abstract = {Self-reconfigurable batteries represent a new and promising
technique of electrochemical storage. The application of
self-reconfigurable batteries can resolve the challenge of
efficient renewable storage in solar-powered installations.
In this paper, the problem of solar panel’s Maximum Power
Point (MPP) tracking utilizing self-reconfigurable batteries
is explored through modeling. The efficiency of energy
storage is improved by removing the intervening DC/DC
converter, which is usually necessary for solar PV
applications. To make such a system functional, a Switching
Battery Management System (SBMS) is proposed instead of a
traditional couple of DC/DC converter and usual BMS. This
system allows the series connection of multiple battery
modules of different sizes, States-of-Charge (SoC), and
States-of-Health (SoH). Two main challenges arise by the
proposed implementation: tracking MPP of solar panels
through battery cell switching and maintaining an equal
(balanced) SoC of the separate cells/modules. The
theoretical investigation includes developing the distinct
software parts: digital twins of the battery module and
solar PV modules that interact with the SBMS and the
algorithm according to which the proposed SBMS will operate.
The SBMS algorithm, based on sorting the battery cells
according to their SoC, resolves both challenges. Having
this promising theoretical starting point, a working
prototype was developed. The prototype worked as expected
and was tested under field conditions, being integrated into
the power grid as part of a virtual power plant.},
