Writing Battery Miniclass Drivers
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.
The miniclass driver handles device-specific functions such as adding and removing a battery, and keeping track of its capacity and charge. The miniclass driver exports routines that the class driver calls to get information about the devices it controls.
