It charges normal.The pause charging temperature threshold value P of the present embodiment is the first temperature threshold in first embodiment.
Step 203：Check battery of mobile phone electricity whether be full of, if not full of if keep intelligent charge state, full of if
Charging terminates.
Step 204：Obtaining battery underfill by step 203 needs the information to charge, checks in real time and monitoring mobile phone is electric
The temperature value in pond, comparative cell real time temperature and pause charging temperature threshold value P set by user, intelligence is issued according to comparative result
Charging instruction.
Step 205：The real-time battery temperature of comparative result is obtained by step 204 and is more than setting pause charging temperature threshold value P,
At this time in order not to allow battery working at high temperature, prevent temperature from continuing to raise, charge power supply of battery is cut off by charge controller
Pause is charged.
Step 206：After carrying out step 205, battery of mobile phone is in non-charged state, and battery temperature declines therewith.Compare
Battery real time temperature and the recovery charging temperature threshold value R (value is that dynamic calculates) being calculated, when battery temperature drops to
When recovering charging temperature threshold value R, charge power supply of battery is connected by charge controller, recovers battery and charges.The present embodiment it is extensive
Multiple charging temperature threshold value R is the second temperature threshold value in first embodiment.
Step 207：The fully charged information of battery is obtained by step 203, charging terminates.
As shown in fig. 6, the workflow of electricity management and control module is as follows：
Step 301：Intelligent terminal connects charge power supply, initially enters charged state.
Step 302：In the case where cell-phone battery electric-charge quantity underfill, temperature be not exceeded, mobile phone charges normal.
Step 303：Check whether the electricity of battery of mobile phone is full of, into intelligent charge state if not being full of, if filled
Expire then into stopping charged state.
Step 304：Check that battery has been filled with electricity by step 303, in order to avoid battery overcharges for a long time, electricity pipe
Charge controller cut-out charge power supply of battery is issued a command under control function to stop charging.
Step 305：Battery of mobile phone, which is in, after step 304 is performed stops charged state, and cell phone standby can cause electricity
Consumption, when electric quantity consumption falls 2% total electricity i.e. remaining capacity reaches 98%, electricity management and control function issues charging and refers to
Order, cell communication charge power supply start to charge up.Step 304 is returned again to after being full of.
Temperature threshold calculation is described below：
The present embodiment is preset mainly in combination with user's, describes pause charge threshold and the recovery of temperature management and control charging
Charge threshold is set and computational methods.The lithium battery that smart mobile phone all uses, 0~40 DEG C of the normal working temperature of lithium battery,
Limiting temperature is -20~70 DEG C.
Selection is set when pause charging temperature threshold value enables temperature management and control function by user, and setting range is 30~50 DEG C.
The real time temperature of temperature management and control module meeting instant playback battery is for reference, provides two methods to set pause charging temperature
Spend threshold value.A kind of method is selection recommendation pattern example, and module is set there are two temperature threshold example：Summer mode (42 DEG C) and winter
Season pattern (38 DEG C) selects either mode example to may be set to relevant temperature to suspend charging temperature threshold value.Another method
It is that self-defined can suspend charging temperature threshold value according to particular surroundings or needs, user, scope is between 30~50 DEG C.
After setting pause charging temperature threshold value, suspend charging after reaching pause charging temperature threshold value with battery temperature,
Then calculated according to the time span of pause charging temperature threshold value and previous charge cycle and recover charging temperature threshold value.Recovery is filled
Electro-temperature threshold value is divided into two kinds of calculations according to the size of pause charge threshold, as shown in table 1.
When suspending charging temperature threshold value in 30~40 DEG C of sections, if a upper charge cycle is more than 10 minutes, recover
The value of charging temperature is the temperature averages of a upper charge cycle；If a upper charge cycle is less than 10 minutes, recovery is filled
The value of electro-temperature is -10 DEG C of pause charging temperature threshold value.Such as pause charging temperature threshold value set by user is 35 DEG C, when temporary
Stopping calculating the battery mean temperature in a trickle charge cycle after charging as 31 DEG C, charge cycle is 22 minutes, so
The recovery charging temperature threshold value that next charge cycle starts is 31 DEG C；If charge cycle is 7 minutes, recover the temperature that charges
It is 25 DEG C to spend threshold value.
When suspending charging temperature threshold value in 40~50 DEG C of sections, recover the value of charging temperature threshold value as (pause is filled
Electric threshold value -10) DEG C.Such as pause charging temperature threshold value set by user is 50 DEG C, then the recovery that each charge cycle starts is filled
Electro-temperature threshold value is 40 DEG C.
Table 1
The advantages of this computational methods one is the duration for ensureing the step charge cycle, and week is kept when charge cycle is long
Phase duration extends the cycle when charge cycle is short with adjustment and recovery charging temperature threshold value, reduces stopping and recovers what is charged
Frequency；Second is that it controls and reduces the total time that battery in charging process is in high temperature.
Above 30~40 DEG C of preset user's selectable threshold scopes are zone of reasonableness, belong to normal temperature less than 30 DEG C；
Belong to serious fever scope higher than 50 DEG C, it can closing temperature management and control function if you need to carry out charging in this temperature range.
One specific application scenarios example is described below：
Mobile phone is connected light source of charger by user, opens the temperature management and control of intelligent charge and electricity management and control function, and selection is temporary
Stop charge threshold to start to charge up for 38 DEG C.It has filled after a period of time, battery starts to generate heat, and temperature has reached 38 DEG C, charges temporary
Stop and calculated during last charge cycle a length of 35 minutes, mean temperature is 33 DEG C.As temperature cools down, when battery temperature drops to
Start to recover to charge at 33 DEG C；Temperature arrives again at 38 DEG C after having filled 8 minutes, stops charging and according to a upper charge cycle being less than
It calculates within 10 minutes and recovers charging temperature threshold value as 28 DEG C, recover to charge until battery temperature drops to 28 DEG C, it is so repeatedly straight
To fully charged.Since battery is full of into charge mode is stopped, electricity drops to 98% after standby more than one hours, by electricity management and control
Recovery continues to charge, until being full of.It is repeated several times, until user pulls out charge power supply stopping charging.
Eighth embodiment of the invention, the flow of the secure charging method of the present embodiment with first or two embodiment it is identical, area
It is not, in Project Realization, the present embodiment can add the mode of required general hardware platform to realize by software, certainly
Can be by hardware, but the former is more preferably embodiment in many cases.Based on such understanding, the institute of the embodiment of the present invention
