What is heat storage in a TES module?
Heat storage in separate TES modules usually requires active components (fans or pumps) and control systems to transport stored energy to the occupant space. Heat storage tanks, various types of heat exchanges, solar collectors, air ducts, and indoor heating bodies can be considered elements of an active system.
What is sensible heat storage (SHS)?
TES systems primarily store sensible and latent heat. Sensible heat storage (SHS) involves heating a solid or liquid to store thermal energy, considering specific heat and temperature variations during phase change processes.
What are the different types of thermal energy storage systems?
Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
Why is battery thermal management important?
Battery thermal management is crucial for the design and operation of energy storage systems [1, 2]. With the growing demand for EVs and renewable energy, efficient thermal management is essential for the performance, safety, and longevity of battery packs [3, 4].
How does a battery thermal management system work?
In terms of battery thermal management systems, PCMs are incorporated into battery packs to absorb and dissipate surplus heat produced during use . When there is a rise in battery temperature, PCM absorbs this generated heat and undergoes a phase transition from solid state to liquid through which the thermal (heat) energy is stored.
