Battery
A battery typically has a pair of drivers: the generic battery class driver that Microsoft provides, and a miniclass driver written specifically for that individual type of battery.
The class driver defines the overall functionality of the batteries in the system and interacts with the power manager.
To develop Battery, you need these headers:
For the programming guide, see Battery Devices Design Guide.
IOCTLs
| Title | Description |
|---|---|
| IOCTL_CAD_DISABLE_CHARGING | This IOCTL is for internal use only. |
| IOCTL_CAD_GET_BATTERY_PROVISIONING_STATUS | This IOCTL is for internal use only. |
| IOCTL_CAD_GET_CHARGING_STATUS_COMPLETE | This IOCTL is for internal use only. |
| IOCTL_CAD_POWER_SOURCE_UPDATE_EX | This IOCTL is for internal use only. |
| IOCTL_INTERNAL_CAD_POWER_SOURCE_UPDATE | This IOCTL is for internal use only. |
| IOCTL_INTERNAL_CONFIGURE_CHARGER_PROPERTY | The IOCTL_INTERNAL_CONFIGURE_CHARGER_PROPERTY control code is sent from a configurable charger to a device that handles configurable chargers. It configures charger properties. |
Enumerations
| Title | Description |
|---|---|
| _POWERSOURCEID | This enum is for internal use only. |
Functions
| Title | Description |
|---|---|
| UPSCancelWait | The UPSCancelWait function cancels all waits initiated by calls to UPSWaitForStateChange. |
| UPSGetState | The UPSGetState function returns the operational state of the UPS. |
| UPSInit | The UPSInit function initializes a UPS minidriver, opens communication to the UPS unit, updates the registry, and causes the minidriver to start monitoring the UPS unit. |
| UPSStop | The UPSStop function causes a UPS minidriver to stop monitoring its UPS unit. |
| UPSTurnOff | The UPSTurnOff function turns off the UPS unit's power outlets, after a specified delay time. |
| UPSWaitForStateChange | The UPSWaitForStateChange function waits until a specified UPS state changes, or until a time-out interval elapses. |
Structures
| Title | Description |
|---|---|
| _BATTERYPROVISIONINGSTATUS | This structure is for internal use only. |
| _CAD_POWER_SOURCE_INFO | This structure is for internal use only. |
| _CAD_POWER_SOURCE_INFO_USB | This structure is for internal use only. |
| _CHARGINGSTATUSCOMPLETE | This structure is for internal use only. |
| _CONFIGURABLE_CHARGER_PROPERTY_HEADER | The CONFIGURABLE_CHARGER_PROPERTY_HEADER structure is a header that is used to create your own structure as an input to IOCTL_INTERNAL_CONFIGURE_CHARGER_PROPERTY. |
| _POWERSOURCESTATUS | This struct is for internal use only. |
| _POWERSOURCEUPDATE | This structure is for internal use only. |
| _POWERSOURCEUPDATEEX | This structure is for internal use only. |
