Abstract
A method for managing the charge of a metal-air battery comprising at least one cell. The cell comprises a negative electrode, a first positive air electrode and a second positive oxygen-release electrode. For each cell, during the application of a charge current circulating in the cell between the negative electrode and the second positive oxygen-release electrode, the absolute value of a potential of the negative electrode is compared with 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 threshold value, a surplus charging current, depending on the difference between the current applied to the cell and the charging current, is diverted.
