Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
First embodiment
As it is shown in figure 1, the charging circuit of the embodiment of the present invention, described charging circuit and a charger connect, described charging circuit includes:
Connecting interface, including multiple connection ends, each described connection end is connected with a signal output apparatus of described charger respectively.
Here, connect interface and include that multiple connection end, each connection end are connected with the signal output apparatus of charger respectively, thus are accessed smoothly by charger, to complete charging.
Mu balanced circuit, connects with described the first connection end being connected end, for when connect with described first the corresponding connection of end signal output apparatus output for unstable magnitude of voltage time, connect the voltage stabilization at end by described first at the first preset voltage value.
For nonstandard charger, the positive signals DP circuit of numeral is unsettled with numeral negative signal DM circuit, and output is all unstable magnitude of voltage, thus cannot nonstandard charger and Fructus Mali pumilae charger be distinguished.Here, mu balanced circuit is passed through, it is possible to by the voltage stabilization of a signal output apparatus of nonstandard charger at the first preset voltage value such that it is able to determine access is nonstandard charger.
Wherein, in order to guarantee to accurately distinguish nonstandard charger and Fructus Mali pumilae charger, first preset voltage value should be set as the magnitude of voltage being different from Fructus Mali pumilae charger under corresponding circuits, is typically set to that the first preset voltage value is less than the magnitude of voltage under Fructus Mali pumilae charger corresponding circuits.
First charging control circuit, it is connected interface with described respectively and battery to be charged connects, for obtaining the magnitude of voltage at each described connection end, when determining that at described first connection end be described first preset voltage value, when the magnitude of voltage at other connection ends in addition to described first connects end is labile state, send the first current controling signal using preset security electric current that described battery to be charged is charged, make described charger according to described first current controling signal, described battery to be charged be charged.
Here, if being the first preset voltage value at the first connection end, other magnitudes of voltage connected at ends are labile state, then can determine that access is nonstandard charger, uses less safe current to be charged.
The charging circuit of the embodiment of the present invention, by increasing mu balanced circuit, can be by the voltage stabilization of a signal output apparatus of nonstandard charger the first preset voltage value (being different from Fructus Mali pumilae charger magnitude of voltage under this signal output apparatus), thus nonstandard charger and Fructus Mali pumilae charger can be recognized accurately, and the nonstandard charger only meeting above-mentioned voltage conditions just uses less safe current to charge, solve traditional method and Fructus Mali pumilae charger is identified as nonstandard charger, cause charging current the lowest, charging rate is the slowest, the fan-out capability of Fructus Mali pumilae charger can not be made full use of, reduce the charging rate of mobile phone, the problem that have impact on Consumer's Experience.
