Taiwan's Xing Mobility uses new cooling tech to keep batteries from catching fire

TAIPEI: Taiwanese company Xing Mobility, a leading provider of advanced EV battery systems, is showcasing its immersion cooling technology at CES 2024 in Las Vegas.

Founded in 2015 by veterans of Tesla and Panasonic, Xing Mobility has been working on improving battery thermal management.

Instead of relying on traditional air or liquid cooling systems, Xing immerses battery cells in a special dielectric fluid. This fluid, engineered for optimal heat transfer, surrounds and envelops each cell, ensuring uniform and rapid cooling.

The company's latest Cell-to-Chassis (CTC) design allows customisation based on the specific requirements of passenger and commercial vehicles.

Xing Mobility will introduce three global firsts at the Jan 9-12 CES 2024.

> Immersio Cell-to-Pack (CTP) architecture: This innovative design boasts a gravitational energy density of up to 200 Wh/kg and a volumetric energy density of up to 400 Wh/L, the highest in the world. This breakthrough allows for significantly larger battery capacities in passenger vehicles without sacrificing space, effectively addressing range anxiety.

> Immersio XM25 Battery System: The first mass-produced immersion cooling battery pack, the XM25 offers 25 kWh of power and is readily available for both vehicle and Energy Storage System (ESS) applications. Extensive testing ensures its reliability, environmental resilience, and efficient power output.

> Three-nail safety test: Xing Mobility will showcase the results of a three-nail penetration safety test conducted on an Immersio battery pack at 100% State of Charge. According to the company, the test would show the battery's safety and stability. The immersion cooling technology would be able to suppress thermal runaway and thus fire outbreak.

Xing Mobility's CES debut coincides with its entry into the US market.

The company said it is scouting for US dealers to accelerate the adoption of its new technology across passenger vehicles, commercial vehicles, industrial machinery, and ESS applications.

"Xing Mobility is providing a safer and more stable choice for battery thermal management to the global market, rewriting the safety norm for industrial electrification," said Xing Mobility co-founder & CEO Royce YC Hong.
