[0036] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0037] The charging method provided by the embodiments of the present disclosure can be applied to the application scenario of terminal charging, for example, it can be applied to the scenario of charging a battery in a terminal equipped with a battery to realize charging of the terminal.

[0038] In the related art, the charging method is usually implemented through a combination of software and hardware, and the charging scheme is fixed in advance. However, this fixed charging method does not change with changes in the environment and scene, and it is difficult to dynamically adjust according to the user's special scene and needs. For example, it is impossible to control the charging time according to the user's needs.

[0039] In view of this, an embodiment of the present disclosure provides a charging method. In the charging method provided by the present disclosure, a user sets a charging time, and charging is performed based on the charging time set by the user.

[0040] For the convenience of description in the embodiment of the present disclosure, the charging time set by the user is referred to as the first charging time.

[0041] Figure 1 The figure is a flow chart of a charging method according to an exemplary embodiment.

[0042] In step S11 , a first charging time is determined, where the first charging time is the time set by the user for charging the battery from the current battery capacity to the target battery capacity.

[0043] The first charging time generally refers to the charging time set by the user. On the one hand, the first charging time can be set by the user in real time at the beginning of charging or during the charging process. On the other hand, the first charging time can also be set by the user in advance and saved in the terminal for direct use later. For example, it can be the charging time set by the user during a certain charging process, and the set charging time can be used as the first charging time for subsequent charging.

[0044] The target battery capacity may be set by the user or may be a fixed default value. In one implementation, the target battery capacity is the fully charged capacity of the battery.

[0045] In step S12, a charging current for charging the battery is determined according to the first charging time and the target battery capacity.

[0046] In step S13, the battery is charged based on the determined charging current.

[0047] The charging method provided in the embodiment of the present disclosure determines the charging current for charging the battery according to the first charging time set by the user and the target battery capacity. The battery is charged based on the determined charging current, and charging control can be implemented based on the charging time set by the user, thereby meeting the user's needs for adjusting and controlling the charging time, and further, the charging can be adjusted based on different application scenarios and usage requirements during the charging process, thereby improving the user experience.

[0048] The present disclosure embodiment describes the charging method involved in the above embodiment below.

[0049] In one embodiment, the battery has different charging strategies involved in the charging process, and different charging stages require different charging currents. Therefore, in the embodiment of the present disclosure, different determination methods are used based on the charging currents required at different charging stages.

[0050] In one example, the present disclosure embodiment uses the charging strategy including dividing the charging process into a constant current charging stage (CC charging stage) and a constant voltage charging stage (CV charging stage) during fast charging as an example to illustrate.

[0051] In one embodiment, if Figure 2 As shown, under normal circumstances, battery charging can be divided into two stages: CC charging stage and CV charging stage. Among them, CC charging stage and CV charging stage are generally distinguished by voltage. Figure 2 As shown, V1 is the voltage threshold for dividing the CC charging stage and the CV charging stage. When the voltage is less than V1, the charging is in the CC stage, and when the voltage is greater than or equal to V1, the charging is in the CV stage.

[0052] In the constant current charging stage, the charger provides a constant current to gradually increase the battery voltage. In this stage, the battery can accept a larger charging current and the battery charges faster. When the battery voltage gradually approaches the preset charging voltage, the charger will switch to the constant voltage charging stage.

[0053] In the constant voltage charging stage, the charger will maintain a constant charging voltage, while the current will gradually decrease. In this stage, the battery voltage remains stable, the chemical reaction inside the battery is gradually completed, and the battery is gradually filled. When the charging current drops to the preset cut-off current, the charging process ends.

[0054] For each specific type of battery, there is a corresponding specification. At different stages of battery charging, the charging current has an upper limit, which is the maximum charging current of the battery specification. The shortest charging time of the battery specification is the time it takes to charge the battery to the target battery capacity using the maximum charging current of the battery specification as the charging current. And during the charging process, the constant voltage charging stage is relatively fixed. For example, in the CV charging stage, from a specific battery capacity C 1 Charge to battery capacity C 2 The shortest charging time is fixed. Among them, the shortest charging time T in the CV charging stage cv And the battery capacity satisfies the following equation: T cv =f1(C 2 -C 1). Wherein, f1 is a function representing the mapping relationship between the charging battery capacity and the shortest charging time in the CV charging stage, and the mapping relationship function of each specific model of battery is fixed.

[0055] Based on this, in order to enable the user to set the time to charge the battery to a specified battery capacity during the constant voltage charging stage, a specific battery capacity C can be set during the constant voltage stage. 1 First, charge the battery from its current capacity C 0 Charge to a specific battery capacity C 1 , and then charge at a constant voltage during the second charging time from the current specific battery capacity C 1 Charge to target battery capacity C 2 .

[0056] In view of this, an embodiment of the present disclosure provides a charging method. In the charging method provided by the present disclosure, a charging current for charging a battery is determined based on a first charging time and a second charging time.

[0057] Figure 3 The invention is a flowchart showing a method for determining a charging current for charging a battery according to a first charging time, a second charging time and a target battery capacity according to an exemplary embodiment.

[0058] In step S21 , the current charging stage of the battery is determined.

[0059] The charging stage includes a constant voltage charging stage or a constant current charging stage.

[0060] In step S22, a second charging time of the current charging stage of the battery is determined.

[0061] In step S23, a charging current for charging the battery is determined based on the first charging time, the second charging time, and the target battery capacity.

[0062] The second charging time of the current charging stage is the shortest charging time from the current battery capacity to the target battery capacity. The first charging time is the time set by the user for charging the battery from the current battery capacity to the target battery capacity.

[0063] The charging method provided by the embodiment of the present disclosure can determine the charging current according to the different stages of the charging process and the charging time set by the user, the shortest charging time of the battery specification and the target battery capacity, and use the determined charging current as the battery charging current to charge the battery, thereby improving the user's charging experience.

[0064] In view of the different magnitude relationships between the first charging time and the second charging time, the method for determining the charging current is also different, and the present disclosure provides a charging method. In the charging method provided by the present disclosure, the charging current for charging the battery is determined based on the first charging time, the second charging time and the target battery capacity.

[0065] Figure 4 The invention is a flowchart showing a method for determining a charging current for charging a battery according to a first charging time, a second charging time and a target battery capacity according to an exemplary embodiment.

[0066] In step S31, it is determined whether the first charging time is greater than the second charging time.

[0067] In step S32, if the first charging time is greater than the second charging time, a first charging current is determined, and the first charging current is used as the charging current for charging the battery.

[0068] In step S33, if the first charging time is less than the second charging time, the second charging current is determined to be the charging current for charging the battery.

[0069] The second charging current is a charging current sufficient to charge the battery to a target charging capacity within a second charging time.

[0070] If the first charging time is greater than the second charging time, the charging current for charging the battery is determined according to the charging time set by the user and the target battery capacity, and the battery is charged using this current as the charging current of the battery, and the battery is charged to the target battery capacity within the first charging time. If the first charging time is less than the second charging time, the battery is charged with the maximum charging current of the battery specification, and the battery is charged to the target battery capacity within the second charging time.

[0071] In the disclosed embodiment, the maximum charging current in the constant current charging and constant voltage charging stages has an upper limit. When the charging current exceeds the maximum charging current of the battery specification, the battery charging temperature will also increase significantly, which poses a great safety hazard. The method provided in the disclosed embodiment can not only realize charging control based on the charging time set by the user, thereby meeting the user's needs for adjusting and controlling the charging time, but also fully considers charging safety, and improves the user's charging experience while ensuring charging safety.

[0072] Figure 5 is a flowchart of a method for determining a first charging current according to an exemplary embodiment.

[0073] In step S41, based on the current charging stage of the battery, the capacity of the battery to be charged for constant current charging of the battery is determined.

[0074] In step S42, a first charging current is determined based on the capacity of the battery to be charged and the third charging time.

[0075] The third charging time is the difference between the first charging time and the second charging time.

[0076] In the embodiment of the present disclosure, the battery is charged to the target battery capacity at the time set by the user mainly by controlling the charging current of the constant current charging. The third charging time is the charging time set by the user minus the shortest charging time from the current battery capacity to the target battery capacity in the specification, that is, the constant current charging time. When the battery is in the constant current charging stage, the third charging time T cc1 =T 设 -T cv0 Among them, T 设 The charging time set by the user to charge the battery to the target battery capacity, T cv0 It is the full constant voltage charging time to charge the battery capacity to the target battery capacity after the constant current charging is completed. It is also fixed for a specific type of battery. When the battery is in the constant voltage charging stage, the third charging time T cc2 =T 设 -f1(C 2 -C 1 ). Among them, T 设 The charging time set by the user to charge the battery to the target battery capacity. 2 -C 1 ) is the time taken to charge the battery from the specified capacity to the target capacity during the constant voltage charging phase.

[0077] In one embodiment, determining a charging current for charging the battery based on the first charging time, the second charging time, and the target battery capacity includes:

[0078] If the battery is currently in the constant current charging stage, the target battery capacity is subtracted from the current battery capacity to obtain the differential capacity, and the differential capacity and the charging capacity of the battery in the constant voltage charging stage are used as the battery capacity to be charged for constant current charging of the battery.

[0079] Figure 6 The present invention is a flow chart showing a method for determining the capacity of a battery to be charged during constant current charging of a battery according to an exemplary embodiment.

[0080] In step S51, it is determined that the current charging stage of the battery is a constant current charging stage.

[0081] In step S52, the target battery capacity is subtracted from the current battery capacity to obtain a differential capacity.

[0082] In step S53, the difference capacity between the difference capacity and the charging capacity of the battery in the constant voltage charging stage is used as the battery capacity to be charged for constant current charging of the battery.

[0083] In the embodiment of the present disclosure, when the current charging stage of the battery is the constant current charging stage, the charging capacity C of the constant current charging stage is cc1 =CC 0 -C cv Where C is the target battery capacity set by the user, C 0 is the current capacity of the battery, C cv It is the battery capacity for constant voltage charging after the constant current charging stage. After determining the capacity of the battery to be charged in the constant current charging stage, the constant current charging current can be determined by the capacity of the battery to be charged and the constant current charging time, thereby realizing charging control based on the charging time set by the user. The constant current charging current I cc1 =C cc1 / T cc1 Among them, C cc1 is the charging capacity during the constant current charging phase, T cc1 It is the third charging time of the constant current charging stage.

[0084] In one embodiment, determining a charging current for charging the battery based on the first charging time, the second charging time, and the target battery capacity includes:

[0085] If the current charging stage of the battery is the constant voltage charging stage, the difference between the target battery capacity of constant current charging and the current battery capacity is used as the battery capacity to be charged for constant current charging of the battery, and the target battery capacity of constant current charging is a predefined battery capacity.

[0086] Figure 7 The present invention is a flow chart showing a method for determining the capacity of a battery to be charged during constant current charging of the battery in a constant voltage charging stage according to an exemplary embodiment.

[0087] In step S61, it is determined that the current charging stage of the battery is a constant voltage charging stage.

[0088] In step S62, the difference between the target battery capacity of constant current charging and the current battery capacity is used as the battery capacity to be charged for constant current charging of the battery.

[0089] In the embodiment of the present disclosure, when in the constant voltage charging stage, the current battery capacity C 0The second charging time to the target battery capacity C is fixed. We can further subdivide the constant voltage charging stage into constant current charging and constant voltage charging stages under the original constant voltage charging stage, and control the charging current of the constant current charging to charge the battery to the target battery capacity within the charging time set by the user.

[0090] Constant current charging capacity C during constant voltage charging stage cc2 =C 1 -C 0 , where C 0 is the current capacity of the battery, which is charged to C by constant current 1 , C 1 The battery capacity can be predefined, and then constant voltage charging is performed until the target battery capacity is reached. The constant current charging current I cc2 =C cc2 / T cc2 Among them, C cc2 is the constant current charging capacity in the constant voltage charging stage, T cc2 It is the third charging time of the constant voltage charging stage.

[0091] Figure 8 The invention is a flow chart showing a method for charging a battery based on a first charging current according to an exemplary embodiment.

[0092] In step S71 , constant current charging is performed based on the first charging current during the third charging time.

[0093] In step S72, in response to the charging time reaching the third charging time, switching to constant voltage charging is performed until the battery capacity reaches the target battery capacity.

[0094] In the embodiment of the present disclosure, the third charging time is the constant current charging time. In order to charge the battery to the target battery capacity at the time set by the user, the first charging current is first calculated according to the third charging time and the charging capacity of the current charging stage of the battery and the first charging current is used as the charging current for constant current charging. When the charging time reaches the third charging time, it is switched to constant voltage charging until the battery capacity is charged to the target battery capacity.

[0095] In one embodiment, performing constant current charging based on a determined charging current within a determined charging time includes:

[0096] Based on multiple charging currents and multiple charging times, multiple constant current charging is performed;

[0097] The sum of the multiple charging currents is the determined charging current, and the sum of the multiple charging times is the determined charging time.

[0098] In the embodiment of the present disclosure, a multi-segment current method can also be used in the constant current charging stage.1 Charging T 1 Time, I 2 Charging T 2 Time, I n Charging T n Time only needs to satisfy the following relationship:

[0099] T cc1 =T 1 +T 2 +…+T n

[0100] C cc1 =I 1 *T 1 +I 2 *T 2 +…I n *T n

[0101] In the constant voltage charging stage, constant current charging can also adopt a multi-stage current method, I 1 Charging T 1 Time, I 2 Charging T 2 Time, I n Charging T n Time only needs to satisfy the following relationship:

[0102] T cc2 =T 1 +T 2 +…+T n

[0103] C cc2 =I 1 *T 1 +I 2 *T 2 +…I n *T n

[0104] The above-mentioned multi-stage charging current and multi-stage charging time are charging currents and charging times that meet the battery charging specifications. The number of multi-stage charging stages and the specific charging current and charging time for each stage can be set according to different charging stages and requirements.

[0105] The charging method provided in the embodiment of the present disclosure can further set multiple currents and multiple time periods in the constant current charging stage and the constant voltage charging stage, making the charging more flexible and meeting the needs of different application scenarios.

[0106] In one embodiment, when the battery is in a charging state, the user customizes and sets a first charging time in real time at the beginning of charging or during charging, and determines the charging current according to the first charging time and the current charging stage. The constant current charging stage and the constant voltage charging stage are generally distinguished by voltage. When the voltage is less than V1, the charging is in the constant current charging stage, and when the voltage is greater than V1, the charging is in the constant voltage charging stage.

[0107] When in the constant current charging stage, the user sets the charging time T from the current battery capacity to the target battery capacity. 设 It is the sum of the charging time of the constant current charging stage and the charging time of the constant voltage charging stage. The second charging time, i.e. the shortest constant voltage charging time, is fixed for a specific type of battery and can be recorded as T cv0 According to the first charging time and the second charging time, the constant current charging time in the constant current charging stage can be determined as: T cc1 =T 设 -T cv0 The constant current charging battery capacity during the constant current charging phase is: C cc1 =CC 0 -C cv Where C is the target battery capacity set by the user, C 0 is the current capacity of the battery, C cv It is the battery capacity of the battery that is charged at constant voltage after the constant current charging stage. The first charging current in the constant current charging stage is the constant current charging current: I cc1 =C cc1 / T cc1 .

[0108] Determine the charging current in the constant current charging stage and set the charging current in the constant current charging stage to the determined current I cc1 , it can be achieved in the first charging time, that is, T 设 Charge the battery from the current battery capacity to the target battery capacity within the specified time.

[0109] When in the constant voltage charging stage, the second charging time, that is, the fastest charging time and battery capacity satisfy the following equation: T cv =f1(CC 0 ). Where T cv It is the constant voltage charging stage from the current battery capacity C 0 The shortest charging time to charge to the target battery capacity C is set during the constant voltage charging stage. 设 Less than or equal to T cv At this time, only the second charging current, i.e. the maximum charging current in the specification, can be used during the second charging time T cv When charging to the target battery capacity, set the charging time T in the constant voltage charging stage. 设 Greater than Tcv When the charging current is determined according to the target battery capacity, the method is as follows:

[0110] Charging capacity C during constant voltage charging cv =CC 0 -C 1 , where C is the target battery capacity set by the user, C 0 is the current capacity of the battery, which is charged to C by constant current 1 , C 1 The battery capacity can be predefined, and then constant voltage charging is performed until the target battery capacity is reached. The first charging current in the constant voltage charging stage is the constant current charging current I cc2 =C cc2 / T cc2 .

[0111] Determine the charging current in the constant voltage charging stage and set the charging current in the constant voltage charging stage to the determined current I cc2 , you can achieve T 设 Charge the battery from the current battery capacity to the target battery capacity within the specified time.

[0112] In the embodiment of the present disclosure, the charging current for charging the battery is determined according to the time set by the user for charging the battery from the current battery capacity to the target battery capacity, the target battery capacity, and the charging stage the battery is currently in. Under the premise of not exceeding the battery charging specification and ensuring charging safety, the charging method provided in the embodiment of the present disclosure realizes charging control based on the charging time set by the user, thereby meeting the user's needs for adjusting and controlling the charging time, and further, the charging can be adjusted based on different application scenarios and usage requirements during the charging process, thereby improving the user experience.

[0113] Based on the same concept, an embodiment of the present disclosure also provides a charging device.

[0114] It is understandable that in order to realize the above functions, the charging device provided in the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software.
