3.5.4.8 Commands For Battery Charger

3.5.4.8.1 Battery Charge - +CBC

+ CBC - Battery Charge

AT+CBC Execution command returns the current Battery Charge status in the format:

+CBC: <bcs>,<bcl>

where:

<bcs> - battery 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=? Test command returns parameter values supported as a compound value.

+CBC: (0-3),(0-100)

Note: although +CBC is an execution command, 3gpp TS 27.007 requires

the Test command to be defined.

Example

AT+CBC

+CBC: 0,75

Note The ME does not make differences between being powered by a battery or

by a power supply on the VBATT pins, so it is not possible to distinguish

between these two cases.
