Therefore, it is necessary to determine whether the battery cell is still intact and whether the electrical connection between the battery cell and the charging interface is stable in the portable power source with a good appearance.
Therefore, an external power supply can be connected to the charging interface, the voltage value at the charging interface is detected twice, the absolute value of the difference between the two values is calculated, the absolute value is compared with a preset value (such as 10), and when the absolute value is larger than or equal to 10, the fact that no battery cell exists in the mobile power supply is indicated; it can also be stated that the battery cell is arranged inside the mobile power supply, but the electric connection between the battery cell and the charging interface is not stable. When the absolute value is smaller than 10, the detection and judgment operations are circulated again, and when the circulation frequency reaches a preset frequency (such as 10), it is indicated that a battery cell is arranged in the mobile power supply, and it can also be indicated that the electric connection between the battery cell in the mobile power supply and the charging interface is stable.
Of course, the above method generally adopts program motion, and the absolute value of the time difference between two detections should not be too large or too small, and generally the range of the absolute value of the difference between the two is between 0.5s and 1 s. The embodiments described above with reference to fig. 1-8 also describe this method in detail, and are not described herein again.
