Subject: [EVDL] EVLN: Coolant immersed cells for XING EV's Modular Battery 
New approach to electric-car battery cooling: immerse cells in coolant Dec 8,

XING Miss R Lithium-Ion Battery Pack
XING Modular Battery System

Regardless of how your vehicle is powered—whether it be an internal-combustion 
engine or a battery pack powering an electric motor—most powertrains have a 
common enemy: heat.

For Taipei-based XING Mobility, heat is a major concern for its 
high-performance Miss R model as its battery cells need to rapidly discharge to 
generate its maximum quoted output of 1,000 kilowatts (1,341-horsepower).

The more rapidly you discharge a battery, the more heat it generates—and XING 
believes it has a solution to keep its fast-discharging battery pack cool.

Instead of snaking coolant through lines and chambers within the battery pack's 
case, XING is taking a wholly different approach by immersing its cells in a 
non-conductive fluid with a high boiling point.

According to Charged EVs, the coolant is 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 to Charged EVs.

XING's batteries take the form of 42 lithium-ion-cell modules that can be put 
together to build larger battery solutions.

For the XING Miss R, the complete battery houses 4,200 individual 18650 
lithium-ion cells encased in liquid-cooled module packs.

While XING plans to use the battery packs for its own vehicles, it said it will 
also sell the battery solutions to other OEMs looking for energy storage

“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.

"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 

XING also plans to offer other off-the-shelf components for fledgling EV 
makers, such as torque-vectoring gearboxes, electric power kits, and 
magnetorheological dampers.

The company projects its Miss R model should be capable of sprinting to 100 
km/h in 1.8 seconds, reaching 200 km/h in 5 seconds, and hitting a top speed of 
270 km/h (168 mph).
