Embodiment
The embodiment of the present invention provides the method for the calculating initial quantity of electricity shown in a kind of Fig. 1, with the initial quantity of electricity that accurate display terminal is shown after battery plug operation, so-called initial quantity of electricity (initialization also known as initialization electricity, electricity) refers to terminal and obtains and the battery electric quantity shown in start-up phase, the dump energy of the percents of such as terminal screen upper right side display.Described method is applicable to smart mobile phone, PDA (PersonalDigitalAssistant, personal digital assistant or panel computer), the battery powered terminal of any needs such as portable communication appts, Intelligent bracelet can also be applicable to, the Wearable be embedded in the clothing component such as clothes, jewellery.
As shown in Figure 1, the method for described calculating initial quantity of electricity comprises:
Step 11: obtain terminal its battery of shut-down-phase dump energy and preserve.
For the mobile phone of MTK platform, the dump energy of battery is obtained by the charging thread of terminal.The charging that charging thread primary responsibility controls battery and the process of powering for terminal, and whether the thread that charges needs the power supply environment judging battery abnormal after unlatching, described power supply environment comprises at least one in the Current Temperatures of battery, open-circuit voltage and battery ID (Identity, identification code).If power supply environmental abnormality, then stop power supply; If power supply environment is normal, then start power supply.
Current charging thread calculates the dump energy of one-shot battery in (such as 10 seconds) every predetermined period, the dump energy preserved is needed to be multiple (value is close, identical or different), this obviously can increase the burden of the operating system of terminal undoubtedly, therefore the embodiment of the present invention only preserves the dump energy of the battery of shut-down-phase, to reduce the burden of operating system.
The dump energy of described battery can the open-circuit voltage of reference battery under open-circuit condition (OpenCircuitVoltage is called for short OCV) be index.In the process of operating system, there is internal resistance in the device run due to terminal, and the open-circuit voltage of battery is difficult to Obtaining Accurate.Consider in shut-down-phase, LCD (the LiquidCrystalDisplay of terminal, liquid crystal display) etc. the larger device of power consumption closed, therefore the embodiment of the present invention chooses the open-circuit voltage of the battery of shut-down-phase, can improve the accuracy of described residual capacity measurement further.
In addition, being different from prior art is stored in RTC by the dump energy of battery, battery is stored in the flash memory (FlashMemory) of terminal at the dump energy of shut-down-phase by the embodiment of the present invention, this is a kind of nonvolatile memory based on flash memory, though battery pulled out or stop for terminal power after the data (dump energy) be stored in wherein also can not lose.
Step 12: when terminal enters start-up phase by shut-down-phase, judges whether the battery of current battery of powering for terminal and shut-down-phase is same.
Namely judge whether the battery of start-up phase and the battery of shut-down-phase are same.If same, then perform step 13; If not same, then perform step 14.
