Abstract: A hybrid BTMS considering heat dissipation and mechanical protection for prismatic battery modules is constructed, which combines the modularized liquid-cooling plate (MLCP) and the phase change material (PCM)-negative Poisson's ratio structural laminboard. The effects of interior structure, flow direction, flow rate, and cooling strategy of the MLCP on the thermal performance of the battery module were investigated. It showed that the proposed MLCP was able to weaken the heating effect of coolant along the flow path by more than 50 % through modularized design. Furthermore, the alternating cooling strategy of sub-domains of MLCP was designed, which halved the energy consumption of liquid cooling systems. In comparison to the case without the laminboard, the maximum temperature and temperature difference of the case with it were reduced by 3.79 °C and 2.50 °C, respectively. Meanwhile, the maximum stress and total deformation of the battery cell were also decreased by 1.67 MPa and 78.1 μm with the protection of the laminboard at 1000 N. With the MLCP and the multifunctional laminboard, the maximum temperature and temperature difference of the battery module were kept below 35 °C and 4 °C, respectively, even at a high discharge current of 100 A and under dynamic conditions.
