temperature range within 15–35 °C to maintain optimal performance.…”

“…With the superior performance of high switching frequency, low conduction loss, and high over-current capacity, insulated gate bipolar transistor (IGBT) modules are widely employed in safety-critical power drive systems like electric vehicles (EVs) [1]- [3], aircraft [4], wind turbines [5] and industrial power drives [6]. However, owing to the variable power load and control input, IGBT modules are subjected to additional stresses, which may lead to different extent of thermo-mechanical fatigue/failure and further deterioration in the electric properties, increasing leakage currents and decreasing safe operation areas.…”
