Shown in figure 2, it is the flow chart of the charging current control method preferred embodiment of electronic installation 1 of the present invention.In the present embodiment; the charging rate that the method can be accelerated by heightening the charging current of charger 2 electronic installation 1 reaches the object that reduces the charging interval, and the temperature that reduces electronic installation 1 by turning down the charging current of charger 2 reaches the object of the battery of protection electronic installation 1.
Step S201, initialization module 101 is set a charging current table is set, and this charging current is arranged and shows to be kept in power management chip 11.In the present embodiment, described charging current arranges table for storing the charging current of different order of magnitude of charger 2, for example, by charging current can be set to 300mA, 600mA, 900mA .... and the different current class value such as 1500mA.
Step S202, initialization module 101 connects charger 2 and electronic installation 1, and charger 2 and external power source 3 are connected.Described external power source 3 is a kind of mains supply, and it provides charge power supply for electronic installation 1.
Step S203, charge control module 104 is controlled charger 2 electronic installation 1 is charged.Do not regulate the charging current of charger 2 user before, charge control module 104 is controlled charger 2 and under initial charge current, electronic installation 1 is charged, and for example initial charge current is set to 600mA.
Step S204, button judge module 102 judges whether electronic installation 1 receives push button signalling.If electronic installation 1 is to push button signalling, flow performing step S205; If electronic installation 1 is to receive push button signalling, flow process is returned to step S203.
Step S205, button judge module 102 judges that whether push button signalling is from key, if push button signalling from key, flow performing step S206; If push button signalling is not from key, flow process turns to step S208.
Step S206, button judge module 102 judges that according to the degree of strength of push button signalling this push button signalling is long by signal or short in signal.If push button signalling is long by signal, flow performing step S207; If push button signalling is short in signal, flow process turns to step S212.
Step S207, charge control module 104 is opened display screen 12 and is controlled electronic installation 1 and start shooting and use for user.
Step S208, button judge module 102 judges that whether push button signalling is from volume key.If push button signalling is from volume key, flow performing step S209; If push button signalling is not from volume key, flow process turns to step S203.
Step S209, button judge module 102 judges that push button signalling is that volume increases signal or volume reduces signal.If being volume, push button signalling increases signal, flow performing step S210; Reduce signal if push button signalling is volume, flow process turns to step S211.
Step S210, current regulating module 103 arranges table control charger 2 according to the charging current in power management chip 11 and heightens charging current.In the present embodiment, in the time that user need to carry out quick charge to electronic installation 1, if the original charging current of charger 2 is 600mA, user increases key the charging current of charger 2 is heightened to 900mA from 600mA by pressing volume, thereby reaches the object of accelerating the charging rate of electronic installation 1 and reduce the charging interval.
Step S211, current regulating module 103 current regulating module 103 arrange table control charger 2 according to the charging current in power management chip 11 and turn down charging current.In the present embodiment; when ambient temperature is too high while causing electronic installation 1 overheated; user turns down 300mA by pressing volume minimizing key by the charging current 600mA of charger 2; thereby minimizing charging current reduces the temperature of electronic installation 1, reach the object of the battery of protection electronic installation 1.
Step S212, charge control module 104 is controlled the charged state of display screen 12 display electronics assemblies 1, for example, shows the charged electrical flow graph of reflection electronic installation 1 charged state on display screen 12.
Step S213, charge control module 104 judges whether the electric weight of electronic installation 1 is full of.If the electric weight of electronic installation 1 is full of, flow performing step S214; If the electric weight of electronic installation 1 is not full of, flow process turns to step S203.
Step S214, charge control module 104 is controlled charger 2 electronic installation 1 is stopped to charging, prevents from for a long time electronic installation 1 being accessed the battery that causes the excess Temperature of electronic installation 1 in external power source 3 and damage electronic installation 1.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to above preferred embodiment, those of ordinary skill in the art should be appreciated that and can modify or be equal to the spirit and scope that replacement should not depart from technical solution of the present invention technical scheme of the present invention.
