Description
【Technical field】
Power technique fields are the utility model is related to, more particularly to a kind of compact power for possessing quick-charge function.
【Background technology】
With developing rapidly for electronic technology, the function of all kinds of mobile electronic terminals is increasingly abundanter.The thing followed, it is
Requirement of these mobile electronic terminals to its battery durable ability also more and more higher.And the most straight of battery durable ability is lifted at present
It is exactly to increase battery electric quantity to connect effective method.
The thing followed, it is requirement to charging rate also more and more higher with the continuous lifting of battery electric quantity.Thus,
Various rapid nitridings arise at the historic moment.The simplest understanding of quick charge is exactly the charging rate for accelerating battery, and is charged
The lifting of speed, realized by lifting the input power of charging.But the electricity that data wire generally used now can carry
Flow limited, it is impossible to simply improve the input power of charging by increase electric current.So industry employs raising charging voltage
Method improve the input power of charging.
Charging voltage is different from traditional charging scheme used by due to rapid nitriding, therefore, is using fast charge skill
In the electronic equipment of art, such as：Portable power source, mobile phone etc., it can monitor or control charging using the protocol chip of quick charge
The charge parameter of equipment, charging equipment.
Such as in the charging scheme that high pass provides, it is desirable to which the charging voltage voltage of input and output must be in 5V to 12V
Between.And it is required that the input of charging circuit must use the protocol chip of high pass, the protocol chip of high pass not only possesses association
View function is also equipped with buck functionality, i.e. the voltage of input is typically all to be depressurized afterwards the battery to charging equipment again
Group charging.
By taking compact power as an example, it means that the battery voltage in compact power can only be lower than 5V.But
When compact power charges to other charging equipments, in order to meet the requirement of quick charge, its voltage exported needs again
Lifted between 5V~12V.Assuming that the charging voltage of charging equipment is 12V, electric current 2A, then its charge power is P=
24W, then, the power that the battery pack of compact power needs to provide also is P=24W.But because the voltage of battery pack is necessary
Less than 5V, for existing battery core, can only be powered in the market using single battery, it is assumed that specifically battery core voltage is
3V, then the electric current of battery pack output is 8A, that is to say, that circuital current maximum between battery pack to booster circuit can be with
Reach 8A.It is well known that its bigger loss of electric current is also bigger in circuit, the caloric value of circuit is also higher.
Therefore, in foregoing circuit framework, the charging voltage of output is higher needed for compact power, and the loss in circuit will
Bigger, circuit caloric value also can be higher, and thus, product is unfit to do too small, otherwise can produce the problem of heat dispersion is bad, but
It is that the volume size of product can directly affect the portability that expires.
【Utility model content】
The technical problems to be solved in the utility model be to provide a kind of caloric value is smaller, the relatively low quick charge of loss just
Take formula power supply.
In order to solve the above technical problems, the utility model provides following technical scheme：
A kind of compact power, possesses quick-charge function, and it includes：Input is connect, and input protocol chip, buck is filled
Circuit, battery pack, fast charge identification chip and output end interface；Wherein：The input interface, it is electrically connected for being realized with charger
Connect；The input protocol chip, for being communicated by the input interface with the charger, determine that the charger provides defeated
Enter charge parameter and meet fast charge protocol；The buck charging circuit, possesses Bidirectional up-down pressure charging/discharging function, for this
The input voltage of charger boosted or decompression processing after to the battery pack charge；It is or anti-according to the fast charge identification chip
Output charge parameter of feedback, by being treated after the output voltage progress buck processing to the battery pack by the output interface
Charging equipment charges；The fast charge identification chip, Handshake Protocol communication is carried out with the charging equipment for being connect by the output, is known
Whether the charging equipment is not fast charge mode, and confirms the output charge parameter provided needed for the battery pack, and should
Output charge parameter feeds back to buck charging circuit；The output interface, electrically connected for being realized with the charging equipment.
The beneficial effects of the utility model are that the charging circuit of use possesses Bidirectional up-down pressure function so that this is portable
The voltage of battery pack in formula portable power source, just do not have to by fast charge protocol, the input of definition and the electricity of output end
The limitation of pressure, but battery voltage can be designed according to the actual requirements, so as to reduce the electricity between battery pack and charging circuit
Stream, circuit loss and caloric value are reduced, lift the conversion ratio of circuit.
