“…Currently, the low‐temperature thermal management of Li‐ion battery on the market is still achieved by using active preheating method, like air heating, liquid heating, and electrothermal element heating. [ 183 ] For example, Fan et al [ 184 ] numerically investigated the effects of heat plate on the temperature response of battery pack at −20 °C environment. They pointed out that the internally generated heat of batteries was negligible in comparison to the external heating source.…”

The performance of lithium‐ion batteries is quite dependent on temperature and a series of investigations on the battery thermal management system (BTMS) have been reported during the past decades. Herein, the recent developments of BTMS are thoroughly summarized. First, the thermal characteristics of the battery caused by different temperature conditions and temperature nonuniformity are described. Then, the thermal models, including electro‐thermal coupled model and electrochemical–thermal coupled model are briefly presented. Subsequently, various traditional strategies like air cooling, liquid cooling, phase change material (PCM) cooling, and heat pipe cooling are elaborated. With the development of battery technology, BTMS based on a single strategy alone cannot meet the growth of thermal requirements, especially under dynamic and high‐power energy conditions. Hence, a hybrid BTMS that integrates two or more cooling strategies begins to be studied and provide a feasible solution for the problem. The related studies on hybrid BTMS are also systematically reviewed from the perspective of combinations, such as air–PCM, liquid–PCM, heat pipe–PCM, and other hybrid strategies. Besides, the current research on battery preheating strategies is also summarized. Finally, insufficient present studies are pointed out, aiming to provide comprehensive guidance toward the development of battery thermal management.

“…Battery capacity is significantly lower for sub-zero operating temperatures [69]. In cold conditions, it is possible to partly heat the batteries with internally generated heat, but at temperatures as cold as −20 • C, internally generated heat is not enough to maintain the operating temperature at a sufficient level [70]. Temperature-related problems can, however, be overcome by installing auxiliary cooling and heating units.…”

“…The variation of battery out temperature with time for the integrated system with parallel circuit at various heater powers and flow ratios is presented in Figure 3a. The maximum battery heating temperature is cutoff at 40 • C because battery functions effectively below this temperature [8]. Therefore, the stopping criteria for the experiment at each flow rate and various heater powers is set as 40 • C, as shown in Figure 3a.…”

“…Fan et al concluded that the discharge rate has negligible effect on the heating performance of battery thermal management system compare with external heating source. In addition, a higher mass flow rate of the heating medium gives better heating performance [8]. Delos Reyes et al investigated the behavior in driving ranges of Mitsubishi i-MiEV and Nissan Leaf for the ambient temperature variation in a range of 20 to −15 • C [9].…”

The objective of the present study is to conduct experiments for investigating heating performances of integrated system with serial and parallel circuits for battery and heating ventilation and air conditioning system (HVAC) of electric vehicles under various operating conditions. In addition, the artificial neural network (ANN) model is proposed to accurately predict the heating performances of integrated system with serial and parallel circuits for battery and HVAC. A test bench of integrated system with serial and parallel circuits has been developed for establishing the trade-off between battery heating and HVAC heating. The heating performances namely, battery out temperature, battery temperature rise rate, battery heating capacity, HVAC heating capacity and total heating capacity are evaluated experimentally for the integrated system with serial and parallel circuits. The behavior of various heating performances is evaluated under influence of flow rate and heater power. Battery out temperature reaches 40 °C within 10 min with rise rate of 2.17 °C/min for the integrated system with serial circuit and that within 20 min with rise rate of 1.22 °C/min for the integrated system with parallel circuit. Integrated system with serial circuit shows higher HVAC heating capacity than integrated system with parallel circuit which are 5726.33 W and 3869.15 W, respectively. ANN model with back-propagation algorithm, Levenberg-Marquardt training variant, Tan-sigmoidal transfer function and 20 hidden neurons presents the accurate prediction of heating performances of the integrated system with serial and parallel circuits for battery and HVAC.
