This patent describes a battery charging system with which in combination with an AC voltage source, a charging circuit of storage batteries is interconnected in series at intermediate junctions between end terminals of opposite polarity. The charging circuit has voltage converters respectively connected to the batteries and switching control operatively connected to the voltage converters for controlling the charging of the batteries. The improvement consists of a jumper connected to the intermediate junctions for interconnecting the voltage converters in series with each other and in parallel to the respective batteries. The voltage converters include current rectifiers and a transformer having secondary windings respectively coupled exclusively to the current rectifiers and primary windings connected to the switching control, at least one AC load, and a power distributor operatively connects the source to the load and the charging circuit. A voltage inverter operatively connects the power distributor to the batteries, and firing control is connected to the batteries and the inverter for establishing a predetermined wave shape with respect to voltage applied from the batteries to the power distributor.
