The charging method of existing large current charge.
Background technology
Along with the development of interfacing, TYPE_C interface gradually substitutes traditional USB2.0 interface, and in quick charge
Under the development of technology, having gradually stepped up the requirement to charging rate, increase charging current becomes fills necessarily becoming of charging technique soon
Gesture, in order to use the stable large current charge that realizes of TYPE_C, the communication modes of PowerDel ivery (PD) agreement is state
The exploit recognition method of border USB Union Recommendation.By the communication of TYPE_C interface CC line, thus realize the agreement of PD, to realize
Large current charge.
The charging process of present stage most TYPE-C interface, the electric current of charging is still at below 3A, when electric current exceedes
3A, reaches 5A, even more than during 5A, is depended on the quality of TYPC_C cable by the communication quality of CC interface, and present stage city
The quality of the TYPC_C cable on field is uneven, if cable is second-rate, and the resistance of high line, high stray inductance, high parasitic capacitance meeting
Causing communication signal frame losing, therefore communication signal cannot effectively exchange, and then causes adapter and charger to exchange
Information, thus limit TYPE-C charging under big electric current and the application of other function.
Summary of the invention
For overcoming the shortcoming of prior art, present invention aim at providing one can solve TYPE_C and rely on CC interface communication
The based on the TYPE-C interface of problem that communication abnormality causes charging system normally to work in the case of large current charge can
Stably realize the charging method of large current charge.
The present invention is realized by techniques below measure, a kind of based on TYPE-C interface can stably realize large current charge
Charging method, comprise the following steps:
S1. charging current is sampled by function control end, and judges whether charging current is less than threshold values, as less than threshold values
Then perform S3, otherwise perform next step；
S2. adjust circuit control charging current and be reduced to preset value, and perform next step；
S3. carry out communication by CC interface, after communication completes, perform next step；
S4. adjust circuit control charging current to recover to primary current to be charged.
As a kind of optimal way, it is mobile terminal that described function controls end.
As a kind of optimal way, step S3 is: carry out communication by CC interface and adapter, the adjusting module of adapter
Complete to perform next step after output state adjusts.
As a kind of optimal way, it is adapter that described function controls end.
As a kind of optimal way, step S3 is: mobile terminal from the current/voltage detection module of itself obtain electric current and
The information such as voltage, carry out communication by CC interface, perform next step after telling the information state of adapter self.
As a kind of optimal way, described function is controlled end and is adopted charging current by electric current and voltage detection module
Sample.
The invention provides one and utilize TYPE-C interface, it is possible to achieve the method for large current charge, carry out CC interface
Before communication, first charging current is sampled, judge whether charging current is less than threshold current, when higher than threshold current (meeting
Cause the electric current of communication signal frame losing) time then reduce charging current after carry out CC interface communication again, thus avoid when cable matter
The communication signal that when measuring poor, charging current produces the resistance of high line higher than threshold current, high stray inductance, high parasitic capacitance cause
The problem of frame losing.The present invention solves TYPE_C and relies on communication PD agreement communication in the case of large current charge of CC interface communication
Extremely the problem that charging system cannot normally work is caused..
