Abstract
Electrical energy storage is widely used not
only in the mobile applications but also in stationary
applications as like uninterruptable power supply. An
energy storage system with the high energy density and
high-power capability is very important for some
specific applications like electric vehicles (EV). Lithiumion-
batteries are well known for their high energy
density while super-capacitors have high power
capability. Lithium-ion capacitors (LiCs) which are a
hybrid energy storage technology consisting of the
lithium-ion batteries (LIBs) and super capacitors (SCs),
combine the advantages of LIB and SC and eliminate
their negative properties. However, the reliability of all
types of energy storage technologies including LiCs can
be drastically affected by overheating issues. These
issues are more likely to happen in the closed casing
battery pack. In this research, many experiments are
performed to investigate the effect of current magnitude
on the temperature distribution pattern in a module of
12 LiC cells. Then, in the COMSOL Multiphysics
environment, a numerical solution is designed for a brief
study of temperature distribution. The presented model
accounts for different heat sources without getting into
an electrochemical model. The simulation result shows a
good agreement with the experimental results with an
error of less than 5%. The presented model can be used
to design a thermal management system with the focus
on the hottest parts of the module.
