Difficult battery charger task

boothmultipler · 2005-06-27T13:03:17+00:00

Dear All, I have been given a task to design a battery charger for SAFTbatteries in series. There are 170 batteries in series. The charge current is 12Amps.(6A above a level) The discharge current is 120 Amps.I have never dealt with high currents before. The charge voltage is 170*2.1 = 357 volts. I consider to use LM350's in parallel to limit thecharge current but will they withstand such a high voltage?Any suggestions for the circuit? And how am I going to limit the discharge current to 120A?Any Ideas? Thanks

I'd do the goggles one better and get a face shield as a complement. I'd wear long sleeves and full trousers, and only wear clothes I wouldn't mind throwing away when little holes start appearing everywhere. Before I started, I'd read and memorize this page:
