“…Guo et al [55] Based on the design of an alternating current in the trapezoid heating method, to solve the problem is not suitable for trapezoid heating method in parameter Settings easy to endanger the battery health problem because of the adverse event, created a three-electrode cell is used to study trapezoidal heating in low temperature can affect the health of the battery, the experimental results show that the research of heating methods on the battery does not affect health. Shang et al [56] studied a high-frequency AC heater based on buck-boost transformation and developed an electrical model of a high-frequency thermal control heater based on ohmic resistance heating and lithium-ion transport. Experiment by studying the high-frequency AC heating topology and the effectiveness of the thermal model of different root mean square (RMS) current AC heating frequency, the results showed that the electrical flow in the same RMS AC frequency can significantly improve the heat rate and thermal efficiency, thus shows the ohmic resistance and lithium-ion battery transfer heat will not cause the damage of the battery.…”

Lithium-ion batteries (LIBs) require to be preheated under cold weather to restore performance, while DC pulse discharging is often considered a promising approach. Applying a larger pulse current can shorten the heating time, but it may lead to battery decay and demand additional cost. To keep the current lower in preheating, it is necessary to explore the effects of pulse current on the cell temperature rise and make full use of the battery’s heat-generating potential. This paper experimentally compared the effects of DC pulse, average (AVG) current, root mean square (RMS) current, pulse frequency, and state of charge (SOC) of the LIBs on its temperature rise rate, respectively. It is found that within the frequency of 1 kHz~10 kHz, the heat generation is affected by all factors above, among which the frequency has less impact while AVG current has the highest impact. During DC pulse discharging, it is shown that there is more entropy heat produced than the Joule heat in some SOC ranges. Therefore, entropy heat cannot be overlooked in the heat generation model. Moreover, as the thermal coefficient of entropy varies greatly with the SOC, the battery temperature rise rate will be inconsistent during the DC pulse discharging, which might cause an inconsistent warm-up time.

“…Comparing with cooling, heating LIBs was paid close attention in recent years. Despite all this, many effective heating methods have been presented, such as: alternating current (AC) heating method [18][19][20][21], liquid heating method [22,23], wide line metal film heating method [24][25][26][27] and self-heating LIB heating method (SHLBHM) [28,29], etc.…”

With the development of hybrid electric vehicles (HEVs) and electric vehicles (EVs), more and more attention has been paid to Li-ion batteries (LIBs). Since the charge-discharge performances of LIBs are affected by the temperature, an effective thermal management system is the key to solve the problem. Therefore, it is necessary to establish different simulation models to simulate the effects of the various thermal management systems. The prismatic pouch LIB cell is composed of multiple cell units connected in parallel, to reduce the calculation, the simplified models are used to simulate the LIB. In this paper, one detailed model and two simplified models are established to simulate temperature uniformity of heating LIB cells, and heating methods are the self-heating LIB structure heating method (SHLBHM) and the wide-line metal film heating method (WLMFHM). The simulation results of the detailed model and two simplified models are compared and analyzed. The results show that there are difference between the detailed model and two simplified models about temperature difference of the LIB cell, and the two simplified models have the same simulation results. Finally, the simulation results of the detailed models with different footprint areas are compared. The comparison results show that different footprint areas have no effect on the simulation results for both the self-heating LIB structure heating method and the wide-line metal film heating method.
