[0042] Embodiment 1

[0043] Figure 1 A flowchart of a charger charging management method is provided for the first embodiment of the present invention. This embodiment is applicable to the charging of multiple battery packs, etc. The method can be executed by a charger charging management device, which can be implemented in the form of hardware and / or software. The device can be configured in power tools, garden tools, outdoor products, toy products, energy storage, electric vehicle charging systems, consumer electronic products, etc. Figure 1 As shown, the method includes:

[0044] S101, obtaining the charging current, charging voltage and charging time of the battery pack after charging starts.

[0045] Among them, the battery pack can be a battery pack with a capacity of 10Ah or above, that is, a large-capacity battery pack. Due to the large capacity, the power demand during charging is relatively high, and the charger needs to be able to provide sufficient current and voltage. It is necessary to manage the temperature and power during the charging process to ensure safe charging. When the charger detects that the battery pack is connected, it will start the charging process, monitor and obtain the key charging parameters in real time, including but not limited to the charging current, charging voltage and charging time. The charging current refers to the current value actually output during charging. The charging voltage refers to the voltage value applied to the battery pack by the charger or the voltage value fed back to the charger by the battery pack through communication. The charging time refers to the duration of the current charging process. Specifically, the charging current and charging voltage can be obtained through sensors, or the charging time can be obtained by a timer.

[0046] S102: Determine charging power according to charging current and charging voltage.

[0047] Among them, the charging power can be calculated based on the obtained charging current and charging voltage. Different electronic devices or batteries require different charging voltages and currents. For example, mobile phone batteries usually require a voltage of about 5V and a current of 1A-3A, while some large-capacity battery packs may require higher voltages and larger currents. By adjusting the charging voltage and charging current, the charging needs of different devices can be met while ensuring the safety and efficiency of the charging process. Determining the charging power by charging current and charging voltage can help us better understand and control the charging process and ensure the safety and efficiency of charging.

[0048] S103: Predict charging temperature rise according to charging power.

[0049] Among them, the charging temperature rise can be predicted based on the charging power and the thermal resistance parameters of the power devices inside the charger. The power devices of the charger refer to the core components in the charger that are responsible for processing electrical energy, such as transformers, power tubes, rectifier diodes, etc. These devices will generate heat when working at high power, and temperature is an important factor in their performance and life. The thermal resistance parameter is a physical quantity that describes the ability of the power devices inside the charger to transfer heat from the internal heat source to the external environment, usually expressed as the temperature rise caused by unit power.

[0050] S104: Acquire the temperature of the power device inside the charger, and determine the charging temperature according to the charging temperature rise and the temperature of the power device.

[0051] Among them, the temperature sensor can be used to detect the temperature of power devices such as transformers, power tubes, and rectifier diodes in real time. The charging temperature rise can be predicted based on the charging power and the thermal resistance parameters of the power devices inside the charger. The charging temperature can be determined based on the charging temperature rise and the temperature of the power devices. The charger can then determine whether it is necessary to adjust the charging strategy to ensure the safety of the equipment.

[0052] S105: The charger adjusts the charging current according to the relationship between the charging temperature and the preset temperature.

[0053] If the charging temperature is higher than the preset temperature, the charger will dynamically adjust the charging current to control the temperature rise, ensure charging safety and battery protection. Specifically, when the charging temperature approaches or reaches the preset temperature, the charger can automatically reduce the charging current and reduce the heat generated by the power device, thereby controlling the temperature rise and ensuring that the charger always operates within a safe temperature range.

[0054] The technical solution of the embodiment of the present invention is that after the charger is connected to the battery pack, the charging current, charging voltage and charging time are monitored in real time, and the charging power is calculated based on the charging current and charging voltage to evaluate the energy input of the charging process. The charger predicts the charging temperature rise during the charging process based on the charging power and the thermal resistance parameters of the power device, obtains the temperature of the power device inside the charger, and determines the charging temperature based on the charging temperature rise and the temperature of the power device, and adjusts the charging current based on the charging temperature and the preset temperature to achieve adaptive control of the charging process, and ensures the safe operation of the battery and charger by dynamically adjusting the charging current, reduces the negative impact of high temperature on battery performance and life, and optimizes the charging process. The intelligent and adaptive control of the charger is realized to improve the user experience.

[0055] In some optional embodiments of the present invention, determining the charging power according to the charging current and the charging voltage includes:

[0056] The charging power is calculated based on the product of the charging current and the charging voltage.

[0057] Among them, by measuring the charging current and charging voltage in real time, the charging power is calculated by the product of the charging current and charging voltage. The charging power can monitor the energy transfer rate during the charging process in real time, providing a basis for evaluating the working status of the battery and charger.

[0058] Embodiment 2

[0059] Figure 2 This is a flowchart of another charger charging management method provided in Embodiment 2 of the present invention. In some optional embodiments of the present invention, refer to Figure 1 and Figure 2 After further refining S103, predicting the charging temperature rise according to the charging power, the method includes:

[0060] S201, obtaining the charging current, charging voltage and charging time after the battery pack starts charging.

[0061] S202: Determine charging power according to charging current and charging voltage.

[0062] S203: predict charging temperature rise according to charging power and thermal resistance parameters of power devices of the charger.

[0063] The thermal resistance parameter of the power device represents the heat dissipation capability of the device and can represent the temperature rise caused by each watt of power. The charging temperature rise can be predicted based on the product of the charging power and the thermal resistance parameter of the power device, thereby determining the charging temperature.

[0064] S204: Acquire the temperature of the power device inside the charger, and determine the charging temperature according to the charging temperature rise and the temperature of the power device.

[0065] Among them, a temperature sensor can be used to detect the temperature of the power device, and the charging temperature can be determined according to the sum of the charging temperature rise and the temperature of the power device. Specifically, in the charger, different power devices such as transformers and power tubes share the charging power, and the actual power distribution ratio can be determined by design parameters or measurements. For example, the transformer may share 60% of the total power, the power tube shares 30%, and the rectifier diode shares 10%. According to the ratio, the power of each power device can be calculated separately. For each power device, the charging temperature rise is calculated according to the product of its thermal resistance parameter and the shared power, and the charging temperature is determined by the sum of the charging temperature rise and the temperature of the power device, and the charging temperature is compared with the preset temperature. If the charging temperature is close to or exceeds the preset temperature, the temperature can be reduced by reducing the power or current. If the charging temperature is within a safe range, it is allowed to maintain the current charging current, or increase the power when conditions permit.

[0066] S205: The charger adjusts the charging current according to the relationship between the charging temperature and the preset temperature.

[0067] The technical solution of the embodiment of the present invention calculates the charging power through the real-time charging current and charging voltage, and calculates the charging temperature rise according to the charging power and the thermal resistance parameters of the charger power device. The charger can predict the charging temperature and adjust the charging current in time according to the predicted charging temperature and the preset temperature, thereby preventing overheating. It can avoid safety risks such as equipment damage and fire caused by excessive temperature, ensure that the charger operates within a safe temperature range, and optimize the charger performance.

[0068] In some optional embodiments of the present invention, obtaining the temperature of a power device inside the charger includes:

[0069] The temperature of the space and components inside the charger is detected by a temperature sensor as the temperature of the power device.

[0070] Among them, the temperature of the space inside the charger refers to the temperature inside the charger. Since the charger generates heat during operation, the internal temperature can reflect the overall thermal environment of the charger. The temperature of the components refers to the surface temperature of each electronic component inside the charger. Components such as power devices, capacitors, inductors, etc. will generate heat during operation, and their temperature will directly affect their performance and life. Specifically, multiple temperature sensors can be installed inside the charger to detect the temperature of the space inside the charger and the temperature of key components, respectively, to ensure that the power devices operate within a safe temperature range.

[0071] Embodiment 3

[0072] Figure 3 This is a flowchart of another charger charging management method provided in Embodiment 3 of the present invention. In some optional embodiments of the present invention, refer to Figure 1 and Figure 3 After further refining S105, adjusting the charging current according to the relationship between the charging temperature and the preset temperature, the method includes:

[0073] S301, obtaining the charging current, charging voltage and charging time of the battery pack after charging starts.

[0074] S302: Determine charging power according to charging current and charging voltage.

[0075] S303: Predict charging temperature rise according to charging power.

[0076] S304: Acquire the temperature of the power device inside the charger, and determine the charging temperature according to the charging temperature rise and the temperature of the power device.

[0077] S305 . When the charging temperature reaches a first preset temperature, reduce the charging current.

[0078] The first preset temperature refers to a preset high temperature threshold, which can be the upper limit of the safe temperature of the charger. When the predicted charging temperature reaches or exceeds the first preset temperature, it means that the temperature of the power device or the internal space of the charger begins to rise to a higher level. The charger can reduce the heat generated by the power device by reducing the charging current, ensuring that the charging process remains within a safe temperature range, thereby preventing the temperature from continuing to rise and ensuring system safety.

[0079] The technical solution of the embodiment of the present invention can not only prevent the charger from overheating and protect key components by reducing the charging current to control the temperature rise, but also improve the safety of the charger, extend the life of the device and enhance the user experience, while ensuring the stability and safety of the charging process.

[0080] In some optional embodiments of the present invention, when the charging temperature reaches the first preset temperature, after reducing the charging current, the method further includes:

[0081] When the charging temperature reaches a second preset temperature, the charging current is increased; wherein the second preset temperature is lower than the first preset temperature

[0082] Among them, the second preset temperature refers to the preset low temperature threshold, which indicates the lower limit of the safe temperature of the charger. If the predicted charging temperature drops to the second preset temperature, the charger can increase the charging current, improve the charging efficiency, and shorten the charging time to meet the user's fast charging needs while ensuring that the temperature remains within a controllable range. When the charging temperature drops to the second preset temperature, increasing the charging current helps to increase the charging speed and reduce the charging time. By dynamically adjusting the charging current, the charger can adjust the charging strategy in real time according to the predicted charging temperature and charging power to maintain a balance in the charging process. Users can complete charging in a shorter time, which improves the overall charging experience, especially when fast charging is required.

[0083] Some optional embodiments of the present invention further include:

[0084] When the accumulated charging time reaches a preset time, the charging current is reduced.

[0085] Among them, the accumulation of charging time refers to the total charging time from the start of charging to the current moment. It can be recorded by the timer inside the charger. The preset time refers to a time threshold predefined in the design or software settings of the charger. When the charging time reaches this preset value, the charger can reduce the charging current. For example, assume that the preset time of a charger is 3 hours. At the beginning of charging, the charger charges the battery pack with a current of 10A. When the cumulative charging time reaches 3 hours, the charger can automatically reduce the charging current to a preset value, such as 5A, according to the type of battery pack. It can ensure that the battery is charged in a safer and more stable manner in the later stages of charging, avoiding battery overheating or overcharging problems caused by high current charging.
