Energy Storage Temperature Monitoring
Systems
In an energy storage string or module consisting of a number of cells , a significant variation in temperature distribution can exist . However , monitoring the whole module ’ s temperature is often hindered by hardware and cost limitations , and typically only a limited number of temperature sensors are employed . |
Competitive Advantage • An innovative model-based temperature monitoring and diagnostic system has been developed for a forced-cooled electrochemical energy storage string using a limited number of sensors
• A unique , multiple-model estimator is used to monitor the temperature of all cells , as well as detect and localise an abnormally overheating cell , with the limited number of temperature sensors – the optimal location of temperature sensors is determined by analysis of the Observability Gramian
Impact • Cost reduction due to a reduced number of temperature sensors
• Increased safety due to the detection of abnormal overheating of cells within a string
