Investigation of a Passive Thermal Management System for Lithium-Ion Capacitors

Journal Contribution - Journal Article

Lithium-ion capacitors (LiCs) have emerged as a
promising technology for automotive applications due to the solution
offered by their power density, high voltage operation and their
excellent durability (more than 2 million cycles). Nevertheless, the
reliability of LiCs can be drastically affected by overheating issues
which raise the importance of thermal management. Nowadays,
active cooling is employed to keep the battery systems temperature
in range. However, due to the bulkiness and weight of the existing
active cooling systems, latent heat thermal energy storage through
the use of phase change materials (PCMs), represents an attractive
way. In this paper, paraffin is investigated experimentally and
simulated as a PCM cooling solution for the thermal management
of a dual-LiC module. Moreover, since paraffin presents a low
thermal conductivity characteristic, an additional component such
as aluminium mesh grid is inserted to the system to solve the low
conductivity issue. Results show good performance of the Al-PCM
on the battery thermal management for both ESSs with a relatively
lower temperature. The Al-PCM combination was able is lower the
temperature to 36 °C compared to natural convection (46 °C).
