In the prior art, the battery after the soaking process is usually disassembled, and the degree of humidity inside the battery is observed to determine whether the battery is sufficiently soaked. However, since the electrolyte is colorless liquid, it is difficult to accurately observe the degree of wetness inside the battery with naked eyes, and it is impossible to accurately determine how long the battery needs to be soaked sufficiently.
In view of the above problems, an embodiment of the present invention provides a method, an apparatus, an electronic device, and a storage medium for detecting battery wetting time, where the method includes: monitoring the voltage between the positive electrode and the negative electrode of the primary battery pole group in the process of carrying out infiltration treatment on the battery to be detected; when the voltage between the positive electrode and the negative electrode of the original battery electrode group reaches a preset nominal voltage, determining that the battery to be tested is fully infiltrated in the horizontal direction, and recording first infiltration time; monitoring the discharge capacity of the primary battery pole group after determining that the battery to be tested is fully infiltrated in the horizontal direction; when the discharge capacity of the original battery pole group reaches the preset discharge capacity, determining that the battery to be tested is fully infiltrated in the thickness direction, and recording second infiltration time; and determining the total sufficient soaking time of the battery to be tested according to the first soaking time and the second soaking time.

These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The embodiment of the application provides a battery infiltration time detection method, which is applied to a battery detection system, wherein the battery detection system comprises a battery to be detected and a primary battery pole group, the primary battery pole group is embedded in a preset most difficult infiltration position of the battery to be detected, and the method is used for detecting the total time of sufficient infiltration of the battery to be detected. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, and other electronic devices that can be used for detecting the soaking time of the battery to be tested.
As shown in fig. 1, a schematic flow chart of a method for detecting a battery wetting time provided in an embodiment of the present application is shown, where the method includes:
Specifically, the battery to be tested with the primary battery electrode group embedded therein may be subjected to a liquid injection process, the battery to be tested is injected with liquid, and then the battery to be tested is placed in an environment set by a normal process, for example, the battery is placed at a temperature of 25 ℃ until the electrolyte is soaked, and the start time of the soaking process of the battery to be tested is recorded.
Specifically, the positive and negative leads of the primary battery electrode group may be connected to a preset electric energy meter in advance, so as to monitor the voltage between the positive and negative electrodes of the primary battery electrode group based on the preset electric energy meter. The primary battery is a battery device which generates current through chemical reaction and cannot be charged, and a battery pole group consists of a positive pole, a negative pole and a diaphragm, is in a non-liquid injection state of the battery and is also an assembly part of the battery.
It should be noted that the primary battery pole group employs: the positive electrode is made into an electrode by mixing (such as a main material conductive agent PVDF/PTFE =85 10): thickness < 0.5mm, area =4cm 2 . Because the original battery pole group adopts the lithium battery, after the lithium battery is fully soaked in the horizontal direction, the voltages of the positive pole and the negative pole of the lithium battery reach the preset nominal voltage, the nominal voltages of different battery systems of the lithium battery are slightly different, and the preset nominal voltage is generally not lower than 3.0V.
Specifically, when the voltage between the positive electrode and the negative electrode of the primary battery pole group reaches the preset nominal voltage corresponding to the primary battery pole group, the horizontal infiltration of the primary battery pole group is represented to be sufficient. Because the primary battery pole group is embedded in the preset most difficult-to-soak position of the battery to be tested, the battery to be tested is soaked fully in the horizontal direction under the condition that the primary battery pole group is soaked fully in the horizontal direction, and the first soaking time is recorded. And the time difference between the first soaking time and the beginning time of the soaking treatment of the battery to be detected is the full soaking duration of the battery to be detected in the horizontal direction.
And 103, monitoring the discharge capacity of the primary battery pole group after the battery to be tested is fully infiltrated in the horizontal direction.
It should be noted that, because the primary battery electrode group used is a lithium battery, and only can discharge and cannot be charged, in order to detect whether the thickness direction of the primary battery electrode group is sufficiently infiltrated, the primary battery electrode group that is being infiltrated can be discharged to monitor the overall discharge capacity.
And step 104, when the discharge capacity of the original battery pole group reaches the preset discharge capacity, determining that the battery to be tested is fully infiltrated in the thickness direction, and recording second infiltration time.
The preset discharge capacity is determined according to the battery composition and the battery model of the primary battery pole group.
Specifically, when the discharge capacity of the primary battery pole group reaches a preset discharge capacity, the primary battery pole group is fully infiltrated in the thickness direction. Because the primary battery pole group is embedded in the preset most difficult-to-soak position of the battery to be tested, the battery to be tested is soaked in the thickness direction sufficiently under the condition that the primary battery pole group is soaked in the thickness direction sufficiently, and the second soaking time is recorded. And the time difference between the second soaking time and the first soaking time is the sufficient soaking time in the thickness direction of the battery to be tested.
And 105, determining the total sufficient infiltration time of the battery to be tested according to the first infiltration time and the second infiltration time.
Specifically, the full-infiltration duration in the horizontal direction of the battery to be tested can be determined according to the first infiltration time, the full-infiltration duration in the thickness direction of the battery to be tested can be determined according to the second infiltration time, and the sum of the full-infiltration duration in the horizontal direction of the battery to be tested and the full-infiltration duration in the thickness direction is the full-infiltration total duration of the battery to be tested.
Further, in an embodiment, after determining the total time of sufficient infiltration of the battery to be tested, the battery with the same type as the battery to be tested may be subjected to infiltration treatment for a corresponding time length according to the total time of sufficient infiltration, so as to ensure that the battery can be sufficiently infiltrated.
On the basis of the foregoing embodiments, as an implementable manner, in an embodiment, after determining that the battery to be tested is sufficiently infiltrated in the horizontal direction, monitoring the discharge capacity of the primary battery pole group includes:
step 1031, after determining that the battery to be tested is fully infiltrated in the horizontal direction, performing discharging operation on the primary battery pole group based on a discharging device connected with the primary battery pole group;
and step 1032, monitoring the discharge capacity of the primary battery pole group during the discharging operation of the primary battery pole group.
As shown in fig. 2, a schematic diagram of a relationship function between the standing real-time and the percentage of the discharge capacity of the primary battery pole group provided in the embodiment of the present application is shown, where the standing real-time is the infiltration time of the primary battery pole group. The discharge capacity of the primary battery pole group is evaluated by connecting discharge equipment with the positive and negative leads of the primary battery pole group, a plurality of batteries (such as 3 batteries) in the primary battery pole group can be tested at certain intervals, and when the average discharge capacity of the plurality of batteries reaches the preset discharge capacity of the primary battery pole group (namely 100 percent discharge capacity is reached), the primary battery pole group (the battery to be tested) is determined to be fully infiltrated in the thickness direction. Wherein the primary battery pole group can comprise 15 batteries in total.
Specifically, in an embodiment, in order to improve the discharge capacity monitoring efficiency of the primary battery pole group, so as to avoid repeatedly monitoring the discharge capacity of the primary battery pole group when the primary battery pole group definitely cannot reach the preset discharge capacity, the sufficient soaking time of the primary battery corresponding to the primary battery pole group can be obtained; after the battery to be tested is fully infiltrated in the horizontal direction, entering an infiltration waiting state in the thickness direction of the battery to be tested; and when the time length in the soaking waiting state in the thickness direction of the battery to be detected reaches the time length of full soaking of the primary battery, performing discharging operation on the primary battery pole group based on the discharging equipment connected with the primary battery pole group.
It should be noted that the sufficient infiltration duration of the primary battery corresponding to the primary battery pole group is the total duration of the primary battery pole group itself, and since the primary battery pole group is sheet-shaped, that is, the area in the horizontal direction is small, the total duration of the primary battery pole group itself is almost equal to the duration of the primary battery pole group itself in the thickness direction. In addition, because the primary battery pole group is embedded in the preset most difficult-to-soak position of the battery to be tested, the current primary battery pole group cannot be fully soaked in the full soaking time of the primary battery.
Specifically, in an embodiment, the sample of the primary battery electrode assembly may be subjected to an infiltration process, so as to obtain a sufficient infiltration duration of the sample of the primary battery electrode assembly.
The model of the primary battery pole group sample is the same as that of the primary battery pole group embedded in the battery to be tested.
Specifically, after it is determined that the battery to be tested is fully infiltrated in the horizontal direction, the battery to be tested enters an infiltration waiting state in the thickness direction, namely, the infiltration is continued, and after the continued infiltration time reaches the time length of the full infiltration of the primary battery, the discharging operation is performed on the primary battery pole group based on the discharging device connected with the primary battery pole group, so as to further judge whether the thickness direction of the primary battery pole group at the preset position which is most difficult to be infiltrated is fully infiltrated.
Specifically, in an embodiment, the discharge capacity of the primary battery pole group sample may be monitored during the process of performing the immersion treatment on the primary battery pole group sample; when the discharge capacity of the original battery pole group sample reaches a preset discharge capacity, determining that the original battery pole group sample is sufficiently soaked, and recording sample soaking time; and determining the sufficient sample soaking time of the primary battery pole group sample according to the starting time of the soaking treatment on the primary battery pole group sample and the sample soaking time.
The discharge capacity monitoring principle of the original battery pole group sample is the same as the discharge capacity monitoring principle of the original battery pole group, and specific reference is made to the above embodiments, which are not repeated herein.
It should be noted that, by detecting the battery infiltration time by using the method provided by the embodiment of the present application, two-dimensional infiltration effects can be shown, and due to the bonding reason of the battery electrode group, the infiltration effect in the thickness direction of the electrode plate is affected by the infiltration in the plane direction of the electrode plate, so that the battery infiltration effect can be more scientifically and more effectively evaluated by echelon analysis and two-dimensional analysis.
According to the method for detecting the battery infiltration time, provided by the embodiment of the application, the voltage between a positive electrode and a negative electrode of a primary battery pole group is monitored in the process of infiltrating a battery to be detected; when the voltage between the positive electrode and the negative electrode of the primary battery electrode group reaches a preset nominal voltage, determining that the battery to be tested is fully infiltrated in the horizontal direction, and recording first infiltration time; monitoring the discharge capacity of the primary battery pole group after determining that the battery to be tested is fully infiltrated in the horizontal direction; when the discharge capacity of the original battery pole group reaches the preset discharge capacity, determining that the battery to be tested is fully infiltrated in the thickness direction, and recording second infiltration time; and determining the total time of the full infiltration of the battery to be detected according to the first infiltration time and the second infiltration time. According to the method provided by the scheme, the infiltration effect of the primary battery pole group embedded in the position which is most difficult to infiltrate and preset in the battery to be detected is analyzed, whether the battery to be detected is sufficiently infiltrated after liquid injection is accurately judged, so that the battery can be infiltrated sufficiently after the time is accurately determined, the detection result can be used as a judgment value of the circulation time of the battery of the same type in the process, and the production efficiency of the battery is improved. And the infiltration effect of the battery to be detected is fully evaluated in two dimensions by detecting the positive and negative electrode voltages and the discharge capacity of the primary battery pole group, the infiltration of the battery pole piece to be detected in the plane direction and the infiltration of the battery pole piece in the thickness direction are systematically evaluated, the reliability of the detection result is improved, the situation that the discharge capacity is repeatedly monitored when the primary battery pole group does not reach the preset discharge capacity is avoided by predetermining the sufficient infiltration duration of the primary battery corresponding to the primary battery pole group is avoided, and the discharge capacity monitoring efficiency of the primary battery pole group is improved.
