Abstract
The present invention provides a kind of method that lithium battery information is shown, it is related to the Intelligent lithium battery systems technology of notebook EC (Emebedded Control) control system, the present invention is controlled by lithium battery voltage pin, one energization pins of lithium battery are directly connected on a GPIO port of external MCU controller, can determine whether current lithium battery online information by detecting this GPIO port information.
Description
Technical field
The present invention relates to the Intelligent lithium battery systems technologies of notebook EC (Emebedded Control) control system, especially
It is related to a kind of method shown based on notebook lithium battery information.
Background technique
Currently, the lithium battery for taking down notes this product all uses Intelligent lithium battery, i.e. inside battery has special MCU controller to go
The charge and discharge of lithium battery are controlled, while acquiring the every terms of information of lithium battery, all information all follow SBS1.1 specification.External
MCU controller, such as EC controller can be logical by the MCU inside SMBUS either I2C and Intelligent lithium battery according to this specification
Letter, obtains current lithium battery information, is then transferred to operating system, and computer host computer shows that program can pass through current lithium battery
Information show that lithium battery is online or not presence, since computer host computer procedure is to obtain lithium battery letter by EC
Breath, then produces again and gives operating system, then show, if any one link goes wrong wherein, host computer is just
It cannot show that information or the display reaction speed of lithium battery presence or absence are slow, be unfavorable for user or application program goes to obtain in real time
Information existing for lithium battery.
For the software detection and display of lithium battery, there are two types of conventional ways, battery producer specially design one it is dedicated
DETECT pin realized to design, another kind is exactly software judged by the information transmitted on reading I2C lithium battery
The implementation method of linear state.
Summary of the invention
In view of the above problems, the invention proposes a kind of method shown based on notebook lithium battery information, it can be quick
Response lithium battery presence information simultaneously sends operating system to.
Lithium battery presence information is designed as being controlled by lithium battery voltage pin, by a power supply of lithium battery
Pin is directly connected on a GPIO port of external MCU controller, can determine whether currently by detecting this GPIO port information
Lithium battery online information.It is illustrated in fig. 1 shown below, as long as PACK has voltage, BAT_ID can be detected the presence of lithium battery.It is external
MCUEC controller can confirm the presence of lithium battery by the low and high level of this pin.
In terms of software design, external MCU is after detecting lithium battery online information, in such a way that system SCI is interrupted
Go notice operating system lithium battery presence information.
Particular content is as follows：
EC detects the height of its GPIO port BAT_ID level, can judge the movement of lithium battery inserted or pull out, and leads to
It crosses after detecting this movement, EC notifies operating system in such a way that SCI is interrupted, and can enter lithium battery plug event letter first
Number, then going judgement is to extract or be inserted into, if insertion lithium battery can also go control charging action by detecting its information about power,
Then EC sends information to operating system by SCI system break function, leads to immediately after operating system real-time reception to this information
It crosses calling lithium battery information display program and shows battery presence information.
Detailed description of the invention
Fig. 1 is lithium battery interface circuit schematic diagram.
Specific embodiment
More detailed elaboration is carried out to the contents of the present invention below：
As long as BAT_ID can be detected the presence of lithium battery as shown, PACK has voltage.External MCU EC controller
The presence of lithium battery can be confirmed by the low and high level of this pin.
EC detects the height of its GPIO port BAT_ID level, can judge the movement of lithium battery inserted or pull out, and leads to
Cross detect this movement after, EC can SCI interrupt by way of notify operating system, software design as shown in following codes,
Lithium battery plug event functions can be entered first, then going judgement is to extract or be inserted into, if insertion lithium battery can also pass through inspection
It surveys its information about power and goes control charging action, then EC sends information to operating system, operation system by SCI system break function
Immediately by calling lithium battery information display program to show battery presence information after system real-time reception to this information.
When plug lithium battery, system can cracking hair mirror lithium battery online information, even if lithium battery and outer
The SMBUS communication abnormality of MCU is set, host computer also can correctly show lithium battery online information.
Claims (5)
