Step S204, acquiring the equipment temperature of the equipment to be charged in the charging process;
Step S206, adjusting the charging current of the device to be charged according to the device temperature, the target temperature and the thermal balance current.
In this embodiment, a thermal balance current is used as a regulation target for rapid charging, where the thermal balance current is a charging current that can enable heat generation and heat dissipation of a device to be charged to reach a thermal balance state, so that the temperature of the device to be charged is kept unchanged during charging.
In this embodiment, step S206 may specifically include:
step S2061, determining a corresponding relationship between the charging current of the device to be charged and the device temperature according to the target temperature and the heat balance current;
Step S2062 of setting the charging current to the maximum charging current supported by the device to be charged in the case where the device temperature is less than or equal to a preset reference temperature;
step S2063, in the case where the device temperature is greater than the reference temperature, determining the charging current corresponding to the device temperature according to the correspondence relationship between the charging current and the device temperature.
In this embodiment, the correspondence relationship between the charging current and the device temperature in step S2061 is:
Wherein I is the charging current of the device to be charged, I max is the maximum charging current, I end is the heat balance current, t is the device temperature, t end is the target temperature, and t base is the reference temperature.
In the present embodiment, the reference temperatures in steps S2062 and S2063 may be adjusted as needed to achieve the effect of adjusting the charging current in advance or in delay.
In this embodiment, step S2063 may specifically include: determining the charging current corresponding to the device temperature according to the following formula:
In this embodiment, step S206 may specifically further include: the charging current is set to the thermal equilibrium current in the case where the device temperature is equal to the target temperature.
Further, the charging device may continue to charge with a thermal balance current and the device temperature may remain at the target temperature until charging is complete.
In this embodiment, before step S202, the method further includes: step S201, determining a thermal balance current corresponding to a target temperature of the equipment to be charged in a thermal balance state through charging debugging.
In this embodiment, since the device model and the battery model of the charging device are different, there may be a difference in the heat balance current at the same temperature corresponding to the charging device, and thus different charging devices may be charged and debugged in the primary charging process or in the device initialization process through step S201, so as to obtain a more accurate heat balance current.
In this embodiment, step S201 may specifically include:
Step S2011, setting a debug current corresponding to the target temperature;
Step S2012, performing constant current charging by using the debug current as the charging current of the device to be charged;
Step S2013, obtaining the equipment temperature of the equipment to be charged after charging for a preset time;
step S2014, when the device temperature is not equal to the target temperature, adjusting the debug current according to the device temperature;
Step S2015, determining the debug current as the thermal balance current in a case where the device temperature is equal to the target temperature.
In this embodiment, step S2014 specifically includes:
Determining a debugging relation between the charging current of the equipment to be charged and the equipment temperature according to the target temperature and the debugging current;
Reducing the debug current according to the debug relationship if the device temperature is greater than the target temperature;
And increasing the debugging current according to the debugging relation under the condition that the equipment temperature is smaller than the target temperature.
In this embodiment, the debug relation between the charging current and the device temperature is:
Wherein I is the charging current of the device to be charged, I max is the maximum charging current, I test is the debug current, t is the device temperature, t end is the target temperature, and t base is the reference temperature.
In this embodiment, when the device temperature is greater than the target temperature, reducing the debug current according to the debug relation specifically includes:
Determining a first current corresponding to a first temperature according to the following formula:
wherein I (t end +1) is the first current, and t end +1 is the first temperature;

And when the device temperature is smaller than the first temperature, adjusting the debugging current to be a value between the debugging current and the first current according to the weight ratio of the target temperature and the first temperature.
In this embodiment, if the device temperature is continuously greater than the first temperature, it is indicated that the current debug current is far greater than the thermal balance current corresponding to the target temperature. If the device temperature is greater than the target temperature and less than the first temperature, or the device temperature oscillates between the target temperature and the first temperature, the current debug current is close to the thermal equilibrium current, and the current debug current is slightly reduced.
In this embodiment, when the device temperature is less than the target temperature, increasing the debug current according to the debug relation specifically includes:
Determining a second current corresponding to a second temperature according to the following formula:
Wherein I (t end -1) is the second current and t end -1 is the second temperature;
adjusting the debug current to a value of the second current if the device temperature is less than the second temperature;
And when the equipment temperature is greater than the second temperature, adjusting the debugging current to be a value between the debugging current and the second current according to the weight ratio of the target temperature and the second temperature.
In this embodiment, if the device temperature is continuously smaller than the second temperature, it is indicated that the current debug current is far smaller than the thermal balance current corresponding to the target temperature. If the device temperature is greater than the second temperature and less than the target temperature, or the device temperature oscillates between the second temperature and the target temperature, the current debug current is close to the thermal equilibrium current, and the current debug current is slightly increased.
In this embodiment, the first temperature may be obtained by increasing the target temperature by a preset temperature threshold, and the second temperature may be obtained by decreasing the target temperature by a preset temperature threshold, and the preset temperature threshold is not limited to 1.
In this embodiment, in step S2014, the debug relation between the charging current and the device temperature of the device to be charged changes along with the adjustment of the debug current, and the adjustment of the debug current needs to be continued according to the updated debug relation until the device temperature detected in real time is continuously equal to the target temperature.
In this embodiment, through the steps S202 to S206, the target temperature and the thermal balance current corresponding to the device to be charged are used as the charging regulation and control targets, so that the device temperature in the charging process is ensured not to be higher than the target temperature, and the accurate regulation and control of the charging temperature is realized. The embodiment of the application can obtain corresponding heat balance current according to different target temperatures and different equipment models, and has wider application range.
Fig. 3 is a flow chart of a method of thermal balance current tuning according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of:
step S301, setting a current value in a thermal equilibrium state as M;
Step S302, substituting the detected temperature t into a relational expression, and calculating a charging current to start charging;
Step S303, judging whether the temperature is stable at t end;
step S304, if not, calculating a new heat balance state current value M 'according to the temperature change characteristics, wherein M=M';
Step S305, if yes, determining that the current value in the heat balance state is I end;
In this embodiment, it is first assumed that the thermal balance state current value (debug current) M is first set to be the regulation target in the charging process of the mobile phone, i.e. let I end =m, and then the detection temperature (device temperature) t of the mobile phone is obtained in real time.
In this embodiment, step S302 may specifically calculate the charging current I by the following relation:
In this embodiment, I max is the maximum charging current, I end is the thermal balance current, t is the current device temperature, t end is the target temperature, t base is the reference temperature for temperature control, and in the process of thermal balance current debugging, the real thermal balance current I end can be replaced by the debugging current I test.
In this embodiment, the maximum charging current I max may be set according to the maximum charging current of the battery charging specification, the temperature control reference temperature t base may be set according to the requirement, and the debugging process may implement the effect of adjusting the charging current in advance or in delay by modifying t base.
In this embodiment, through the relation between the charging current and the device temperature in step S302, the charging current corresponding to any temperature parameter may be calculated, so as to realize continuous linear regulation of the charging current.
In this embodiment, the step S302 may specifically include the following cases:
in case 1, if the temperature of the mobile phone is lower than the target temperature, before the temperature of the mobile phone does not reach the temperature control reference temperature, the charging current of the mobile phone is i=i max.
And 2, when the temperature of the mobile phone exceeds the reference temperature and starts to be regulated and controlled, and when the temperature of the mobile phone rises from the current temperature to the target temperature, the current is regulated and controlled from the maximum charging current to the heat balance current.
In case 3, if the initial charging temperature is higher than the target temperature, the charging current I is lower than the thermal balance current according to the calculation result of the relationship, and the temperature of the mobile phone will be reduced at this time, and when the temperature of the mobile phone is reduced from the current temperature to the target temperature t end, the current is regulated to the thermal balance state current I end. Subsequently, the charging current is maintained at I end and the charging temperature is maintained at the target temperature until the handset charge is full.
In this embodiment, assuming that the actual heat balance current value is N, since there are differences in the corresponding heat balance currents under different equipment models, different battery models, and different ambient temperatures, the initially set heat balance state current value M may be different from N, and needs to be adjusted during the charging process.
FIG. 4 is a schematic diagram showing the temperature variation characteristics corresponding to different initial thermal balance currents according to an embodiment of the present application. As shown in fig. 4, the temperature change in step S303 can be specifically classified into the following three types:
First, m=n, i.e. the initial thermal balance current value is equal to the actual thermal balance current value, when the charging current is regulated to M, the temperature of the mobile phone is stabilized at t end.
Second, M > N, namely the initial heat balance current value is higher than the real heat balance current value, when the charging current is regulated to M, the temperature of the mobile phone is higher than t end.
Specifically, if the temperature oscillates between t end and t end +1, which means that M is slightly higher than N, t end and t end +1 are substituted into the relational expression in step S302, charging currents I (t end) and I (t end +1) corresponding to t end and t end +1 are calculated, and a certain value in I (t end) and I (t end +1) is calculated as a heat balance current M' according to the calculated weight ratio of t end and t end +1; if the temperature is continuously equal to or higher than t end +1, which means that M is far higher than N, the charging current I (t end +1) corresponding to t end +1 is calculated as the heat balance current M'.
Thirdly, M < N, namely the initial heat balance current value is lower than the real heat balance current value, and when the charging current is regulated to M, the temperature of the mobile phone is lower than t end.
Specifically, if the temperature oscillates between t end and t end -1, which means that M is slightly lower than N, substituting t end and t end -1 into the relation in step S302, calculating charging currents I (t end) and I (t end -1) corresponding to t end and t end -1, and calculating a certain value of I (t end) and I (t end -1) as a heat balance current M' according to the calculated weight ratio of t end and t end -1; if the temperature is continuously less than or equal to t end -1, which means that M is far lower than N, the charging current I (t end -1) corresponding to t end -1 is calculated as the heat balance current M'.
In this embodiment, the temperature change feature in step S304 corresponds to the second and third temperature change cases described above, and step S305 corresponds to the first temperature change case.
In this embodiment, t end +1 corresponds to the first temperature, t end -1 corresponds to the second temperature, the corresponding I (t end) is the debug current, I (t end +1) is the first current, and I (t end -1) is the second current.
Specifically, the debug current is I (t end)＝Itest; the first current isThe second current is/>
Further, in the case of an initial thermal equilibrium current value (debug current) I test =m, the first current isThe second current is/>
In this embodiment, after step S304, the debug current I test =m' is substituted into the relational expression in step S302 to repeat the calculation until m=n is satisfied, and step S305 is executed.
In this embodiment, the charging current corresponding to any temperature parameter may be calculated according to the current temperature relation of the thermal equilibrium state in step S302, so as to achieve continuous linear regulation of the charging current. The heat balance current corresponding to any one of the to-be-charged equipment and any one of the target temperatures can be determined through the steps S301 to S305, so that the application range of the embodiment of the application is enlarged.
In another embodiment of the present application, taking the target temperature t end =40 ℃ and the initial input debug current as an example, assuming that the actual heat balance current I end is 6000mA, the current room temperature is 25 ℃, the initial temperature of the mobile phone is 25 ℃, the maximum charging current I max =12000 mA of the battery, and the reference temperature t base =32 ℃.
In this embodiment, the first time the device is charged specifically includes the following steps:
Step S1, firstly, calculating a heat balance current at 40 ℃;
in this embodiment, step S1 may specifically include:
step S1a, starting charging, obtaining the mobile phone temperature t in real time, and calculating the charging current I by the relation between the charging current and the mobile phone temperature (I test =8000 mA is taken as a regulation target first).
Specifically, when the temperature t of the mobile phone is less than or equal to 32 ℃, the charging current I=12000 mA; when the temperature of the mobile phone is more than 32 ℃ and less than or equal to 40 ℃, the charging current is equal to the charging currentIf the mobile phone temperature t=35 ℃, the charging current i=10500 mA is calculated. Until the charging current I decreases to I test =8000 mA, the handset temperature t=40℃.
In step S1b, since the debugging current is 8000mA higher than the real heat balance current of 6000mA, the heat generated by charging the mobile phone is higher than the heat dissipation, and the temperature of the mobile phone can be continuously increased, namely, the temperature t of the mobile phone is more than 40 ℃. And because 8000mA is far higher than 6000mA, the temperature t of the mobile phone is continuously more than or equal to 41 ℃, the charging current I=7500 mA corresponding to 41 ℃ is required to be calculated as the heat balance current M ', the calculated M' =7500 mA is taken as I test to be input, and the steps S1a to S1b are repeated.
Repeating the steps S1a to S1b for a plurality of times until the heat balance current I end approaches the true value 6000mA of the heat balance current, stabilizing the temperature of the mobile phone at 40 ℃, and taking the value I test as the input of the step S2.
Step S2, regulating and controlling the charging temperature by taking the heat balance current 6000mA as a target, detecting the temperature t of the mobile phone, and substituting the temperature t into the following relational expression to calculate the charging current:
Specifically, in the mobile phone charging process, if the mobile phone temperature t does not reach 32 ℃, the mobile phone charging current i=12000 mA. When the temperature t of the mobile phone exceeds 32 ℃, the current is continuously regulated and controlled from 12000mA to 6000mA when the temperature t of the mobile phone rises to 40 ℃. If the temperature of the mobile phone is higher than 40 ℃, the charging current I is lower than 6000mA, the temperature of the mobile phone is reduced, and when the temperature of the mobile phone is reduced to 40 ℃ from the current temperature t, the current is regulated and controlled to 6000mA. Then, the charging current is maintained at 6000mA, and the charging temperature is maintained at the target temperature of 40 ℃ until the mobile phone is full of electric quantity.
According to the embodiment of the application, the temperature change characteristics can be counted in the process of primary charging of the equipment, so that the heat balance current corresponding to any target temperature is calculated, the charging temperature is controlled below any target temperature, and the problem of rapid charging and heating of the equipment is solved.
According to the embodiment of the application, the linear regulation and control of the charging temperature and the charging current can be realized, the charging current is ensured to be always greater than or equal to the heat balance current, and the charging time is shortened under the condition of ensuring the charging efficiency of the mobile phone.
