Mechanism for cooling middle part and heating two ends of battery cell

The utility model discloses a middle cooling and two-end heating mechanism of a battery cell, relates to the technical field of battery thermal management systems, and provides the arrangement of the middle cooling and two-end heating mechanism of the battery cell, a cooling piece and a heating piece. The flow channels in the liquid cooling partition plates and the flow channels in the liquid cooling bottom plate are communicated with each other, so that the middle battery cell is cooled by the liquid cooling bottom plate and the liquid cooling partition plates at the same time, rapid cooling of the battery cell can be achieved under the dual cooling effect, the situation that the temperature rise rate of the battery cell in the middle of the module is high is relieved, and the performance of the battery cell is improved; when the temperature of the battery cells at the two ends is low, the PTC is started to heat the battery cells at the two ends, the condition that the temperature rise rate of the battery ce
