[0001] This invention belongs to the field of charging current and relates to a charging current adjustment method, device, electronic device, and readable storage medium. Background Technology

[0002] With the development of technology, lithium-ion battery packs for power tools are developing rapidly. More and more batteries capable of supporting high-rate charging currents are being used in power tool battery packs. However, although these batteries can output relatively high-rate charging currents, after being assembled into a battery pack, due to various limitations, most battery packs are prone to overheating and overvoltage risks when operating under high-rate charging current output conditions. This not only affects the lifespan of the battery cells but also the user experience and leaves safety hazards.

[0003] Therefore, it is necessary to provide improved technical solutions to overcome the above-mentioned technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of this application is to provide a charging current adjustment method, device, electronic device, and readable storage medium, which dynamically adjusts the charging current by real-time monitoring of battery pack voltage and temperature changes, thereby improving the charging rate of the battery pack and enhancing the user experience while ensuring that the voltage and temperature are within a safe range.

[0005] To achieve the above objectives:

[0008] Based on the parameters and characteristics of the battery pack, multiple voltage threshold ranges and multiple temperature threshold ranges are divided, and multiple charging current values ​​are set, with each charging current value corresponding to a voltage threshold range and a temperature threshold range.

[0009] The voltage threshold range corresponding to the sampling voltage and the temperature threshold range corresponding to the sampling temperature are determined, and then the charging current value corresponding to the sampling voltage and the sampling temperature is determined to be the target charging current value.

[0010] The target charging current value is sent to the charging device so that the charging device adjusts the charging current according to the target charging current value.

[0011] The adjustment method further includes:

[0012] The battery pack and / or charging device stores a preset reduction range for an intermediate temperature threshold, a maximum charging voltage threshold, and a preset reduction range for the charging current.

[0013] If the sampling voltage reaches the preset maximum charging voltage threshold and the sampling temperature is within the preset intermediate temperature threshold range, then the current charging current is reduced by a preset amount.

[0021] Maintain the reduced charging current until the sampled voltage reaches the maximum charging voltage threshold again.

[0022] In one embodiment, after the sampling voltage reaches the maximum charging voltage threshold again, the method further includes:

[0023] The process involves repeatedly reducing the current charging current by a preset amount and maintaining the reduced charging current until the sampled voltage reaches the maximum charging voltage threshold again, and until the charging current reaches the preset charging cutoff current.

[0024] In one embodiment, after the charging current reaches a preset charging cutoff current, the method further includes:

[0025] The system determines that the battery pack is fully charged and controls the charging device to stop outputting charging current.

[0026] Secondly, this application provides a charging current adjustment device, comprising:

[0027] The voltage and temperature detection module is used to acquire the sampled voltage and sampled temperature of the battery pack.

[0028] The threshold setting module is used to divide multiple voltage threshold ranges and multiple temperature threshold ranges according to the parameters and characteristics of the battery pack, and set multiple charging current values, each charging current value corresponding to a voltage threshold range and a temperature threshold range respectively.

[0029] The current value calculation module is used to determine the voltage threshold range corresponding to the sampling voltage and the temperature threshold range corresponding to the sampling temperature, and then determine the charging current value corresponding to the sampling voltage and the sampling temperature as the target charging current value.

[0030] A charging current adjustment module is used to send the target charging current value to the charging device so that the charging device adjusts the charging current according to the target charging current value.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of systems and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of the present invention may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0043] It should be understood that although the steps in the flowcharts of the embodiments of the present invention are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0044] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0045] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0046] like Figure 1 As shown in the figure, this application provides a charging current adjustment method, including:

[0047] Step S110: Obtain the sampling voltage and sampling temperature of the battery pack.

[0048] It is understandable that by collecting the sampling voltage (including the voltage of each group of batteries and the total voltage) and sampling temperature of the battery pack, and performing real-time voltage monitoring of the battery pack, the relationship between the voltage and the preset voltage threshold is analyzed to determine the current charging state of the battery. Since the increase in temperature will affect the chemical reaction rate and performance of the battery, when the temperature of the battery pack reaches the preset threshold, the charging current is adjusted to reduce the heat generation rate inside the cell, thereby preventing overheating.

[0049] Preferably, multiple sampling points can be arranged to reduce the impact of inconsistent temperature distribution of the battery pack at different times and under different conditions.

[0050] Step S120: Based on the parameters and characteristics of the battery pack, divide the battery pack into multiple voltage threshold ranges and multiple temperature threshold ranges, and set multiple charging current values, each charging current value corresponding to a voltage threshold range and a temperature threshold range.

[0051] It's understandable that when charging equipment charges a battery pack, it often uses the maximum current supported by the cells to shorten charging time. However, during the constant current phase of battery pack charging, the current remains constant, making the battery pack very prone to overheating. Once overheated, it takes a long time to recover to the rechargeable temperature. Therefore, by monitoring battery temperature and voltage in real time, the charging process of the battery pack can be adjusted, thereby regulating the charging current. Battery pack parameters and characteristics can include capacity, cell type, etc., and different battery pack parameters and characteristics do not affect the above steps.

[0052] Step S130: Determine the voltage threshold range corresponding to the sampling voltage and the temperature threshold range corresponding to the sampling temperature, and then determine the charging current value corresponding to the sampling voltage and the sampling temperature as the target charging current value.

[0053] It is understandable that by pre-setting the charging strategy of the battery pack, when receiving the sampled voltage and temperature information of the battery pack, the data is first pre-processed, and then the corresponding strategy is matched to output the current required charging current, thereby controlling the charging process of the battery pack.

[0054] Next, combine Figure 2 Explain the charging strategy. For example... Figure 2 The diagram shown is a schematic representation of a charging strategy provided in an embodiment of this application.

[0055] First, set multiple voltage thresholds Vmin, Vstart, Vcc, and Vmax, and multiple temperature thresholds t1, t2, and t3. Vmin is the minimum charging voltage threshold for the battery pack, Vstart is the normal charging voltage threshold, Vcc is the charging voltage threshold that meets the maximum charging current rate of the battery pack, Vmax is the maximum charging voltage threshold, t1 is the state temperature threshold, t2 is the high-temperature protection temperature threshold, and t3 is the maximum charging temperature threshold. Second, based on the characteristics and parameters of the battery pack, set multiple charging current values ​​CC1, CC2, and CC3. 3. CC4 and CC5, where CC1 corresponds to the voltage threshold range of Vmin to Vstart and the temperature threshold range of 0 to t3; CC2 corresponds to the voltage threshold range of Vstart to Vmax and the temperature threshold range of 0 to t1; CC3 corresponds to the voltage threshold range of Vstart to Vcc and the temperature threshold range of t1 to t3; CC4 corresponds to the voltage threshold range of Vcc to Vmax and the temperature threshold range of t1 to t2; CC5 corresponds to the voltage threshold range of Vcc to Vmax and the temperature threshold range of t2 to t3; and CC4 is the maximum charging current of the battery pack. In this embodiment, the above intermediate temperature threshold range is the temperature threshold range of t1 to t3. It is worth noting that the above values ​​are only used as examples to facilitate understanding of the charging current adjustment method proposed in this application; in actual applications, the current parameters are not limited to the above values.

[0056] Step S140: Send the target charging current value to the charging device so that the charging device adjusts the charging current according to the target charging current value.

[0057] It can be understood that the charging strategy under the current battery pack status is output, and the target charging current value obtained therefrom is sent to the charging device, so that the charging current is adjusted according to the target charging current value.

[0058] The adjustment methods also include:

[0059] The battery pack and / or charging device stores a preset reduction range for the intermediate temperature threshold, the maximum charging voltage threshold, and the charging current.

[0060] If the sampling voltage reaches the preset maximum charging voltage threshold and the sampling temperature is within the preset intermediate temperature threshold range, the current charging current will be reduced by a preset amount.

[0061] It is understood that the battery pack may store a preset reduction range of intermediate temperature threshold, maximum charging voltage threshold, and charging current, or the charging device may store a preset reduction range of intermediate temperature threshold, maximum charging voltage threshold, and charging current, or the battery pack and the charging device may each store one or both of the preset reduction ranges of the aforementioned intermediate temperature threshold, maximum charging voltage threshold, and charging current.

[0062] In one embodiment, after adjusting the charging current according to the target charging current value, the method further includes:

[0063] If the sampling temperature reaches the preset maximum charging temperature threshold, the charging device will stop outputting charging current.

[0064] In one embodiment, after adjusting the charging current according to the target charging current value, the method further includes:

[0065] If the sampling voltage reaches the preset maximum charging voltage threshold and the sampling temperature is not within the preset intermediate temperature threshold range, then the charging device will stop outputting charging current.

[0066] Continue reading Figure 2 When the battery pack temperature reaches t3, the battery pack is in an overheated state, so it is necessary to cut off the charging current supply immediately to avoid damage to the cells and other components caused by the overheating of the battery pack. Similarly, when the battery pack voltage reaches Vmax and the temperature is not between t1 and t3, the battery pack is in an overvoltage state, and it is also necessary to cut off the charging current supply immediately.

[0067] In one embodiment, after adjusting the charging current according to the target charging current value, the method further includes:

[0068] If the sampling voltage reaches the preset maximum charging voltage threshold and the sampling temperature is within the preset intermediate temperature threshold range, the current charging current will be reduced in a stepwise manner by a preset magnitude.

[0069] In one embodiment, after reducing the current charging current by a preset amount, the method further includes:

[0070] Maintain the reduced charging current until the sampled voltage reaches the maximum charging voltage threshold again.

[0071] In one embodiment, after the sampling voltage reaches the maximum charging voltage threshold again, the method further includes:

[0072] The process involves repeatedly reducing the current charging current by a preset amount and maintaining the reduced charging current until the sampled voltage reaches the maximum charging voltage threshold again, and until the charging current reaches the preset charging cutoff current.

[0073] In one embodiment, after the charging current reaches a preset charging cutoff current, the method further includes:

[0074] Once the battery pack is confirmed to be fully charged, the charging equipment is controlled to stop outputting charging current.

[0075] refer to Figure 3 and Figure 4 It is understandable that when the battery pack voltage reaches Vmax, the battery pack communicates with the charging equipment to reduce the charging current. As the charging current decreases, the battery pack voltage decreases. After maintaining the reduced charging current for a period of time, the battery pack voltage slowly rises back to Vmax (e.g., during the T1-T2 time period). Then, the charging current is reduced again, and the battery pack voltage decreases again. This process is repeated for multiple time periods until the current drops to a preset charging cutoff current (e.g., multiple time periods such as T2-T3, T3-T4, T4...TN).

[0076] Based on the same inventive concept as the foregoing embodiments, this application provides a charging current adjustment device, such as... Figure 5 As shown, it includes:

[0077] Voltage and temperature detection module 21 is used to acquire the sampled voltage and sampled temperature of the battery pack.

[0078] The threshold setting module 22 is used to divide multiple voltage threshold ranges and multiple temperature threshold ranges according to the parameters and characteristics of the battery pack, and set multiple charging current values, each charging current value corresponding to a voltage threshold range and a temperature threshold range.

[0079] The current value calculation module 23 is used to determine the voltage threshold range corresponding to the sampling voltage and the temperature threshold range corresponding to the sampling temperature, and then determine the charging current value corresponding to the sampling voltage and the sampling temperature as the target charging current value.

[0080] The charging current adjustment module 24 is used to send the target charging current value to the charging device so that the charging device adjusts the charging current according to the target charging current value.
