Xing Mobility total immersion refrigerated batteries: 3,000 cycles and ultra-fast charging – Technology – Hybrids and electrics

The performance of the drums Depends on staying in a optimum temperature range, preventing it from getting too hot when powering the traction or recharging system, and from being too cold, which adversely affects its performance. old cooling systems area or the most modern liquidare far from achieving their goal in all conditions. Xing Mobility believes that the best solution for maintaining batteries at their optimal temperature is immerse them in the coolant. The immersion cooling technology is not new, but this Taiwanese company believes that it is ready for use in electric vehicles.

Modern batteries need a heat management strict to keep your temperature in an optimal range. If it is too low, the vehicle does not reach its maximum performance. If it is too high, several problems can occur, such as further degradation of the battery, reducing its lifespan, or the risk of thermal runaway, which is essentially a consequence caused by overheating.

Electric vehicles initially used forced air cooling to keep the battery at the optimum temperature. This system was clearly ineffective in the case of, for example, the Nissan Leaf. For this reason, most electric vehicles today use liquid cooling, which has greatly improved the results. However, it is far from perfect. Its operating scheme is based on the use of cooling plates, ducts or channels inside the batteries which individually cooled cells. The result is that heat transfer only takes place in the area where these cooling elements are located.

The immersion of the battery allows a better distribution of the temperature between each of the cells and contributes to increase the rate of charge and discharge without danger of overheating.

For it, flood the battery with coolant it’s a much more efficient solution, although it also presents its own problems. The first and most important is that the fluid used must be a dielectric coolant (a low conductivity electrical insulator) durable and safe.

The Taiwanese company Xing Mobility presented for the first time in Stuttgart, Germany, as part of the Battery Show Europe, a new battery, Immersion X25who uses an immersion cooling system based on a fluid having these characteristics. Its cooling system allows a better distribution of the temperature between each of the cells individually. This, in turn, helps to increase loading and unloading rate no risk of overheating. These characteristics are particularly important for applications in heavy electric vehicles which are used in different services or for high performance electric carswhere battery packs are typically bulky and subject to high thermal stress situations.

The Xing Mobility Immersio X25 system combines a battery, a management system and an active safety module to enable “super fast charging”, although it doesn’t specify how much power it could handle. The result is that the useful life of the battery cells can be doubled. reaching up to 3,000 charge and discharge cycles. The system is primarily designed for utility vehicles with large batteries.

This technology is not really new in the automotive sector. Malhe already presented a system of this type last year, even if Xing Mobility is the first to market it. For the moment, he claims to have signed a contract with an Asian manufacturer, whose name he did not mention, to implement this system in a utility vehicle whose production is scheduled for the end of the year.
