initiates polling and therefore charging, it is suggested that the Level 3 Smart Battery Charger disable the
automatic broadcasts of the battery by setting Battery Mode CHARGER_MODE bit. See the Smart
Battery Data Specification for details (refer to the References section).
6.3.3. Charge Termination
Like the Level 2 charger, Level 3 Smart Battery Chargers will discontinue charging when an
AlarmWarning() is written with critical error bits set, if either ChargingCurrent() or ChargingVoltage() are
set to zero, or when the Safety Signal indicates that no charging is allowed. Additional methods of charge
termination are allowed. Charging may resume when charge initiation conditions in 6.3.2 are met.
6.3.4. Charge Current and Voltage
The maximum charging current and voltage of the Level 3 Smart Battery Charger is determined by the
manufacturer and is programmable through the ChargingCurrent() and ChargingVoltage() commands.
Default values for these may be zero or any non-zero range determined to be safe for any chemistry. Non-
zero default values, when used, must only be enabled when the Safety Signal indicates that “controlled”
charging is allowed. The default charge current and voltage must not be persistent; any new value of
ChargingCurrrent() or ChargingVoltage() must over-write any default values.
