XING Mobility’s electric supercar uses novel battery cooling system

Taipei-based electric powertrain startup XING Mobility has announced a 1,341 hp rally-inspired supercar that’s not afraid to leave the roadway. Miss R has 4 independent 350 V motors and 4-wheel torque vectoring, and XING says she will be able to reach 100 km/h in 1.8 seconds.

In response to the inevitable comparison to the new Tesla Roadster, XING says it designed Miss R with an entirely different aspiration: delivering great performance on-road, on-track and off-road.

The “secret sauce” behind Miss R’s surprising power is a patented immersion cooling technology. XING explains that current battery cells are at risk of overheating when rapidly charged and discharged. No matter how powerful the motors, maximizing the power density of an electric drivetrain is extremely difficult with the current cooling and enclosure options on the market.

The XING Battery System consists of stackable, LEGO-like battery modules housing 42 lithium-ion cells, all of which sit directly in a reservoir of 3M Novec 7200 Engineered Fluid, a non-conductive fluid designed for heat transfer applications, fire suppression and supercomputer cooling.

“The use of Novec Engineered Fluids to immersion-cool EV batteries is a breakthrough application, addressing the critical performance needs of the market in a new and disruptive way,” said 3M’s Michael Garceau.

Miss R has undergone a series of initial tests, and XING plans to reveal a completed prototype in late 2018. The company will build just 20 of the supercars, which it intends to make available in 2019 starting at $1 million.

The company is working with commercial and industrial vehicle makers to apply the XING Battery System in city buses, ride-sharing scooters, construction vehicles and boats. “The industrial vehicle market is primed for a conversion to electric drivetrains due to functional needs, increasing emissions requirements and public noise reduction,” said XING co-founder and CTO Azizi Tucker. “However, this market is currently extremely fragmented and revolutionizing much slower than what we’re seeing in the passenger car market. The XING Battery System is an opportune solution for small- to medium-volume vehicle makers, catering to a huge variety of shapes, sizes and power requirements.”
