Facts: Smart Battery

The widely used Smart Battery standard, which has been released by the SBS Forum, defines several classes of devices typically available in a battery powered system:

data (battery)
charger
selector
manager

Each of these devices is standardized as a SMBus slave.

There are IRD files available for Tracii XL / Tracii XL 2.0, which make debugging of a Smart Battery setup a lot of easier.

The traced data bytes transferred by Smart Battery devices are converted into human readable clear text by using this feature.

For example in picture 1 you can see that an SMBus master has transferred an 0x16 to an SBS battery. Without the SBS standard on the developer's desktop this value is very difficult to interpret.

In picture 2 you can see the high-level interpretation of the transferred data byte. Another example can be found in the pictures 3 and 4.
