125 enabling the pressure in the battery to remain constant after drainage is complete recharged material is pumped into storage tanks 111 and 113 by pumps 105 and 107 through material exchanging pipes 119 and again vent pipes 117 act as vents to tanks 101 and 103 via pipes 125 for generally maintaining constant pressure inside the battery and enabling possible gaseous reactants to be effectively transfered in the present embodiment an interface 121 at the side of the vehicle approximately where a gas cap would be connects the four pipes positive and negative vent pipes 117 and positive and negative material exchanging pipes 119 to a charging station using secure methods in alternate embodiments the means by which the connection is secured may vary and interfaces for connecting to recharging stations may be placed in various different locations on the vehicles such as but not limited to on the hood behind a license plate underneath the vehicle etc in the present embodiment interface 121 connects to a standard adaptor 123 at the charging station there may be more than one material type being commonly used in batteries at any given time adapter 123 shows four pipes passing through it however alternate embodiments may comprise as many pipes as necessary to move all or most of the different types of material currently in market circulation furthermore in some embodiments adaptors may be made to be interchangeable to enable them to.
