Description

Can improve the portable power source of conversion ratio
Technical field
The utility model relates to field of power supplies, relates in particular to a kind of portable power source that improves conversion ratio.
Background technology
Charge multifunction is easily provided when the Main Function of portable power source, to various mobile electronic devices, for example, for the convenient electronic equipments such as mobile phone, notebook computer, palm player provide charging.Especially, on the road, when the situation of the inconvenient directly charging such as field, the individual portable power source of band just can charge to electronic equipment whenever and wherever possible.Portable power source is equivalent to a large reserve cell, for this bulk charging of portable power source once, just can give convenient electronic equipment charge repeatedly.
Lithium ion battery is due to the high-power height of capacity, more and more be applied to various portable power sources field, but a lot of people have general mistaken ideas for the empty target problem of capacity, think exactly portable power source target is that how many capacity just should have how many capacity, this is to be difficult to realize in fact.Give an example, the mobile phone portable power source of 5000mAh, if the iphone 4 that is 1500 milliamperes of left and right to battery capacity charges, generally may all be not fully filled for 3 times, and be 3.33 times in theory.This wherein just relates to the problem of a conversion ratio.
The conversion ratio of portable power source, is affected by the loss of 3 aspects mainly: PCBA intelligent protection plate, data wire, charging device itself.
PCBA intelligent protection plate is the core that determines portable power source security performance; can not only prevent from overcharging, cross put, the safety problem such as overcurrent, short circuit; but also controlling the voltage raising and reducing of portable power source; and the process of this buck has very large loss, the brand that some technology are coarse may here will consume and exceed two-layer above electric weight.Heating situation when its obvious external presentation is exactly charging.So this part is also the core component that determines portable power source quality.
Data wire loss is very surprising in the same old way.Because what general producer joined is all the interfaces of connecting wires of large quantities of orders from wholesale market, quality is general, needs on the equipment of large current charge at some, and data wire will lose more than 5% electric weight.
Equipment own loss is not that portable power source itself can determine, relevant with the equipment self using, different brands even, between same model, does not have different performances.This depends on the technical merit of the raw manufacturer of equipment.And in charging process, equipment is all generally to consume electric weight.
Through the evaluation and test of the third-party institution, although the conversion ratio of most of brand is in 70% left and right, the famous brand of some main flows, can be by the conversion rate control of mobile phone portable power source more than 85%, certainly the conversion ratio of saying is here not data all the time, just an average result value of entirety.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is: a kind of portable power source that improves conversion ratio is provided.
The technical solution of the utility model is: the portable power source that can improve conversion ratio; comprise MPS Charge Management unit, MPS power-supply management system, the dynamic analysis module of battery charging; in MPS Charge Management unit, be provided with battery protection unit and the booster circuit for battery raising charging voltage; and be electrically connected with MPS power-supply management system; MPS power-supply management system is provided with DC-DC converting system and MPS acousto-optic indicating module; and be connected with dynamic analysis module, utilize MPS control button to regulate.
As further improvement of the utility model, MPS Charge Management unit is for being connected with AC adapter.
As further improvement of the utility model, battery is poly-lithium battery.
As further improvement of the utility model, battery adopts series system to connect.
As further improvement of the utility model, the input of portable power source and output all adopt USB interface.
The beneficial effects of the utility model are: improve charging voltage by booster circuit line, improved conversion ratio, can realize charging for battery fast, saved the time, and energy savings, loss is few.
