Below please refer to Fig. 2, Fig. 2 is the thin portion block schematic diagram with the portable power source device of quick-charge function of Fig. 1.The battery 1100 with the portable power source device 1000 of quick-charge function of Fig. 2, multiple input port 1201 ~ 120n, measuring circuit 1400, multiple output port 1601 ~ 160m, and treatment circuit 1700 with reference to the related description of above-mentioned Fig. 1, can not repeat them here.First will carry out further description for charging control unit 1300 below.And control of discharge unit 1500 will in illustrating after a while.
Charging control unit 1300 comprises multiple input booster circuit 1311 ~ 131n and a charging control circuit 1330.Input booster circuit 1311 ~ 131n is connected in parallel to each other.The input of each in input booster circuit 1311 ~ 131n is connected to an independent corresponding person in input port 1201 ~ 120n to receive one of them of charging power SC_1 ~ SC_n.The output of each in input booster circuit 1311 ~ 131n is connected to each other and is connected to boost bus 1390.Input booster circuit 1311 ~ 131n boosts to produce booster voltage BoostV to the voltage of charging power SC_1 ~ SC_n respectively, and exports booster voltage BoostV to boost bus 1390.In addition, input booster circuit 1311 ~ 131n can control the electric current of charging power SC_1 ~ SC_n to balance the power of input electric power PI_1 ~ PI_n, thus avoids input electric power PI_1 ~ PI_n to transship.Charging control circuit 1330 is connected between boost bus 1390 and battery 1100.Charging control circuit 1330 is in order to receive booster voltage BoostV.Charging control circuit 1330 couples of booster voltage BoostV carry out voltage to current conversion to produce charging current Ic, and export charging current Ic to battery 1100 to charge to battery 1100.
In detail, input booster circuit 1311 and be connected to independent corresponding input port 1201 to receive charging power SC_1.The voltage of input booster circuit 1311 couples of charging power SC_1 boosts to produce booster voltage BoostV, and exports booster voltage BoostV to boost bus 1390.Similarly, input booster circuit 1312 and be connected to independent corresponding input port 1202 to receive charging power SC_2.The voltage of input booster circuit 1312 couples of charging power SC_2 boosts to produce booster voltage BoostV, and exports booster voltage BoostV to boost bus 1390.Remaining input booster circuit 1313 ~ 131n can analogize it according to above-mentioned explanation.Because input booster circuit 1311 ~ 131n is parallel-connected to charging control circuit 1330 by boost bus 1390, the electric current that therefore input booster circuit 1311 ~ 131n can be provided to boost bus 1390 by charging control circuit 1330 adds up.Then, charging control circuit 1330 can carry out voltage to current conversion to produce charging current Ic for the booster voltage BoostV in boost bus 1390.
In an embodiment of the present utility model, treatment circuit 1700 is connected to input booster circuit 1311 ~ 131n and charging control circuit 1330.Treatment circuit 1700 can distinguish control inputs booster circuit 1311 ~ 131n according to multiple testing results of charging power SC_1 ~ SC_n, thus makes input booster circuit 1311 ~ 131n produce booster voltage BoostV.Treatment circuit 1700 can control charging control circuit 1330 according to measuring-signal Sm and produce charging current Ic.In detail, as described earlier, by detecting charging power SC_1 ~ SC_n, treatment circuit 1700 judges whether external electrical apparatus is connected to input port 1201 ~ 120n.When treatment circuit 1700 judges that external electrical apparatus is connected to input port 1201 ~ 120n, treatment circuit 1700 can distinguish control inputs booster circuit 1311 ~ 131n, thus makes input booster circuit 1311 ~ 131n produce booster voltage BoostV.
For example, input electric power PI_1 is received using as charging power SC_1 from an external electrical apparatus at this hypothesis input port 1201, wherein charging power SC_1 is 5 volts, 2 amperes (namely power is 10 watts), the booster voltage BoostV that treatment circuit 1700 control inputs booster circuit 1311 ~ 131n exports is 10 volts, and battery 1100 is 4 volts charging under full up state.By detecting charging power SC_1, treatment circuit 1700 judges that external electrical apparatus is connected to input port 1201.Therefore, treatment circuit 1700 can the voltage of control inputs booster circuit 1311 couples of charging power SC_1 boost to produce booster voltage BoostV.
Based on the law of conservation of energy, the voltage of charging power SC_1, after boosting process (namely boosting to 10 volts), inputs booster circuit 1311 by the electric current of output 1 ampere to charging control circuit 1330.Then, the booster voltage BoostV (10 volts) that charging control circuit 1330 provides for input booster circuit 1311 carries out voltage to current conversion.Because battery 1100 is 4 volts under the full up state of charging, therefore charging control circuit 1330 must carry out step-down process to booster voltage BoostV (10 volts).Same based on the law of conservation of energy, charging control circuit 1330 is by the charging current Ic of generation 2.5 amperes.In other words, charging control circuit 1330 charges with the electric current of 2.5 amperes to battery 1100.
In above-mentioned example, suppose that another input port 1202 receives input electric power PI_2 using as charging power SC_2 from another external electrical apparatus, wherein charging power SC_2 is 5 volts, 1 ampere (namely power is 5 watts).By detecting charging power SC_2, treatment circuit 1700 judges that another external electrical apparatus is connected to input port 1202.Now, treatment circuit 1700 can boost to produce booster voltage BoostV by control inputs booster circuit 1312 couples of charging power SC_2.
Based on the law of conservation of energy, charging power SC_2, after boosting process (namely boosting to 10 volts), inputs booster circuit 1312 by the electric current of output 0.5 ampere to charging control circuit 1330.Because input booster circuit 1311 exports the electric current of 1 ampere to charging control circuit 1330, therefore inputting booster circuit 1311 and 1312 can provide the electric current (i.e. the power of 15 watts) of 1.5 amperes to charging control circuit 1330 altogether.Then, the booster voltage BoostV (10 volts) that charging control circuit 1330 provides for input booster circuit 1311 and booster circuit 1312 carries out voltage to current conversion.Because battery 1100 is 4 volts under the full up state of charging, therefore charging control circuit 1330 must carry out switch type step-down process to booster voltage BoostV (10 volts).Same based on the law of conservation of energy, charging control circuit 1330 is by the charging current Ic of generation 3.75 amperes (15 watts divided by 4 volts).In other words, charging control circuit 1330 charges with the electric current of 3.75 amperes to battery 1100.
It can thus be appreciated that, compared to only using single rice delivery inbound port (such as only using input port 1201) to charge to the battery 1100 of portable power source device 1000, use multiple input port (such as simultaneously using input port 1201, input port 1202) larger charging current can be provided to battery 1100.That is, by using multiple input port 1201 ~ 120n to improve the charging current of battery 1100 simultaneously, the charging rate of battery 1100 can be increased widely and shorten battery 1100 and fill the full time.At this specifically be, charging power SC_1 described in above-mentioned example is 5 volts, 2 amperes, charging power SC_2 is 5 volts, 1 ampere, booster voltage BoostV is 10 volts, and battery 1100 under the full up state of charging be 4 volts only in order to illustrate, and be not used to limit the utility model.
Referring again to Fig. 2, input booster circuit 1311 ~ 131n can be controlled by treatment circuit 1700 respectively to produce stable booster voltage BoostV, thus makes input booster circuit 1311 ~ 131n adjust the electric current being supplied to charging control circuit 1330 respectively.
Be described with above-mentioned example equally.When charging power SC_1 is 5 volts, 2 ampere-hours, input booster circuit 1311 can be controlled by treatment circuit 1700 and produce booster voltage BoostV and be 10 volts and export the electric current of 1 ampere to charging control circuit 1330.In some cases, if when the electric current of the input electric power PI_1 that external electrical apparatus provides (i.e. charging power SC_1) is unstable, such as be down to 1.6 ampere-hours by 2 amperes, treatment circuit 1700 carrys out control inputs booster circuit 1311 by the testing result of charging power SC_1.Furthermore, now treatment circuit 1700 can control inputs booster circuit 1311 maintenance output booster voltage BoostV be 10 volts.But control inputs booster circuit 1311 only can provide the electric current of 0.8 ampere to charging control circuit 1330 by treatment circuit 1700.The functioning condition of all the other input booster circuits 1312 ~ 131n also can analogize it according to above-mentioned explanation.
Thus, treatment circuit 1700 learns by the testing result (such as charging power SC_1) of charging power SC_1 ~ SC_n the maximum stable performance number that each external electrical apparatus (being such as connected to the external electrical apparatus of input port 1201) can provide.In above-mentioned example, be connected to the external electrical apparatus of input port 1201 or the input booster circuit 1311 maximum stable performance number that can export and be only 8 watts (namely 5 volts be multiplied by 1.6 amperes or 10 volts are multiplied by 0.8 ampere).Because treatment circuit 1700 can learn the maximum stable performance number that the outside portable power source being connected to each input port can export, therefore treatment circuit 1700 can control the charging current Ic that charging control circuit 1330 produces maximum stable.
In addition, treatment circuit 1700 also can control the keying of each input booster circuit respectively.For example, when treatment circuit 1700 will improve the charging current of battery 1100, treatment circuit 1700 can be opened multiple input booster circuit (such as two or more) simultaneously or open multiple input booster circuit (such as 10 watts) providing larger firm power value.Thus, the power that charging control circuit 1330 can provide the multiple input booster circuits opened adds up and is converted to charging current to charge to battery 1100.Relatively, treatment circuit 1700 only can be opened an input booster circuit or open can provide the input booster circuit of less firm power value (such as 5 watts) to reduce the charging current of battery 1100.
Below will carry out further description for control of discharge unit 1500.Same with reference to Fig. 2.Control of discharge unit 1500 comprises voltage booster circuit for battery 1510 and charge/discharge control circuit 1530.Voltage booster circuit for battery 1510 is connected to battery 1100 and treatment circuit 1700.Voltage booster circuit for battery 1510 is controlled by treatment circuit 1700 and boosts to produce discharge voltage DV to the voltage Vb of battery 1100.Charge/discharge control circuit 1530 is connected to voltage booster circuit for battery 1510, treatment circuit 1700 and at least one output port 1601 ~ 160m.Charge/discharge control circuit 1530 is in order to receive discharge voltage DV.Charge/discharge control circuit 1530 is controlled by treatment circuit 1700 and produces at least one discharging current Id1 ~ Idm to carry out voltage to discharge voltage DV to current conversion.Charge/discharge control circuit 1530 provides discharging current Id1 ~ Idm to output port 1601 ~ 160m.In addition, charge/discharge control circuit 1530 can detect at least one discharging current Id1 ~ Idm, to carry out overload detection to output port 1601 ~ 160m.
For example, suppose that at this voltage Vb of battery 1100 is 4 volts, when treatment circuit 1700 detects that a mobile device (not shown) is connected to output port 1601, the voltage Vb (4 volts) that treatment circuit 1700 can control voltage booster circuit for battery 1510 pairs of batteries 1100 boosts to produce discharge voltage DV (such as 5 volts, USB voltage level).Charge/discharge control circuit 1530 couples of discharge voltage DV carry out voltage to current conversion and produce discharging current Id1.Thus, discharging current Id1 is supplied to this mobile device by output port 1601.
In sum, the portable power source device with quick-charge function described in the utility model embodiment receives multiple input electric power using as multiple charging power by multiple input port from multiple external electrical apparatus.Therefore larger charging current can be provided to the battery in portable power source device.The charging rate of battery can be increased by this and shorten battery and fill the full time.In addition, because each input booster circuit is connected to its independent corresponding input port to receive charging power, therefore treatment circuit can control the keying of each input booster circuit respectively to control the charging current of battery.
