SYSTEM AND METHOD FOR MONITORING A NICKEL CADMIUM BATTERY IN A PASSENGER AIRCRAFT

摘要

A system for monitoring a nickel cadmium battery (11) having twenty nickel cadmium battery cells (14) connected in series in a passenger aircraft (10) comprises a plurality of cell sensors (17) for measuring the cell voltage and the cell temperature of individual battery cells (14) and a data processing device (21) and is set up to measure the battery current. The data processing device (21) is set up to determine a state of health variable indicating the state of health of the battery (11) from the measurement data from the cell sensors (17) and the measured battery current.
