Batteries are widely used as storage devices and they have recently gained popularity due to their increasing smaller sizes, lighter weights and greater energy densities. These characteristics also render them suitable for powering electric vehicles. However, a key gap exists in that batteries are solely used as storage devices with a lack of information flow. Next-generation battery technologi...

The article describes the results of research aimed at identifying parameters equivalent circuit a lithium-ion battery cell, based on HPPC (hybrid pulse power characterization) tests. OCV (open voltage) characteristic was determined, which approximated using functions various types, while making their comparison. internal impedance cell also identified in form Thevenin RC with one or two time c...

Li-ion batteries are the most widely deployed battery energy storage system (BESS) today but understanding benefits and cost-effectiveness for a wide range of grid services needs to be fully validated further expand market. Hence, various chemistries currently must evaluated compared in terms performance, lifecycle, economics, safety under using standardized testing protocols. In this work, com...
