Fuzzy Control (FC) \n 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). \n 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
