PROCESS AMD CONNECTION LAYOUT FOR RECHARCHING BATTERIES HAVING ADHERENT OR SOAKED ELECTROLYTE

The inventive process and connection layout are designed for charging, especially deep- and fast-charging of batteries having adherent or soaked electrolyte on the basis of the Wronski effect. In the process according to the invention, charging of a preliminary tested battery is accomplished by a superposed alternating current that has a magnitude ranging from at least 2.5C to at most 4C. The resonance frequency of the battery is determined through a digital frequency response analysis by applying a white noise current pulse. The waveform of the superposed ac pulses is generated by a Power Factor Control circuitry that charges the resonant circuit of the battery through a power pulse modulator. The core feature of the connection layout according to the invention is that when charging is in progress, the control unit of the main circuitry sets the value of the resonance frequency fo of the battery to be charged with the accuracy of ±2% at every moment, wherein said resonance frequency is defined by a digital frequency response analysing circuitry.
