Detailed Implementation

[0057] 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 denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims. It should also be understood that the term “and / or” as used in this disclosure refers to and includes any or all possible combinations of one or more of the associated listed items.

[0058] With the development of charging technology, batteries in electronic devices can be charged quickly, improving charging speed. However, because the system load in electronic devices consumes a certain load current, when charging the battery with a defined charging current, the current flowing into the battery may be less than the charging current, affecting the charging speed. To eliminate the influence of the system load on battery charging, the output current of the charging circuit needs to exceed the charging current to compensate for the load current.

[0059] In related technologies, a charging method is provided, comprising: determining the charging current of the battery while the charging circuit is charging the battery; determining the load current consumed by the system load; and controlling the charging circuit to output a target current. The target current is the sum of the charging current and the load current. This method compensates for the load current by having the charging circuit output an additional load current, ensuring that the current flowing into the battery reaches the charging current. However, since the load current is the current consumed by the system load at the current moment, while the target current output by the charging circuit only changes at the next moment, the target current suffers from a lag problem. If the load current suddenly decreases at the next moment, the current flowing into the battery suddenly increases and exceeds the maximum allowable current (the current that causes lithium plating in the battery), leading to unreliable battery charging.

[0060] To address the aforementioned technical problems, this disclosure provides a charging method that controls the first compensation current input to the charging circuit by using a current compensation strategy determined based on the charging temperature and battery voltage. This prevents the current flowing into the battery from exceeding the maximum allowable current when the load current suddenly decreases, thereby improving the reliability of battery charging.

[0061] This disclosure provides a charging method, such as... Figure 1 As shown, the method includes:

[0062] S100: While the charging circuit is charging the battery, the charging temperature and the battery voltage are obtained.

[0063] S200: Determine the current compensation strategy based on the charging temperature and battery voltage.

[0064] S300: According to the current compensation strategy, control the first compensation current input to the charging circuit.

[0065] In this embodiment, when the charging circuit charges the battery, the system load in the electronic device consumes a certain load current, which needs to be compensated. Since charging temperature and battery voltage affect the battery charging current and thus the battery's lifespan, the charging temperature and battery voltage are obtained. Based on the charging temperature and battery voltage, a current compensation strategy is determined to match the charging current. According to the current compensation strategy, the first compensation current input to the charging circuit is controlled to compensate the load current. By determining the current compensation strategy based on the charging temperature and battery voltage, over-compensation is avoided when the load current changes, preventing the current flowing into the battery from exceeding the maximum allowable current, thereby improving the reliability of battery charging. Simultaneously, by controlling the input current of the charging circuit to compensate the load current, frequent adjustments to the output current of the charging circuit are avoided, preventing the current flowing into the battery from exceeding the maximum allowable current, further improving the reliability of battery charging.

[0066] For example, the charging circuit can be a DC-DC converter circuit or a charge pump circuit. The charging temperature can be the overall temperature of the electronic device or the temperature of the battery.

[0067] In one embodiment, such as Figure 2 As shown, the current compensation strategy determined in step S200 based on the charging temperature and battery voltage is determined in the following way:

[0068] S210. Determine the charging parameters used to set the battery charging current based on the charging temperature and battery voltage. The charging parameters are the charging temperature or the battery voltage.

[0069] S220. Determine the corresponding current compensation strategy based on the charging parameters.

[0070] In this embodiment, since charging temperature and battery voltage affect the battery charging current from different perspectives, and the charging current is determined by only one of them at any given time, the charging parameters used to set the charging current are determined based on the charging temperature and battery voltage. Because the charging current determined based on charging temperature or battery voltage has different effects on battery lifespan, a corresponding current compensation strategy is determined based on the charging parameters. By determining the corresponding current compensation strategy based on the charging parameters used to set the charging current, the current flowing into the battery after compensation with the first compensation current does not exceed the maximum allowable current, thereby improving the reliability of battery charging.

[0071] In one embodiment, such as Figure 3 As shown, the charging parameters used in step S210 to determine the battery charging current setting based on the charging temperature and battery voltage are determined in the following way:

[0072] S211. Determine the first charging current of the battery based on the charging temperature.

[0073] S212. Determine the second charging current of the battery based on the battery voltage.

[0074] S213. Determine the charging parameters based on the first charging current and the second charging current.

[0075] In this embodiment, since charging temperature affects battery lifespan and the user experience of electronic devices, a first charging current is determined based on the charging temperature. Since battery voltage reflects the degree of charging and affects lithium plating, a second charging current is determined based on the battery voltage. Charging parameters are determined based on the first and second charging currents to select a charging current that allows for safe and rapid charging of the battery. By determining the charging parameters based on the first and second charging currents determined by the charging temperature and battery voltage, respectively, the first compensation current can prevent the current flowing into the battery from exceeding the maximum allowable current while compensating for the load current, thereby improving the reliability of battery charging.

[0076] For example, such as Figure 4 As shown, the curve representing the change in the first charging current can be represented by curve S1, and the curve representing the change in the second charging current can be represented by curve S2. Here, the horizontal axis t represents time in minutes, and the vertical axis I represents current in amperes (A).

[0077] In one embodiment, the charging parameters in step S213, determined based on the first charging current and the second charging current, are determined in the following manner:

[0078] If the first charging current is less than the second charging current, the charging parameter is determined to be the charging temperature.

[0079] If the first charging current is greater than or equal to the second charging current, the charging parameter is determined to be the battery voltage.

[0080] In this embodiment, when the first charging current is less than the second charging current, the charging current is limited by the charging temperature and should not be increased; therefore, the charging temperature is determined as the charging parameter. When the first charging current is greater than or equal to the second charging current, the charging current is limited by the battery voltage and should not be increased; therefore, the battery voltage is determined as the charging parameter. By determining the charging parameters based on the magnitudes of the first and second charging currents, excessive charging current that could affect battery lifespan is avoided, thereby improving the reliability of battery charging.

[0081] In one embodiment, the determination of the corresponding current compensation strategy based on the charging parameters in step S220 is made in the following manner:

[0082] When the charging parameter is the charging temperature, the current compensation strategy is determined to be a second compensation current with the magnitude of the first current value output by the charging circuit.

[0083] Given the battery voltage as the charging parameter, the current compensation strategy is determined to be either to output a second compensation current with a second current value or to stop outputting the second compensation current.

[0084] The first current value is greater than the second current value. The first compensation current and the second compensation current are positively correlated.

[0085] In this embodiment, when the charging parameter is the charging temperature, a temporary increase in charging current will not cause lithium plating and has little impact on battery life. Therefore, the current compensation strategy is determined to be a larger second compensation current output by the charging circuit. When the charging parameter is the battery voltage, a temporary increase in charging current will cause lithium plating and significantly impact battery life. Therefore, the current compensation strategy is determined to be a smaller second compensation current output by the charging circuit or to stop outputting the second compensation current. Since the output current of the charging circuit needs time to adjust as the load current decreases, there is a risk of over-compensation. By making the first current value greater than the second current value, the battery life can be avoided while effectively compensating for the load current, thereby improving the reliability of battery charging.

[0086] For example, the first current value and the second current value can be preset current values. When the first current value is a preset current value, its range can be 50mA to 100mA. The first current value can be 60mA, 70mA, 80mA, etc. When the second current value is a preset current value, its range can be 800mA to 1000mA. The second current value can be 850mA, 900mA, 950mA, etc.

[0087] For example, when the current compensation strategy is that the charging circuit stops outputting the second compensation current, the second compensation current is zero and the first compensation current is zero.

[0088] For example, when the electronic device is powered on, if the charging parameter is the battery voltage, the current compensation strategy is determined to be a second compensation current with a second current value output by the charging circuit. When the electronic device is powered off, if the charging parameter is the battery voltage, the current compensation strategy is determined to stop outputting the second compensation current. This is because when the electronic device is powered on, the system load consumes a certain amount of load current, and load current compensation is performed using the second current value. When the electronic device is powered off, the system load consumes almost no load current, and no load current compensation is performed.

[0089] In one embodiment, the first current value is related to the load current consumed by the system load of the electronic device when the screen of the electronic device is off.

[0090] In this embodiment, since the system load consumes a high load current when the screen of the electronic device is on and a low load current when the screen is off, and the screen may switch between on and off states, by relating the first current value to the load current consumed by the system load when the screen is off, it is possible to prevent the current flowing into the battery from increasing rapidly when the screen changes from on to off, thus preventing lithium plating in the battery and improving the reliability of battery charging.

[0091] In one embodiment, the second current value is related to the load current consumed by the system load of the electronic device when the screen of the electronic device is lit.

[0092] In this embodiment, since the system load consumes a low load current when the screen of the electronic device is off and a high load current when the screen is on, and the screen may switch between off and on states, by relating the second current value to the load current consumed by the system load when the screen is on, the load current can be compensated as much as possible for fast charging when the screen is on, and lithium plating of the battery can be avoided when the screen is off, thereby improving the reliability of battery charging.

[0093] In one embodiment, before determining the corresponding current compensation strategy based on the charging parameters in step S220, determining the current compensation strategy based on the charging temperature and the battery voltage in step S200 further includes:

[0094] The first current value is determined based on the charging temperature and the battery voltage.

[0095] In this embodiment, since the second compensation current has a wide range of values ​​when the charging parameter is the charging temperature, and it does not cause lithium plating in the battery, a first current value is determined based on the charging temperature and the battery voltage to balance the charging speed and lifespan of the battery. By determining the first current value based on the charging temperature and the battery voltage, it is possible to avoid affecting the battery's lifespan while meeting the requirements for fast charging, thereby improving the reliability of battery charging.

[0096] For example, in the above steps, determining the first current value based on the charging temperature and the battery voltage can be achieved by averaging the first charging current determined based on the charging temperature and the second charging current determined based on the battery voltage. The difference between the average current and the charging current can be used as the first current value, or the product of the average current and a preset coefficient can be used as the first current value. The preset coefficient can range from 0 to 1.

[0097] In one embodiment, the first compensation current input to the charging circuit in step S300, according to the current compensation strategy, is determined in the following manner:

[0098] When the current compensation strategy is to output a second compensation current to the charging circuit, the first compensation current is determined based on the second compensation current and the operating mode of the charging circuit.

[0099] The first compensation current is input to the charging circuit.

[0100] When the current compensation strategy is that the charging circuit stops outputting the second compensation current, the input of the first compensation current to the charging circuit is stopped.

[0101] In this embodiment, the relationship between the current input to the charging circuit and the current output by the charging circuit differs depending on the operating mode of the charging circuit. When the current compensation strategy is to output a second compensation current, the second compensation current is converted according to the operating mode of the charging circuit to determine the first compensation current, which is then input to the charging circuit. When the current compensation strategy is to stop the charging circuit from outputting the second compensation current, there is no need to convert the second compensation current, and the first compensation current is stopped from being input to the charging circuit. By determining the second compensation current first and then the first compensation current for load current compensation, the load current can be accurately compensated while avoiding impact on battery life, thereby improving the reliability of battery charging.

[0102] For example, taking a charge pump circuit as the charging circuit, the determination of the first compensation current based on the second compensation current and the operating mode of the charging circuit in the above steps will be explained. When the charge pump circuit operates in a 2:1 operating mode, the first compensation current is determined to be half of the second compensation current. When the charge pump circuit operates in a 1:2 operating mode, the first compensation current is determined to be twice the second compensation current. When the charge pump circuit operates in a 4:1 operating mode, the first compensation current is determined to be one-quarter of the second compensation current. When the charge pump circuit operates in a 1:4 operating mode, the first compensation current is determined to be four times the second compensation current.

[0103] In one embodiment, such as Figure 5 As shown, after obtaining the charging temperature and battery voltage in step S100, the charging method further includes:

[0104] S400: Determine the battery charging current based on the charging temperature and battery voltage.

[0105] S410. Determine the target current input to the charging circuit based on the charging current and operating mode.

[0106] S420: Input the target current to the charging circuit.

[0107] In the case where the current compensation strategy is to output a second compensation current through the charging circuit, the input current of the charging circuit is the sum of the target current and the first compensation current.

[0108] In this embodiment, since charging temperature and battery voltage affect the battery charging current from different perspectives, the charging current is determined based on these factors. Because there is a relationship between the current input to the charging circuit and the current output by the charging circuit, a target current is determined based on the charging current and the operating mode, and this target current is input to the charging circuit. By inputting the sum of the target current and the first compensation current into the charging circuit, the charging circuit can output a charging current and a second compensation current to charge the battery and compensate for the load current, thereby improving the reliability of battery charging.

[0109] For example, determining the battery charging current based on the charging temperature and battery voltage in step S400 may include steps S211 to S213, and determining the battery charging current based on charging parameters.

[0110] For example, the charging current of the battery in the above steps is determined according to the charging parameters in the following way:

[0111] If the first charging current is less than the second charging current, the charging current is determined to be the first charging current.

[0112] If the first charging current is greater than or equal to the second charging current, the charging current is determined to be the second charging current.

[0113] This disclosure provides a charging method, such as... Figure 6 As shown, the method includes:

[0114] S500: When the charging circuit is charging the battery, the charging temperature and the battery voltage are obtained.

[0115] S510. Determine the first charging current of the battery based on the charging temperature.

[0116] S520. Determine the second charging current of the battery based on the battery voltage.

[0117] S530: When the first charging current is less than the second charging current, the charging parameter is determined to be the charging temperature.

[0118] S540, Determine the current compensation strategy as a second compensation current with the output value of the first current value of the charging circuit.

[0119] S550, Determine the charging current as the first charging current.

[0120] S560. If the first charging current is greater than or equal to the second charging current, the charging parameter is determined to be the battery voltage.

[0121] S570, The current compensation strategy is determined to be a second compensation current with the output value of the second current of the charging circuit.

[0122] S580, Determine the charging current as the second charging current.

[0123] S590. Determine the first compensation current based on the second compensation current and the operating mode of the charging circuit.

[0124] S600, Input the first compensation current to the charging circuit.

[0125] S610. Determine the target current input to the charging circuit based on the charging current and operating mode.

[0126] S620: Input the target current to the charging circuit.

[0127] In this embodiment, when the charging circuit charges the battery, the charging temperature and battery voltage are acquired to determine charging parameters that limit the charging current. Since the charging temperature affects the charging current, a first charging current is determined based on the charging temperature. Since the battery voltage affects the charging current, a second charging current is determined based on the battery voltage. When the first charging current is less than the second charging current, using the first charging current results in a higher charging temperature, affecting battery lifespan; therefore, the charging parameter is determined to be the charging temperature. The current compensation strategy is determined to be a second compensation current output by the charging circuit equal to the first current value. Using a larger first current value for current compensation prevents lithium plating caused by load current changes when the battery can be charged quickly. Alternatively, the charging current is determined to be the first charging current, and the battery is charged with a smaller first charging current to reduce the impact of charging temperature on battery lifespan. When the first charging current is greater than or equal to the second charging current, using the second charging current may cause lithium plating; therefore, the charging parameter is determined to be the battery voltage. The current compensation strategy is determined to be a second compensation current output by the charging circuit equal to the second current value. Using a smaller second current value for current compensation avoids lithium plating caused by load current changes. Since the operating mode of the charging circuit determines the relationship between the current input to the charging circuit and the current output by the charging circuit, a first compensation current is determined based on the second compensation current and the operating mode, and this first compensation current is input to the charging circuit. A target current is determined based on the charging current and the operating mode, and this target current is input to the charging circuit. By determining the current compensation strategy based on the charging temperature and the battery voltage, over-compensation is avoided when the load current changes, preventing the current flowing into the battery from exceeding the maximum allowable current, thereby improving the reliability of battery charging. Simultaneously, by controlling the input current of the charging circuit to compensate for the load current, frequent adjustments to the output current of the charging circuit are avoided, preventing the current flowing into the battery from exceeding the maximum allowable current, further improving the reliability of battery charging.
