The invention relates to a battery module. The battery module comprises at least one battery cell (2), in particular a lithium-ion battery cell, and a cooling plate (3) connected to the at least one battery cell (2) in a heat-conducting manner, wherein a heat balance layer (4) used to improve thermal conductance between the between the at least one battery cell (2) and the cooling plate (3) is arranged between the at least one battery cell (2) and the cooling plate (3). The heat balance layer (4) is formed of a base material (5) and further comprises at least one phase change material (6). At least a polymer actuator has conversion temperature above 20 DEG C. 本发明涉及种电池组模块，所述电池组模块包括：至少个电池组电池(2)、尤其锂离子电池组电池，和与所述至少个电池组电池(2)导热连接的冷却板(3)，其中，在所述至少个电池组电池(2)和所述冷却板(3)之间还布置有构造用于提高所述至少个电池组电池(2)和所述冷却板(3)之间的导热能力的热均衡层(4)，其中，所述热均衡层(4)由基础材料(5)构造并且还包括至少个相变材料(6)，所述至少个聚合物致动器具有高于20℃温度的转换温度。
