Fig. 1 is referred to, Fig. 1 is a kind of schematic flow diagram of charging method provided in an embodiment of the present invention.In the present embodiment The executive agent of charging method is terminal, and terminal has quick-charge function.Terminal can be mobile eventually for mobile phone, panel computer etc. End.Charging method as shown in Figure 1 may include following steps：

S101：If detect being currently at charged state, the corresponding first state index ginseng of current operating conditions is obtained Number.

Terminal accesses charging equipment when detecting in normal work by charging inlet, and charging equipment is exported to terminal Charging voltage, charging current, when being charged to terminal, terminal recognition is to be currently at charged state.Wherein, charged state can Being that high pressure fills state soon, or high pressure high current fills state soon.The state of filling refers to that charging equipment is keeping filling to high pressure soon Charging voltage is lifted in the case that electric current is constant, terminal is charged using charging voltage higher；High pressure high current is fast The state of filling refers to that charging equipment improves charging current and charging voltage simultaneously, using charging voltage higher and higher is filled Electric current charges to terminal.Charging equipment can be charger, external power source, can also can provide setting for power supply It is standby, for example, computer.Charging equipment can be charged using the rapid nitridings of high pass Quick Charge 2.0 to terminal, be filled Piezoelectric voltage can be divided into 5 volts (V), 9 volts (V), 12 volts (V), 20 volts (V), and maximum charging current can be 3 amperes (I), minimum charging voltage is 5V, and maximum charging voltage is 20V.When being charged to terminal using USB by computer, at present Maximum charging current be 2 amperes (I).It is understood that terminal can also can provide at least two chargings using other The charging technique of power carries out quick charge to terminal, is not limited herein.

Terminal is obtained under charged state, the corresponding first state index parameter of current operating conditions.Terminal can also be obtained Running temperature in the charge state.

Obtain under charged state, the corresponding first state index parameter of current operating conditions refers to obtain terminal and be in fill During electricity condition, corresponding first state index parameter when the current application for running, process and response user operate.First state Index parameter can include but is not limited to reflect the parameter of fluency, and/or, the response time.Reflect that the parameter of fluency can be with Frame per second is included but is not limited to, and/or, pause frequency etc..

Wherein, the summation of the respective running temperature of each heater members when terminal can count terminal operating in terminal, obtains To the running temperature of terminal.Because the main heater members in terminal are processor, therefore, terminal can also be by processor Running temperature is identified as the running temperature of terminal.

Processor can include central processing unit (Central Processing Unit, CPU), and/or, image procossing Device (Graphics Processing Unit, GPU).S102：Obtain the corresponding preset state index of the current operating conditions Parameter, and obtain current charge power.

Wherein, current charge power is the product of current charging voltage and current charging current.

In no particular order sequentially, terminal can simultaneously perform S101 and S102 to S101 and S102.

When terminal prestored in terminal being in uncharged state, the corresponding preset state index ginseng of each running status Number.Terminal gets under charged state current under the corresponding first state index parameter of current operating conditions and uncharged state During the corresponding preset state index parameter of running status, compare first state index parameter and preset state index parameter.It is different The corresponding preset state index parameter of running status may be identical, it is also possible to it is different.

Alternatively, terminal is when current running temperature values are got, the running temperature that will can also be got with it is default Temperature threshold is compared.Due to terminal processor operationally, running temperature all the time be no more than 50 degrees Celsius, preset temperature Threshold value can be 50 degrees Celsius (DEG C), but be not limited to this, can also be configured according to actual conditions, not be limited herein.

When comparative result is that first state index parameter is more than preset state index parameter, S103 is performed.

In other embodiments, when comparative result is that first state index parameter is equal to preset state index parameter, and work as When preceding running temperature is less than or equal to preset temperature threshold value, terminal can also keep carrying out terminal with current charge power Charge.

It is understood that current running temperature is more than preset temperature threshold value, and/or, current charge power is more than When presetting minimum charge power, charging equipment can be controlled to be charged to terminal with the first charge power, wherein, first charges Power is less than current charge power, and the first charge power is more than or equal to default minimum charge power；Terminal can be by shelves Charge power is reduced, until the first charge power is to preset minimum charge power, and current running temperature is more than preset temperature During threshold value, charging equipment can be controlled to stop to terminal charge, or prompting user stops to terminal charge.

When current running temperature is more than preset temperature threshold value, it is also possible to which directly control charging equipment stops being filled to terminal Electricity, or prompting user stops to terminal charge.

S103：If the first state index parameter is more than the preset state index parameter and the current charging work( Rate is more than presets minimum charge power, then control charging equipment to be charged to terminal with the first charge power；Wherein, described One charge power is less than the current charge power, and first charge power presets minimum charging more than or equal to described Power.

When first state index parameter minimum fills more than preset state index parameter and current charge power more than default During electrical power, terminal recognition is under same running status, the state that the state index parameter before charging is substantially better than after charging refers to Mark parameter, current charge power is too high, and the stability of the excessive influence terminal operating of charge power is, it is necessary to reduce charge power. Terminal determines the first charge power according to current charge power, so as to control charging equipment to enter to terminal with the first charge power Row charges.Wherein, the first charge power is less than current charge power, and the first charge power is more than or equal to current charging mould The corresponding minimum charge power of formula.

Wherein, if current charged state fills state soon for high pressure, terminal can reduce charging voltage and be filled so as to reduce Electrical power；If current charged state fills state soon for high pressure high current, terminal can reduce charging voltage and/or reduction is filled Electric current, so as to reduce charge power.

It is understood that multi gear charge power has been prestored in terminal, every grade of charge power one charging voltage of correspondence And a charging current, and every grade of charge power is different.High pressure is filled under state soon, corresponding to the charge power of different gears Charging voltage it is different, and charging current corresponding to the charge power of different gear is identical.High pressure high current fills shape soon Under state, the charging voltage corresponding to the charge power of different gears identical may be likely to difference, the charge power of different gears Corresponding charging current identical may be likely to difference.Carried out so that current charged state fills state soon for high pressure as an example below Explanation.

It is assumed that current charged state fills state, current this four gear of charge mode support 5V, 9V, 12V, 20V soon for high pressure Charging voltage, current charging voltage is 12V, and it is 5V to preset minimum charging voltage, and terminal is more than when first state index parameter During preset state index parameter, charging equipment can be controlled to be charged to terminal with the charging voltage of 9V or 5V.

Controlling charging equipment can be in the method that the first charge power is charged to terminal：Terminal by charging voltage from Current charging voltage is reduced to the first charging voltage, so that charging equipment is filled with the first charge power to terminal Electricity.First charging voltage is less than current charging voltage, and the first charging voltage is corresponding more than or equal to current charge mode Preset minimum charging voltage.Current charging voltage is more than presets minimum charging voltage.

Control charging equipment can also be in the method that the first charge power is charged to terminal：Terminal is according to current Charging voltage determines the first charging voltage, and sending the charge control comprising the first charging voltage value to charging equipment instructs, to control Charging equipment processed exports the first charging voltage when charge control instruction is received to terminal.It is understood that end When high pressure fills state soon, if current charging voltage is to preset minimum charging voltage, terminal will keep current charging electricity Pressure is constant.

Terminal in high pressure high current fill state soon when, if current charging voltage be preset minimum charging voltage, eventually End can also reduce charging current, and when current charge power is equal to and presets minimum charge power, keep current charging Voltage and charging current are constant.

It is understood that terminal is after S103 is performed, returns to S101 and enter downstream, and the first charge power is known Charge power that Wei be not current.

Such scheme, if terminal is detected is currently at charged state, obtains corresponding first shape of current operating conditions State index parameter；The corresponding preset state index parameter of the current operating conditions is obtained, and obtains current charge power； If the first state index parameter more than the preset state index parameter and the current charge power more than it is default most Low charge power, then control charging equipment to be charged to the terminal with the first charge power.Terminal is according to charged state First state index parameter, dynamic adjustment charge power, ensure that terminal in the case of stable operation, improve the effect that charges Rate, it is to avoid cause the situation of fluctuation of service, loss of data or damage because charge power is too high.

Fig. 2 is referred to, Fig. 2 is a kind of schematic flow diagram of charging method that another embodiment of the present invention is provided.This implementation The executive agent of charging method is terminal in example, and the executive agent of charging method is terminal in the present embodiment, and terminal has quick Charge function.Terminal can be the mobile terminals such as mobile phone, panel computer.Charging method as shown in Figure 2 may include following steps：

S201：If detect being currently at charged state, the corresponding first state index ginseng of current operating conditions is obtained Number, and obtain current running temperature.

Terminal is obtained under charged state, the corresponding first state index parameter of current operating conditions, and is obtained in charging Running temperature under state.

Processor can include central processing unit (Central Processing Unit, CPU), and/or, image procossing Device (Graphics Processing Unit, GPU).

It is understood that before S201, the charging method in the present embodiment can also include：Obtain the end When uncharged state, the corresponding performance indications parameter of each running status, and referred to according to the corresponding performance of each running status The corresponding preset state index parameter of each running status described in mark parameter setting.

Specifically, terminal is in normal work, obtains under uncharged state, the corresponding performance indications of each running status Parameter, and the corresponding performance indications parameter of each running status is set to the corresponding preset state index parameter of each running status, And preserve the corresponding preset state index parameter of each running status.

Terminal can respectively be obtained and record terminal operating each application, each process and to respond each user operation each Self-corresponding performance indications parameter.Under the corresponding performance indications parameter of each running status refers to each running status, terminal has been transported Capable all applications, process and respond the corresponding performance indications parameter of each user operation.

Performance indications parameter can include but is not limited to reflect the parameter of fluency, and/or, the response time.Reflection is smooth The parameter of degree can include but is not limited to frame per second, and/or, pause frequency etc..It refers to fall frame in preset time period to fall frame per second Number of times.Fall that frame per second is higher or interim card rate is higher, fluency is poorer.Response time represents response user's operation required time.

For example, the current operation image treatment application of terminal or game application, when processing view data by image processor, Performance indications parameter is the parameter for reflecting fluency, and the parameter for reflecting fluency is to fall frame per second, and it is current that terminal can obtain terminal Fall frame per second under running status.Terminal is identified as frame when the time that one two field picture of drafting is spent full frame boundary is more than.Eventually End can be counted in preset time period, and the number of times for falling frame obtains frame per second.

Such as, when full frame is 60 frame per second, then as long as by 1 second frame of ÷ 60, can just show that every frame is 16 milliseconds (ms) When be the boundary of full frame, 16ms (16ms is less than per frame) is faster than per frame and is smoothness, be frame more than 16ms per frame.Assuming that 1 In second, it is 4 to fall the number of times of frame, falls frame per second for 4 times/second.

Fall frame per second it is higher represent fall frame it is more serious, fluency is poorer.In the present embodiment, can will fall frame per second grade to be divided into 4 grades below：

The first estate：1s falls frame less than 4 times, represents the order of severity of frame in acceptable scope；

Second grade：1s falls frame less than 6 times, represents the order of severity of frame slightly to fall frame；

The tertiary gradient：1s falls frame 6-9 times, represents that the order of severity of frame is general；

The fourth estate：1s falls frame more than 9 times, represents the order of severity of frame seriously to fall frame.

It is understood that frame per second grade can be set according to actual needs.Specifically, can be selected by setting interface " developer's option " unlatching " GPU present in pattern analysis " checks that GPU is presented pattern analysis bar chart and checks frame condition, and according to Actually fall frame condition and set frame per second grade.Wherein, bar chart include one parallel to abscissa parallel lines, the parallel lines pair The value answered is full frame boundary value, as smooth when the peak of any bar shaped in bar chart is less than the parallel lines；Work as bar chart In the peak of any bar shaped when being higher than the parallel lines, be frame.

S202：The corresponding preset state index parameter of the current operating conditions is obtained, and obtains current charging work( Rate.

Terminal gets the corresponding first state index parameter of current operating conditions and uncharged state under charged state During the corresponding preset state index parameter of lower current operating conditions, compare first state index parameter and join with preset state index Number, and the running temperature that will be got is compared with preset temperature threshold value.

Due to terminal processor operationally, running temperature is no more than 50 degrees Celsius all the time, and preset temperature threshold value can be with It is 50 degrees Celsius (DEG C), but is not limited to this, can also be configured according to actual conditions, is not limited herein.

When comparative result is that first state index parameter is more than preset state index parameter, S203 is performed.

When comparative result is that first state index parameter is less than or equal to preset state index parameter, and current operation temperature When degree is less than or equal to preset temperature threshold value, S204 is performed.

It is understood that current running temperature is more than preset temperature threshold value, and current charge power more than default During minimum charge power, charging equipment can be controlled to be charged to terminal with the first charge power, wherein, the first charge power Less than current charge power, and the first charge power is more than or equal to default minimum charge power；Terminal can be reduced by shelves Charge power, until the first charge power is to preset minimum charge power, and current running temperature is more than preset temperature threshold value When, charging equipment can be controlled to stop to terminal charge, or prompting user stops to terminal charge.Current running temperature is big When preset temperature threshold value, it is also possible to which directly control charging equipment stops to terminal charge, or prompting user stops to terminal Charge.

S203：If the first state index parameter is more than the preset state index parameter and the current charging work( Rate is more than presets minimum charge power, then control charging equipment to be charged to terminal with the first charge power；Wherein, described One charge power is less than the current charge power, and first charge power is more than or equal to default minimum charging work( Rate.

When first state index parameter minimum fills more than preset state index parameter and current charge power more than default During electrical power, terminal recognition is under same running status, the state that the state index parameter before charging is substantially better than after charging refers to Mark parameter, current charge power is too high, and the stability of the excessive influence terminal operating of charge power is, it is necessary to reduce charge power. Terminal determines the first charge power according to current charge power, so as to control charging equipment to enter to terminal with the first charge power Row charges.Wherein, the first charge power is less than current charge power, and the first charge power is more than or equal to current charging mould The corresponding minimum charge power of formula.Now terminal can reduce charging current, it is also possible to keep current charging current constant.

Wherein, if current charged state fills state soon for high pressure, terminal can reduce charging voltage and be filled so as to reduce Electrical power；If current charged state fills state soon for high pressure high current, terminal can reduce charging voltage or reduce and charge Electric current, so as to reduce charge power.

It is understood that multi gear charge power has been prestored in terminal, every grade of charge power one charging voltage of correspondence And a charging current, and every grade of charge power is different.High pressure is filled under state soon, corresponding to the charge power of different gears Charging voltage it is different, and charging current corresponding to the charge power of different gear is identical.High pressure high current fills shape soon Under state, the charging voltage corresponding to the charge power of different gears identical may be likely to difference, the charge power of different gears Corresponding charging current identical may be likely to difference.Carried out so that current charged state fills state soon for high pressure as an example below Explanation.It is assumed that current charged state fills state soon for high pressure, current this four gear of charge mode support 5V, 9V, 12V, 20V fills Electrical power, current charging voltage is 12V, and it is 5V to preset minimum charging voltage, and terminal is when first state index parameter is more than pre- If during state index parameter, charging equipment can be controlled to be charged to terminal with the charging voltage of 9V or 5V.

Controlling charging equipment can be in the method that the first charge power is charged to terminal：Terminal by charging voltage from Current charging voltage is reduced to the first charging voltage, to cause that charging equipment is charged with the first charging voltage to terminal. First charging voltage is less than current charging voltage, and the first charging voltage is corresponding more than or equal to current charge mode default Minimum charging voltage.Current charging voltage is more than presets minimum charging voltage.

Control charging equipment can also be in the method that the first charge power is charged to terminal：Terminal is according to current Charging voltage determines the first charging voltage, and sending the charge control comprising the first charging voltage value to charging equipment instructs, to control Charging equipment processed exports the first charging voltage when charge control instruction is received to terminal.

Further, if the first state index parameter includes the parameter of reflection fluency, S203 includes：If described anti- The parameter and the current charge power of the parameter more than default reflection fluency of fluency are reflected more than default minimum charging Power, then control charging equipment to be charged to terminal with the first charge power.

Wherein, when under charged state, current operating conditions it is corresponding fall frame per second more than identical operation shape under uncharged state State is corresponding to preset frame per second and current charge power is more than when presetting minimum charge power, and terminal control charging equipment is with the One charge power charges to terminal.Or, when under charged state, the corresponding interim card rate of current operating conditions is more than uncharged Under state during the corresponding default interim card rate of identical running status, terminal control charging equipment is carried out with the first charge power to terminal Charge.

For example, when operation in charging 10s more than 90% fall frame per second be more than do not charge it is default fall frame per second, then it is assumed that Need the charge power of reduction terminal device.

Alternatively, when terminal pre-sets at least two falls frame per second grade, if current operating conditions it is corresponding fall Belonging to frame per second fall frame per second grade it is corresponding more than identical running status under uncharged state preset belonging to frame per second fall frame per second Grade, then control charging equipment is charged with the first charge power to terminal.

For example, terminal has preset following 4 falls frame per second grade：

It is assumed that the frame per second of falling of 100% operation belongs to the first estate when not charging, carried out using a certain high voltage After charging, the frame per second grade of falling fallen belonging to frame per second of 90% same operation is down to the fourth estate (seriously falling frame), then it is assumed that should Charge power has significantly affected the operation stability of terminal, terminal one charge power grade of reduction.In next round control flow In, if fall frame per second in the case where charge power grade is reduced do not improved yet, continue to reduce a charge power, Even it is reduced to default minimum charge power.

Further, if the first state index parameter includes the response time, S203 can include：If during the response Between minimum filled more than default more than preset difference value threshold value and the current charge power with the difference between the default response time Electrical power, then control charging equipment to be charged to the terminal with the first charge power.

Terminal detects response first user in the charge state and operates the corresponding response time and under uncharged state Response first user operates the difference between the corresponding default response time, and more than preset difference value threshold value, terminal recognition is charging , considerably slower than the response speed before charging, control charging equipment is with the first charge power to the terminal for response speed under state Charged.Preset difference value threshold value can be differed from according to user's acceptable response time and is configured.

For example, the response speed of the operation in charging 10s more than 90% is considerably slower than the default response speed not charged, Then think to need the charge power for reducing terminal device successively until response speed recovers normal or is reduced to minimum charging work( Rate.

Further, if the first state index parameter includes parameter and the response time of reflection fluency, S203 Can include：If the fluency grade belonging to the parameter of the reflection fluency is more than default fluency grade, or the response Difference between time and default response time is more than preset difference value threshold value, and the current charge power is minimum more than default Charge power, then control charging equipment to be charged to the terminal with the first charge power.It is understood that terminal is being held After row S203, return to S203 and enter downstream, and the first charge power is identified as current charge power.

S204：If the first state index parameter is less than or equal to the preset state index parameter, and described current Running temperature be less than or equal to the preset temperature threshold value, then control the charging equipment with the second charge power to the end Charged at end；Wherein, second charge power is more than the current charge power, and second charge power is less than Or equal to default highest charge power；The current charge power is less than the default highest charge power.

When first state index parameter is less than or equal to preset state index parameter, and current running temperature is less than or waits When preset temperature threshold value, when terminal recognition is that terminal is in charged state, stable operation still is able to, charging work(can also be improved To improve charge efficiency, terminal determines the second charge power to rate according to current charge power, so as to control charging equipment with Two charge powers charge to terminal.Second charge power be more than current charge power, and the second charge power be less than or Equal to default highest charge power；Current charge power is more than or equal to presets minimum charge power, and less than default highest Charge power.Now terminal can be with raising charging current, it is also possible to keep current charging current constant.Current charge power During equal to default highest charge power, the charge power that terminal can keep current is constant, or is left intact.

Wherein, if current charged state fills state soon for high pressure, terminal can improve charging voltage and be filled so as to improve Electrical power；If current charged state fills state soon for high pressure high current, terminal can improve charging voltage and/or raising is filled Electric current, so as to improve charge power.

It is assumed that current charged state fills state, current this four gear of charge mode support 5V, 9V, 12V, 20V soon for high pressure Charge power, current charge power is 5V, and it is 20V to preset highest charge power, and terminal is less than when first state index parameter Or running temperature equal to preset state index parameter and current is when being less than or equal to preset temperature threshold value, can control to charge Equipment is charged with the charge power of 9V or 12V to terminal.

Controlling charging equipment can be in the method that the second charge power is charged to terminal：Terminal by charging voltage from Current charging voltage is promoted to the second charging voltage, so that charging equipment is filled with the second charging voltage to terminal Electricity.

Control charging equipment can also be in the method that the second charge power is charged to terminal：Terminal is according to current Charging voltage determines the second charging voltage, and sending the charge control comprising the second charging voltage value to charging equipment instructs, to control Charging equipment processed exports the second charging voltage when charge control instruction is received to terminal.

Further, if the first state index parameter includes the parameter of reflection fluency, S204 includes：If described anti- The parameter of the parameter less than or equal to default reflection fluency of fluency is reflected, and the current running temperature is less than described pre- If temperature threshold, then charging equipment is controlled to be charged to the terminal with the second charge power.

Wherein, when under charged state, current operating conditions it is corresponding fall frame per second it is identical less than or equal under uncharged state Running status is corresponding to preset frame per second, and current running temperature, when being less than or equal to preset temperature threshold value, terminal control fills Electric equipment is charged with the first charge power to terminal.Or, when under charged state, the corresponding interim card rate of current operating conditions The corresponding default interim card rate of identical less than or equal under uncharged state running status, and current running temperature is less than or equal to During preset temperature threshold value, terminal control charging equipment is charged with the first charge power to terminal.Second charge power is more than First charge power, and the second charge power is less than or equal to default maximum charge power.

For example, when operation in charging 10s more than 90% fall frame per second be less than or equal to do not charge it is default fall frame per second, And current running temperature is less than or equal to preset temperature threshold value, then it is assumed that need to lift the charge power of terminal device, control Charging equipment is charged with the second charge power to terminal.

Alternatively, when terminal pre-sets at least two falls frame per second grade, if current operating conditions it is corresponding fall Belonging to frame per second fall frame per second grade it is corresponding less than identical running status under uncharged state preset belonging to frame per second fall frame per second Grade, and current running temperature is less than or equal to preset temperature threshold value, then control charging equipment is with the second charge power pair Terminal is charged.

For example, terminal has preset following 4 falls frame per second grade：

It is assumed that the frame per second of falling of 100% operation belongs to the second grade when not charging, carried out using a certain high voltage After charging, the frame per second grade of falling fallen belonging to frame per second of 90% same operation is promoted to the first estate or belongs to the first estate, And current running temperature is less than or equal to preset temperature threshold value, then it is assumed that the charge power not have impact on the stable of terminal Property, terminal can lift a charge power grade.In next round control flow, if improving charge power grade In the case of fall frame per second and still fall within the second grade or the first estate, and current running temperature is less than or equal to preset temperature threshold value, A charge power is then continued to lift up, or even is promoted to default highest charge power.

Further, if the first state index parameter includes the response time, S204 can include：If during the response Between be less than or equal to the preset difference value threshold value, and the current running temperature with the difference between the default response time Less than or equal to the preset temperature threshold value, then charging equipment is controlled to be charged to the terminal with the second charge power.

Terminal detects response first user in the charge state and operates the corresponding response time and under uncharged state Response first user operates the difference between the corresponding default response time to be less than or equal to preset difference value threshold value, and current fortune Trip temperature is less than preset temperature threshold value, be identified as response speed under charged state in the response speed change before charging less or Do not change, control charging equipment is charged with the second charge power to the terminal.Preset difference value threshold value can according to user It is configured with the response time difference for receiving.Second charge power be more than the first charge power, and the second charge power be less than or Equal to default maximum charge power.

For example, the response speed of the operation in charging 10s more than 90% is with the default response speed change do not charged not It is big or do not change, and current running temperature is less than preset temperature threshold value, then it is assumed that need to lift the charge power of terminal device. In next round control flow, if response speed and the default response do not charged in the case where charge power grade is improved Velocity variations are little or do not change, and current running temperature is less than preset temperature threshold value, then lift charge power again, follows according to this Ring, until charge power is promoted into default maximum charge power.

Further, if the first state index parameter includes parameter and the response time of reflection fluency, S204 Can include：If the parameter of the reflection fluency is less than or equal to the parameter of the default reflection fluency, and the sound It is more than the preset difference value threshold value with the difference between the default response time between seasonable, and the current running temperature is small In or equal to the preset temperature threshold value, then charging equipment is controlled to be charged to the terminal with the second charge power.

It is understood that terminal is after S204 is performed, returns to S204 and enter downstream, and the second charge power is known Charge power that Wei be not current.

Such scheme, if terminal is detected is currently at charged state, obtains corresponding first shape of current operating conditions State index parameter, and obtain current running temperature；The corresponding preset state index parameter of the current operating conditions is obtained, And obtain current charge power；If the first state index parameter more than the preset state index parameter and it is described work as Preceding charge power is more than presets minimum charge power, then control charging equipment to be filled to the terminal with the first charge power Electricity；If the first state index parameter is less than the preset state index parameter, and the current running temperature is less than institute Preset temperature threshold value is stated, then controls the charging equipment to be charged to the terminal with the second charge power.Terminal is according to filling The first state index parameter and current running temperature of electricity condition, dynamic adjustment charge power, ensure that terminal steady In the case of fixed operation, charge efficiency is improved, it is to avoid cause fluctuation of service, loss of data or damage because charge power is too high Situation.

When terminal obtains uncharged state, the corresponding performance indications parameter of each running status sets each running status correspondence Preset state index parameter, with according to same running status before charging after performance indications parameter exactly dynamically adjustment fill Electrical power, improves control accuracy.
