For example, when the CPU runs at full load, the CPU heats, the core temperature sensor can detect that the temperature of the CPU is rising, and meanwhile, the vapor chamber can conduct heat to the battery, so that the temperature of the battery is rising.

The ambient temperature sensor is used to detect an ambient temperature, for example, an indoor temperature or an ambient temperature at which the electronic device is located. When the ambient temperature is low, the electronic device may detect a specific temperature (e.g., 5 ℃) of the current low temperature.

After the charging wake lock is added, the electronic device may be prevented from going to sleep mode, so long as there is an active wake lock on the system, the electronic device cannot go to suspend mode unless the wake lock is released. In the implementation of the application, after the electronic equipment enters the sleep state, the wake-up lock can wake up the electronic equipment, so that the logic control module can continue to process tasks; under the condition that the application or the software needs to finish task processing, the electronic equipment can release the existing wake-up lock, and the electronic equipment can enter a sleep mode.

With reference to the low-temperature charging system structure shown in fig. 3, fig. 4A is a schematic flow chart of a low-temperature charging method according to an embodiment of the present application. As shown in fig. 4A, the electronic device may include a battery temperature raising module, a logic control module, and a battery charging module, and each module may refer to the above description related to fig. 2 and 3, which is not repeated. The low temperature charging method may include, but is not limited to, the following steps:

S401: the electronic equipment acquires the first information through the logic control module.

The first information may include one or more of ambient temperature, screen status, and charging information. The data acquisition module of the logic control module can acquire the ambient temperature from the ambient temperature sensor, acquire (through display driving) the screen state of the display screen, and acquire the charging information of the battery module. The charging information may include one or more of a battery temperature, a charging port temperature, a battery power, a charger type and a charging port type, a battery current, and the like, among others. The specific process of acquiring the first information may refer to the related description in fig. 3, which is not repeated.

In one possible implementation, the first information may include ambient temperature, screen status, and charging information. The electronic device may periodically (e.g., every 10 minutes) acquire the ambient temperature, and may acquire the screen status and the charging information only if the ambient temperature is less than (or equal to) the ambient threshold temperature. Under the condition that the ambient temperature information is greater than or equal to (or greater than) the ambient threshold temperature, no other first information (i.e., screen status and charging information) need be acquired. At this time, the screen state and the charging information are required to be acquired under the condition of being less than the environmental threshold temperature, so that the necessity of the acquired information is ensured, the processing resources can be saved, and the processing accuracy is improved. In addition, periodically acquiring the ambient temperature can ensure timeliness of acquiring the ambient temperature.

The logic control module may store an ambient threshold temperature, among other things.

S402: and under the condition that the temperature rise heating is not performed, the electronic equipment judges whether the first temperature rise charging condition is met or not based on the first information through the logic control module. Executing S403 under the condition that the first warm-up charging condition is satisfied; in the case where the first temperature-raising charging condition is not satisfied, it is not performed.

After the data acquisition module of the logic control module acquires the first information, the first information can be sent to the temperature rise decision module of the logic control module. The warming decision module may determine whether the first information satisfies a first warming charging condition. And under the condition that the first temperature rise charging condition is met, a temperature rise decision module of the logic control module determines temperature rise and generates first decision information. And under the condition that the first temperature rise charging condition is not met, the temperature rise decision module of the logic control module does not process and does not generate decision information.

In a possible implementation manner, in the case that the first information includes the ambient temperature, the screen state and the charging information, the first heating charging condition may include one or more of a condition that the charger is on, the screen state is off, the battery power is in a preset power range, the charging type is in a preset charging type, the ambient temperature is less than the ambient threshold temperature, the battery current is less than the charging threshold current, and a condition that a difference between the battery temperature and the charging port temperature and the battery temperature is in a preset range.

It should be noted that the first information and the first temperature-raising charging condition are often corresponding, and when the corresponding first information exists, the first temperature-raising charging condition is judged. For example, if the first information includes an ambient temperature, the first elevated charging condition includes a condition that the ambient temperature is below an ambient threshold temperature. If the first information includes a screen state, the first temperature-raising charging condition includes a condition that the screen state is an off-screen state, and in S402, a judgment of the screen state exists in the first temperature-raising charging condition. If the first information does not have the screen state, the first temperature-rising charging condition does not have a judging condition for the screen state. If the first information includes the battery temperature and the charging port temperature, the first heating charging condition includes a condition that a difference between the battery temperature and the charging port temperature is within a first preset range and the battery temperature is within a second preset range. If the first information includes battery power, the first temperature-raising charging condition includes a condition that the battery power is within a preset power range. If the first information includes a battery current, the first elevated charging condition includes a condition that the battery current is greater than a charging threshold current. If the first information includes the charging type, the first heating charging condition includes a condition that the charging type is a preset charging type.

S403: the electronic equipment sends first decision information to the battery warming module through the logic control module.

After the logic control module generates the first decision information, the warming decision module may send the first decision information to its first messaging module. The first messaging module of the logic control module may send the first decision information to the second messaging module of the battery warming module. Correspondingly, the second messaging module of the battery warming module may receive the first decision information from the first messaging module of the logic control module.

The first decision information comprises a temperature rising instruction, and the temperature rising instruction is used for indicating the battery temperature rising module to heat the battery.

The second messaging module of the battery warming module receives the first decision information from the first messaging module of the logic control module. For example, the second messaging module may detect whether decision information is received in accordance with the first period duration. In the event that the second messaging module receives the decision information, the decision information may be sent to its heating control module. Otherwise, not transmitting. Wherein the heating control module may perform heating or stop heating based on a related instruction (e.g., a warm-up instruction or an end warm-up instruction) of the decision information.

S404: the electronic equipment sends a first reply message to the logic control module through the battery heating module.

Optionally, after the battery warming module receives the first decision information from the first messaging module of the logic control module through the second messaging module, the battery warming module may send a first reply message to the first messaging module of the logic control module. Correspondingly, the first messaging module of the logic control module may receive the first reply message sent by the second messaging module from the battery warming module.

The first reply message is a feedback message for the first decision information, and is used for determining that the battery warming module has received the first decision message.

S405: the electronic equipment obtains second information through the battery temperature rising module.

After the battery warming module of the electronic device receives the first decision information, the second information may be acquired. The second information may include one or more of a processor temperature (i.e., core temperature), a heating duration of the processor, and a number of processor warmups that have been currently performed. The core temperature can be acquired through a core temperature sensor of the processor module, and the heating duration can also be acquired through the processor module. The battery temperature rising module can store the temperature rising times of the processor, and can directly acquire the temperature rising times information of the processor. The process of obtaining the second information may refer to the related description in fig. 3, which is not repeated.

S406: the electronic device controls the processor to operate and heat based on the first decision information and the second information through the battery heating module.

And under the condition that the electronic equipment acquires the first decision information, the operation of the processor can be controlled based on the second information, so that the heat of the processor heats the battery to heat the battery.

In a possible implementation manner, if the accumulated heating frequency of the processor is smaller than or equal to the set round, the electronic device controls the processor to periodically run heating within the total heating duration of the current round. Namely, the battery temperature rising module can detect the heating duration and the nuclear temperature condition under the condition that the accumulated heating times are within the set times when the electronic equipment needs to be heated in the running process. In the heating process of one round, the battery heating module can ensure that the nuclear temperature is within the range of the preset nuclear temperature, the control processor operates according to specific frequency or period, and one round of heating can be finished under the condition that the heating duration reaches the total heating duration. Therefore, the normal use and operation heating of the processor can be ensured, the limit of the nuclear temperature and the accumulated heating times is ensured, and the service life and the use of the processor are ensured.

It should be noted that, because of the small execution period, the execution of S405 and S406 may not limit the sequence of execution in time, for example, the second information acquired according to the previous period may be heated, and the second information of the next period may also be acquired, where the number of times and the interval duration of the second information acquisition are not limited.

S407: the electronic equipment sends a first charging instruction to the battery charging module through the logic control module.

When the logic control module determines that the first temperature-increasing charging condition is satisfied, a first charging instruction may be generated based on the first information, and then the first charging instruction may be transmitted to the battery charging module. Correspondingly, the battery charging module may receive a first charging instruction from the logic control module. The first charging instruction includes a charging current. Before that, the logic control module of the electronic device may determine the charging current based on the battery temperature, wherein the first information obtained by the logic control module includes the battery temperature.

The electronic device may send a first charging instruction to the battery warming module when the logic control module determines that the current battery temperature is within the chargeable temperature range. After the battery warming module receives the first charging instruction, charging may be performed based on the present charging current.

Specifically, during the heating process, the electronic device may determine the battery temperature through the logic control module, and then may determine the charging current corresponding to the current battery temperature based on the mapping relationship between the battery temperature and the charging current range. Table 1 is a table of mapping between battery temperature and charging current (i.e., a first mapping relationship) exemplarily disclosed in an embodiment of the present application, and after determining the battery temperature, the electronic device may determine the charging current when the battery is charged through the logic control module. The logic control module stores the table, determines the current, and allows the charging module to charge according to the current.

S432: the electronic equipment sends a second charging instruction to the battery charging module through the logic control module.

S433: the electronic device stops charging the battery based on the second charging instruction through the battery charging module.

The specific operation procedures of S421 to S433 described above may refer to the related description in fig. 4A, and are not repeated.

The specific steps of fig. 4B may refer to the related descriptions in fig. 4A, which are not repeated.

In the above embodiment, the logic control module of the electronic device may determine whether the first temperature-raising charging condition is satisfied when the first information is acquired. The logic control module does not need to judge whether the heating or non-heating state is currently performed, but can directly send out a charging instruction and decision information for heating under the condition that the first heating and charging condition is met; if not, the heat treatment is not performed.

In the embodiment, the judging process of the electronic equipment is simplified, the heating condition does not need to be judged, the operation can be simplified, the processing efficiency is improved, and the resources are saved.

Based on the above description of S402 and S407 in fig. 4A, fig. 5 is a schematic flow chart of a method for heating a battery according to an embodiment of the present application. As shown in fig. 5, the method for determining the warming decision by the logic control module may include, but is not limited to, the following steps:

s501: and under the condition of the access of the charger, the logic control module starts a charging decision service.

The logic control module can acquire the charger state information of the charging port module through the data acquisition module, and then can send the charger state information to the temperature rise decision module through the data acquisition module. The details of the acquiring the related content of the first information in S401 may be referred to, which is not described in detail.

And under the condition that the state of the charger is accessed, the temperature rise decision module of the logic control module determines that the charging decision service is started currently.

In the case that the charger state is not on (unplugged), the warming decision module of the logic control module determines that the charging decision service is currently ended (or stopped to start). Specifically, the warming decision module determines to end the current charging decision service under the condition that the charger changes from the connected state to the disconnected state. And under the condition that the charger is in a non-connected state, the charging decision service is not started.

S502 to S504: the logic control module judges whether a first starting condition is met based on the first information. The order of execution of S502 to S504 is not limited. And the first start-up condition may include one or more of the steps S502 to S504. At this time, the first warm charging condition in S402 may include a first start condition. The first start-up condition may include one or more of an ambient temperature condition, a charge type condition, and an electrical quantity condition, among others. The environment temperature condition is that the environment temperature is smaller than the environment threshold temperature, the charging type condition is that the charging type is a preset charging type, and the electric quantity condition is that the electric quantity of the battery is in a preset electric quantity range. The following specifically describes S502 to S504:

s502: the logic control module determines whether the ambient temperature is below an ambient threshold temperature. In the case where the environmental temperature is lower than (or equal to) the environmental threshold temperature, S503 is performed; in the case where the ambient temperature is not lower than (or greater than) the ambient threshold temperature, S505 is performed. At this time, the first information includes an ambient temperature.

The environment threshold temperature is a temperature value preset by the logic control module, and the electronic equipment stores the temperature value.

S503: the logic control module judges whether the charging type is a preset charging type or not. Executing S504 under the condition that the charging type is a preset charging type; s505 is performed on the condition that the charge type is not the preset charge type.

The preset charging type may be a quick charging type. The fast charge type and the non-fast charge type of the charger are distinguished by the magnitude of the charge power, for example, the charge type of the charger in which the fast charge type is 40W or more; the non-quick charge type is a charge type of a charger of 40W or less. At this time, the charging type is included in the first information. In general, in the process of heating the processor, the electronic device needs to consume electric power, and when the battery charge of the electronic device is greater than the consumed electric power, the battery electric power can be ensured to be increased. In the embodiment of the application, the preset charging type can ensure the heating charging in the low-temperature environment, the electric quantity of the battery is increased, and the battery is charged rather than consumed.

Optionally, the first information may further include a charging interface type; the logic control module also needs to determine whether the charging interface type is a preset interface type. In case that the charging interface type is a preset interface type, it may be determined to perform S504; otherwise, S505 is executed. In fact, the preset interface Type may be a Type-C interface.

S504: the logic control module judges whether the battery power is in a preset power range. Executing S507 under the condition that the battery power is in a preset power range; in the case where the battery power is not within the preset power range, S505 is performed.

The preset electric quantity range indicates that the electric quantity of the current charger is the electric quantity required to be charged, and the electric quantity is out of the preset electric quantity range, which indicates that the battery does not need to be charged. For example, the preset power range is a range where the battery power is less than 99%, and charging is required, S507 is performed, and greater than or equal to 99%, and charging is not required, S505 is performed. At this time, the battery power is included in the first information.

S505: the logic control module controls the battery temperature rising module to stop heating.

Specifically, the logic control module determines that warm-up charging (determining not to heat) is not performed when the first start condition is not satisfied. The logic control module may send second decision information to the battery warming module. Correspondingly, the battery warming module may receive second decision information from the logic control module. The second decision information may instruct the battery warming module to stop the current heating process, and the battery warming module may stop heating based on the second decision information (refer to fig. 6 in particular).

Alternatively, the battery warming module may release a wake-up lock for charging heating. After the wake-up lock is released, namely, after the electronic equipment is not prevented from being in a sleep state any more, the logic control module executes the charging decision service. Before releasing the wake lock, the battery warming module may determine that the electronic device has a wake lock for heating charging.

It should be noted that, after the logic control module determines to stop heating, a second charging instruction may be sent to the battery charging module to stop charging the battery. Specific reference may be made to the descriptions of S413 and S414, and detailed descriptions thereof are omitted.

S506: the logic control module exits the charge decision service.

After the battery warming module receives the second decision information from the logic control module, the charging decision service can be exited. At this time, the second decision information carries an indication of exiting the charging decision service.

From the view of executing the processes of S505 and S506, if the electronic device does not meet the first starting condition, the current charging decision service is directly exited, that is, the electronic device does not have the basic condition of low-temperature charging, and the charging decision service does not need to be waited for being started, so that the waste of processing resources can be reduced, and the energy consumption can be saved.

S507 to S509: the logic control module judges whether the second starting condition is met or not based on the first information. The execution order of S507 to S509 is not limited, and the second start condition may include one or more of S507 to S509. At this time, the first warm charging condition in S402 may include a second start condition.

The second start-up condition may include one or more of a current condition, a battery temperature and charging port temperature condition, and a screen state condition, among others. The current condition is that the battery current is greater than the charge threshold current; the temperature conditions of the battery and the charging port are the difference between the battery temperature and the charging port temperature, and whether the battery temperature is in a preset temperature range or not; the screen state condition is that the screen state is in an off-screen state. The following specifically describes S507 to S508:

at this time, the first warm charging condition in S402 may further include a second start condition.

S507: the logic control module determines whether the battery current is greater than (or equal to) a charge threshold current. In the case where the battery current is greater than (or equal to) the charging threshold current, S508 is performed; in case the battery current is less than or equal to (or less than) the charge threshold current, S510 is performed.

The range of the charging threshold current is preset, and is specifically obtained through advanced test. For example, -200mA, to which embodiments of the application are not limited. The battery current is within the range of the charging threshold current, and refers to the current in the charging direction of the battery, i.e. the current in the battery loop goes toward the battery, and at this time, the battery acts as a consumer of the electric quantity, not a provider.

In the process of processing and heating, the battery power is required to be consumed, and in the process of charging the electronic equipment, the battery power is increased. The logic control module is used for acquiring the current in a period of time, so that the accuracy of the determined battery current is ensured.

S508: the logic control module judges the difference between the battery temperature and the charging port temperature and whether the battery temperature is in a preset temperature range. Executing S509 in case that the difference between the battery temperature and the charging port temperature is in a first preset range and the battery temperature is in a second preset range; otherwise, S510 is performed.

The preset temperature range comprises a first preset range corresponding to the difference value between the battery temperature and the charging port temperature and a second preset range corresponding to the battery temperature.

Specifically, the logic control module may determine whether the difference |t1-t2| is smaller than (or equal to) the first preset difference value (in the first preset range) when the logic control module knows that the battery temperature T1 and the charging port temperature T2 have the difference |t1-t2| in the preset range; and judges whether or not the battery temperature T1 is less than (or equal to) the battery temperature threshold value (in the second preset range). Determining that the two are in a preset range under the condition that the two are met; otherwise, the preset range is not reached. In this way, the temperature of the charging port can be ensured to be normal, when the temperature of the charging port is too high, the port is short-circuited or leaked, and in this case, the problems of use safety and charging safety exist, and the judgment logic can ensure the charging safety.

In addition, in the case where the battery temperature T1 is less than (or equal to) the battery temperature threshold value, it is necessary to raise the battery temperature, so that the condition of the battery can be ensured.

S509: the logic control module judges whether the screen state is in a screen-off state. In the case of being in the off-screen state, S509 is executed; in the case of being in the bright screen state, S510 is performed.

The logic control module judges whether the screen state is in a screen-off state, and under the condition of screen-off, the logic control module can determine to execute S509; in case of the bright screen state, S510 is performed. In this way, it can be determined that the user is using or the electronic device is running the relevant processing operation of the user on condition that the screen state is the bright screen state. Therefore, when the user uses the electronic equipment, the processing resources are guaranteed to be provided for the user preferentially, the use experience of the user can be guaranteed, and the situation that the user is blocked when using the electronic equipment is avoided.

S510: the logic control module controls the battery warming module to suspend heating.

In a possible case, the logic control module may determine that the second start condition is not satisfied or that the logic control module has performed a round of heating process (S511), temporarily keep not performing warming heating (determine not to heat). The logic control module may send second decision information to the battery warming module. Correspondingly, the battery warming module may receive second decision information from the logic control module. The heating-suspension information may instruct the battery warming module to suspend the current heating process (refer to fig. 6 in particular). After that, the logic control module may stop the heating process, i.e., perform S512.

Optionally, the logic control module may preset a first sleep duration, instruct the battery to warm up to stop running the preset program after S510 or S511 is performed, and re-perform S501, that is, start the charging decision service, after the first sleep duration.

It should be noted that, after the logic control module determines to suspend heating, a second charging instruction may be sent to the battery charging module to stop charging the battery. Specific reference may be made to the descriptions of S413 and S414, and detailed descriptions thereof are omitted.

S511: the logic control module controls the battery temperature rising module to start heating.

Specifically, the logic control module may determine that the second start condition is satisfied, and start performing warm-up charging (determining warm-up charging). The logic control module may send the first decision information to the battery warming module. Correspondingly, the battery warming module may receive the first decision information from the logic control module. The start heating information may instruct the battery warming module to start the current heating process. After the one-round charge of the heating-on process is performed, the logic control module may suspend heating (refer to fig. 6 in particular), i.e., perform S510. Wherein, the step of performing S511 is performed after a certain time is required, that is, after the heating process is performed, S510 is performed.

Optionally, the electronic device may add a wake-up lock for charging heating. After the wake-up lock is added, the electronic equipment can be prevented from being in a sleep state, namely, the logic control module is awakened according to a certain time period to execute the charging decision service. It should be noted that, the precondition of adding the wake lock is that the electronic device does not currently have the wake lock added.

It should be noted that, after the logic control module determines to start heating, the temperature of the battery may be collected from time to time, and a first charging instruction may be sent to the battery charging module to charge the battery. Specific reference may be made to the descriptions of S407 and S408 above, and detailed description is omitted.

In the embodiment of the application, after the charging decision service is started, the logic control module can determine whether the first starting condition is met or not, and determine not to charge and not to heat up under the condition that the first starting condition is not met. In the case where the first start-up condition and the second start-up condition are satisfied, the temperature raising charge may be performed. In the case where the first start-up condition is satisfied and the second start-up condition is not satisfied, the suspension of charging and heating may be performed. Therefore, the premise of charging can be guaranteed, the accuracy and the effectiveness of executing the charging decision service can be improved, the electronic equipment is enabled to be heated and charged under the condition of heating and charging, and the safety and the reliability of charging and heating are guaranteed.

Referring to fig. 4A, fig. 4B, and fig. 5, fig. 6 is a schematic flow diagram of a method for heat treatment according to an embodiment of the present application. As shown in fig. 6, the process of performing and controlling the processor to perform heating based on the decision information for the above-mentioned battery heating module is specifically described as follows:

note that, in fig. 4A, the specific process of S406 and S410 may be the operation process in fig. 6.

S601: the battery warming module initiates a heating service.

After the battery warming module starts the heating service, the execution of S602 and the following steps may be started.

S602: and the battery temperature rising module acquires decision information according to the first period duration.

The decision information may be periodically monitored by the second messaging module after the battery warming module initiates the heating service. I.e. detecting whether decision information is received or not according to the second period duration. In the event that the decision information is received, the second messaging module may send the decision information to the heating control module. The battery warming module may start the heating process or end the heating process based on the decision information through the heating control module.

The decision information may be first decision information or second decision information. In case the first decision information is received, it may be determined to perform heating, and after the second decision information is received, it may be determined to perform stopping the current heating process.

S603: and the battery temperature rising module judges whether to heat or not based on the decision information under the condition that the decision information is acquired. If it is determined that heating is performed, S605 is executed; in the case where heating is not performed, S604 is performed.

The battery warming module can judge whether to heat or not based on the decision information through the heating warming module. In the case that the heating temperature raising module receives the first decision information, the first decision information includes a temperature raising instruction, and the heating temperature raising module may determine to heat based on the temperature raising instruction, that is, execute S605. In the case where the heating temperature increasing module receives the second decision information, the second decision information includes an end temperature increasing instruction, and the heating temperature increasing module may determine to stop heating based on the end temperature increasing instruction, that is, perform S604.

S604: the battery warming module exits the heating service.

The battery warming module determines to stop heating through the heating warming module, and then may exit the heating service, i.e., end execution of the current heating software program. If the heating module is currently in a round of heating process, the heating process can be directly stopped by the heating temperature increasing module, and the heating service is exited. Specifically, the process of S412 can be regarded as being performed.

S605 to S611 are specific processes of the battery temperature increasing module for performing one heating, and may be specific processes of S406.

S605: the battery temperature rising module starts a round of heating process.

The battery heating module can start a heating process of one round through the heating module.

Wherein, the execution mode of the heating process of a specific round is different, and the heating process is specifically required to be predefined. For example, each heating cycle is performed K times, each continuous heating time is M, and the interval time between the starting time of two adjacent heating cycles is N, N > M. Specifically, the steps S606 to S611 will be described in detail.

S606: the battery warming module determines a processor core that is running a warm-up.

The number of cores of the electronic device processor may be different, e.g., a 4-core or 8-core processor. Wherein, 1 core needs to execute the charge decision service of the logic control module and the heating service of the battery heating module, and the rest core or multi-core processor can execute the preset program to heat. The preset program may be a program for reading a memory of the electronic device, and the specific function is not limited.

Alternatively, the electronic device may determine the number of processor cores to heat based on the core temperature. In a possible case, in a case where the core temperature is greater than the first temperature threshold, the number of cores of the processors in the first proportion is heated (the number of processor cores that are operated to heat is a product of the total number of processor cores and the first proportion). Heating is performed in accordance with a second proportion of the number of cores of the processor with a core temperature less than or equal to the first temperature threshold and greater than the second temperature threshold. And heating the number of cores of the processor according to the third proportion under the condition that the core temperature is less than or equal to the second temperature threshold. Wherein the first temperature threshold is greater than the second temperature threshold, and the second temperature threshold is greater than the third temperature threshold. The first ratio is less than the second ratio, which is less than the third ratio. I.e., the higher the core temperature, the fewer the number of processor cores.

Illustratively, the current number of processor cores is 8, the first temperature threshold is 5 degrees celsius, the second temperature threshold is-5 degrees celsius, and the third temperature threshold is-15 degrees celsius. The first ratio is 3/8, the second ratio is 3/4, and the third ratio is 7/8. If the number of processor cores available for heating is 7. If the current core temperature is 6 ℃,8*3/8, namely the number of the processor cores is 3; if the current core temperature is-6 ℃,8*5/8, namely the number of the processor cores is 5; if the current core temperature is-16 ℃,8 x 7/8, namely the number of the processor cores is 7. Therefore, the lower the core temperature is, the more the number of the processor cores is, so that the processor module can be ensured to heat up faster, the resources for calling the processor cores are as few as possible, the loss of the processor is reduced, the service life of the electronic equipment is prolonged, and the blocking is slowed down.

Optionally, in a case that the number of cores of each round of processors that are running heating and the number of cores that execute the heating policy are unchanged, the electronic device allocates the cores that are running heating in the current heating round and the cores that execute the heating policy in turn based on the historical core allocation results of the processors. The battery heating module of the electronic equipment is used for heating the number of the processor cores with preset number, and the heating is alternately executed according to the heating and heating rounds, or the processor cores execute the charging decision service and the heating service are alternately executed according to the rounds. At least one processor core is required to perform the heating strategy; at least one processor core is required to perform the run-time heating process of the processor.

Illustratively, the number of processor cores of the electronic device is 8 and the preset number is 7. Assume that the processor cores are n1, n2, n3, n4, n5, n6, n7, and n8, respectively. Executing a logic control module and a battery temperature rising module in the first round n1, and executing a preset program in n 2-n 8; the second round of operation n2 executes a logic control module and a battery heating module, and n1, n 3-n 8 execute a preset program; the third wheel n3 executes the logic control module and the battery temperature raising module, and the n1, n2 and n 4-n 8 execute the preset program … …, so that the kernel loss degree of each processor can be guaranteed to be almost the same as possible, the service life of the electronic equipment is prolonged, and the blocking is delayed.

S607: the battery warming module judges whether the accumulated heating times are within the set times. If the number of times is within the set number of times, executing S608; otherwise, S604 is performed.

The battery warming module may store the accumulated number of heating times through the heating control module. In the case where the current cumulative heating number is less than (less than or equal to) the set number, the number of times at which the temperature raising operation is performed may be determined by determining that the cumulative heating number is within the set number of times. Whether the accumulated heating number is within the set number is judged. The accumulated heating times are the total times of the heating rounds of the battery temperature rising module, and the accumulated times from the factory start of the electronic equipment to the current heating rounds. The processor can stop the heating service within the set times, namely, the heating service is not heated; the heating may be performed after the set number of times has been exceeded. The times of full-load operation of the processor and the times and the aging degree of the controller can be effectively controlled, so that the time of the occurrence of the blocking can be delayed, and the user experience is improved.

The execution order of S607 is not particularly limited, and may be before S608.

S608: the battery temperature rising module controls the processor core to run and heat at full load.

The battery temperature rising module can control the full-load operation of the processor core through the temperature rising decision module, heat can be generated in the operation process of the processor, and the heat is transferred to the battery module through the heat dissipation plate, so that the temperature of the battery is increased. Therefore, a specific heating hardware module is not needed, and the battery can be heated by the processor, so that the temperature of the battery is ensured to reach the chargeable temperature.

Specifically, the battery temperature rising module of the electronic device can control the processor core to heat in one round through the temperature rising decision module, the total heating duration is X, and the accumulated heating times are K in the X time period, namely, the processor core is heated for K times periodically in one round. Each continuous operation time is M, a waiting time is H, an interval time between two adjacent heating start times is N (heating period time n=m+h), and x=n×k. It can be seen that one period of the processor running heating is composed of an running time period which is a time period of the processor running heating in one period and a waiting time period which is a time period of the processor not running heating in one period.

Illustratively, the total heating duration X is 150min, the cumulative heating number K is 50, the operation duration is 2min (M), the waiting duration (H) is 1min, and the interval time N of the adjacent two heating start times is 3min.

Optionally, in the above-mentioned one-round heating process, the heating is periodic heating, for example, the above-mentioned heating is performed for 2 minutes (M), and waiting for 1 minute; the reheating is repeated for 2min … …, and the heating process is to ensure that the nuclear temperature is within the preset nuclear temperature range, so that the safety of the electronic equipment can be ensured. For a low-temperature charging environment, when the electronic equipment is heated, a higher temperature is maintained, or the nuclear temperature is increased; when heating is stopped, the lower the ambient temperature is, the faster the nuclear and battery temperatures are reduced. The battery warming module of the electronic device may determine a heating frequency or a ratio of an operating duration to a waiting duration (period duration is unchanged) based on an ambient temperature (or a core temperature when not heated). The lower the ambient temperature (or core temperature when unheated), the higher the corresponding heating frequency or ratio of the run length to the wait length.

For example, the battery warming module of the electronic device may store a mapping relationship between an ambient temperature and a ratio of a heating duration to a waiting duration. After the electronic device obtains the ambient temperature before heating, the ratio of the heating duration to the waiting duration can be determined based on the mapping relation, so that the ratio of the heating duration to the waiting duration can be determined. For example, at an ambient temperature of-5 degrees, heating for 2 minutes, waiting for 1 minute; at-15 degrees, wait for 3 minutes, 1 minute apart. Therefore, the electronic equipment can adaptively determine the heating duration in different environment temperatures, the temperature is ensured to be in a specific temperature range as much as possible, the charging time is ensured to be as long as possible, and the charging effectiveness is ensured.

S609: the battery temperature rising module judges whether the heating time length reaches the total heating time length. In case that the preset heating period is reached, S610 may be performed; in the case where the preset heating period is not reached, S611 may be performed.

The battery heating module starts timing under the condition of controlling the processor core to heat, and ends the heating of the round under the condition that the heating time length reaches the total heating time length, and S610 is executed; in the case where the total heating period is not reached, heating is continued, and S611 is performed.

Optionally, the total heating time required by different batteries is different, the lower the battery power is, the longer the time required for charging is, and the longer the heating time should be; the higher the battery charge, the shorter the charging time should be. Therefore, based on the electronic device, the mapping relationship between the battery power and the heating duration (or the functional relationship between the battery power and the heating duration) may be determined in advance, and after the current core temperature is determined, the duration (total heating duration) required for one round of heating may be determined based on the battery power. The battery warming module may then heat based on the determined first total heating duration (X). The lower the battery charge, the longer the total duration of the first heating. Like this, can guarantee that round heating makes electronic equipment's electric quantity can perhaps be close to full to can avoid round heating not full charge and reheat once, perhaps the condition of excessive heating, thereby can practice thrift the processing resource that the heating consumed, guarantee the accuracy of the duration of charging.

For example, assume that a battery temperature rising module of the electronic device stores a mapping relationship between battery power and heating duration, where the mapping relationship is that when the battery power is 0-5%, the total heating duration is 150min; when the electric quantity of the battery is 5-20%, the total heating time is 120min; when the electric quantity of the battery is 20-50%, the total heating time is 100min; when the electric quantity of the battery is 50-70%, the total heating time is 60min; when the electric quantity of the battery is 70-85%, the total heating time is 30min; when the electric quantity of the battery is 85-99%, the total heating time is 15min. Based on the mapping relation, if the current electric quantity is 30%, the electronic device can determine that the total first heating time is 100min, that is, the total time of one round of heating is heated according to the time, and the one round of heating is completed after 100 min.

S610: the battery temperature increasing module obtains the core temperature, and sleeps for a first sleep time under the condition of a first core temperature value of a core Wen Chaoguo; in the case that the core temperature is lower than the second core temperature value, heating is continued.

The battery temperature rising module can preset the nuclear temperature range through the temperature rising decision module. The core temperature range includes a first core temperature value and a second core temperature value. In the case of the first core temperature value of core Wen Chaoguo, the electronic device may sleep for a first sleep period, i.e., pause the first sleep period during the present round of heating; in the case of being lower than the second core temperature value, heating is kept, that is, S608 is continued. The first dormancy time is smaller than the preset heating total time. The first core temperature value is greater than or equal to the second core temperature value. Therefore, the nuclear temperature can be ensured to be heated within a certain temperature range, the battery can be ensured to be heated, the temperature of the processor is not too high, the processor is damaged, and the safety of the heating process and the safety of the processor are ensured.

Illustratively, the first core temperature value is 50 degrees celsius and the second core temperature value is 10 degrees celsius. When the current core temperature is higher than 50 ℃, pausing for 20min (first dormancy duration); when the current core temperature is lower than 10 degrees celsius, heating is continued to be started.

Illustratively, the first core temperature value and the second core temperature value are both 30 degrees celsius. When the current core temperature is higher than 30 ℃, pausing for 20min (first dormancy duration); when the current core temperature is lower than 30 degrees celsius, heating is continued.

Note that S608 to S610 may be executed in parallel, and the execution sequence is not limited.

S611: the battery temperature rising module updates the temperature rising operation times and finishes the heating of the round.

After the battery temperature rising module can determine that the heating of the round is finished through the temperature rising decision module, the electronic equipment can increase the temperature rising operation times once (update) and finish the heating of the round. Thus, the accuracy of the measured temperature rise operation times can be ensured. After executing S611, the monitoring of the decision information may continue S602, ensuring that the decision information can be obtained in time to start heating.

In the above embodiment, the battery warming module may perform heating or stop heating specifically according to the decision information. During the heating process, the operation of the processor can enable the battery to quickly heat up, so that the battery is at a temperature capable of being charged. In addition, the battery is charged and full for a period of time, so that the processor can perform operation and stop operation control according to the temperature in one heating cycle, the core temperature is ensured to be in a temperature range suitable for charging, and the battery can be continuously charged, and the safety of the processor and the safety of the rechargeable battery are ensured.

As used in the above embodiments, the term "when …" may be interpreted to mean "if …" or "after …" or "in response to determination …" or "in response to detection …" depending on the context. Similarly, the phrase "at the time of determination …" or "if detected (a stated condition or event)" may be interpreted to mean "if determined …" or "in response to determination …" or "at the time of detection (a stated condition or event)" or "in response to detection (a stated condition or event)" depending on the context.

In the above embodiments, it may be implemented in whole or in part by software, hardware, firmware, or any combination thereof.
