Abstract

A voltaic pile has first and second terminals by which it is charged and discharged. The pile comprises a plurality of modules (3), each having respective third and fourth terminals with a plurality of voltaic cells connected in series therebetween. The modules are connected series-wise or in series-parallel configuration by the respective third and fourth terminals, with the end terminals of the series of modules defining the previously mentioned first and second terminals. A power supply Load (1) is provided with DC input terminals and AC output terminals, the DC input terminals connected via lines (2) with the first and second terminals. Thus, even in the absence of Power charging current or drain current, the power supply is able to draw upon the output of the pile to supply power back to individual modules that may require charging, to maintain balance among the modules. Each of the modules has respective charging terminals connected with the power supply AC output terminals, and also has a transformer with a primary winding connected to the charging terminals and a secondary winding coupled via a rectifier with the cells of the modules, whereby the cells are charged.
