The kernel-mode battery class driver, battc.sys, provides device-independent battery support and exports support routines for use by all device-specific battery miniclass drivers.
The battery class driver takes care of the following tasks for miniclass drivers:
- Performing a large part of miniclass driver initialization, including allocating system resources and space for the miniclass driver's class data
- Handling device control IRPs (IRP_MJ_DEVICE_CONTROL) that specify battery class IOCTLs. (See the Microsoft Windows SDK for information about these IOCTLs.)
- Serializing requests to the battery device Bear share.
- Administering DC power policy for the operating system
- Freeing system resources if the miniclass driver is unloaded
- Handling certain standard battery WMI classes
