How to use the Demo Application
- This utility has to be used with bq2084 gas gauge.
Check Battery Info
In order to retrieve the current battery information, please click the “Check Battery Info” and battery information will be refreshed as current status.
- a.Battery Temperature.
- b.Battery Current.
- c.Battery Voltage.
- d.Battery Status for Charge or Discharge.
- e.Battery Status for Remaining capacity percent.
- f.Battery remaining life time.
- g.Battery Alarm Flag.
- h.Battery Cycle Count：After battery fully charge and fully discharge one time, the cycle count will add 1.(As the picture you can see, cycle count is 12, that means the battery has fully charged 12 times and fully discharged 12 times)
Note 1:
The battery control IC will protect the battery base on the preset threshold value.
Please download file from above “Battery Data Flash Info” for further preset threshold information.
- Over Charged:
Threshold = Full Charge Capacity + Maximum Over Chg.
The Over Charged and Terminate Charge warnings from Battery Alarm status will appear “Yes” when the value of full charge capacity + maximum over chg is greater than the set value of threshold and the charge action will be terminated.
- Over Temperature:
The Over Temperature and Terminate Charge / Terminate Discharge warnings from Battery Alarm status will appear “Yes” when the value of full charge capacity + maximum over chg is greater than the set value of threshold and the charge / discharge action will be terminated.
For Charge Mode: Threshold = Chg Suspend Temp Hi (Ref, Battery Data Flash Info)
For Discharge Mode: Threshold = Over Temp Dsg (Ref, Battery Data Flash Info)
Note 2:
The value of the “Current” from the Battery Info may appear in positive or negative value depending on the Charge / Discharge mode.
Setup Long Time Monitor
After click the “Battery Long Time Monitor” button, user will enter the Long Time Monitor setup dialog box to configure the parameters for the battery event log.
- A.User temperature Threshold: User can designate the preferred threshold value. The overheating event will be recorded in batterylog.txt once the battery temperature has exceeded the set threshold value.
- B.“New temperature threshold value” will appear in RED C after clicked the “Apply”.
- D.The Over temperature warning will appear as shown below when the action of “Run with user temperature threshold …” has been activated and exceeded the temperature threshold.
- E.User Capacity(%) Threshold: User can designate the preferred threshold value. The low capacity event will be recorded in batterylog.txt once the battery capacity has been below the set threshold value.
- F.“New capacity threshold value” will appear in RED G after clicked the “Apply”.
- H.The low capacity warning will appear as shown below when the action of “Run with user capacity threshold …” has been activated and below the capacity threshold.
- I.The Battery Long Time Monitor will set to refresh & record the monitor values after the set interval value.
- J.The computer will shut down when the action of “Shutdown automatically,…” has been active and below the capacity setting value(RED K).
- L.Activate the Battery Long Time Monitor (RED L) after complete the parameters and the event log will be saved as batterylog.txt under BMU4bq2048_bin_w folder.
conBattery log file shown as below picture,
(Battery Long Time Monitor has been activated.)
Application Configuration
- A. Auto startup while booting: Operating battery monitor utility automatically when the device booting.
- B. Hide while application startuping: The utility will be minimized when it startuped.
- C. Start battery long time monitor automatically : The utility will operate long time monitoring automatically when it starupped.
