[embodiment]
Below in conjunction with drawings and Examples charger is further specified.
As shown in Figure 1, be the charger of an embodiment.This charger comprises the first transformation module 11, output interface 12, energy-storage module 13, control unit 14, the second transformation module 15 and power divider 16.
Energy-storage module 13 is connected with output interface 12 by the second transformation module 15, and energy-storage module 13 all is connected with control unit 14 with the second transformation module 15.When the charger of present embodiment inserted, energy-storage module 13 obtained voltage, store electrical energy from the first transformation module 11.In output interface 12 chargings, energy-storage module 13 also can the while store electrical energy.14 of control units are used to control charger has the voltage input time to carry out power storage, and when not having the voltage input, with energy-storage module 13 by the second transformation module 15 to output interface 12 output charging voltages.
Wherein energy-storage module 13 can be rechargeable battery, is preferably the charging lithium ion battery.Lithium ion cell charging is adopted lithium ion battery special charging circuit.14 of control units can use the chip microcontroller controlled function.Because the general output voltage of charging lithium ion battery is 3.7V, the output charging voltage need be handled through boosting and rise to the 5V charging voltage, and therefore the second transformation module 15 is preferably booster circuit.
Power divider 16 is connected with the second transformation module 15 with the first transformation module 11, and the power output of the first transformation module 11 and the second transformation module 15 is split into two-way at least, by output interface 12 outputs.
As shown in Figure 2, be the charger module figure of another embodiment.This charger comprises the first transformation module 21, output interface 22, energy-storage module 23, control unit 24, the second transformation module 25, protective circuit 26 and detecting unit 27.
Energy-storage module 23 is connected to protective circuit 26 by the second transformation module 25, and then is connected to output interface 22, and energy-storage module 23 all is connected with control unit 24 with the second transformation module 25.When the charger of present embodiment inserted, energy-storage module 23 obtained voltage, store electrical energy from the first transformation module 21.In output interface 22 chargings, energy-storage module 23 also can the while store electrical energy.24 of control units are used to control charger has the voltage input time to carry out power storage, and when not having the voltage input, with energy-storage module 23 by the second transformation module 25 to output interface 22 output charging voltages.
Wherein energy-storage module 23 can be rechargeable battery, is preferably the charging lithium ion battery.Lithium ion cell charging is adopted lithium ion battery special charging circuit.24 of control units can use the chip microcontroller controlled function.Because the general output voltage of charging lithium ion battery is 3.7V, the output charging voltage need be handled through boosting and rise to the 5V charging voltage, and therefore the second transformation module 25 is preferably booster circuit.
As shown in Figure 3, the physical circuit figure that exports for above-mentioned power divider shunting two-way USB.Adopt power divider, do not disturb mutually in the time of can making the two-way charging.
Owing to use power divider and a plurality of charging inlet, make this charger can satisfy various demand, comprise output DC charging, output AC charging and export DC charging and output AC charging etc. without interfering with each other simultaneously.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
