Aims
To develop a web based knowledge bank that is accessible to the general public. The knowledge bank will contain independent data, rest results, reports and case studies related to energy storage systems. The goal is to help provide a reliable source of information to the stake holders in the renewable energy storage industry.
Background
There has been a lot of study done in the area of battery modeling and management systems to help better our understand of and hopefully predict battery performance. But there are a number of different factors that affect the performance of a battery during operation.
For the purpose of this project, in the following figure [1] shows a simple model for a battery. This is the most simplistic battery model showing Resistance Ro, open circuit voltage Uoc and the terminal voltage UL. Ro in this case we are assuming to be purely resistive, can be used to assess the health of the battery. The internal resistance(Ro) of batteries will increase over time as the health of the battery deteriorates. In the case of Valve-Regulated Lead-Acid batteries(VRLA) when the internal resistance is increased to %150 of the original value, the capacity of the battery will be reduced to %80[2]. Often it is hard to determine the exact parameters of batteries even when data are collected under strictly controlled environments. (temperature, humidity). In this project, we will research and organize useful information and data to produce a knowledge bank.
