“…In addition to the above studies, a heat pipe (HP) with high thermal conductivity in the longitudinal direction and isothermal properties in heat conductive direction, and a thermoelectric cooler (TEC) characterized by refrigeration ability, rapidly transferring heat, small size, and high reliability, were both investigated [16][17][18]. Joshua et al [19] applied the HP to BTMS, and found it can better control the temperature of the Li-ion battery than the traditional liquid cooling system. Deng et al [20] combined an L-style HP with an aluminum plate to build a BTMS and showed that with ambient temperature increasing, the heat dissipation from HP increases and the increasing rate of battery temperature reduces.…”

The temperature of electric vehicle batteries needs to be controlled through a thermal management system to ensure working performance, service life, and safety. In this paper, TAFEL-LAE895 100Ah ternary Li-ion batteries were used, and discharging experiments at different rates were conducted to study the surface temperature increasing characteristics of the battery. To dissipate heat, heat pipes with high thermal conductivity were used to accelerate dissipating heat on the surface of the battery. We found that the heat pipe was sufficient to keep the battery temperature within the desired range with a midlevel discharge rate. For further improvement, an additional thermoelectric cooler was needed for a high discharge rate. Simulations were completed with a battery management system based on a heat pipe and with a combined heat pipe and thermoelectric cooler, and the results were in line with the experimental results. The findings show that the combined system can effectively reduce the surface temperature of a battery within the full range of discharge rates expected in the battery used.

“…Actually, the thermal management for large-capacity battery has already been investigated in numerous studies. Compared with the small-capacity battery, Air 24 , liquid 21,[25][26][27][28] , heat pipe 29 , and phase change materials (PCM) [30][31][32] are still the main methods to cool the largecapacity battery at present. In these studies, the performance of the BTMS for large-capacity battery was shown in the experiments and simulation by considering many factors, such as C-rates 24,25,30,32 , cooling structures 21,32 , air or liquid flow rate 24,25 , ambient temperature 25 , and cycle duty 31 .…”

Summary A proper and effective battery thermal management system (BTMS) is critical for large‐capacity pouch cells to guarantee a suitable operating temperature and temperature difference. Hence, in this paper, a micro heat pipe array (MHPA) is utilized to build the thermal management system for large‐capacity pouch cells. In order to study the property of BTMS in depth, experimental and numerical investigation are carried out by considering the C‐rate, working medium, air velocity and duty. The experimental results present that the Tmax can be maintained below 43.7°C and the ΔT is below 4.9°C at the discharge rate of 3C in the battery module with MHPA‐liquid. Moreover, the Tmax of the battery module with MHPA‐liquid falls as the air velocity increases. The simulation results show that the variation and distribution of temperature matched well with experimental results. It demonstrates that the MHPA‐based BTMS is viable and effective for large‐capacity pouch cell battery, even at high C‐rate and cycle duty.

“…Besides, the surface temperature distributions on a superior lithium polymer battery with lithium manganese nickel cobalt oxide cathode material (16 Ah capacity) at different discharge rates were further studied by Panchal et al, which indicated that the increased discharge rates could result in increased surface temperature distributions on the principal surface of the battery and decreased discharge capacity . Thus, the thermal management system is very necessary when the battery is susceptible to high rates of charging and discharging and operated in ultrahigh or low ambient temperatures . It is noted that the BTMS methods can be classified to several types including air cooling, liquid cooling, and phase change material (PCM) cooling‐based system …”

Summary The power battery as an indispensable part of electric vehicle has attracted much attention in recent years. Among these, the lithium‐ion battery is the most important option due to the high energy density, good stability, and low discharge rate. However, the thermal safety problem of lithium‐ion battery cannot be ignored. Therefore, it is very necessary to explore an effective thermal management system for battery module. Here, a thermal silica cooling plate‐aluminate thermal plate (SCP‐ATP) coupling with forced convection air cooling system as a thermal management system is proposed for improving the cooling performance of pouch battery module. The results reveal that the heat dissipating performance and temperature uniformity of pouch battery module with SCP‐ATP are greatly improved compared with other thermal management systems. Moreover, the highest temperature can be controlled below 50°C, and the temperature differences can be maintained with 3°C when the SCP‐ATP coupling forced convection is utilized to enhance the heat transfer coefficient. Furthermore, considering the cooling effectiveness and consumption cost comprehensively, the optimal air velocity of the SCP‐ATP coupling forced convection cooling system is 9 m/s. In addition, the SCP‐ATP filling with different proportions of acetone has also been investigated for pouch battery module, indicating that 50% acetone exhibited a better heat transfer effect than the 30% one. Therefore, this research would provide a significant value in the design and optimization of thermal management systems for battery module.
