Description
Technical field
The present invention, which is disclosed, detects battery method in place in a kind of EC programs, be related to field of battery management, specifically
Detect the method that battery whether there is in the EC programs of portable set.
Background technology
In a portable device, Intelligent lithium battery and intelligent charger are widely used.The discharge and recharge of Intelligent lithium battery
The upload of journey and battery information, is all that embedded controller EC is controlled.EC is embedded controller contracting
Write, for perform specified independent control function and with complex process data capability control system.By embedded microelectronics skill
Art chip is come the electronic equipment or device that control, so that the device can complete monitoring, the various automations such as control
Processing task.EC is typically connected by SMBUS buses with Intelligent lithium battery and intelligent charger, and uses lpc bus and main frame
Communicated.
Under operating system, the state that the icon of battery can also exist according to battery is shown, and Intelligent lithium battery
Charging process is carried out under conditions of battery presence, and after battery is pulled out, battery has flag bit clearing, it is impossible to carry out
The operation of battery.And the charging process of Intelligent lithium battery is controlled by EC, charge step is broadly divided into four-stage：Wake-up is filled
Electricity, be pre-charged, charge normal and be full of.There is flag bit whether to judge battery generally according to battery, and battery whether there is
To battery charging and discharging and other on it is battery-operated judge it is particularly significant.The present invention provides detection battery in a kind of EC programs and existed
The method of position, to battery in EC programs with the presence or absence of detecting, prevents the problems such as over-discharge occurs in battery, can play anti-again
The only effect of battery overheat.
The content of the invention
There is provided battery side in place is detected in a kind of EC programs with problem in view of the shortcomings of the prior art by the present invention
Method, the not only display of battery charging and discharging flow and battery under system provides condition, can also prevent battery from over-discharge occur
The problems such as, it can play a part of preventing battery from overheating again.
Concrete scheme proposed by the present invention is：
Battery method in place is detected in a kind of EC programs, the both end voltage of inside battery thermistor is obtained, two ends electricity is judged
Whether pressure exceedes overtemperature protection voltage, exists no more than then battery, is otherwise detected by way of communication, if communicating into
Work(, represents that battery is present, otherwise battery has flag bit clearing, repeats to read the both end voltage of inside battery thermistor
Operation, proceed judge.
When judging that both end voltage is no more than overtemperature protection voltage, battery overheat flag is reset, otherwise passes through communication
Mode detected, is to judge that adapter whether there is if battery overheat flag is zero and communicated successfully, in the absence of then opening
Dynamic battery overheat protecting flow, otherwise judges whether that battery overheat flag is 1 and communicated successfully, is that then battery has mark
Position, otherwise there is flag bit clearing in battery, repeat read inside battery thermistor both end voltage operation, continue into
Row judges.
Described method, the thermistor output end of battery is connected with EC ADC pins, calculated according to hardware circuit
The value of Thermal protection voltage.
Described method, the voltage at thermistor two ends is obtained using analog-digital converter.
Described method, is detected by way of SMBUS bus communications.
Usefulness of the present invention is：
The present invention provides a kind of detection battery method in place in EC programs, obtains the both end voltage of inside battery thermistor,
Judge whether both end voltage exceedes overtemperature protection voltage, exist no more than then battery, otherwise detected by way of communication,
If communicating successfully, represent that battery is present, otherwise battery has flag bit clearing, repeat to read inside battery thermistor
The operation of both end voltage, proceeds to judge；
It can prevent battery from over-discharge etc. occur and asking to battery in EC programs with the presence or absence of detecting using the inventive method
Topic, can play a part of preventing battery from overheating again.
Brief description of the drawings
Fig. 1 the inventive method schematic flow sheets.
Embodiment
The present invention provides a kind of detection battery method in place in EC programs, obtains the two ends electricity of inside battery thermistor
Pressure, judges whether both end voltage exceedes overtemperature protection voltage, exists no more than then battery, is otherwise examined by way of communication
Survey, if communicating successfully, represent that battery is present, otherwise battery has flag bit clearing, repeat to read inside battery temperature-sensitive electricity
The operation of the both end voltage of resistance, proceeds to judge.
With reference to accompanying drawing and specific implementation, the present invention will be further described.
Using the inventive method, the voltage inside battery thermistor two ends is obtained using analog-digital converter, two ends are judged
Whether voltage exceedes overtemperature protection voltage, exists no more than then battery, is otherwise examined by way of SMBUS bus communications
Survey, if communicating successfully, represent that battery is present, otherwise battery has flag bit clearing, repeat to read inside battery temperature-sensitive electricity
The operation of the both end voltage of resistance, proceeds to judge.
, can be by the voltage at thermistor two ends when the above method is implemented, the corresponding temperature of acquisition of tabling look-up, if setting electricity
Pond temperature needs to carry out overtemperature protection to battery when exceeding certain temperature, then now the voltage at thermistor two ends is just protected for overheat
Voltage is protected, the thermistor output end of battery can be also connected with EC ADC pins, overtemperature protection electricity is calculated according to hardware circuit
The value of pressure；
Then judge whether both end voltage exceedes overtemperature protection voltage using the inventive method, during no more than overtemperature protection voltage,
Battery overheat flag is reset, otherwise detected by way of SMBUS bus communications, if battery overheat flag is zero
And communicate successfully, it is to judge that adapter whether there is, in the absence of battery overheat protecting flow is then started, otherwise judges whether electricity
Pond overheat flag is 1 and communicated successfully, is that battery has flag bit, otherwise battery has flag bit clearing, repeats
The operation of the both end voltage of inside battery thermistor is read, proceeds to judge.
The flow of above-mentioned startup battery overheat protecting can write program according to course diagram, and when battery is overheated, startup is fallen
Timing shutdown process, and pointed out by indicator lamp, to start battery protective effect.
So can prevent battery from occurring excessive to battery in EC programs with the presence or absence of detecting using the inventive method
The problems such as electric discharge, it can play a part of preventing battery from overheating again.
