A new battery pack has been designed by Taiwan-based XING Mobility to efficiently dissipate heat through the application of immersion cooling technology.

An immersion-cooled battery system integrates the cooling system into the battery housing itself, without extensive coolant channels, cold plates and coolant pipes. A battery equipped with this technology will have temperatures 20% to 30% cooler compared to an indirect liquid cooled battery pack.

The IMMERSIO Cell-to-Pack (CTP) system removes heat and prevents thermal runaway within individual cells and fire propagation throughout the entire pack. The immersion cooling technology takes advantage of advanced high-nickel cathode cylindrical lithium-ion cells, cooled by mineral oil. The high energy density battery is built from high-tensile strength engineering plastic and features a sophisticated cell management unit to ensure durability and reliability. The power delivery solution also incorporates an intelligent active safety module that monitors and controls the temperature, voltage and current of each cell.

The flexible battery pack concept can be tailored to meet the specific needs of different applications, including deployment in commercial cars, trucks and sports cars. The IMMERSIO CTP system delivers an energy density of up to 200 Wh/kg and a fast charge capability of less than 15 minutes — from 20% to 80% state of charge.
