Chargers

Fuzzy Control (FC)

With this automatic control engineering principle, the variable charge current for the battery is accuarately calculated on the basis of checking values via voltage and temperature, including the temporal derivation of these two variables, and is then adapted to the exact condition of the battery (charging state, age).

This means the battery charging is particularly gentle and lifetime increased considerably (up to 3000 charge/discharge cycles). Battery chargers fitted with Fuzzy Control therefore do not require a special discharge function.

\n Delta voltage charging cut-off (DV)

To recognise when the battery is fully charged, the voltage curve is permanently monitored during the charging process. When the battery starts overloading, a characteristic voltage drop (minus delta voltage) is detected at the gas-tight Bosch NiCd battery cells. This criterion is used as a checking value to initiate the cut-out of the constant charge current, or to reduce to trickle charge. This gently method prevents overloading and contributes to the long lifetime of the battery. Battery chargers fitted with delta voltage charging cut-off therefore do not require a special discharge function.
