The humidity sensor 15 is connected to the BMS of the self-dehumidifying battery assembly. Its advantages are: the humidity sensor 15, connected to the BMS, can monitor the humidity inside the battery in real time and feed the data back to the BMS, allowing the BMS to take appropriate measures based on the humidity, such as reminding the user to replace the desiccant 12, thereby ensuring the battery is always in a good working environment. Furthermore, in this embodiment, the removable cover 14 also includes a signal transmission line 151, one end of which is connected to the humidity sensor 15, and the other end is led out from the removable cover 14 and connected to the BMS.

[0071] In some possible embodiments of this utility model, such as Figure 4 As shown, the self-dehumidifying battery assembly also includes an alarm electrically connected to the battery management system (BMS). When the humidity sensor 15 exceeds a threshold, the BMS controls the alarm to remind the user to replace the desiccant 12 in a timely manner. The beneficial effect is that when the humidity detected by the humidity sensor 15 exceeds the set threshold, the BMS controls the alarm to remind the user to replace the desiccant 12 in a timely manner. This proactive reminder mechanism can effectively avoid battery performance degradation or damage caused by desiccant 12 failure, thereby improving the reliability and maintenance efficiency of the self-dehumidifying battery assembly.
