Abstract
A method of determining a remaining operating time of an electrical energy storage unit in an aircraft, comprising: using a first sensor arrangement for measuring first performance parameters of the electrical energy storage unit; determining first performance indicators based on the first performance parameters; using at least one second sensor arrangement for measuring second performance parameters of the electrical energy storage unit; determining second performance indicators based on the second performance parameters; comparing the first performance indicators with the second performance indicators to determine consolidated performance indicators; and determining predictive remaining operating times of the electrical energy storage unit based on the consolidated performance indicators, wherein the predictive remaining operating times comprise at least a predictive nominal remaining operating time and a predictive emergency remaining operating time.
