VERFAHREN UND SCHALTUNGSANORDNUNG ZUR BESTIMMUNG DER LADEZEIT EINES AKKUMULATORS

摘要

A circuit arrangement comprises an electronic mains connection part (SN) which can be connected to voltage sources of different magnitude for charging an accumulator (B), a logic signal unit (LG), a microcontroller (MC) and a charging condition display (A). The microcontroller generates cyclic pulses, combines the signals supplied by the logic signal unit, and controls the charging condition display. To determine the charging time of the accumulator and/or to control the charging condition display, the following parameters are obtained from the secondary circuit of the electronic mains connection circuit by means of the logic signal unit : Application or non-application of an input voltage (EK), various input voltage levels (12 volt, 48 volt, 100-240 volt), load connected or not connected (MK) and residual capacity threshold exceeded or not exceeded (LC).
