Charger 24 is precious 22 chargings of charging, and the operation principle that can shorten the charging interval of charging precious 22 is:
In the time using charger 24 for precious 22 charging of charging, charging precious 22 is connected with charger 24, the charger detection circuit 222d of charging precious 22 has detected voltage input, first do simple 5V voltage judgement, then, charger detection circuit 222d and the charger 24 of charging precious 22 fill agreement soon based on high pass, Samsung fills soon agreement or Lian Fake and fills soon agreement and carry out communication, charger 24 can pass through current value or two the signal pin D1+ of supply pin VBUS1, voltage magnitude on D1-knows charging precious 22 needs the charging voltage of which kind of grade, the charging voltage of the precious 22 required grades of charger 24 output charging.Then, charging circuit 222b is according to the charging voltage grade of input, and the chemical characteristic of lithium ion battery 224, and battery 224 is carried out to the chargings such as preliminary filling, constant current, constant voltage.Particularly, when the voltage of battery 224 is during lower than 2V, can carry out preliminary filling; When the voltage of battery 224 is between 2V to 4.2V time, can carry out constant current charge; When the voltage of battery 224 is during higher than 4.2V, can carry out constant voltage charge.
Because charging precious 22 and charger 24 are all supported high pass and are filled soon that agreement, Samsung fill agreement soon and Lian Fake fills agreement soon, charging precious 22 and charger 24 can be on supply pin VBUS1 or the enterprising news that work of signal pin D1+, D1-, require charger 24 to export except conventional 5V DC charging voltage, the also DC charging voltage of a series of high value classes such as exportable 7V, 9V, 12V or 20V, improve maximum charge power, shorten the charging interval.
Adopt the charging voltage of high value class can shorten the cause description in precious 22 charging intervals of charging why as follows:
Taking charger 24 energy output voltage 9V, output current 1.5A, power output P1 '=9V*1.5A=13.5W(watt) as example, with existing charger 14(referring to Fig. 1) output voltage 5V, output current 1.5A, power output P2 '=5V*1.5A=7.5W comparison, consider the USB line loss of 0.45W, the precious 22 getable maximum output charge powers of charging are respectively P1=13.5-0.45=13.05W and P2=7.5-0.45=7.05W, and maximum input charge power improves (P1-P2)/P2=85%.The maximum charging current that precious 22 charge inside circuit efficiencies approach and charge inside circuit can allow if charged in two kinds of situations is enough large, suppose the corresponding constant current charge stream of output voltage 9V, output current 1.5A I1, charging interval when voltage U is T1, and the corresponding constant current charge stream of output voltage 5V, output current 1.5A I2, charging interval when voltage U is T2; And can draw according to formula electric weight Q=IT and power P=UI, in the situation of precious 22 constant current charges that charge, savable charging interval ratio is (T2-T1)/T2=(P1-P2)/P1=85/185=46%.
With respect to prior art, if USB cable impedance is higher in prior art, or charger 24 output voltages (such as being 4.75V) on the low side, the precious 12(that charges is referring to Fig. 1) charging interval can significantly elongate even and be not fully filled; And in the utility model, can be far above the maximum charging voltage of the battery of charging precious 22 due to the charging voltage to the precious 22 charge inside circuit inputs of charging, shorten the charging interval and can avoid the situation that battery is not fully filled to occur.
