charger is obliged to adjust its output characteristics in
direct response to the messages it receives from the
battery. In Level 2 charging, the smart battery is com-
pletely responsible for initiating communication and for
providing the charging algorithm to the charger. The
Note: Level 1 smart battery chargers are defined in the ver-
sion 0.95a specification. While they can correctly interpret
smart battery end-of-charge messages minimizing over-
charge, they do not provide truly chemistry-independent
charging. They are no longer defined by the Smart Battery
Charger specification and are explicitly not compliant with this
and subsequent Smart Battery Charger specifications.
Level 2 Smart Battery Charger
The Level 2 or “smart-battery-controlled” smart battery
charger interprets the smart battery’s critical warning
smart battery is in the best position to tell the smart bat-
tery charger how it needs to be charged. The charging
algorithm in the battery may request a static charge
condition or may choose to periodically adjust the
smart battery charger ’s output to meet its present
needs. A Level 2 smart battery charger is truly chem-
istry independent, and since it is defined as an SMBus
slave device only, it is relatively inexpensive and easy
to implement.
