Abstract: The present disclosure provides a battery module, a manufacturing method of the battery module 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.
