Battery Devices Reference

Overview of the Battery Devices Reference technology.

To develop Battery Devices Reference, you need these headers:

For programming guidance for this technology, see:

Functions

 
BatteryClassInitializeDevice

The BatteryClassInitializeDevice routine initializes a new battery device for the class driver.
BatteryClassIoctl

BatteryClassIoctl handles system-defined battery IOCTLs.
BatteryClassQueryWmiDataBlock

The BatteryClassQueryWmiDataBlock routine is used by battery miniclass drivers inside their DpWmiQueryDataBlock routines to allow the battery class driver to process the WMI data block query requests it handles on behalf of the driver.
BatteryClassStatusNotify

BatteryClassStatusNotify notifies the battery class driver of changes in battery status.
BatteryClassSystemControl

The BatteryClassSystemControl routine processes WMI IRPs on behalf of a battery miniclass driver.
BatteryClassUnload

BatteryClassUnload frees resources for a battery device that is no longer in use.
BCLASS_DISABLE_STATUS_NOTIFY_CALLBACK

BatteryMiniDisableStatusNotify disables status notification for a battery device.
BCLASS_QUERY_INFORMATION_CALLBACK

BatteryMiniQueryInformation returns information about the given battery device.
BCLASS_QUERY_STATUS_CALLBACK

BatteryMiniQueryStatus returns status information about the given battery device.
BCLASS_QUERY_TAG_CALLBACK

BatteryMiniQueryTag returns the current battery tag.
BCLASS_SET_INFORMATION_CALLBACK

BatteryMiniSetInformation requests that a battery enter the charging or discharging state, or sets a critical bias value for the battery.
BCLASS_SET_STATUS_NOTIFY_CALLBACK

BatteryMiniSetStatusNotify sets the battery capacity and power state levels at which the class driver requires notification.

Structures

 
BATTERY_MINIPORT_INFO

Battery miniclass drivers fill in this structure before calling the battery class driver's BatteryClassInitializeDevice routine.
BATTERY_MINIPORT_INFO_V1_1

Battery miniclass drivers fill in the BATTERY_MINIPORT_INFO_V1_1 structure before calling the battery class driver's BatteryClassInitializeDevice routine. BATTERY_MINIPORT_INFO_V1_1 is an updated version of the previous structure BATTERY_MINIPORT_INFO.
BATTERY_NOTIFY

A battery miniclass driver receives a BATTERY_NOTIFY structure when its BatteryMiniSetStatusNotify routine is called.
BATTERY_TAG_CHANGE

This structure is reserved for system use.
BATTERY_WMI_CYCLE_COUNT

Defines information about number of charge cycles of a battery for use with the BatteryClassQueryWmiDataBlock function.
BATTERY_WMI_FULL_CHARGED_CAPACITY

Defines information about the capacity of a battery for use with the BatteryClassQueryWmiDataBlock).
BATTERY_WMI_RUNTIME

Defines information about the estimated runtime of a battery for use with the BatteryClassQueryWmiDataBlock function.
BATTERY_WMI_STATIC_DATA

Defines static data about a battery.
BATTERY_WMI_STATUS

Defines battery status information.
BATTERY_WMI_STATUS_CHANGE

This structure is reserved for system use.
BATTERY_WMI_TEMPERATURE

Defines information about temperature of the battery for use with the BatteryClassQueryWmiDataBlock function.
