Abstract: A battery module includes a first battery bracket, a second battery bracket, and a liquid cold heat-dissipating mechanism. The first battery bracket and the second battery bracket are stacked on each other. Each of the first battery bracket and the second battery bracket includes plural hollow portions for accommodating plural battery cells. The liquid cold heat-dissipating mechanism is used for removing heat from the plural battery cells. The liquid cold heat-dissipating mechanism includes an input channel, an output channel, a first flow-channel plate, at least one first connecting member, and at least one second connecting member. After a cooling liquid is introduced into the input channel, the cooling liquid is sequentially transferred through the first end of the first flow-channel plate, the first flow channel, the second end of the first flow-channel plate and the second connecting member, and discharged from the output channel.

Abstract: A battery module includes a housing, a plurality of thermally conductive plates, a plurality of flat cells and a fixing unit. The thermally conductive plates and the flat cells are received in the housing. At least one of the thermally conductive plates is received between two of the flat cells and contacts with at least one of the two of the flat cells. Each of the flat cells respectively has a cell body and at least an electrode connected to and extended from the cell body. The fixing unit is received in the housing, and the electrode is fixed on the fixing unit. The battery module is applied advantageously to integrate the thermal dissipation system with the fixing structure. Additionally, the particular configuration used herein is beneficial to reduce the risk of electrode breakage.
