Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.Refer to Fig. 3, the invention provides a kind of portable power source with battery electric quantity measuring ability, the electricity of battery 20 can be shown in display module 23.Portable power source comprises voltage detection module 21, digital processing unit 22, display module 23, clock module 24 and control module 25.Wherein, the control of voltage detection module 21 response module 25, measures the voltage of battery 20, converts the voltage scale of battery 20 to set of number signal; Described digital signal is converted to charge value by digital processing unit 22, and preserves, until there is new numeral input; Described charge value shows by display module 23; Clock module 24 provides clock to voltage detection module 21 and control module 25; Control module 25, according to user's input and the state of portable power source, produces corresponding control signal, the opening and closing of control voltage detection module 21, digital processing unit 22 and display module 23;
Refer to Fig. 4, Fig. 4 is control flow chart of the present invention, specifically comprises step:
S101, portable power source starts charging, starts electric discharge or user's trigger switch button;
S102, control module inside arranges the timer T1 of a 50ms;
S103, judges that whether timer T1 is overtime, if overtime, enters step S104, otherwise continues to wait for;
S104, opens display module, and arranges counter J=0 in control module inside;
S105, cut-in voltage detection module and digital processing unit, carry out an electric power detection, voltage detection module converts the voltage equal proportion of battery-end to set of number signal, described digital signal is converted to corresponding information about power by digital processing unit, deliver to display module, shown by described information about power in display module, the counter J in control module adds 1;
S106, control module judges whether portable power source is in charged state, if so, enters step S108, otherwise enters step S107;
S108, control module inside arranges the timer T2 of a 2s;
S109, judges that whether T2 is overtime, if overtime, enters step S105, otherwise continues to wait for;
S107, judges whether counter J is less than 3, if so, enters step S108, not so enter step S110;
S110, closes display module;
Wherein, by described step S101 ~ S104, portable power source starts charging, electric discharge, or 50ms after user's trigger switch button, just carry out first time to battery electric quantity measure and show, now battery terminal voltage is stablized, and therefore measures and the numerical value that shows accurately can represent the electricity of battery;
By described step S105 ~ S109, after completing an electric power detection, the timer of a 2s is set, etc. described timer expiry, just cut-in voltage detection module and digital processing unit again, carry out again battery voltage detection and information about power renewal, be delayed 2s between described twice electric power detection, save power consumption;
Described step S106 judges whether portable power source is in charged state, if be in charged state, then repeatedly battery electric quantity is detected with the time interval of 2s always, be convenient to user and grasp charging progress at any time, because portable power source is in charged state, the impact of described battery electric quantity detection and the power consumption of display institute is little;
Described S107 judges whether counter J is less than 3, if not, then close display module, therefore, after portable power source discharges initial or user's trigger switch button, with the time interval of 2s, after 3 detections are carried out to battery electric quantity, no longer do electric power detection and display, save power consumption further;
Timer T1 is not limited to 50ms, and timer T2 is not limited to 2s, and counter J is also not limited to technology to 3 times, can make various change according to actual needs;
Above-mentionedly only the specific embodiment in the present invention to be illustrated; but can not as protection scope of the present invention; everyly to zoom in or out according to the change of the equivalence done by design spirit in the present invention or amendment or equal proportion, all should think and fall into protection scope of the present invention.
