Fast! You are hot and sweaty after working in the sun all day. What is the fastest way to cool down?
A. Drink an iced tea.
B. Holding a wet handkerchief to your forehead?
C. Diving your head in a pool?
If you said C, go to the head of the class!
Xing Mobility is a supplier of electric vehicle technologies based in Taiwan. At the Battery Show Europe in Stuttgart, Germany, this week, it introduced a new battery system, cleverly named Immersio XM25, that offers full immersion cooling. The company claims the new system is particularly suitable for heavy-duty electric vehicles used in logistics, construction, agriculture and mining. electric†
The Immersio XM25 combines a battery pack with a battery management system and an active safety module. The company says it is building on the Immersio 1.0 battery system that it debuted in 2019.
With Immersio XM25, or immersion cooling technology, the battery cells are completely surrounded by coolant, just like you would be in a swimming pool. Cooling plates or channels that only touch one or two sides of a battery cell are the norm, but the heat transfer takes place over a significantly smaller area than with immersion cooling. Xing Mobility claims a more even temperature distribution in the battery cell and higher cooling efficiency enables “super-fast” charging and doubles battery cell life.
The system is primarily intended for commercial vehicles with correspondingly large batteries. Charging is possible up to 1°C while discharging can take place at 1.67°C. System voltages of up to 800 volts are possible, and Xing says a life of over 3,000 cycles is likely.
According to Xing Mobility, it has already found a first customer for the new system. The Immersio XM25 is currently being integrated into a model by an unnamed Asian commercial vehicle manufacturer with production expected to begin in late 2022.

Last year, Tier One supplier Mahle also presented a system for: battery immersion cooling but with a focus on electric cars† “Submersible cooling is paving the way for a whole new generation of battery systems,” said Martin Berger, Head of Group Research and Advance Engineering at Mahle. In July 2020, the supplier had presented a new cooling condenser that is also optimized for the fast charging of electric vehicles. The condenser is “powerful enough” to be paired with the new cooling system, the spokesperson said.
Mahle says he plans to use his know-how to develop new, integrated solutions for e-vehicles. The focus is on the areas “where e-mobility still needs a boost”, especially charging speed, range, resource conservation and price. It also recently announced that it has developed new electric motors for electric vehicles that: do not use magnets† The lesson here is that no one has a monopoly on innovation when it comes to electric transportation. No one.
