3.5.4.8 Commands For Battery Charger
3.5.4.8.1 Battery Charge - +CBC
+CBC - Battery Charge SELINT 0 / 1
AT+CBC Execution command returns the current Battery Charge status in the format:
+CBC: <bcs>,<bcl>
where:
<bcs> - battery charge status
0 - ME is powered by the battery
1 - ME has a battery connected, and charger pin is being powered
2 - ME does not have a battery connected
3 - Recognized power fault, calls inhibited
<bcl> - battery charge level
0 - battery is exhausted, or ME does not have a battery connected
25 - battery charge remained is estimated to be 25%
50 - battery charge remained is estimated to be 50%
75 - battery charge remained is estimated to be 75%
100 - battery is fully charged.
Note: <bcs>=1 indicates that the battery charger supply is inserted and the
battery is being recharged if necessary with it. Supply for ME operations is
taken anyway from VBATT pins.
Note: without battery/power connected on VBATT pins or during a power
fault the unit is not working, therefore values <bcs>=2 and <bcs>=3 will
never appear.
AT+CBC? Read command has the same effect as Execution command.
AT+CBC=? Test command returns parameter values supported as a compound value.
For compatibility with previous versions, Test command returns
+CBC: (0-2),(0-100)
An enhanced version of Test command has been defined: AT+CBC=??,
that provides the complete range of values for <bcs> and <bcl>.
