Abstract
The system () is provided for managing at least one sub-assembly () of an electric battery. Each sub-assembly comprises a plurality of power storage cells (). The system includes, for each power storage cell, a circuit () for managing the state of the cell and a communication circuit (), which is configured such that it receives and transmits data relative to the cell. The communication circuit is configured such that it transposes, over a carrier frequency, the data to be received and transmitted, the value of said carrier frequency being greater than or equal to 1 GHz. The management system further includes, for each sub-assembly, a loss cable () connecting the power storage cells of said sub-assembly. The loss cable acts as a waveguide and is coupled by capacitive coupling to the communication circuit of each power storage cell.
