Battery Charge Control by State of Health Estimation
Indonesian Journal of Electrical Engineering and Computer Science, 2017 Battery lifetime is one of importance consideration in smart system with energy storage system, because it is shorter than others. Extended of battery lifetime can give benefit to entire system, especially to reduce cost. The lifetime is commonly estimated by State of Health (SOH). Decreasing of SOH indicates degradation of battery.

State of Charge Estimation of Thermal Storages for Distributed Generation Systems
Energy Procedia, 2014 AbstractThe aim of this work is the development of three different models to calculate the enthalpy content of a stratified water thermal storage tank from discrete temperature measurements. The difficulty related to enthalpy value evaluation comes from the discrete temperature measurement along the storage (often only 2 to 4 temperatures along the ...
