Abstract
The utility model discloses a portable charging power supply which comprises a rechargeable battery, a charging control circuit, a boost circuit, and a discharging output circuit, wherein the charging control circuit is electrically connected with the rechargeable battery and used for the management and control of a power storage process of the rechargeable battery, and the boost circuit and the discharging output circuit are used for achieving the power output. The charging control circuit comprises a voltage transformation circuit and a DC/AC conversion circuit, wherein the voltage transformation circuit is used for voltage reduction, and the DC/AC conversion circuit is used for converting an alternating current to a direct current and inputting the direct current to the rechargeable battery. The portable charging power supply provided by the utility model can be directly charged by utilizing the commercial power, and can adapt to the commercial power with a voltage range from 110v to 220v. Moreover, there is no need to carry an additional charging device for the portable charging power supply. Accordingly, the portable charging power supply is superior to a conventional portable charging power supply in application convenience.
Description
Technical field
The utility model relates to a kind of charging device, particularly a kind of portable charged power supply that can charge to mobile terminal at any time.
Background technology
In life now, universal due to scientific and technical development and mobile Internet, people's mobile terminal carrying of going out is also increasing.And soaring year by year along with mobile terminal arithmetic speed, its power consumption problem also day by day highlights.Take mobile phone as example, and the mobile phone of a large-screen 3G network standard, the online within normal time, makes a phone call and plays games under situation, is difficult to support time a whole day and does not need charging.Believe that a lot of people ran into the awkward thing of just missing out of doors important phone but mobile phone does not have electricity.For this reason, existing manufacturer develops volume and is easy to carry now, can store certain electric weight, and when mobile terminal does not have electricity, can meet an urgent need as the portable power source equipment of mobile terminal charging temporarily.This kind equipment generally includes a rechargeable battery, a charging control circuit is that described rechargeable battery charging, a booster circuit and a discharge output circuit are for the mobile terminal electric discharge output power to needs charging.But in prior art, this portable power source equipment is from when electric power storage, it is generally the charging device by another and this portable power source coordinative composition of equipments, this charging device includes the change-over circuit that alternating current (AC) is converted to direct current (DC), also comprises DC-DC reduction voltage circuit.Yet emerging problem is that if user has only carried portable power source and left behind charging device when going out, the result causing is that user also can only use the electric weight of only depositing in portable power source, and cannot continue as portable power source, again supplements electric weight.Problem is on the other hand, and the adaptable voltage of charging device charging by portable power source in prior art is fixed often, for example, directly use 220v alternating current, when the civil power of user the country one belongs to is not 220v, just can produce great problem again like this.
Utility model content
In view of the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of portable charged power supply that can adapt to different input voltages.
To achieve these goals, a kind of portable charged power supply that the utility model provides, comprise rechargeable battery, be electrically connected to described rechargeable battery for the electric power storage process to described rechargeable battery and manage the charging control circuit of control and for realizing booster circuit and the discharge output circuit of electric energy output, wherein, described charging control circuit also comprises for input voltage being carried out to the voltage conversion circuit of step-down and for alternating current being transferred to direct current and being input to the DC/AC change-over circuit of described rechargeable battery.
As preferably, described input voltage is 110v to 220v.
As preferably, described rechargeable battery is poly-lithium battery group.
As preferably, described poly-lithium battery group comprises at least two series connection or poly-lithium battery in parallel.
Compared with prior art, portable charged power supply of the present utility model, can directly be used civil power to charge to it, can adapt to voltage range commercial power charged of 110v-220v.And without the charging device additionally carrying as portable charged power source charges, so on ease of use, be greatly better than traditional portable charged power supply.
Accompanying drawing explanation
Fig. 1 is the structural representation block diagram of portable charged power supply of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is further described in detail.
As shown in Figure 1, a kind of portable charged power supply that the utility model provides, comprise rechargeable battery 1, be electrically connected to described rechargeable battery 1 for the electric power storage process to described rechargeable battery 1 and manage the charging control circuit 2 of control and for realizing booster circuit 3 and the discharge output circuit 4 of electric energy output, wherein, described charging control circuit 2 also comprises for input voltage being carried out to the voltage conversion circuit 22 of step-down and for alternating current being transferred to direct current and being input to the DC/AC change-over circuit 21 of described rechargeable battery.Portable charged power supply of the present utility model, when work, then transfers alternating current to direct current by DC/AC change-over circuit 21 after voltage conversion circuit 22 step-downs of civil power by charging control circuit 2 and is input in rechargeable battery 1.When needs are during by rechargeable battery 1 output power, can export according to mode same as the prior art.
Booster circuit 3 in the utility model, discharge output circuit 4 all can be identical with the circuit part of the portable power source of prior art, and DC/AC change-over circuit 21 and voltage conversion circuit 22 can design with reference to the partial circuit of the charging device in prior art, portable power source being charged.Major advantage of the present utility model is to make portable power source itself directly to use civil power to charge to it, does not need to use charging device to charge to it.Voltage range commercial power charged that can adapt to 110v-220v, and without the charging device additionally carrying as portable charged power source charges, so on ease of use, be greatly better than traditional portable charged power supply.
In the present embodiment, as preferably, described input voltage is 110v to 220v.Voltage conversion circuit 22 can carry out automatic voltage adjustment according to the difference of input voltage.
In addition, as preferably, described rechargeable battery 1 is poly-lithium battery group.Further, as preferably, described poly-lithium battery group comprises at least two series connection or poly-lithium battery in parallel.
Certainly; the above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
