17.3AT^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 only charger status and power consumption of ME / application. Percentage 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 only charger status and power consumption of ME / application. Percentage of battery capacity is not available. In Charge-only mode a lim- ited number of AT commands is accessible (see 17.3.1). 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, but AT^SBC returns only charger status and power consumption of ME / application. Percentage of battery capacity is not available.

For details about charging please refer to [2].
