XING Mobility, a Taiwanese supplier of EV technologies, has introduced a new battery system with immersion cooling at the Battery Show Europe in Stuttgart. According to XING Mobility, the IMMERSIO™ XM25 is particularly well suited for heavy duty vehicles.

The IMMERSIO™ XM25 combines a battery pack with a battery management system and an active safety module, according to the company. The new product builds on XING Mobility's IMMERSIO™ 1.0 battery system, which debuted in 2019.

IMMERSIO™, or immersion cooling technology, involves the battery cells being completely surrounded by coolant. Cooling plates or channels that only touch one or two sides of a battery cell are otherwise common – the heat transfer takes place over a significantly smaller area than with immersion cooling. As an advantage of its own solution, XING Mobility claims a more even distribution of the temperature in the battery cell and the efficiency of the cooling. This is supposed to enable“super-fast”charging and double the service life of the cells.

The C-rate shows that the system is primarily designed for commercial vehicles with correspondingly large batteries: charging is possible with 1C, discharging with 1.67C. System voltages of up to 800 volts are possible, and XING Mobility states a service life of over 3,000 cycles.

According to XING Mobility, it has already found an initial customer for the new system: The IMMERSIO™ XM25 is currently being integrated by an unnamed Asian commercial vehicle manufacturer in a model whose production is scheduled to start at the end of 2022.
