Description

Technical Field

[0001] The present invention relates to the field of solar charging technology, and in particular to a method for improving the life of a battery component in a low-temperature environment, a terminal device and a medium. Background Art

[0002] Existing solar multi-battery products can achieve balanced charging of each battery pack when the temperature is in normal mode. However, when the battery pack is in a low temperature environment for a long time, auxiliary heating is required before charging. Due to the large power consumption of auxiliary heating, it is difficult for solar energy input to heat all battery packs at the same time. Only some battery packs can be heated and charged first. At this time, the problem of uneven charging of each battery pack will arise. Over time, some batteries have been in use while some have not been used, resulting in a reduction in the overall battery pack life.

[0003] When the solar input power of these solar multi-battery products is relatively low for a long time, the hardware will charge each battery pack evenly. However, since the input power itself is relatively small, it will be even smaller when it is allocated to each battery. This will cause each battery to be charged at a very low power. In the long run, each battery will be constantly charging. Since battery charging has a lifespan issue and the number of charging times, it will reduce the battery life. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a method for improving the life of a battery assembly in a low temperature environment, a terminal device and a medium.

[0005] The specific plan is as follows:

[0006] A method for improving the life of a battery component in a low temperature environment comprises the following steps:

[0007] S1: Initialize the state of all battery components in the solar charging system in the low temperature environment to be in an unheated state;

[0008] S2: Real-time detection of the output power of the solar charging panel;

[0009] S3: Calculate the number N of battery assemblies that can be charged according to the current output power;

[0010] S4: setting the charging priority of all battery assemblies in an unheated state according to the SOC value of each battery assembly, and sorting the charging priority of each battery assembly in descending order;

[0011] S5: Turn on heating for the battery components with the top NM charging priorities, where M represents the number of battery components being heated, and change the status of these battery components to heating; detect the temperature of the battery components in the heating status in real time, and charge these battery components when their temperature is greater than a first temperature threshold. When the charging of a battery component is completed, change the status of the battery component to unheated, and return to S3; when their temperature is greater than a second temperature threshold, stop heating these battery components.

[0012] Furthermore, the number N of battery assemblies that can be charged should satisfy: the current output power is greater than or equal to the power required by the N battery assemblies, and the power required by a single battery assembly is the sum of the power required for heating the battery assembly and the power required for charging.

[0013] Furthermore, when setting the charging priority of each battery assembly according to the SOC value of each battery assembly, the charging priority of the battery assembly with a larger SOC value is set to be lower.

[0014] Furthermore, the first temperature threshold is 5 degrees Celsius, and the second temperature threshold is 15 degrees Celsius.

[0015] Furthermore, step S3, while calculating the number N of battery assemblies that can be charged, also includes recording the output power used to calculate the number N of battery assemblies that can be charged; step S5 also includes: real-time judgment on whether the change in the currently detected output power relative to the recorded output power is greater than the power required by a single battery assembly, and if so, returns to S3.

[0016] Furthermore, the low temperature environment is an environment temperature below 15 degrees Celsius.

[0017] A terminal device for improving the life of battery components in a low-temperature environment includes a processor, a memory, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the method described above in the embodiment of the present invention are implemented.

[0018] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method described above in an embodiment of the present invention are implemented.

[0019] The present invention adopts the above technical solution, which can ensure that each battery component has the same charging probability in a low temperature environment and achieve charging balance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To further illustrate various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in this field should be able to understand other possible implementations and advantages of the present invention.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0023] Embodiment 1:

[0024] The embodiment of the present invention provides a method for improving the life of a battery component in a low temperature environment. Figure 1 As shown, the method comprises the following steps:

[0025] S1: Initialization: All battery components in the solar charging system in a low temperature environment are in an unheated state.

[0026] In this embodiment, an ambient temperature below 15 degrees Celsius is set as a low temperature environment. At this time, the battery assembly needs to be heated to 15 degrees Celsius to facilitate normal charging.

[0027] S2: Real-time detection of the output power of the solar charging panel.

[0028] S3: Calculate the number N of battery assemblies that can be charged according to the current output power.

[0029] In this embodiment, the number N of battery assemblies that can be charged should satisfy the following requirements: the current output power is greater than or equal to the power required by the N battery assemblies, and the power required by a single battery assembly is the sum of the power required for heating the battery assembly and the power required for charging.

[0030] S4: setting the charging priority of all battery assemblies in an unheated state according to the SOC (charging rate) value of each battery assembly, and sorting the charging priority of each battery assembly in descending order.

[0031] In this embodiment, the battery assembly with a larger SOC value is set to have a lower charging priority.

[0032] S5: Turn on heating for the battery components with the top NM charging priorities, where M represents the number of battery components being heated, and change the status of these battery components to heating; detect the temperature of the battery components in the heating status in real time, and charge these battery components when their temperature is greater than a first temperature threshold. When the charging of a battery component is completed, change the status of the battery component to unheated, and return to S3; when their temperature is greater than a second temperature threshold, stop heating these battery components.

[0033] Since only the battery components in the unheated state are sorted during sorting, the battery components in the heating state have already entered the heating and charging process. Therefore, when there is additional power (that is, NM additional battery components can be added for heating and charging), it is only necessary to operate the battery components with the top NM charging priorities, and the M battery components that were previously in the heating state can maintain their previous operations.

[0034] In this embodiment, the first temperature threshold is set to 5 degrees Celsius, indicating that charging can be started when this temperature is reached; the second temperature threshold is set to 15 degrees Celsius, indicating that normal charging can be performed when this temperature is reached.

[0035] The temperature of the battery assembly can be detected by using a temperature sensor installed in the battery assembly. Usually, the temperature sensor is installed in the charging meter.

[0036] Furthermore, in this embodiment, step S3, while calculating the number N of battery assemblies that can be charged, also includes recording the output power used to calculate the number N of battery assemblies that can be charged; step S5 also includes: determining in real time whether the change in the currently detected output power relative to the recorded output power is greater than the power required by a single battery assembly, and if so, returning to S3. In this way, it can be ensured that when the output power increases, the number of battery assemblies that can be charged is increased in a timely manner, thereby improving the utilization rate of solar energy.

[0037] Through the method of this embodiment, in a low temperature environment, when the output power of the solar charging panel remains unchanged, the battery components with a low charging rate can be charged first; as the output power of the solar charging panel gradually increases, the number of battery components that can be charged simultaneously can be gradually increased on the basis of sorting by charging priority; when a battery component is fully charged, the charging priority of the battery component will become the lowest, thereby realizing a cycle, ensuring the consistency of the charging probability of each battery component, and achieving charging balance.
