Programmed battery charging system
First Claim
1. In a programmed battery charging system the combination of a fully regulated, constant current boost charging circuit, a plurality of banks, each bank having a number of series connected batteries therein, a conductor connecting each bank of batteries to the charging circuit, a series of first switches each interposed in a conductor, a stand-by circuit connected across the charging circuit, a visible indicator means and a second switch interposed in series in the stand-by circuit, and a continuously operable sequence control means adapted to progressively actuate and disconnect each first switch to boost charge successive banks of batteries, then actuate the second switch to monitor a non-charging period of the system and finally initiate the boost charging circuit following the non-charging period.
