Is battery energy storage a balancing strategy?
An Improved SoC Balancing Strategy for Battery Energy Storage System in All-Electric Propulsion Ships Current Sharing Effect. J. Electr.
Why are batteries connected in parallel?
Cells are often connected in parallel to achieve the required energy capacity of large-scale battery systems. However, the current on each branch could exhibit oscillation, thus causing concerns about current runaway or even system divergence.
Are parallel battery systems stable?
Nevertheless, we also warn about some risks behind stability. First, parallel battery systems inflict intrinsic capacity loss due to cell inconsistencies, causing capacity loss even reaching up to 34% according to the terminals of the closed orbit.
Why do parallel battery systems lose energy?
For a single cell, it is well accepted that slow kinetics of mass transport and electrochemical reaction result in the loss of the available energy extracted from the cell before reaching the cutoff voltage. Parallel battery systems are found to inflict another intrinsic energy loss due to the inconsistency between cells on different branches.
