6 FAQs about [Principle of new energy battery immersion test]
How does liquid immersion cooling affect battery performance?
The graph sheds light on the dynamic behavior of voltage during discharge under liquid immersion cooling conditions, aiding in the study and optimization of battery performance in a variety of applications. The configuration of the battery and the direction of coolant flow have a significant impact on battery temperature.
Is immersion method a good option for battery thermal management systems?
It can be understood from the literature survey that the immersion method can be a good option for battery thermal management systems. In the literature, there is a limited number of research on immersion cooling of prismatic Li-ion batteries and heat transfer oils and hydrofluoroethers are selected as working fluids.
Can immersion fluid prevent a failed battery?
To investigate the safety characteristics, they overcharged the middle cell of the pack at 1C. Here they noted that the use of the immersion fluid prevented the thermal propagation of the failed cell to adjacent batteries, limiting the impact of a single failed cell.
Is a battery immersion test more stringent than a water immersion test?
Battery degradation/discharge occurred quicker in 3.5% salinity water. Based off the research completed to date, a battery immersion test in water of lower salinity (<0.1% NaCl) and shorter immersion duration (<30 min) would be more stringent than a test with longer immersion duration (2 hours) in sea water (3.5% salinity).
What is the maximum temperature difference in a 100% immersion battery?
Both figures show that the maximum temperature difference of the battery working in 100% immersion is under 5 °C, which is the desired value for battery performance.
What are the safety implications of battery immersion cooling?
Safety implications of battery immersion cooling discussed. Research gaps in battery immersion cooling presented. Battery thermal management systems are critical for high performance electric vehicles, where the ability to remove heat and homogenise temperature distributions in single cells and packs are key considerations.
