Abstract
Method of operating a secondary Metal-Air electrochemical cell with a metal anode and an air cathode including the steps of (a) at start of a charging session, creating in less than 2 seconds an oxygen gas-shield on the electrolyte side of the air-electrode obstructing ion passage between the bulk of the electrolyte and the air-electrode; (b) charging the cell without anodic polarization of the air-electrode with the help of (i) electric conductive material placed between the electrolyte side of air-electrode and the bulk of electrolyte, and, (ii) the oxygen gas-shield obstructing passage of ions of the electrolyte between the electrolyte side of air-electrode and the bulk of electrolyte; (c) removing the oxygen gas-shield at start of a discharging session.

Abstract
A Discrete Power Distribution Unit (DPDU) for establishing with an external system a bi-directional transfer of energy to or from serially connected subset of the units of a battery pack wherein said DPDU includes at least a plurality of Switchable Battery Units (SBU) connected in series, forming a Switchable Battery Units String (SBUS) providing a current path with a pair of voltage output terminals; each SBU comprising at least an Electrical Energy Storage Unit (EESU), and, individually controlled Unit Switching Means (USM) allowing a state "Inserted" in which the EESU is inserted in the current path of the SBUS and another state "Not- Inserted" in which the current path of the SBUS doesn't include the EESU; and a Central Processing Unit permanently selecting the most suitable subset of EESUs to be Inserted and actuating accordingly said individually controlled USMs.
