Embodiment
In order to solve terminal charge heating and the slow problem of charging in prior art, the invention provides a kind of charger, terminal and charging method.
The present invention can adopt quick charge mode between charger and terminal, quick charge mode avoids using the built-in charging chip of terminal, then use the external charging chip in charger, reduce the loss of electric current in transmitting procedure, and then reduce terminal temperature in charging process, improve the power output of circuit, thereby shortened the charging duration of terminal.
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, does not limit the present invention.
The invention provides a kind of charger, as shown in Figure 2, Fig. 2 is the structure chart of charger according to an embodiment of the invention.
This charger comprises transformer 210 and external charging chip 220.
Transformer 210, for exporting the first electric parameter to external charging chip 220.
External charging chip 220, obtains the second electric parameter for the first electric parameter is carried out to transformation, exports the second electric parameter to terminal, carries out quick charge for terminal.
Particularly, electric parameter comprises electric current and voltage.The value of the first electric parameter is greater than the value of the second electric parameter.The value of the second electric parameter is the required electric parameter value of terminal, that is to say deboost value and the Limited Current value of end cell, and for example, in the time of charging, the deboost value of lithium ion battery is that 4.2V, Limited Current value are 4A.Further, first export the first magnitude of voltage by transformer 210, then be second voltage value by external charging chip 220 by this first magnitude of voltage transformation.Wherein, second voltage value is the required magnitude of voltage of terminal, by regulating the size of the first magnitude of voltage, controls the pressure reduction between the first magnitude of voltage and second voltage value, and then makes external charging chip 220 output current values equal the required current value of terminal.
In one embodiment, charger of the present invention also comprises controller 230.Be illustrated in figure 3 the structure chart of charger according to another embodiment of the present invention.
Controller 230, for judging whether terminal carries out quick charge, if so, control transformer 210 and external charging chip 220 carry out quick charge for terminal, otherwise control transformer 210 charges for terminal.
External charging chip 220, under the control at controller 230, the first electric parameter transformation that transformer 210 is exported is the second electric parameter, and exports to terminal.
Transformer 210, under the control at controller 230, exports the first electric parameter to external charging chip 220, or to terminal output the 3rd electric parameter.
Particularly, the value of the 3rd electric parameter is output voltage values and the current value that meets national standard.As: magnitude of voltage is that 5V, current value are 2A.The 3rd electric parameter can not dumb terminal battery, need to pass through the built-in charging chip transformation of terminal, is the second required electric parameter of terminal by the 3rd electric parameter transformation.But, those skilled in the art should know, the built-in charging chip of terminal is in the time carrying out transformation to the 3rd electric parameter, can be because the pressure reduction between the magnitude of voltage in magnitude of voltage and the second electric parameter in the 3rd electric parameter is less, cause transformation process loss larger, cause terminal heating, and in transformation process, be difficult to current value to be promoted to the required current value of terminal, cause charging duration longer.
Therefore, charger can provide fast charge mode for terminal, and the implementation of quick charge is: direct access is set in terminal, as, wire.In the time being terminal charge, this direct access is connected with the external charging chip 220 in charger.The first electric parameter that transformer 210 is exported is adjustable, make the both sides of external charging chip 220 obtain larger pressure reduction, thereby make external charging chip 220 needed the second electric parameter of outlet terminal easily, and directly this second electric parameter is outputed to end cell, the problem that the terminal charge time is long and terminal is generated heat of avoiding built-in charging chip transformation to cause.
More specifically, controller 230 judges whether terminal can carry out quick charge, can realize by the mode that sends message to terminal.Controller 230 sends handshaking information to terminal; Judge whether terminal returns to the response message of shaking hands, wherein, the response message of shaking hands comprises the numerical value for the second electric parameter of quick charge; If so, judge that terminal carries out quick charge; Otherwise judgement terminal is not carried out quick charge.Further, can be set the first stand-by period, if do not receive the response message of shaking hands within the first stand-by period, judge that terminal do not carry out quick charge.
Waiting for the shaking hands when response message of terminal, adopt the 3rd electric parameter, be terminal charge.
In one embodiment, when receiving the shaking hands after response message of terminal, can also send the ready information of charging to terminal, for informing that terminal can carry out quick charge.When receiving the ready response message of charging of terminal, start to carry out quick charge.Otherwise adopting the 3rd electric parameter is terminal charge.Further, can be set the second stand-by period, if within the second stand-by period, not receive the ready response message of charging that terminal sends, adopting the 3rd electric parameter is terminal charge.
In one embodiment, in the time carrying out quick charge for terminal, controller 230 also for: every the default time period, to terminal send link information; Whether the connection response message of returning for terminal, judge for connecting the reception of response message overtimely, and if so, stopping charging or adopting the 3rd electric parameter is terminal charge, otherwise continues to send link information to terminal, until charging finishes.
