Step 207.
That is, whether detecting cell voltage every the set time after cell voltage is located within the scope of safe voltage
It is reduced to except safe voltage range, if it is, needing to start charhing unit work, again fills battery full.
Step 208: being instructed based on charge control, control charhing unit executes the charging operations to battery.
In practical application, return step 202 after step 208.
Optionally, step 208 specifically includes: it is based on control instruction, control charhing unit executes the charging operations to battery,
Cell voltage is set to be increased to second voltage threshold value；Alternatively, control charhing unit executes the charging operations to battery, make cell voltage
It is increased to first voltage threshold value.
That is, when cell voltage is in tertiary voltage threshold value or less, charge the battery to filling full state, alternatively,
Safe voltage range is charged to, for example, charging to the upper limit value of safe voltage range.
Embodiment three
In order to more embody the purpose of the present invention, on the basis of the embodiment of the present invention one and embodiment two, give
A kind of application scenarios of charge control.
As shown in figure 3, giving a kind of charging control circuit in the scene, which realizes that charge control is specific as follows:
Step A: the terminal device for being inserted into adapter 302 for a long time, when in the start control circuit 307 of equipment under long-pressing
When the power key in face, the input voltage Vsys and Vsys_1 of start control circuit 307 are in connected state, this Vsys_1 warp at this time
Cross or door selection circuit 311 after, to electric power management circuit 312 power, the output end and MCU of electric power management circuit 312
The power end VDD of (Microcontroller Unit, Chinese micro-control unit) 301 is connected, and provides work to MCU301
Voltage.After MCU works together, control universal input/output interface (General Purpose Input Output 1, GPIO1)
For controlling start control circuit, so that Vsys and Vsys_1 are constantly in connected state.Here, electric power management circuit can be
At least one of below: low pressure difference linear voltage regulator (Low Dropout Regulator, LDO), DC-DC circuit
(Direct Current/Direct Current, DCDC), power management chip (Power Management IC, PMIC).
When terminal device is in open state, insertion adapter 302 charges.It is inserted into before adapter 302, passes through
Battery is system power supply.Specifically, before insertion adapter 302, metal oxide semiconductor field-effect (Metal-Oxide-
Semiconductor Field-Effect Transistor, MOS) it 306 is on state, battery Vbat and Vsys connect at this time
It is logical, using or door selection circuit 311 after, power to electric power management circuit 312, the output end of electric power management circuit 312 with
The power end VDD of MCU301 is connected, and provides operating voltage to MCU301.Here, metal-oxide-semiconductor can be p-type metal-oxide-semiconductor (Positive
MOS, PMOS) or N-type metal-oxide-semiconductor (Negative MOS, NMOS).
It is system power supply by adapter 302 when being inserted into adapter 302.Specifically, when the moment of insertion adapter 302,
Metal-oxide-semiconductor 306 close or door selection circuit 311 have at this time there are two input Vbus and Vsys_1 select any one input power
It is input to electric power management circuit 312, provides operating voltage VDD afterwards for MCU 301.When battery 305 voltage Vbat be lower than
When 4.2V 4.35V, MCU controls EN foot, and charging chip 304 is allowed to work, and adapter 302 is powered to battery 305.If
Setting Schottky diode 303 is that in order to prevent, in the insertion of no adapter 302, cell voltage is reversely filled to charging chip
304.In practical application or door selection circuit 311 selects input of the input of small voltage as electric power management circuit 312.
It when terminal device is in off-mode, is inserted into before adapter 302, metal-oxide-semiconductor 306 is on state, electric at this time
Pond Vbat and Vsys connection does not press the triggering of key pressing due to start control circuit, and Vsys and Vsys_1 are off-state,
Vsys_1 is 0, Vbus 0, and therefore, VDD 0V, MCU301 do not work.After being inserted into adapter 302, metal-oxide-semiconductor 306 is closed,
After Vbus is conducting to Vsys by Schottky diode 303, then pass through or door selection circuit 311 is input to electric power management circuit
312, so that electric power management circuit is exported VDD, powers to MCU301, MCU work.So no matter being filled in booting or off-mode
Electricity, MCU are work.
Step B: after cell voltage is charged to 4.2V 4.35V, MCU301 controls EN foot by GPIO interface and makes
Charging chip 304 stops charging.
Step C:MCU301 is as master control system, the charging voltage (Vbus) acquired by Vbus voltage sampling circuit 308,
The insertion situation for judging adapter 302, after adapter 302 is inserted into, MCU301 reads Vbus voltage sample by the port ADC1
308 collected charging voltage (Vbus) of circuit, MCU301, which is determined, an adapter insertion, such as without adapter insertion, MCU301 from
The port ADC1 can not obtain voltage value.When MCU301 has detected adapter insertion, start to start relevant timer, when fixed
When device timing length reach after certain T time (this time can be 3 days or 5 or 1 weeks), MCU301 judgement uses
Scene may be the scene of long-term insertion adapter.At this point, MCU301 control charging chip 304 works, by sending out to EN pin
Enable signal control charging chip 304 is sent to stop working, while MCU301 is worked by GPIO2 Interface Controller discharge circuit 309,
This discharge circuit 309 executes discharge operation to battery 305.With the consumption of battery capacity, cell voltage can be reduced slowly,
MCU301 reads 310 collected cell voltage (Vbat) of Vbat voltage sampling circuit by the port ADC, judges that cell voltage is
No to be reduced within the scope of safe voltage, if it is 4.2V conventional batteries, the safe voltage stored for a long time may range from 3.8V-
4.0V, if it is high pressure 4.35V battery, the safe voltage range stored for a long time is 3.7V-4.1V, this range is battery supplied
The most reasonable voltage placed for a long time that quotient provides.When cell voltage is in the safe voltage range for being suitble to place for a long time
It waits, then closes relevant discharge circuit.Battery is in the state for neither charging nor discharging at this time.The electricity of consumption, it is only electric
The in-fighting in pond itself.
Step D: the terminal device of adapter 302 is inserted into for long-time, since the in-fighting of battery itself makes cell voltage
It is reduced to 3.4V or so, MCU301 controls charging chip 304 and works, and charging chip 304 is made to charge battery 305.Alternatively,
When user pulls out adapter, so that terminal device is in mobile use state, when being charged again insertable into adapter, work as electricity
The voltage in pond is less than 4.2V or 4.35V, and MCU301 control charging chip 304 charges to battery 305, specifically, logical
The voltage input pin (VIN) for overcharging electrical chip 304 obtains the charging current of adapter 302, realizes that the charging to battery 305 is grasped
Make.
Here, step C is repeated to step D.
Charge control method based on foregoing circuit allows battery in the case where adapter is inserted into for a long time, fills to battery
Electricity is inserted into duration to after being suitably full of, by obtaining adapter, and intelligent decision adapter is in long-time insert state, then leads to
The discharge circuit work for crossing control battery, allows the voltage of battery to control the voltage range in safety.In this way, may be implemented suitable for a long time
When orchestration is inserted into, keeps cell voltage to be chronically at safe voltage range, eliminate the security risk of battery, guarantee the peace of battery
It is complete and reliable.
