However, to raise the voltage of thedischarging circuit to 250, 200 amp. at 100 volts must beproduced at the booster machine. This amounts to 20kw. Therefore the same number of batteries are chargedwith only 170 kw. being taken from the main source ofsupply neglecting the losses in the machines. In this plant, the facilities for charging the batteriesare comprehensive in principle but simple in battery circuit is controlled through bench boardpanels equipped with knife switches, rheostat handles. Storage battery forming Installation at the 1212 o 800 AMR - 250 VOLTS ^> BATTERIES ON CHARGE M AUTOMOTIVE INDUSTRIESTHE AUTOMOBILE June 9, 1921 -o BATTERIES ON DISCHARGE ililiHH Figs. 1 and 2—Diagramconnections of batteryforming plant and ammeters. On one side of the room there are 288 ofthese circuits and on the other side there are 180 operators can easily handle all of these circuits andthereby charge and discharge a great number of batteriesat the same time. One of the interesting features of thischarging equipment is the method of mounting the gridrheostats. On the side shown in the photographs, theserheostats are mounted nine in a row directly behind andon a level with the board. On the other side, however,there was not enough space for this kind of mounting sothat some of the resistance had to be mounted above thetop panel. This type of mounting precludes accessibilitybut as in two years of operation there has been no needof repairs
