Smart Battery Management System (SBMS)
An environmentally friendly money saver, the SBMS Smart
Battery Management System is the heart of a completely
new charging technology. It monitors battery status and
controls the charging process. The battery status is read
out in remaining hours of battery life on the transmitter and
receiver displays, so you can recharge the battery pack in
time. The SBMS includes a number of intelligent monitoring
functions.
“Inflection Point and Peak Voltage Detect” stops the char-
ging in time, while an integrated temperature sensor in the
battery pack protects it from overheating. The Charge
Balance Management feature makes sure that only as
much energy is fed to the battery pack as had previously
been drawn from it. A self-discharge counter ensures cor-
rect charging after the battery pack has been stored for a
long time. The battery pack uses an integrated database
and charger interface to set its own charging current.
