PULSE GENERATION DEVICE FOR CHARGING A VALVE-REGULATED LEAD-ACID BATTERY

摘要

There is disclosed a pulse generation device (1) for improving the life of a valve-regulated lead-acid battery (2), comprising a pulse generator capable of generating direct current charging pulses at a plurality of different frequencies corresponding to different ones of a plurality of potential sulfation patterns on the plates of lead-acid batteries, and configuration means (6) for configuring said pulse generator to generate pulses at a selected one of said plurality of frequencies, whereby said frequency can be selected on the basis of the expected sulfation pattern of the plates of the battery to which said pulse generation device is to be connected.
