Embodiment
When digital electric equipment and PC are online, user's use original intention may be transfer files be not the charging demand, but promptly inserting the mode of promptly filling still can be when PC and mobile phone couples together, by USB_VBUS battery is charged, and battery electric quantity also compares under the sufficient situation, it is bigger to discharging and recharging the infringement of battery of plug USB_VBUS in the waste, particularly short time of battery charging and discharging number of times beyond doubt promptly to insert the mode of promptly filling, and has a strong impact on its useful life.
In order to address the above problem, embodiments of the invention provide a kind of intelligent charging method, use flow process that this method manages battery charge as shown in Figure 1, comprising:
In this step, when having detected the access of external charging power supply, need to determine earlier the type of external charging power supply, testing circuit as shown in Figure 2, USB_DP and USB_DM signal design weak pull-up resistor (as 125K Ω) respectively to VREG_5V, pull down resistor (as 375 K Ω) is to ground, the D+ of power supply adaptor and D-signal directly enter control chip by last pull down resistor, the 15K pull down resistor of USB_HOST (PC) is the USB code requirement, therefore when detecting by measuring ability module (GPIO or A/D), the CONTROL ASIC (control chip) of mobile phone has the external charging power supply, and when being the VREG_5V of legal range (legal range of general power supply is 4.5V to 5.5V), after time-delay after a while goes to tremble processing, read the state of USB_DP (D+) and USB_DM (D-).If its logic level assembled state is " 00 ", then the external charging power supply type is USB_VBUS; If its logic level assembled state is " 10 " then the external charging power supply type is CHARGER.
Externally charge power supply is under the situation of the CHARGER power supply in the legal range, and software unconditionally enables inner Charge Management process.If when the external charging power supply is a USB_VBUS power supply in the legal range, at first need to detect VBAT (battery) electric weight, enter step 102.
If step 102 power supply type is the USB_VBUS power supply of magnitude of voltage in legal range, detect the battery current electric quantity;
In this step, obtain the current VBAT electric weight of battery indirectly by detecting VBAT voltage, the detection method of battery electric quantity and cell voltage and corresponding relation are as shown in Figure 3, obtain battery capacity from the discharge curve respectively and be 5%, 25%, 50%, 75%, 100% o'clock corresponding voltage value, the corresponding relation of battery capacity and cell voltage is set, infers remaining electric weight in the current battery according to the magnitude of voltage that records.
In the embodiment of the invention, a charge threshold need be set at first, be standard with this charge threshold, determines whether and need charge.This threshold value can be a magnitude of voltage, also can be dump energy percentage, and existing is that 50% dump energy is that example describes with threshold value.
By A/D sample detecting VBAT electric weight, if battery electric quantity is lower than 50%, software unconditionally enables the Charge Management process, by the USB_VBUS power supply battery is charged when inserting USB_VBUS; Otherwise, enter step 103.
In this step, if battery electric quantity is not less than 50%, thinking the battery electric quantity abundance does not need charging, then refuses by the USB_VBUS power supply battery to be charged, but still can normally carry out by the transfer of data of USB_VBUS mouth.
Further, can send prompting to the user when refusal passes through the USB_VBUS power supply, as the screen pop-up window by data electronic products such as mobile phone, MP4, notify user's electric weight abundance, whether the inquiry user needs the power source charges by USB_VBUS; If the user still will charge, then issue the forced charge indication, pressure is charged to battery by the USB_VBUS power supply, can realize (as the short down closing key of pressing of off-mode, long by power up function to be different from for the forced-triggered button by the button that the data electronic product is set; Forced charge button design under the open state is more flexible, is decided according to the actual requirements) also can when ejecting the window of prompting electric weight abundance, provide option.
Embodiments of the invention also provide a kind of intelligent charger, and the structure of this intelligent charger comprises as shown in Figure 4:
Electric weight detection module 402 is used for detecting the battery current electric quantity when described type detection module 401 judges that power supply types are the USB_VBUS of magnitude of voltage in legal range;
Further, described electric weight detection module 402 also is used to be provided with the also charge threshold of storage battery;
Described charge management module 403 also is used for when the battery current electric quantity is lower than the charge threshold that presets, and by described USB_VBUS power supply battery is charged.
Further, described charge management module 403, also being used at described type detection module 401 detected power supply types is magnitude of voltage not during the USB_VBUS in legal range, the refusal charging; Or,
When power supply type is the CHARGER of magnitude of voltage in legal range, battery is charged by described CHARGER power supply.
