Afterwards, different process flows is substituted into, detection and judgement to battery types or battery temperature are completed.
The software processing flow of the battery type detection method proposed to the present embodiment with reference to Fig. 2 carries out in detail
It illustrates.
S201, a type of battery of selection（Common batteries or high-tension battery）It is inserted into the battery case of mobile phone, and
Open the mobile phone.
S202, mobile phone are in start process, electricity operation on baseband chip, after baseband chip stable operation, control reference
Power supply VREF is opened, and is the capacitance C1 chargings that capacitor element is built-in in battery by current-limiting resistance R1.
In the present embodiment, the reference power source VREF is needed to control its opening by baseband chip or be closed, Yi Zhongshe
Meter scheme is that the reference power source VREF is directly provided using baseband chip, as shown in Figure 1；Another design scheme is to use
Power panel in mobile phone provides reference power source VREF, but needs to add on the circuit of reference power source VREF connection current-limiting resistances R1
Switch element controls the switching elements conductive or disconnection by baseband chip, to realize the opening to reference power source VREF
Or it closes.For the considerations of simplifying interior of mobile phone circuit design, the present embodiment preferably uses the first design scheme.
In the process, for the mobile phone for having inserted high-tension battery, reference power source VREF is by current-limiting resistance R1
The capacitor element C1 chargings being built in high-tension battery, make the voltage at the both ends capacitor element C1 gradually rise；If being packed into mobile phone
Be common batteries, then reference power source VREF passes through the thermistor R2 ground connection in current-limiting resistance R1 and battery, the temperature of battery
The voltage value for detecting pin 2 is partial pressure values of the current-limiting resistance R1 and thermistor R2 to reference power source VREF.
S203, when charging reaches the charging time Tc of setting, baseband chip controls the reference power source VREF and closes.
In the present embodiment, the charging time Tc is preferably set to be more than or equal to capacitor element C1 from 0V to fully charged institute
The time needed.For the considerations of accelerating the mobile phone power-on time, charging time Tc values preferably between 1 to 2 second.Example
Such as：It opens reference power source VREF and after about 2 seconds, capacitor element C1 is fully charged, and the voltage at the both ends capacitance C1 tends to be steady
It is fixed, reference power source VREF is closed at this time.
After S204, delay a period of time Ts, voltage detecting is carried out to the temperature detection pin 2 of battery.
After reference power source VREF is closed, the charge stored in capacitance C1 is let out by current-limiting resistance R1 and thermistor R2
It puts.Delay time Ts is reasonably set, makes capacitor element C1 after the Ts times of discharging, the voltage at the both ends capacitance C1 remains to be maintained at
Setting value Vo or more.That is, set the time Ts discharges into time needed for setting value Vo less than capacitor element C1, and more than ginseng
Power supply VREF is examined from closing the time needed for loss of voltage.In the present embodiment, the setting value Vo is preferably greater than or equal to
0.5V is advisable with Vo=0.5V；Preferably value is advisable the time Ts in the range of 5 milliseconds ~ 50 milliseconds, preferably Ts=10mS.
When the time for closing reference power source VREF reaching Ts, baseband chip opens its analog-to-digital conversion interface ADC, reads electricity
The voltage value Vadc of the temperature detection pin 2 in pond.
If the voltage value Vadc of S205, temperature detection pin 2 is greater than the set value Vo, judgement is to be built-in with capacitor element C1
A kind of battery, i.e. high-tension battery；Otherwise, it is determined that being another type of battery, i.e. common batteries.
Due to being built-in with capacitor element C1 in high-tension battery, and closed in reference power source VREF and after the Ts times that are delayed,
Charge in capacitor element C1 not discharge off, therefore, the voltage value Vadc of the temperature detection pin 2 of battery can be more than
0.5V.And for the common batteries of no built-in capacitance device C1, since reference power source VREF is closed and is delayed the Ts times
Afterwards, the voltage of reference power source VREF has completely disappeared, and the temperature detection pin 2 of battery is grounded by thermistor R2, thus,
Voltage value Vadc=the 0V detected by temperature detection pin 2.Pass through the voltage of the temperature detection pin 2 of detection battery as a result,
Value Vadc can accurately judge that the battery being inserted into mobile phone is high-tension battery or common batteries.
It is of course also possible to select the built-in capacitance device C1 in common batteries, and keep the internal structure of high-tension battery not
Become, detection process is same as above, but testing result is opposite.That is, as the voltage value Vadc of temperature detection pin 2>When 0.5V, it is determined as general
Energization pond；As the voltage value Vadc of temperature detection pin 2<When 0.5V, it is determined as that high-tension battery, the present embodiment be not reinflated herein
