A charging abnormality determination method for determining whether the charging of the battery pack 20 on the charging stand 10 as above is abnormal or not is described below, and includes

steps

1010, 1020, and 1030 as shown in fig. 5.

Wherein, step 1010: the signal processing host 200 receives the smoke detection signals from the smoke detection devices 110 of the respective charging potentials 100 and the temperature detection signals from the plurality of temperature detection points of the temperature detection device 120.

Step 1020: the signal processing host 200 determines whether the smoke detection signal and the temperature detection signal are normal, and if at least one of the smoke detection signal and the temperature detection signal is abnormal, step 1030 is performed; if the smoke detection signal and the temperature detection signal are both normal, step 1030 is not performed. The phrase "not executing step 1030" in this paragraph means that the smoke detection signal and the temperature detection signal are both normal and do not trigger the execution of step 1030, but does not exclude the possibility of other conditions triggering step 1030. Generally, the smoke detection signal and the temperature detection signal are normal, and the process returns to step 1010.

Step 1030: the signal processing host 200 sends the abnormal signal to the alarm device 300, and the alarm device 300 gives an alarm.

As shown in fig. 6, in step 1020, the signal processing host 200 determines whether the smoke detection signal and the temperature detection signal are normal respectively. The signal processing host 200 determining whether the temperature detection signal is normal includes the following steps: the signal processing host 200 determines whether the temperature of the single charge level 100 to be determined is normal according to the plurality of temperature data of the plurality of temperature detection points of the temperature detection device 120 of the single charge level 100 to be determined, and specifically includes

steps

1021 and 1022.

Step 1021: comparing any two temperature data in the multiple temperature data of the single charge level 100 to be judged, if at least one difference value of any two temperature data of the single charge level 100 to be judged is greater than a first threshold value, judging that the single charge level 100 to be judged is abnormal, and executing step 1030; if the difference between any two temperature data of the single charge level 100 to be determined is less than or equal to the first threshold, step 1022 is executed.

Step 1022: sequentially comparing the temperature average value of the plurality of temperature data of the single charge level 100 to be judged with the temperature average value of the plurality of temperature data of each of the other charge levels 100, judging whether the difference value between the temperature average value of the single charge level 100 to be judged and the temperature average value of each of the other charge levels 100 exceeds a set number or not, if yes, judging that the single charge level 100 to be judged is abnormal, and executing step 1030; if not, then step 1030 is not performed. The phrase "not executing step 1030" in this paragraph means that the temperature data is normal and does not trigger the execution of step 1030, but does not exclude the execution of step 1030 due to an abnormal smoke detection signal and does not exclude the possible triggering of step 1030 by other conditions. As shown in fig. 6, if the temperature detection signal is finally determined to be normal, the process returns to step 1010.

The present invention is not limited to the

above steps

1021, 1022. In an alternative embodiment, after the temperature data is determined to be normal in step 1022, another calculation method different from that in both

steps

1021 and 1022 may be further adopted to determine whether the temperature data is abnormal or not.

In this embodiment, the temperature data of the plurality of temperature detection points of the single charge level 100 to be determined is not classified and is calculated at a time.

In an alternative embodiment, the plurality of temperature detection points of the single charge level to be determined include a plurality of first temperature detection points and a plurality of second detection points, data of the first detection points are first temperature data, and data of the second detection points are second temperature data. When the battery pack is charged, the charging position can be divided into a high-temperature area and a low-temperature area, so that the first detection point can be arranged in the high-temperature area, and the second detection point can be arranged in the low-temperature area. The judging process comprises the following steps: the signal processing host machine respectively judges whether the first temperature data and the second temperature data of a single charging potential to be judged are normal, if at least one of the first temperature data and the second temperature data is abnormal, an alarm step is executed; and if the first temperature data and the second temperature data are normal, the alarming step is not executed. The phrase "not executing an alarm step" in this paragraph means that the temperature data is normal and the alarm step is not triggered, but does not exclude the alarm step being executed because the smoke detection signal is abnormal and does not exclude the alarm step being triggered by other conditions that may exist.

In alternative embodiments, the plurality of temperature detection points of the single charge level to be determined may be divided into three, four, or more groups. Similar to the method shown in fig. 6, the temperature detection data of each group of temperature detection points are compared in a group, and are judged according to the difference between any two temperature detection points in the group; then, a certain group of temperature average values of the single charging potentials to be judged and the same group of temperature average values of the other single charging potentials can be sequentially compared, and judgment is carried out according to the number of the difference values larger than a certain threshold value. The difference between different groups of data of the single band judgment charging potential can be judged by adopting an inter-group comparison method.

In addition, the present embodiment also provides a charging station, which includes at least one charging rack 10 as above.

Meanwhile, the embodiment also provides an energy storage station which comprises at least one charging rack 10.

Example 2

The charging stand 10 of the present embodiment is substantially the same as the charging stand 10 of embodiment 1. The difference is that the optical fiber temperature sensing device does not include the fiber grating 121 described in embodiment 1, but includes a raman fiber, and a plurality of temperature detection points are distributed in the raman fiber.

In one embodiment of this embodiment, the raman fiber 123 has a spiral shape, as shown in fig. 7. In another embodiment of this embodiment, raman fiber 123' has a cyclically reciprocating S-shape, as shown in fig. 8. Therefore, the coverage area of the Raman fiber can be more comprehensive. In alternative embodiments, the raman fiber may be arranged in other manners, such as a zigzag shape, and the like, so as to substantially cover the detection region required by the battery pack. Another difference is that the temperature detection points of the raman fiber do not necessarily cover all of the relief valves 21 of the battery pack 20.

Example 3

The charging stand 10 of the present embodiment is substantially the same as the charging stand 10 of embodiment 1. The difference is that the temperature detecting device 120 of the present embodiment is not an optical fiber temperature sensing device, but includes a plurality of infrared temperature detectors 124, and each infrared temperature detector 124 is distributed at each temperature detecting point. The plurality of infrared temperature detectors 124 are also precisely positioned and arranged as generally shown in fig. 9, which is a bottom view.
