Description

The bearing calibration of battery remaining power
[technical field]
The invention relates to a kind of method of correction of residual capacity, and the particularly bearing calibration when not enough relevant for a kind of residual capacity of battery.
[background technology]
The electric system of general electronic installation, its main power supply comprises AC power supplies and DC power supply.AC power supplies is provided (for example source power supply of voltage 110V or 220V) by external power company, and AC power supplies converts lower DC voltage (for example 3.7V or 5V) to via a-c transducer (AC Adapter), uses for the required electric power of system load element.In addition, the DC power supply is provided (for example 3.6V or 5V) or outside DC voltage to be provided by intrasystem main battery, and the DC power supply also can convert the required electric power of system load element to via direct current transducer (DC Converter), is suitable for the fixed voltage (for example 5V or 3.3V) of system load element running with arrival.With the mobile phone is example, its inner microprocessor, internal memory, display, and perhaps peripherals all can be considered the some of system load element.
In order to allow the user understand the power state and the battery remaining power of present main battery, demonstrate battery remaining power according to the variation of battery capacity in the mode of number percent on the screen of main system.When the electric weight of battery charges to state of saturation by external power source, the capacity of battery is set at 100%, and when the electric weight subcritical value of battery for example 10% time, the electric weight of expression battery is about to exhaust, can't provide enough voltage, electric current to use, immediately the powered-down or the action of charging for main system.Yet the mode of existing counting cell residual capacity is according to the resulting scaled value of the state of cell output voltage, and estimating battery residual capacity between the height change in voltage is to allow the user can know the power state of learning battery.; the mode of this counting cell residual capacity is also unreliable; external uncertain factor is for example when when start or conversation under the demand of relatively large electric current or under the state of battery electric quantity deficiency; when if the output voltage of battery is unstable; be easy to judge by accident the residual capacity in outage pond; cause system misoperation and the data loss, or cause battery over-discharge and the loss battery life.Therefore, under the influence of all uncertain factors, how preventing the residual capacity in locking system erroneous judgement outage pond, is the primary problem of anti-making mechanism.
[summary of the invention]
The object of the present invention is to provide a kind of bearing calibration of battery remaining power,, can not produce phenomenons such as undesired shutdown to guarantee system in order to revise the residual capacity of battery.
Another object of the present invention is to provide a kind of bearing calibration of battery remaining power,, can not run off with the data of guaranteeing system so that battery can start shooting when the threshold capacity smoothly, and then enters standby picture smoothly.
For reaching above-mentioned purpose of the present invention, the present invention proposes a kind of bearing calibration of battery remaining power, comprise that the voltage transitions with a battery becomes a corresponding battery remaining power, judges the capacity status of a battery, and revises battery remaining power with the capacity conversion table of a battery.
For reaching above-mentioned purpose of the present invention, the present invention proposes the method for a kind of anti-locking system erroneous judgement outage pond residual capacity, at first start the power supply of a system and judge the voltage of a battery, when the voltage of battery during greater than a cut-in voltage, so that system enters power on mode.Then, the voltage transitions of battery is become a battery remaining power, and the capacity status of judgement battery, when the capacity of battery during greater than a threshold capacity, enter holding state, and when the capacity of battery during less than the threshold capacity, revising or inserting battery remaining power makes it more than or equal to the threshold capacity, enter after the standby mode state of battery electric power displaying again, the power state of electrolytic cell that allowed the user afterwards.
Therefore, the present invention judges the voltage in outage pond or the residual capacity in erroneous judgement outage pond to avoid system by accident because of external uncertain factor, and then causes danger such as undesired shutdown or data loss by revising the residual capacity of battery.
[description of drawings]
Fig. 1 is the flow diagram of bearing calibration of a kind of battery remaining power of a preferred embodiment of the present invention.
[embodiment]
Please refer to Fig. 1, it is the flow diagram of bearing calibration of a kind of battery remaining power of a preferred embodiment of the present invention.At first start the power supply of a system, for example press the power switch of system, with the required operating voltage of the load elements that internal system is provided, and the power source of load elements for example converts direct voltage source (for example 3.7V or 5V) by outside source power supply to through the AC converter, can directly start shooting.In addition, when the power source of load elements was the stored electric weight of battery, under the demand that makes relatively large electric current when the start, system can start shooting smoothly, and the present invention designs an anti-making mechanism.Whether step 1 as shown in Figure 1, the voltage of earlier judging battery greater than threshold voltage (threshold voltage), can be with the electric weight of guaranteeing battery greater than a threshold capacity, and 100mAh for example, and be unlikely to produce the phenomenon of battery over-discharge.When the voltage of battery is less than or equal to threshold voltage, under the operating voltage of the load elements that can't reach system, incite somebody to action not open system, to avoid the load elements upset operation.Secondly, when the voltage of battery during, system is entered in the power on mode, shown in step 2 greater than threshold voltage.
Voltage that it should be noted that battery this moment may cause after the system boot in the voltage height instability that forces battery in a flash because of the influence of uncertain factors such as electric current increase that starts, and the residual capacity of preestimating battery makes a mistake.Therefore, step 3 as shown in Figure 1 when the voltage of battery converts the residual capacity of battery to according to a conversion table, is necessary to revise according to the load condition of the load condition of actual current or voltage the residual capacity of battery.
For example, step 4 as shown in Figure 1, the capacity status of judgement battery, for example when the electric current of battery is heavy duty (heavy loading), during for example more than or equal to 20mA or other empirical value, can influence the correct magnitude of voltage in system erroneous judgement outage pond, and make the residual capacity of battery incorrect.Therefore, system can revise the residual capacity of battery according to the capacity status of battery, if, then insert battery capacity, and enter standby mode, if not, then revise battery capacity, and on the screen of system, demonstrate battery remaining power in the mode of number percent according to the variation of battery capacity, as step 5.
Secondly, for avoiding system's factitious shutdown in start process, and cause danger such as data loss, when the storage electric weight of battery is near threshold capacity (threshold capacity), also must revise the residual capacity of battery according to current loading state or voltage status.If when the capacity of battery was judged as near the threshold capacity, the residual capacity that should revise battery made it greater than the threshold capacity, so that system directly enters a standby mode, and the data of finishing is maintained secrecy definite.Waiting system enters after the standby mode, and message such as battery electric power displaying deficiency can not run off because of power breakdown suddenly to guarantee data again.
Hence one can see that, the bearing calibration of the disclosed battery remaining power of the present invention, can apply in the portable electron device, devices such as mobile phone, intelligent mobile phone (smart phone), PDA(Personal Digital Assistant) for example, even when the threshold capacity, also system is started shooting smoothly, and enter the standby picture after the start with the storage electric weight of guaranteeing battery, and can show signals such as power shortage, the power state of electrolytic cell that allowed the user.So, by revising the residual capacity of battery, judge the voltage in outage pond or the residual capacity in erroneous judgement outage pond to avoid system by accident because of external uncertain factor, and then cause danger such as undesired shutdown or data loss.
