STORAGE BATTERY ARRANGEMENT WITH IMPROVED CONDITION MONITORING

摘要

The invention discloses a storage battery arrangement, comprising - a plurality of storage battery cells connected in series; - a central network node designed to transmit data by means of the storage battery cells and connected to the series connection of storage battery cells; - a plurality of cell network nodes designed to transmit data by means of the storage battery cells, each cell network node being connected in parallel to a storage battery cell; - a control device designed to command at least one first cell network node to apply a test signal having at least one predetermined frequency to a first storage battery cell to which said first cell network node is connected, and to command a second cell network node connected to a second storage battery cell to determine, on the basis of the signal response of the second storage battery cell to the test signal, at least one condition of the second storage battery cell.
