Why Do We Need Battery Monitoring If We Do Discharge Testing?
Introduction This is a question that is often asked, and the answer is relatively simple. A discharge test measures the capacity of the battery and a battery monitoring system is a maintenance tool. Let me explain further. The Importance of Capacity Testing A lead acid battery is a collection of lead-based electrochemical cells, each with a nominal voltage of 2 Volts, assembled in series to ...

Exergy analysis of a multi–tank thermal storage system for solar heating applications
This paper presents the results of an experimental study on the stored exergy of a stratified multi–tank system when subjected to various charge and discharge strategies. Tests were performed over 8–h and 48–h test periods, for constant temperature charging, variable input power charging, constant volume hourly draws and variable volume hourly draws. For each set of test parameters, three ...
