The invention of the CCS-process was made to revolutionize the charging of rechargeable batteries. The CCS charge controller utilizes exceptional features for regulating the power supply during battery charging that ensures full under/overcharge protection. It is based not on simple external measured data but, for the first time, the CCS-technique recalculates the inner impedance between electrodes and electrolyte related to the processes within the cell. By this the new charger is suitable for all types or sorts or sizes of batteries, singly or series mounted.. Regardless of the state of charge, leakage tendency or ambient conditions the battery is charged 100% full with maximum reliability within several minutes (NC).
Although a discharge cycle before charging is not needed no Memory-Effect will occur.

Besides this, the new process has valuable advantages for the design of battery powered products:
    The same circuit is suitable for different batteries (NC,NMH,..)
    The battery is connected with a simple two lead wire without additional sensors (NTC).
    The electronic circuitry does not need any adjustments or calibration during production.
    The precise process improves the reliability and life of the battery (>5000 Cycles)
    Foolproof operation over a wide extended temperature range
    Proper function of the product and no worries anymore with LOW-BAT
    Customer satisfaction and savings in design, production, reclamation, service

With the above mentioned features and being the only method to charge a battery fast and reliable while improving it's life at the same time, the CCS-process can change our mind of uncertain rechargeable batteries in the past to get a stable and reliable power source for portables in the future.
The paper describes functions and features of the new CCS-process in relation to conventional methods and will give  hints for the design and development for different portable applications.
