Xing Mobility has launched an immersion cooled cell to pack (CTP) battery system for electric vehicles.

The Xing 900V IMMERSIO CTP, shown for the first time at the IAA Mobility motor show in Munich this week, can be customized to meet the specific needs of various applications, such as sedans, commercial cars, trucks, sports cars and SUVs.

Cell to pack designs directly integrate individual battery cells into the pack without using module-level electronics and so have more sophisticated cooling requirements to support fast charging and reliable operation.

The patented Xing technology uses high nickel cathode cylindrical lithium-ion cells, cooled by mineral oil to enable an energy density of up to 200 Wh/kg with a fast charge capability of less than 15 minutes from 20-80% State of Charge (SoC).

The key to the IMMERSIO CTP is the patented immersion cooling technology developed by Xing in Taiwan. This efficiently remove heat and prevent thermal runaway within individual cells and fire propagation throughout the entire pack. The CTP system is built from high tensile strength engineering plastic and features a sophisticated Cell Management Unit (CMU) to ensure durability and reliability. The unit incorporates an Intelligent Active Safety Module that monitors and controls the temperature, voltage, and current of each cell.

The highly flexible pack concept can be tailored to meet the demands of each customer’s specific application. This process starts from a discussion of customer requirements; continues through prototyping, testing and certification; to manufacture a battery solution suited perfectly to the customer’s needs. Afterwards, IMMERSIO continues to monitor the real-world performance of the product in the field and may offer further improvements based on this information.
