Immersed in thermal management

Effective thermal management is essential for the safety and performance of battery energy storage systems (BESS). Thermal runaway events can have catastrophic consequences and poor heat dissipation hurts BESS performance in the long run. While air- and liquid-cooling are the industry standard for tackling high temperatures, immersion has emerged as a novel approach.

EticaAG is taking a different approach to thermal management. The company offers immersion-cooled storage products for grid-scale and commercial and industrial (C&I) applications, such as the 3.06 MWh Legion C20 and the 340 kWh Power Cabinet. Unlike conventional liquid-cooled BESS, which operate by circulating coolant to cold plates to manage battery cell temperature, EticaAG’s immersion …
