摘要： This application provides a battery module, including a plurality of batteries, a first enclosing plate, and a second enclosing plate. The first enclosing plate includes a first side plate, a first front plate containing a first connecting hole, and a first rear plate containing a third connecting hole. The second enclosing plate includes a second side plate, a second front plate containing a second connecting hole, and a second rear plate containing a fourth connecting hole. The first connecting hole and the second connecting hole are fixedly connected to the first front plate and the second front plate by the fasteners. The third connecting hole and the fourth connecting hole are fixedly connected to the first rear plate and the second rear plate by the fasteners. Both the first enclosing plate and the second enclosing plate form a semi-enclosure structure, and tightly enclose the plurality of batteries. Merely two junctions exist between the two enclosing plates, thereby reducing risks of failure at the junctions and improving structural strength of the battery module. In addition, the first enclosing plate and the second enclosing plate are simply connected by the fasteners, thereby facilitating installation and disassembly and improving assembling efficiency.

摘要： The present invention provides a battery module and a manufacturing method thereof, a battery pack and a vehicle, the battery module comprises batteries and a thermistor. Each battery comprises a cap plate, a positive electrode terminal, a negative electrode terminal and a vent, the vent is positioned between the positive electrode terminal and the negative electrode terminal. The cap plate comprises a first boundary away from the positive electrode terminal, and the vent comprises a third boundary close to the positive electrode terminal. The thermistor is positioned between the first boundary and the third boundary. Because the positive electrode terminal and the location around the positive electrode terminal are high in temperature, therefore when the thermistor collects the temperature of the battery, it greatly reduces the deviation between the collected temperature obtained by the thermistor and the actual temperature of the battery, thereby improving the accuracy of temperature sampling.
