1. A battery module, comprising:
a battery cell;
a circuit board, disposed at a top of the battery cell and electrically connected to the battery cell;
a temperature sensor, disposed at the top of the battery cell and configured to measure a temperature of the battery cell, wherein the temperature sensor is electrically connected to the circuit board; and
a fixing component, wherein the fixing component comprises a fixing portion and a rotation portion, the fixing portion is fixed to the top of the battery cell, and the rotation portion is screwed into the fixing portion whereby the temperature sensor is pressed against the battery cell tightly,
wherein the fixing portion comprises an inner cavity and a mating slot, the inner cavity runs through to the top of the battery cell, the temperature sensor is accommodated in the inner cavity, the mating slot extends in a circumferential direction of the inner cavity and slants in a radial direction of the inner cavity, the mating slot is disposed centrosymmetrically on a side wall of the inner cavity,
wherein the rotation portion comprises a spindle and two bulges symmetrically disposed on two sides of the spindle, the two bulges protrude from the spindle, and are screwed into the fixing portion along the mating slot,
wherein the mating slot comprises two mating slot sections, each one of the two mating slot sections has an end away from the battery cell and an end close to the battery cell, two notches are disposed on an inner side wall of the mating slot, each one of the two notches is disposed at the end of one of the two mating slot sections close to the battery cell, each one of the two notches is recessed in the inner side wall of the mating slot, and the two bulges are located in the two notches, respectively.
