Energy storage and portable fan equipment

Are portable energy storage units sustainable?

Achieving the global electricity demand and meeting the United Nations sustainable development target on reliable and sustainable energy supply by 2050 are crucial. Portable energy storage (PES) units, powered by solid-state battery cells, can offer a sustainable and cost-effective solution for regions with limited power-grid access.

What are energy storage systems (PES)?

This includes numerous designs, exploring efficient energy storage technologies such as solid-state batteries, that aim to improve energy density, compactness, safety, durability, and enhancement of overall portability. A PES unit typically comprises a storage system and an inverter for energy conversion.

What cooling systems can be used for PES units?

Common cooling systems usable for PES units. Conventional active cooling systems, such as radiators and fans, are commonly used for heat dissipation in high-power electronic packages. However, they are associated with operational issues, including the requirement for relatively large system volume and high power consumption.

Are Piezoelectric fans an alternative cooling method?

To address some of these challenges, the utilisation of piezoelectric fans has been explored as an alternative cooling method [ 46 ]. Advanced active cooling systems, such as active liquids, are another prominent sub-class of active cooling systems. These systems provide superior cooling performance compared to traditional cooling methods.
