Activation and operation mode system for an electro chemical battery for the propulsion of marine, in particular submarine means

An activation and operation mode system for an electrochemical battery for the propulsion of a marine craft, in particular a submarine craft;

• the battery is of the type comprising a plurality of electrochemical cells housed in a chamber (6) containing an anhydrous electrolyte;
• and the activation and operation mode system (1) comprises an inlet valve (8) to enable water inflow from the outside;
• a flow rate regulator (11) to regulate water flow rate through the inlet valve (8);
• an outlet valve (9) to enable outflow of fluids produced by the chemical reaction;
• and a mode or switching valve (16) having an inlet (16A), which is fluidically connected to an outlet conduit (L5) from the chamber (6) for a liquid electrolyte outflow, a first outlet (16B1), which is fluidically connected to an inlet (9A) of the outlet valve (9), and a second outlet (16B2), which is fluidically connected to the chamber (6);
• the activation and operation mode system (1) is characterised in that the inlet valve (8), the outlet valve (9), the flow rate regulator (11) and the mode valve (16) are incorporated in a single outer body (17) so as to define a compact monolithic assembly.
