MANIFEST is the project Multi-scale Analysis for Facilities for Energy Storage (MANIFEST). 
This dataset contains data collected at the Willenhall Energy Storage, a battery test facility at the University of Sheffield, during the MANIFEST Project.
The root folder contains a folder for each calendar year during the lifespan of the project: 2017, 2018, etc. 
Each of these folders contains a number of sub-folders corresponding to each single test that was performed in the considered year. The name of these sub-folders relates to the period when the test was performed (e.g. March).
