As shown in fig. 3, the battery test method includes:
In this embodiment, in the process of charging or discharging the electronic device, a first charging characteristic peak position and a first discharging characteristic peak position of the battery are obtained, and when a difference between the first charging characteristic peak position and a first preset peak position is smaller than a first preset threshold value, and a difference between the first discharging characteristic peak position and a second preset peak position is smaller than the first preset threshold value, it is indicated that there is no deviation or a small deviation between the first charging characteristic peak position and the first preset threshold value, and there is no deviation or a small deviation between the first discharging characteristic peak position and the first preset threshold value. That is, the kind of the battery mounted on the electronic device is the same as the kind of the battery mounted on the electronic device when the electronic device is shipped. The battery assembled when the electronic equipment leaves the factory is generally subjected to safety certification by a manufacturer, so that the safety of the battery can be ensured, and the safety of a user when the electronic equipment is used is ensured.
In this embodiment, after obtaining the first charge characteristic peak position and the first discharge characteristic peak position of the battery according to the anode, the cathode and the reference electrode, the method further includes: the difference value between the first charging characteristic peak position and the first preset peak position is greater than or equal to a first preset threshold value; or when the difference value between the first discharge characteristic peak position and the second preset peak position is greater than or equal to a first preset threshold value, outputting prompt information; wherein, the prompt message includes: the battery is at least one of non-original, the electronic equipment is turned off, and the charging characteristic peak position and the first discharging characteristic peak position are uploaded to the server.
The difference value between the first charging characteristic peak position and the first preset peak position is greater than or equal to a first preset threshold value; or when the difference value between the first discharge characteristic peak position and the second preset peak position is greater than or equal to the first preset threshold value, the difference value between the characteristic peak position and the first preset threshold value is larger, the battery assembled on the electronic equipment at present is considered to be a non-original battery, the type of the non-original battery is different from the type of the battery assembled when the electronic equipment leaves a factory, in order to avoid safety accidents in the using process, when the battery assembled on the electronic equipment is determined to be the second type battery, the electronic equipment can send prompt information to prompt a user that the battery assembled on the electronic equipment at present is possibly a fake battery, the user is reminded of replacing the battery in time, and the safety of the user when the electronic equipment is used is further improved by reminding the user.
For example, the prompt message may be a battery that is not a genuine battery, a display screen of the electronic device displays a word that the battery may be a counterfeit battery, and a user may replace the battery or perform a shutdown operation after viewing the prompt message.
The prompt information can also be used for turning off the electronic equipment, so that the user is prompted to turn off the electronic equipment in time to avoid danger caused by using a fake battery, and the safety of the user is ensured.
The prompt message may also be to upload the first charging characteristic peak position and the first discharging characteristic peak position to the server. The target server can be a cloud server of a manufacturer of the original battery in the electronic equipment, the target server can also be a cloud server of a related supervision part, the characteristic peak positions of the fake batteries are stored in a database of the target server, and the database counts a large amount of data, so that the type of the fake batteries which are used in large quantities can be determined according to the characteristic peak positions, and the fake batteries can be used as the basis for maintaining legal rights in the future.
In one possible application, the prompt message may be at least one of an audible message, a textual message, or a vibratory message.
In a possible application, if the electronic equipment is currently assembled with a non-genuine battery, but the current assembled battery adopts a battery core system the same as that of a genuine battery, in order to reduce the cost, a counterfeit manufacturer adopts a poor process, so that due to differences in the process, the difference between the characteristic peak position and the preset threshold value is within a specified range, but as the battery ages, the difference in the process begins to be expressed on the performance of the battery core, and within a 300-500 cycle period, the difference between the characteristic peak position and the preset threshold value exceeds the specified range, so that a user is prompted about the non-genuine battery core, and further, the safety risk caused by the aging of the battery core along with the increase of the service time is reduced.
In the embodiment, the characteristic peak position of the battery is detected in each charging or discharging process, so that the situation that the forged battery is mistakenly identified as the original battery due to single detection error is avoided.
As shown in fig. 4, the two lines in the graph are a potential variation curve detected when the battery is shipped from factory and a potential variation curve detected when the battery is in use by the electronic device, and the characteristic peak position deviation of the two curves is large, which indicates that the battery used by the electronic device is a non-original battery.
In a possible embodiment, after outputting the prompt message, the method further includes: and when the time length after the prompt information is output reaches the set time length, the electronic equipment is closed.
In this embodiment, when it is determined that the battery assembled on the electronic device is a non-genuine battery, although the electronic device may send the prompt message, since the user is not near the electronic device, the user may not obtain the prompt message of the electronic device in time, and in order to avoid a safety accident, within a preset time period after the prompt message is sent, if the user does not detach the battery or perform a shutdown operation, the electronic device may automatically perform a shutdown operation. The safety performance of the counterfeit battery is poor, for example, the temperature of the battery may be sharply increased during the charge or discharge process, and a problem of explosion or damage to the main board occurs. The electronic equipment improves the safety of the electronic equipment in an automatic shutdown mode.
Or even if the user sees the prompt message, the user may forget to replace the battery or leave luck not to replace the battery, and in order to ensure the safety of the user, the electronic equipment can also execute the automatic shutdown operation within the preset time after the prompt message is sent.
In a possible application, when a user restarts the electronic device after finding that the electronic device is automatically turned off, the electronic device will continue to pop up information indicating whether the battery is a counterfeit battery or not and to prevent the user from using the electronic device with low safety for a long time.
