In one embodiment, FIG. 4 is a flow chart of reducing the charging power of a battery in one embodiment. As shown in fig. 4, the method for reducing the charging power of the battery according to the number of the gas leakage points and the gas concentration value of the battery comprises the following steps:
The first concentration difference in the first time period is a concentration difference corresponding to the concentrations of the ending time point and the starting time period of the first time period. The second time period may be a next time period adjacent to the first time period, or a backward time period separated from the first time period by a preset time period.

Specifically, when the sensor is inside the cell and the second concentration difference is greater than the first concentration difference, i.e., the cell internal and external concentrations have not yet reached equilibrium, the cell is still continuously producing gas. When the sensor is outside the battery and inside the electronic device, and the second concentration difference is greater than the first concentration difference, i.e., the internal and external concentrations of the battery have not yet reached equilibrium, likewise, the battery gas continues to leak. It may also mean that the rate at which the gas is continuously produced by the battery is greater than the rate at which the gas leaks from the battery.

Wherein the value of the gas pressure, also called the gas pressure, is due to a continuous, irregular impact of a large number of gas molecules against the wall of the container. When the battery is subjected to phenomena such as bag expansion, the air pressure in the battery is increased. When the battery leaks, the gas in the battery is released until the gas pressure is balanced with the outside.
The pressure change value may refer to a pressure change difference value, or a pressure change rate. The pressure variation difference is a difference between the first pressure difference and the second pressure difference. The rate of change of pressure refers to the rate of change from a first pressure difference value to a second pressure difference value. Rate of change of pressure = (second pressure difference value-first pressure difference value)/first pressure difference value. Or the pressure change rate = (second pressure difference value-first pressure difference value)/first pressure difference value/time period, etc., are not limited thereto.
When the sensor is inside the battery and the second pressure difference is greater than the first pressure difference, that is, the internal pressure and the external pressure of the battery are not balanced yet, and the battery continues to generate gas. When the sensor is outside the battery and inside the electronic device and the second pressure difference is greater than the first pressure difference, that is, the internal pressure and the external pressure of the battery are not balanced, the battery gas continuously leaks. It may also mean that the rate at which the gas is continuously produced by the battery is greater than the rate at which the gas leaks from the battery. Then, the electronic device finds the corresponding battery charging power according to the pressure variation value and the number of the air leakage points.
In this embodiment, the pressure change value is a pressure change rate. The electronic equipment processes the pressure change rate and the number of the air leakage points to obtain the charging power value of the battery. And setting the pressure change rate as A and the number of air leakage points as B, and obtaining the pressure change rate of each air leakage point according to A/B. Assuming that the charging power in the first period is P1 and the charging power in the second period is P2, P2= P1 × (1-a/B) and the like are not limited thereto. That is, when A/B is greater than 0, P2 is less than P1.
In this embodiment, the pressure change value is a pressure change rate. The electronic device processes the pressure change value and the number of air leakage points to obtain a reduced target charging power difference value. And setting the pressure change rate as A and the number of air leakage points as B, and obtaining the pressure change rate of each air leakage point according to A/B. Assuming that the charging power in the first period is P1, the target power difference = P1 × a/B, etc., is not limited thereto. Then, the greater the rate of change in the concentration, the smaller the charging power is, the more; the smaller the rate of change in the concentration, the less the charging power is reduced.
In the battery air leakage processing method in this embodiment, a first pressure difference value in a first time period and a second pressure difference value in a second time period are obtained, a pressure change value is obtained according to the first pressure difference value and the second pressure difference value, when the second pressure difference value is greater than the first pressure difference value, the charging power of the battery is reduced according to the pressure change value and the number of air leakage points of the battery, the charging power of the battery can be controlled according to the pressure change speed, the accuracy of battery air leakage processing is improved, the stability of the battery during charging can be improved, and the charging speed is ensured while the battery is prevented from exploding.

Wherein the environmental gas parameter value refers to a physical parameter value of the environmental gas. For example, the ambient gas parameter value may be, but is not limited to, an ambient gas concentration or an ambient gas pressure. Both the cell gas concentration and the ambient gas concentration may be the concentration of a certain gas. For example, the gas is sulfuric acid mist, lithium oxide, or the like, but is not limited thereto.

When the battery gas parameter value is detected to be larger than the environment gas parameter value, and the difference value between the battery gas parameter value and the environment gas parameter value is larger than the preset parameter difference value, the electronic equipment determines that the battery leaks gas.
In this embodiment, the battery may exchange gas with the environment when the electronic device is used for a long time.

But when the cell leaks the cell gas parameter value may be much larger than the ambient gas parameter value.
According to the battery gas leakage processing method in the embodiment, the environmental gas parameter value is obtained, when the battery gas parameter value is larger than the environmental gas parameter value and the difference value between the battery gas parameter value and the environmental gas parameter value is larger than the preset parameter difference value, the battery gas leakage is determined, the influence of the environment can be considered, the phenomenon of gas leakage caused by misjudgment is avoided, and the accuracy of battery gas leakage processing is improved.

In one embodiment, the battery leakage treatment method further comprises: and when the target scene is a second preset scene, determining that the battery is not leaked, wherein the gas parameter value in the second preset scene is larger than the gas parameter value in the first preset scene.
Specifically, the second preset scenario may be a scenario with a large gas parameter value, such as a factory. The gas parameter value in the second preset scene is larger than that in the first preset scene. Under the long-term use condition of the battery, the electronic device where the battery is located may generate gas exchange with the second preset scene, so that the gas parameter value of the battery is larger. Then the electronic device determines that the battery is not leaking when the target scene is a second preset scene.
