However, since the battery voltage of the mobile terminal will change with the load of the mobile terminal system, when the load of the mobile terminal system suddenly increases, the battery voltage will decrease accordingly, and when the load decreases, the battery voltage will rise. During the phone call, the battery power obtained b

Embodiment 2

[0121] Embodiment 2: The mobile terminal system has entered a low power consumption mode, and the mobile terminal is in a non-charging state.

[0122] Such as image 3 As shown in the middle 2 branch, the user receives an operation command to wake up the screen, wakes up the mobile terminal system to enter the high power consumption mode, records the current time of the mobile terminal system as T02, and obtains that the time length of the mobile terminal system in the low power consumption mode is T0=T02-T1. At the same time, control and start the ADC in the mobile terminal system to collect the current voltage of the battery, and obtain the current collected power of the battery through the voltage and power corresponding table, which is denoted as C02; at the same time, calculate the theoretical maximum power consumption of the battery within the time T0 , recorded as Q00.

[0123] Comparing the C02 with C1, if C02>=C1, since the battery power must not increase when the m...

Embodiment 3

[0158] Embodiment 3: The mobile terminal system is in a high power consumption mode, and the mobile terminal is in a charging state.

[0159] Such as image 3 As shown in the middle branch 3, when it is not detected that the mobile terminal system enters the low power consumption mode within the predetermined time, the ADC is triggered to collect the current voltage of the battery, and the current collection of the battery is obtained through the voltage-power correspondence table Electricity, denoted as M2.

[0160] The control compares the M2 with the C1, since it is charging, the battery power cannot be reduced, so the battery power is updated only when the collected power is greater than the previously recorded original power. That is, if M2C1, control to update the battery power to be C1+1, that is, control to update the original power C1=C1+1. The updated battery power is distributed to each functional module of the mobile terminal system, and the timer is restarted at...

Embodiment 4

[0170] Embodiment 4: The mobile terminal system is in a high power consumption mode, and the mobile terminal is in a non-charging state.

[0171] Such as image 3 As shown in branch 4, when the timer times out, the ADC is triggered to collect the current voltage of the battery, and the current collected power of the battery is obtained through the voltage and power correspondence table, which is recorded as M02.

[0172] The control compares the M02 with C1, if M02>=C1, since the battery power must be reduced when the mobile terminal is in the non-charging state, it can be judged that M02 is definitely not the current real power of the battery, and the battery power is maintained at the original level at this time The power C1 is not updated, that is, the current real power of the battery is the original power C1 by default. If the M02

Abstract

The invention discloses a method for mobile terminal to update the electric quantity of a battery and the mobile terminal. The method comprises the steps that the battery voltage is collected when the mobile terminal system is started, and the original electric quantity of the battery is obtained through a pre-established voltage and electric quantity conversion table; the current battery voltage is collected to obtain the current collected electric quantity of the battery, and theoretical charging-discharging electric quantity of the battery of the mobile terminal is calculated according to a collection time interval; the collected electric quantity is compared with the original electric quantity, and whether the collected electric quantity is the real current electric quantity of the battery or not is judged in combination with the theoretical charging-discharging electric quantity; and if not, the real current electric quantity of the battery is estimated according to the theoretical charging-discharging electric quantity; and the original electric quantity is updated to the real current electric quantity of the battery and distributed to each functional module of the mobile terminal system. The method has the advantages that the real current electric quantity of the battery is accurately obtained through a battery charging-discharging pre-estimation mechanism, thereby effectively avoiding abnormal fluctuation phenomena from occurring when the electric quantity of the battery is updated by the mobile terminal.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a method for updating battery power of a mobile terminal and the mobile terminal. Background technique [0002] With the development of mobile communication technology and the continuous improvement of people's living standards, the use of various portable mobile terminals such as mobile phones has become more and more popular, and has become an important part of people's daily life. [0003] Current portable mobile terminals are generally powered by batteries, and it is necessary to update the battery power status in real time and notify each functional module of the mobile terminal; the battery power update method in the prior art is: collect the voltage of the battery, and pass the corresponding relationship between the voltage and power Determine the current charge level of the battery and update the charge level. However, because the battery voltage of the mobile terminal wi...
