16.3 AT^SBC Battery charging / discharging and charge control
Responses returned by the AT^SBC command vary with the operating mode of the ME:
• Normal mode: ME is switched on by Ignition pin and running the SLEEP, IDLE, TALK or DATA mode. Charger
is not connected.
AT^SBC can be used to query the battery capacity and the power consumption of ME and
application (if value of application was specified before as
<current>).
• Normal mode + charging: Allows charging while ME is switched on by Ignition pin and running the SLEEP,
IDLE, TALK or DATA mode.
AT^SBC returns charger status and power consumption of ME / application. Per-
centage of battery capacity is not available.
• Charge-only mode: Allows charging while ME is detached from GSM network. When started, the mode is indi-
cated by the URC ''^SYSSTART CHARGE-ONLY MODE''.
AT^SBC returns charger status and power con-
sumption of ME / application. Percentage of battery capacity is not available. In Charge-only mode a limited
number of AT commands is accessible (see 16.3.1). There are several ways to activate the Charge-only
mode:
- from Power Down mode: Connect charger while ME was powered down with
AT^SMSO
- from Normal mode: Connect charger, then enter AT^SMSO.
• Alarm mode: The battery can be charged while the ME stays in Alarm mode.
Charging begins once the charger connects to the POWER pins of the ZIF connector (except for the Alarm
mode).
