Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application provides a control method, a control device, electronic equipment and a medium.
The control method provided by the embodiment of the application can be applied to various application scenarios, and the embodiment of the application provides, but is not limited to, the following two application scenarios.
In a first application scenario, referring to the internal structure of the battery shown in fig. 1a, the battery may at least include: the battery cell 11 and the protection circuit 12, where the protection circuit 12 may include a first controller 121; the protection circuit 12 may protect the battery cell 11, for example, optionally, the protection circuit 12 may perform overcurrent protection, overvoltage protection, overheat protection, no-load protection, short-circuit protection, and the like on the battery cell 11.
In an alternative embodiment, the control method provided by the present application may be applied to the first controller 121 shown in fig. 1, and the first controller 121 may control the battery to implement the switching of the operation mode.
In a second application scenario, the control method provided by the present application may be applied to a second controller 13 in a terminal device corresponding to a battery, and the second controller 13 may control the battery to implement switching of a working mode. Wherein the battery is used for supplying power to the terminal equipment.
Fig. 1b is a structural diagram of an implementation manner of the terminal device provided in the present application.
The terminal device 10 includes at least: and a second controller 13, a battery 14 is used for supplying power to the terminal equipment.
The terminal device may be, for example, a desktop, a mobile terminal (e.g., a smartphone), an ipad, or the like.
The electronic device mentioned in the embodiment of the present application may be a battery mentioned in a first application scenario, and may also be a terminal device mentioned in a second application scenario.
It can be understood that the greater the full charge voltage corresponding to the battery cell, the greater the full capacity of the battery cell (the full capacity refers to the capacity of the battery cell when the voltage across the battery cell is the full charge voltage); in the embodiment of the present application, the maximum value of the voltages that can be applied to the two ends of the battery cell in different operation modes is referred to as a full charge voltage. The voltage at the two ends of the battery cell and the electric quantity of the battery cell complement each other, that is, the voltage at the two ends of the battery cell is higher at a certain moment, the capacity of the battery cell at the moment is inevitably higher, and vice versa.
For example, a battery may have a plurality of operation modes, and then for any one of the plurality of operation modes, a preset maximum voltage applied to a cell of the battery may be defined as a full charge voltage, for example, assuming that the battery has three operation modes, that is: in the working mode 1, the working mode 2, and the working mode 3, then for the working mode 1, the preset voltage range applied to the battery cell of the battery may be [0V,4V ], and then the full charge voltage corresponding to the working mode 1 is 4V; for the working mode 2, the preset voltage range applied to the battery cell of the battery may be [0V,4.2V ], and then the full charge voltage corresponding to the working mode 2 is 4.2V; for the operation mode 3, the preset voltage range applied to the battery cell may be [0V,4.45V ], and then the full charge voltage corresponding to the operation mode 3 is 4.45V.
In the embodiment of the application, a state that the voltage of the battery cell at two ends of the battery cell is greater than or equal to a threshold 1 and the capacity of the battery cell is greater than or equal to a threshold 2 is referred to as a high-voltage full-capacity state; the voltage at the two ends of the battery cell corresponds to the capacity of the battery cell; a state in which the cell is at a voltage across it that is greater than or equal to the threshold value 1 may be referred to as a high-voltage full-capacity state, or a state in which the cell is at a capacity that is greater than or equal to the threshold value 2 may be referred to as a high-voltage full-capacity state.
It can be understood that the larger the full charge voltage corresponding to the battery cell is, the longer the time that the battery cell of the battery is in a high-voltage full-capacity state may be, thereby causing the life of the battery cell to be shortened, but the larger the full charge voltage is, the longer the battery life may be increased; if the full charge voltage corresponding to the battery cell is smaller and the corresponding full capacity is smaller, the time that the battery cell of the battery is in the high-voltage full capacity state may be shorter, so that the service life of the battery cell of the battery is prolonged, and the service life of the battery is prolonged.
Therefore, in an alternative embodiment, the battery may have a plurality of operation modes, the full charge voltage applied to the battery cell in different operation modes is different, and the battery may be switched to different operation modes based on the acquired battery usage parameters.
In summary, the control method provided by the application controls the battery to switch to the corresponding working mode based on the battery use parameter, thereby achieving the purpose of increasing the cruising ability of the battery on the premise of consuming the battery life; or to reduce battery endurance for the purpose of extending battery life.
Next, the control method provided in the present application will be described in detail. As shown in fig. 2, which is a flowchart of an implementation manner of a control method provided in an embodiment of the present application, the method may include:
and S100, acquiring a battery use parameter, wherein the battery use parameter represents the use state data of the battery.
It will be appreciated that the demand for a battery by a user typically includes two aspects: in the first aspect, battery capacity is battery endurance, and in the second aspect, battery life. The battery capacity and the battery life are incompatible to a certain extent, that is, the larger the battery capacity is, the shorter the battery life may be; the smaller the battery capacity, the longer the battery life may be. Therefore, the balance between the battery capacity and the battery life is needed to better meet the needs of users.
It is understood that the battery may have a reduced battery life when left in a high voltage full capacity state for a long time.
In an alternative embodiment, the battery usage parameter can represent usage habits of the user and requirements of the user to a certain extent, for example, to a certain extent, whether the requirement of the user for the battery capacity is higher than the requirement for the battery life can be represented, and then the operation mode of the battery can be adjusted based on the battery usage parameter, so that the battery capacity and the battery life can be balanced.
In an alternative embodiment, the battery usage parameter in the time period may be counted based on a preset time period.
And step S110, switching to a corresponding working mode based on the battery use parameters.
Wherein the full charge voltages applied to the cells of the battery are different in different operating modes.
For a description of the full charge voltage, reference may be made to the above description, and further description is omitted here.
In an optional embodiment, for any one of the multiple operation modes, the greater the full charge voltage corresponding to the operation mode is, the greater the full capacity (i.e., the capacity of the battery cell at the full charge voltage) corresponding to the operation mode may be.
In the embodiment of the present application, a state in which the voltage of the battery cell at the two ends of the battery cell is greater than or equal to the threshold 1 and the capacity of the battery cell is greater than or equal to the threshold 2 is referred to as a high-voltage full-capacity state. The threshold 1 and the threshold 2 may be set based on actual conditions, and are not limited herein.
In an optional embodiment, the full charge voltages corresponding to different working modes are different, for example, the full charge voltage corresponding to the working mode 1 is smaller than the threshold 1, and then in the working mode 1, the battery cell is not in a high-voltage full-capacity state; the full charge voltage corresponding to the working mode 2 is greater than or equal to the threshold 1, and in the working mode 2, the battery cell may be in a high-voltage full-capacity state.
It can be understood that, in the case that the full charge voltage corresponding to the operation mode is greater than or equal to the threshold 1, the smaller the full charge voltage corresponding to the operation mode is, the shorter the time that the battery cell is in the high-voltage full-capacity state may be.
In an alternative embodiment, if the demand of the user for the battery capacity is higher than the demand for the battery life, the battery can be controlled to switch to the working mode corresponding to the maximum full charge voltage based on the battery use parameter; if the user's demand for battery life is greater than the demand for battery capacity, the battery may be controlled to switch to an operating mode corresponding to a minimum full charge voltage based on the battery usage parameters.
For example, assume that the battery has three modes of operation, namely: the battery management system comprises a working mode 1, a working mode 2 and a working mode 3, wherein if the full charge voltage corresponding to the working mode 1 is 4V (volt, the same applies below), the full charge voltage corresponding to the working mode 2 is 4.2V, and the full charge voltage corresponding to the working mode 3 is 4.45V, if the requirement of a user on the battery capacity is higher than the requirement on the battery life, the battery can be switched to the working mode 3 based on the battery use parameters; if the user's demand for battery life is higher than the demand for battery capacity, the battery may be switched to operating mode 1 based on the battery usage parameters.
The application provides a control method, which comprises the steps of firstly obtaining battery use parameters, wherein the battery use parameters represent the use state data of a battery, and switching to corresponding working modes based on the battery use parameters, wherein full charge voltages applied to a battery cell of the battery under different working modes are different. It can be understood that, if the full charge voltage corresponding to the battery cell is relatively large, the corresponding full capacity is relatively large, and the time that the battery cell of the battery is in the high-voltage full capacity state may be longer, which may result in a shortened life of the battery cell; if the full charge voltage corresponding to the battery cell is smaller and the corresponding full capacity is smaller, the time that the battery cell of the battery is in a high-voltage full capacity state is possibly shorter, the service life of the battery cell of the battery can be prolonged, and the service life of the battery is prolonged; the battery is controlled to be switched to the corresponding working mode based on the battery use parameters, so that the purpose of increasing the cruising ability of the battery on the premise of consuming the service life of the battery is achieved; or to reduce battery endurance for the purpose of extending battery life.
In an alternative embodiment, the usage status data of the battery may be various, and the following are provided but not limited to in this application:
the first method comprises the following steps: the method includes the steps that accumulated storage time of a battery cell of the battery is in a high-voltage full-capacity state, wherein the battery cell is in the high-voltage full-capacity state under the condition that the voltage of the battery cell is larger than or equal to a first set value (namely a threshold value 1) and the electric quantity of the battery cell is larger than or equal to a second set value (namely a threshold value 2).
The high voltage full capacity state is exemplified below.
The full charge voltage applied to the cell of the battery is different in different operating modes, assuming that the battery has three operating modes, namely: the working mode comprises a working mode 1, a working mode 2 and a working mode 3, wherein if the full charge voltage corresponding to the working mode 1 is 4V, the full charge voltage corresponding to the working mode 2 is 4.2V, and the full charge voltage corresponding to the working mode 3 is 4.45V.
In the embodiment of the present application, the number of the operation modes of the battery may be 2, 3, 4, or 5, …, and the like, and the embodiment of the present application does not limit the number of the operation modes. The above description assumes that the battery has 3 operation modes for illustration only and is not intended to limit the present application.
In an optional embodiment, the voltage of the battery cell is greater than or equal to the first set value and corresponds to a threshold range, for example, if the maximum full charge voltage is 4.45V in different operation modes, and if the first set value is 4.35V, the threshold range corresponding to the voltage of the battery cell being greater than or equal to the first set value is [4.35V,4.45V ].
In another optional embodiment, the voltage of the battery cell is greater than or equal to the first set value and may correspond to a specific value, for example, if the maximum full charge voltage is 4.45V in different operation modes, and if the first set value is 4.45V, the specific value corresponding to the voltage of the battery cell being greater than or equal to the first set value is 4.45V.
Next, full capacity in the high-voltage full capacity state will be described by taking an example in which the maximum full charge voltage is 4.45V and the first set value is 4.35V. The voltage across the cell is [4.35V,4.45V ], and the capacity of the cell is also large, for example, when the voltage across the cell is 4.35V, the capacity of the cell is 98 kw, when the voltage across the cell is 4.45V, and the capacity of the cell is 100 kw, the full capacity in the high-voltage full-capacity state means that the capacity range of the cell is [98 kw, 100 kw hour ]. The second set point may be 98 kilowatt-hours.
In an alternative embodiment, the second set point may be determined based on the first set point; alternatively, the first set value may be determined based on the second set value.
The cumulative storage time will be described below.
The battery is assumed to have three modes of operation, namely: the working mode comprises a working mode 1, a working mode 2 and a working mode 3, wherein if the full charge voltage corresponding to the working mode 1 is 4V, the full charge voltage corresponding to the working mode 2 is 4.2V, and the full charge voltage corresponding to the working mode 3 is 4.45V.
Assuming that the first set value is 4.1V, since the full charge voltage corresponding to the operation mode 1 is 4V less than the first set value, the battery is not in a high-voltage full capacity state in the operation mode 1; since the full charge voltage corresponding to the operation mode 2 is 4.2V greater than 4.1V, the battery may be in a high-voltage full capacity state in the operation mode 2; similarly, in the operation mode 3, the battery may be in a high-voltage full capacity state.
In an optional embodiment, the usage state data of the battery may include an accumulated storage time of the cell of the battery in the high-voltage full-capacity state, that is, a storage time period when the cell is in the high-voltage full-capacity state in the operation mode 2 + a storage time period when the cell is in the high-voltage full-capacity state in the operation mode 3 is equal to the accumulated storage time. It is understood that the greater the cumulative storage time, the faster the battery life is reduced; the smaller the accumulated storage time, the slower the battery life is reduced.
And the second method comprises the following steps: and storing the battery cell in a high-voltage full-capacity state within a set time period.
Here, the high voltage full capacity state is the same as the first mentioned "high voltage full capacity state", and the detailed description thereof will be omitted.
For example, the set time period may be one day, and in the above example, the total time period during which the cells of the battery are in the high-voltage full-capacity state in one day may be the storage time mentioned above.
It can be understood that before the battery leaves the factory, the service life of the battery is usually tested through software simulation, so that the battery can leave the factory after being verified. In an optional embodiment, the testing process may be completed based on the storage time of the battery cells in the high-voltage full-capacity state within the set time period. In an alternative embodiment, the simulation time required for equivalent use of the battery for two years and equivalent use for three years can be tested at different storage times (set time period is one day). Then, the test results may be as follows:
TABLE 1 test results
Figure BDA0002108294910000081
Referring to table 1 above, the longer the storage time of the battery cell in the high-voltage full-capacity state (i.e., the storage time per day shown in table 1 above) is within a set period of time, the shorter the life of the battery may be, and the longer the simulation time may be required for an equivalent 2-year (or 3-year) life; conversely, the smaller the storage time of a cell of the battery in a high-voltage full-capacity state, the longer the life of the battery may be, and the shorter the simulation time may be required for an equivalent 2-year (or 3-year) life.
It will be appreciated that the longer the simulation time, the more complex the software testing, and the less accurate the test results may be. Therefore, the simulation time can be reduced by shortening the storage time of the battery in a high-voltage full-capacity state in a set time period, and the development process can be optimized.
In an optional embodiment, the accumulated storage time of the battery cell in the high-voltage full-capacity state may be obtained based on the storage time of the battery cell in the high-voltage full-capacity state in the set time period.
It is understood that the battery is in different environmental temperatures, and the battery life is affected to different degrees, for example, if the battery is in a high (or low) temperature environment, the battery life may be consumed more rapidly, and the accumulated storage time obtained by directly adding the storage times based on the different environmental temperatures may not be accurate, i.e. an equivalent accumulated storage time needs to be obtained.
In an optional embodiment, the accumulated storage time mentioned in the embodiment of the present application is equivalent accumulated storage time, and the process of obtaining the equivalent accumulated storage time may specifically include:
acquiring the ambient temperature of the battery; and obtaining the accumulated storage time based on the ambient temperature of the battery and the storage time of the battery cell of the battery in a high-voltage full-capacity state at the corresponding ambient temperature.
In an optional embodiment, the storage time provided in the embodiment of the present application is an equivalent storage time, and the process of obtaining the equivalent storage time may include:
within a set time period, obtaining the ambient temperature of the battery; and obtaining the storage time based on the ambient temperature of the battery and the storage time of the battery cell of the battery in a high-voltage full-capacity state at the corresponding ambient temperature.
In an optional embodiment, different temperature coefficients may be set for different environmental temperatures, and the accumulated storage time of the battery cell in the high-voltage full-capacity state may be obtained based on the temperature coefficients and the storage time of the battery cell in the high-voltage full-capacity state at the corresponding environmental temperatures. In an optional embodiment, the temperature coefficient may be used as a weight, and the storage time of the battery cell in the high-voltage full-capacity state is subjected to weighted summation to obtain the equivalent accumulated storage time.
For example, if the ambient temperature of the battery is [20, 35 ℃), the corresponding temperature coefficient is 1, and the storage time of the battery cell in the high-voltage full-capacity state is assumed to be 50 hours in this temperature range; the temperature coefficient corresponding to the environmental temperature of the battery is (35 ℃, 60 ℃) is 1.2, the storage time of the battery cell of the battery in the high-voltage full-capacity state in the temperature range is 60 hours, the temperature coefficient corresponding to the environmental temperature of the battery is [5 ℃,20 ℃) is 0.6, the storage time of the battery cell of the battery in the high-voltage full-capacity state in the temperature range is 55 hours, and then the equivalent accumulated storage time of the battery cell in the high-voltage full-capacity state is obtained as follows: 1 × 50+1.2 × 60+0.6 × 55 ═ 155 (hr).
In an alternative embodiment, the battery may have at least two operation modes, namely a first operation mode and a second operation mode, wherein in the first operation mode, the full-charge voltage applied to the cell is a first voltage, and the full capacity of the cell is a first capacity at the first voltage; in the second operation mode, the full charge voltage applied to the cell is a second voltage, and the full capacity of the cell is a second capacity at the first voltage.
The term "full capacity" referred to in the embodiments of the present application means the capacity of a cell at a full charge voltage.
In an optional embodiment, the full charge voltage corresponding to the battery cell in the first operating mode of the battery is greater than the full charge voltage in the second operating mode, and optionally, the full charge voltage corresponding to the battery cell in the first operating mode of the battery may be the maximum full charge voltage, that is, the battery cell has the strongest cruising ability in the first operating mode; optionally, in the first operating mode, the full charge voltage corresponding to the battery cell may be lower than the maximum full charge voltage.
The full charge voltage of the battery in the second operating mode may be lower than the full charge voltage in the first operating mode. Then the first voltage is greater than the second voltage; the first capacity corresponding to the first voltage is greater than the second capacity.
For example, assuming that the battery has two operation modes, a first operation mode and a second operation mode, assuming that a full-charge voltage corresponding to the battery cell in the first operation mode, that is, a first voltage is 4.45V, and a first capacity may be 100 kilowatt-hours; the battery is in a second mode of operation, the second voltage is 4.4V, and the second capacity may be 80 kwh.
Referring to the description in the foregoing step S100, the battery in the high-voltage full capacity state may affect the life of the battery. In an alternative embodiment, the state that the battery is in the state that the voltage is greater than or equal to the threshold 1 and the battery capacity is greater than or equal to the threshold 2 may be referred to as a high-voltage full-capacity state in the embodiment of the present application. Assuming that the first voltage is a voltage greater than the threshold value 1, the second voltage may be a voltage greater than or equal to the threshold value 1, that is, even if the battery is in the second operation mode, there is a possibility that the battery may be in the high-voltage full capacity state for some time, but since the second voltage is smaller than the first voltage, the time that the battery is in the high-voltage full capacity state in the first operation mode is generally shorter than the time that the battery is in the high-voltage full capacity state in the second operation mode. For example, if the threshold 1 is 4.35V, the first voltage is 4.45V, and the second voltage is 4.4V, then under the same conditions, the terminal device consumes the electric energy of the battery, so that the time for the battery to drop from 4.4V to 4.35V is shorter than the time for the battery to drop from 4.45V to 4.35V, and therefore the time for the battery to be in the high-voltage full-capacity state in the first operation mode is generally longer than the time for the battery to be in the high-voltage full-capacity state in the second operation mode.
In an alternative embodiment, the first voltage is a voltage greater than or equal to threshold 1 and the second voltage is a voltage less than threshold 1. For example, assuming that the threshold 1 is 4.35V, the first voltage may be 4.45V, and the second voltage may be 4.3V, so that the battery cell is not in the high-voltage full-capacity state in the second operation mode.
In an optional embodiment, since the full-charge voltages applied to the battery cells of the battery in the first operating mode and the second operating mode are different, the battery capacity and the battery life can be balanced by switching between the first operating mode and the second operating mode. For example, the battery life may be extended by switching the battery to the second operating mode such that the battery cannot be in a high voltage full capacity state or in a high voltage full capacity state for a short time to extend the life of the cells of the battery; if the user wants the battery to have better endurance, the battery may be switched to the first mode of operation.
In an alternative embodiment, if the battery usage parameter at least includes the accumulated storage time, the process of switching to the corresponding operation mode in step S110 may include at least one of the following two cases based on the battery usage parameter.
In the first case: if the accumulated storage time is less than or equal to the first specific value, the operation mode is switched to the first operation mode.
In an alternative embodiment, in the following application scenario, the accumulated storage time of the battery in the high-voltage full-capacity state may be less than or equal to a first specific value.
Application scenario 1: the user has just purchased the battery, or the terminal device carrying the battery, which may be a "new" battery.
Application scenario 2: the user has purchased the battery or the terminal device carrying the battery for a long time, but the battery or the terminal device carrying the battery is used a very small number of times and the battery is rarely charged.
It can be understood that, in application scenario 1, since a new battery or a new terminal device is used, the user still has a certain demand for the cruising ability of the battery, so that the user needs to switch to the first working mode, and if the user does not want to switch to the first working mode, the user may think that the user has just bought the battery or the terminal device soon, the cruising ability of the battery is reduced, so that the user experience is poor.
It can be appreciated that in application scenario 2, since the user rarely charges the battery, even though the battery is in the first operation mode, the voltage across the battery cell is relatively low, i.e., the battery is not in a high-voltage full-capacity state. It is possible to switch to the first mode of operation. Therefore, when the user uses the battery or the terminal equipment occasionally, the battery is considered to have stronger cruising ability. Otherwise, the user may think that he is not using the battery or the terminal device frequently, and the battery is charged less frequently, but the endurance of the battery is reduced rapidly.
In an alternative embodiment, the battery may be maintained in the first operating mode if the accumulated storage time is less than or equal to a first specified value. The first operation mode is kept, i.e. the second operation mode is not switched to in a short time.
It should be noted that the first specific value may be different in different practical applications, and may be specifically determined based on practical needs. For example, the first specific value may be 720 hours.
In the second case: a second specific value can be set, and if the accumulated storage time is greater than or equal to the second specific value, the operation mode is switched to a second operation mode.
In an alternative embodiment, in the following application scenario, the accumulated storage time of the battery in the high-voltage full-capacity state may be greater than or equal to a second specific value.
Application scenario 1: the user has purchased the battery, or the terminal device carrying the battery, for a long time and often charges the battery, i.e. the battery may be an "old" battery.
In an alternative embodiment, the first particular value is less than the second particular value.
It will be appreciated that in application scenario 1, the battery is already an "old" battery, and the endurance is already very different from the endurance just purchased, so that the battery may be switched to the second mode of operation without sacrificing battery life in order to extend endurance, otherwise the battery may soon be unusable and the user may need to re-purchase a new battery.
Because the battery is in the first operating mode, the battery life is shortened more rapidly than in the second operating mode, and if the accumulated storage time is greater than or equal to the second specific value and is still in the first operating mode, the battery may be out of service soon, and the user needs to buy a new battery again. Therefore, when the accumulated storage time is greater than or equal to the second specific value, the second working mode is switched to prolong the service life of the battery, and the user experience is better.
In an alternative embodiment, if the accumulated storage time is greater than or equal to a second specific value, the battery may be locked in the second operating mode, and "locked" indicates that the battery is not switched to the first operating mode.
It should be noted that the second specific value may be different in different practical applications, and may be specifically determined based on practical needs. For example, the second specific value may be 1440 hours.
In an optional embodiment, if the battery usage parameter at least includes a storage time of the battery cell in the high-voltage full-capacity state within the set time period, the process of switching to the corresponding operating mode in step S110 may further include at least any one of the following two cases based on the battery usage parameter.
In the third case: if the accumulated storage time is greater than or equal to the third specific value, the second working mode is switched to.
In an optional embodiment, in the following application scenario, the accumulated storage time is greater than a first specific value and less than a second specific value, and the storage time is greater than or equal to a third specific value.
Application scenario 1: after the battery or the terminal carrying the battery is fully charged (i.e., the battery is already in a high voltage full capacity state), the battery or the terminal carrying the battery is in a resting state, i.e., the battery or the terminal carrying the battery may not be frequently used by the user.
Application scenario 2: batteries or terminals carrying batteries may often be in a charged state, e.g. the batteries or terminal equipment carrying the batteries may be connected to an external power source at all times.
In the two application scenarios, the battery endurance requirement of the user is low, so that the user can switch to the second operating mode to mainly prolong the service life of the battery.
It should be noted that the third specific value may be different in different practical applications, and may be specifically determined based on practical needs. For example, the third specific value may be 6 hours.
In a fourth case: if the accumulated storage time is greater than the first specific value and less than the second specific value and the storage time is less than the fourth specific value, the first operating mode is switched to, wherein the third specific value is greater than the fourth specific value.
In an optional embodiment, in the following application scenario, the accumulated storage time is greater than a first specific value and less than a second specific value, and the storage time is less than or equal to a fourth specific value.
Application scenario 1: the battery or the terminal carrying the battery may be frequently used by the user.
Application scenario 2: the battery or the terminal carrying the battery may often be in a non-charging state.
In the application scenario, the user has a high requirement on the cruising ability of the battery, so that the battery can be switched to the first operating mode. Because the endurance of the battery in the first operating mode is higher than the endurance of the battery in the second operating mode.
It should be noted that the fourth specific value may be different in different practical applications, and may be specifically determined based on practical needs. For example, the fourth specific value may be 5 hours.
In order to facilitate the understanding of the above four cases by those skilled in the art, the following description is made with reference to fig. 3.
Step 1: and (3) judging whether the accumulated storage time is less than or equal to a first specific value (for example, 720 hours), if so, executing the step (2), and if not, executing the step (3).
Step 2: and switching to the first working mode.
And step 3: and (4) judging whether the accumulated storage time is greater than or equal to a second specific value (for example, 1440 hours), if so, executing the step 4, and if not, executing the step 5.
And 4, step 4: and switching to a second working mode.
And 5: if the accumulated storage time is greater than the first specific value (e.g., 720 hours) and less than the second specific value (e.g., 1440 hours), determining whether the storage time is greater than or equal to a third specific value (e.g., 6 hours), if so, executing step 4, and if not, executing step 6.
Step 6: and judging whether the storage time is less than a fourth specific value (for example, 5 hours), if so, executing the step 2, and if not, executing the step 4.
The above description has been made on the conditions under which the first operation mode and the second operation mode are switched. The percentage capacity parameter of the battery displayed, which is involved in the switching process between the first operation mode and the second operation mode, will be described below.
The percentage capacity parameter of the battery is explained below.
In an operating mode, it is assumed that the full charge voltage in the operating mode is voltage 1, the capacity (i.e., capacity) of the battery cell at the voltage 1 is capacity 1, and if the current capacity of the battery cell is capacity 2, the ratio of the capacity 2 to the capacity 1 is a capacity percentage parameter.
The percentage capacity parameter is described below by taking the terminal device as a mobile phone as an example.
Fig. 4 is a schematic diagram of an implementation of the percentage capacity parameter of the mobile phone.
As shown in fig. 4, "19%" displayed by the handset is one representation of the capacity percentage parameter.
In an optional embodiment, since full charge voltages applied to the battery cells of the battery in different operation modes are different, and full capacities of the battery cells are different at different full charge voltages, capacity percentage parameters corresponding to the battery cells are different in different operation modes. For example, assuming that the first capacity in the first operation mode is 100 kilowatt-hours, the second capacity in the second operation mode is 80 kilowatt-hours, and the current capacity of the cell is 60 kilowatt-hours, then the capacity percentage parameter of the cell is 60% (60/100) in the first operation mode, and the capacity percentage parameter of the cell is 75% (60/80) in the second operation mode.
It can be understood that, since the capacity percentage may be displayed on a display screen included in the battery or a display screen included in the terminal device carrying the battery, for example, as shown in fig. 4, if the operating mode of the battery is switched, the capacity percentage parameter is also switched accordingly, and then the user experience may be poor.
Still taking the above example as an example, if the battery is switched from the second operating mode to the first operating mode, the capacity percentage parameter is switched from 75% to 60%, for example, the user is using the smart phone, if the displayed capacity percentage parameter suddenly decreases from 75% to 60%, the user may feel that the battery endurance of the smart phone is poor, that is, the capacity percentage parameter suddenly decreases without using the smart phone, and the user experience is not good; for another example, if the battery is switched from the first operating mode to the second operating mode, the capacity percentage parameter is switched from 60% to 75%, for example, the user is using a smart phone, and if the displayed capacity percentage parameter suddenly rises from 60% to 75%, the user may feel that the battery is damaged, and the user experience is not good.
Based on this, in the embodiment of the present application, when the operating mode of the battery is switched, the generated instruction enables the terminal device corresponding to the battery to keep displaying the capacity percentage parameter in the previous operating mode (i.e., the operating mode before switching), and the process may include at least the following two cases.
The first method comprises the following steps: if the battery is switched from the second operating mode to the first operating mode, a first control instruction may be generated, where the first control instruction is used to control (for example, a display in a terminal device corresponding to the battery or a display included in the battery) to keep displaying a first capacity percentage parameter, where the first capacity percentage parameter represents a ratio of a current capacity of the battery cell to a second capacity, that is, the capacity percentage parameter in the second operating mode is still displayed.
Still taking the above example as an example, if the battery is switched from the second operation mode to the first operation mode, the capacity percentage parameter is not switched from 75% to 60%, but still remains 75%, and if the battery is charged or discharged, the electronic device displays the first capacity percentage parameter in the second operation mode although the electronic device is actually in the first operation mode, so that the sudden drop of the capacity percentage parameter does not occur, and the user experience is relatively good.
And the second method comprises the following steps: if the battery is switched from the first operating mode to the second operating mode, a second control instruction may be generated, where the second control instruction is used to control (for example, a display in a terminal device corresponding to the battery or a display included in the battery) to keep displaying a second capacity percentage parameter, where the second capacity percentage parameter represents a ratio of the current capacity of the battery cell to the first capacity, that is, the capacity percentage parameter in the first operating mode is still displayed.
For example, in the above example, if the battery is switched from the first operation mode to the second operation mode, the capacity percentage parameter is not switched from 60% to 75%, but remains 60%, and if the battery is charged or discharged, the electronic device is actually in the second operation mode, but the second capacity percentage parameter displayed by the electronic device is the capacity percentage parameter in the first operation mode, so that the sudden increase of the capacity percentage parameter does not occur, and the user experience is relatively good.
In an alternative embodiment, if the display of the terminal device corresponding to the battery or the display of the battery keeps displaying the capacity percentage parameter in the previous operation mode when the operation mode of the battery is switched, the battery may be overcharged or not charged to the full capacity when the battery is in the charging state.
For example, referring to fig. 5a, a diagram of a relationship between a current capacity of a battery cell and a capacity percentage parameter is shown, wherein a slope line 41 represents the relationship between the current capacity of the battery cell and the capacity percentage parameter in the first operation mode, and a slope line 42 represents the relationship between the current capacity of the battery cell and the capacity percentage parameter in the second operation mode.
As can be seen from fig. 5a, in the first operation mode, if the current capacity of the battery cell reaches the first capacity (e.g., 100 kw-hr), the capacity percentage parameter is 100%. In the first operating mode, if the current capacity of the cell reaches a second capacity (e.g., 80 kilowatt-hours), the capacity percentage parameter is 80%. In the second operating mode, if the current capacity of the cell is a second capacity (e.g., 80 kilowatt-hours), the capacity percentage parameter is 100%.
If, in the second operating mode, the current capacity of the battery cell is the second capacity, the second operating mode is switched to the first operating mode, and if the capacity percentage parameter (100%) corresponding to the battery cell in the second operating mode is still displayed, assuming that the battery is in the charging state, then, since the displayed capacity percentage parameter is 100%, the user sees that the capacity percentage parameter is already 100%, and may not continue to charge, it can be understood that the battery cell may continue to charge for 20 kilowatts, which is referred to as a case where the battery cell cannot be charged to full capacity.
If in the first operating mode, if the current capacity of the battery cell is the second capacity, the first operating mode is switched to the second operating mode, and if the capacity percentage parameter in the first operating mode is still displayed (80%), if the battery is in a charging state, the user may think that the battery is not fully charged and may continue to charge the battery, but in the second operating mode, when the current capacity of the battery cell is the second capacity, the actual capacity percentage parameter in the second operating mode has reached 100%, and the actual battery has already been charged, which is called an overcharge condition.
In an optional embodiment, when the operating mode of the battery is switched, the embodiment of the present application may further cause, through the generated instruction, to switch to the capacity percentage parameter in the current operating mode (i.e., the switched operating mode) when an appropriate time is reached, where the process may include at least the following two cases.
The first method comprises the following steps: if the battery is switched from the second working mode to the first working mode and the battery is in a charging state, generating a third control instruction if the current capacity of the battery core is increased to a third capacity; the third capacity is the capacity of the battery cell when the first capacity percentage parameter is reached in the first operating mode; the third control instruction is used for controlling and displaying a first actual capacity percentage parameter, and the first actual capacity percentage parameter represents a ratio of the current capacity of the battery cell to the first capacity.
In an optional embodiment, if the battery is switched from the second operating mode to the first operating mode and the battery is in a charging state, the cell capacity of the battery will continuously increase, and if the cell capacity of the battery increases to a third capacity, the representation reaches an appropriate time, that is, a ratio of the third capacity to the first capacity is the same as a ratio of the capacity of the cell at the switching time (that is, the time of switching from the second operating mode to the first operating mode) to the second capacity. That is, the third capacity is the capacity of the battery cell when the first capacity percentage parameter corresponding to the switching time is reached in the first operating mode, a third control instruction may be generated, where the third control instruction is used to instruct the electronic device to display a first actual capacity percentage parameter, where the first actual capacity percentage parameter represents a ratio of the current capacity to the first capacity, where the current capacity may change along with the charging duration, and the current capacity is the third capacity at a time when the capacity of the battery cell of the battery increases to the third capacity.
For example, as shown in fig. 5b, assuming that the first capacity in the first operation mode is 100 kilowatt-hour, the second capacity in the second operation mode is 80 kilowatt-hour, assuming that the cell capacity corresponding to the time (i.e., the switching time) when the battery is switched from the second operation mode to the first operation mode is 60 kilowatt, the capacity percentage parameter corresponding to the switching time is 75% (i.e., 60/80), and since the capacity percentage parameter in the second operation mode is kept displayed, the capacity percentage parameter is kept displayed at 75%. If the battery is in a charging state, the capacity of the battery will continuously increase, and if the cell capacity reaches 75 kilowatt-hours (i.e., the cell capacity increases to the third capacity), the ratio of the third capacity to the first capacity (i.e., 75/100 ═ 75%) is the same as the ratio of the cell capacity at the switching time to the second capacity (i.e., 60/80 ═ 75%), then at the switching time to the time when the cell capacity increases to the third capacity, although the cell capacity increases from 60 kilowatt-hours to 75 kilowatts-hours, the displayed capacity percentage parameter (e.g., 75%) is unchanged; after the time point when the cell capacity rises to the third capacity, the third control instruction may control to display the first actual capacity percentage parameter, that is, the capacity percentage parameter in the first operating mode, for example, if the cell capacity corresponding to a time point after the time point when the cell capacity rises to the third capacity is 90 kilowatt-hours, the displayed capacity percentage parameter is 90% (that is, 90/100), and is not 112.5% (that is, 90/80); i.e. the percentage capacity parameter is shown by the black bold arrow sloping line in figure 5 b.
In summary, if the battery is switched from the second operating mode to the first operating mode and the battery is in the charging state, the cell capacity of the battery displays the capacity percentage parameter in the second operating mode before the switching time, the capacity percentage parameter in the second operating mode at the switching time is kept unchanged during the time from the switching time to the time when the cell capacity increases to the third capacity, and the capacity percentage parameter in the first operating mode is displayed after the time when the cell capacity increases to the third capacity.
And the second method comprises the following steps: if the battery is switched from the first working mode to the second working mode and the battery is in a discharging state, if the current capacity of the battery is reduced to a fourth capacity, generating a fourth control instruction, wherein the fourth capacity is the capacity of the battery when the second capacity percentage parameter is reached in the second working mode; the fourth control instruction is used for controlling and displaying a second actual capacity percentage parameter, and the second actual capacity percentage parameter represents a ratio of the current capacity of the battery cell to the second capacity.
In an optional embodiment, if the battery is switched from the first operating mode to the second operating mode and the battery is in a discharging state, the cell capacity of the battery is continuously decreased, and if the cell capacity of the battery is decreased to a fourth capacity, the battery is characterized to reach a suitable time, that is, a ratio of the fourth capacity to the second capacity is the same as a ratio of the cell capacity at a switching time (that is, a time when the battery is switched from the first operating mode to the second operating mode) to the first capacity, that is, the fourth capacity is the capacity of the battery when a second capacity percentage parameter corresponding to the switching time is reached in the second operating mode, a fourth control instruction may be generated, the fourth control instruction is used for instructing the electronic device to display a second actual capacity percentage parameter, wherein the second actual capacity percentage parameter represents a ratio of the current capacity to the second capacity, and wherein the current capacity changes with a discharging duration, and when the capacity of the battery cell of the battery is reduced to a fourth capacity, the current capacity is the fourth capacity.
For example, as shown in fig. 5c, assuming that the first capacity in the first operating mode is 100 kilowatt-hour, the second capacity in the second operating mode is 80 kilowatt-hour, assuming that the cell capacity corresponding to the time (i.e., the switching time) when the battery is switched from the first operating mode to the second operating mode is 75 kilowatt, the capacity percentage parameter corresponding to the switching time is 75% (i.e., 75/100), since the capacity percentage parameter in the first operating mode is kept displayed, i.e., 75% is kept displayed. If the battery is in a discharging state, if the cell capacity reaches 60 kilowatt-hour (i.e. the cell capacity is reduced to the fourth capacity), the ratio of the fourth capacity to the second capacity (i.e. 60/80 is 75%) is the same as the ratio of the cell capacity at the switching time to the first capacity (i.e. 75/100 is 75%), then at the switching time to the time when the cell capacity is reduced to the fourth capacity, the cell capacity is reduced from 75 kilowatt-hour to 60 kilowatt-hour, but the 75% is still displayed unchanged; after the time point when the cell capacity decreases to the fourth capacity, the electronic device may be instructed by the fourth control instruction to display a second actual capacity percentage parameter, that is, the capacity percentage parameter in the second operating mode, for example, if the cell capacity corresponding to a time point after the time point when the cell capacity decreases to the fourth capacity is 40 kilowatt-hours, then the capacity percentage parameter is 50% (i.e., 40/80), and not 40% (i.e., 40/100); i.e. the percentage capacity parameter is shown by the black bold arrow sloping line in figure 5 c.
In summary, if the battery is switched from the first operating mode to the second operating mode and the battery is in a discharge state, the cell capacity of the battery displays the capacity percentage parameter in the first operating mode before the switching time, the capacity percentage parameter in the first operating mode at the switching time is kept unchanged when the switching time is equal to the time when the cell capacity is decreased to the fourth capacity, and the capacity percentage parameter in the second operating mode is displayed after the time when the cell capacity is decreased to the fourth capacity.
