Abstract
<div class="section abstract"><div class="htmlview paragraph">Because of their multiple advantages, lithium-ion batteries are widely employed
in a variety of applications ranging from wireless headphones to electric cars.
They do, however, have disadvantages such as thermal issues, cell voltage
imbalance, and safety concerns. The cell voltage in a battery pack must be
balanced in order to determine its overall capacity and lifespan. A battery pack
of four 3.7 V/1200 mAh lithium-ion batteries is researched under fixed
temperature settings in this paper, with the goal of balancing cell voltages
during charging and discharging via passive cell balancing. A battery management
system (BMS) is used to monitor changes in cell temperatures, voltage, and
current to ensure the lithium-ion battery’s health. The simulation environment
was created with MATLAB, and simulation results for various temperatures are
provided. The proposed method was tested utilizing a cloud-based battery
parameter monitoring system, and the cell-balancing analysis is reported as a
result. Overall, this work presents a practical approach for managing and
balancing lithium-ion battery cell voltages in order to ensure safe and
consistent battery performance.</div></div>
