Claim:
1. A method for managing charge of a metal-air battery comprising at least one cell, the at least one cell comprising at least a negative electrode, a first positive air electrode, and a second positive oxygen-release electrode, the method comprising, for each cell, during application of a current to the at least one cell that results, during charging, in the flow of charging current between the negative electrode and the second positive oxygen-release electrode: comparing an absolute value of a potential of the negative electrode to a critical threshold value, the potential of the negative electrode being determined relative to the first positive air electrode; when the absolute value of the potential of the negative electrode reaches the critical threshold value, diverting an excess charging current that is a function of a difference between a current applied to the at least one cell and the charging current.
