Abstract:In this paper, techniques to improve cooling and temperature uniformity in a simple battery pack are examined. Four battery pack configurations are developed. In the first configuration, an inlet plenum is added to a simple battery pack. In the second configuration, jet inlets are incorporated along with the inlet plenum, and in the third configuration, multiple vortex generators are added in addition to the inlet plenum. Finally, in the fourth configuration, an inlet plenum, jet inlets, and multiple vortex generators are incorporated into the battery pack. The results conclude that by adding inlet plenum, multiple vortex generators, and jet inlets in the same configuration, significant improvements are observed. The results also show that the maximum temperature of the battery pack is reduced by~5%, and the temperature difference between the maximum temperature and the minimum temperature exhibited by the battery pack is reduced by 21.5%. Moreover, there is a~16% improvement in the temperature uniformity of a single cell.

“…Also, the ΔT must be maintained below 5°C by means of effective thermal management systems [13,14] .Therefore, selecting an appropriate heat dissipation system is of critical importance for power battery modules [15,16]. At present, traditional air cooling [17][18][19] cannot transfer the heat generated from batteries quickly with the increasing module capacity and specifications. Although the liquid cooling [20,21] method has a better heat dissipation effect, some disadvantages include complicated system, difficult maintenance, and high cost.…”

The temperature has to be controlled adequately to maintain the electric vehicles (EVs) within a safety range. Using paraffin as the heat dissipation source to control the temperature rise is developed. And the expanded graphite (EG) is applied to improve the thermal conductivity. In this study, the paraffin and EG composite phase change material (PCM) was prepared and characterized. And then, the composite PCM have been applied in the 42110 LiFePO 4 battery module (48 V/10 Ah) for experimental research. Different discharge rate and pulse experiments were carried out at various working conditions, including room temperature (25°C), high temperature (35°C), and low temperature (−20°C). Furthermore, in order to obtain the practical loading test data, a battery pack with the similar specifications by 2S * 2P with PCM-based modules were installed in the EVs for various practical road experiments including the flat ground, 5°, 10°, and 20°slope. Testing results indicated that the PCM cooling system can control the peak temperature under 42°C and balance the maximum temperature difference within 5°C. Even in extreme high-discharge pulse current process, peak temperature can be controlled within 50°C. The aforementioned results exhibit that PCM cooling in battery thermal management has promising advantages over traditional air cooling.

“…The air conditioning method has advantages such as simple operation and a small cost, while the temperature regulating efficiency is low. Once the discharge current exceeds 30 A, the air cooling will not reach the heat dissipation requirement of the battery [15]. Therefore, the medium of the thermostat system is changed to improve the efficiency of the temperature adjustment.…”

“…Huo et al [17] reviewed the research progress on the application of liquid medium to the thermal management of the battery, and pointed out that although the liquid temperature regulating efficiency is high, it needs a more complex structure and higher quality and is complicated to install. Lin et al [15] studied phase change materials for the thermal management of batteries and found a better ratio of paraffin wax. Ramandi et al [18] studied heat transfer in and thermal management of electric vehicle batteries with phase change materials.…”

Abstract:As is known to all, a battery pack is significantly important for electric vehicles. However, its performance is easily affected by temperature. In order to address this problem, an enhanced battery thermal management system is proposed, which includes two parts: a modified cooling structure and a control unit. In this paper, more attention has been paid to the structure part. According to the heat generation mechanism of a battery and a thermoelectric chip, a simplified heat generation model for a single cell and a special cooling model were created in ANSYS 17.0. The effects of inlet velocity on the performance of different heat exchanger structures were studied. The results show that the U loop structure is more reasonable and the flow field distribution is the most uniform at the inlet velocity of 1.0 m/s. Then, on the basis of the above heat exchanger and the liquid flow velocity, the cooling effect of the improved battery temperature adjustment structure and the traditional liquid temperature regulating structure were analyzed. It can be seen that the liquid cooling structure combined with thermoelectric cooling demonstrates a better performance. With respect to the control system, the corresponding hardware and software were also developed. In general, the design process for this enhanced battery thermal management system can provide a wealth of guidelines for solving similar problems. The H commutation circuit, matrix switch circuit, temperature measurement circuit, and wireless communication modules were designed in the control system and the temperature control strategy was also developed.
