Needs review: this page currently has no cited references for its technical claims or for the vehicle examples listed (BMW i3, Mercedes S400 Hybrid, BYD Blade 2.0). Sourcing and expansion (e.g. typical refrigerant loop architecture, comparison of performance/cost vs. indirect water-glycol cooling) would strengthen it.
The cells are thermally connected to a refrigerant cooling plate. This is seen as less complex in the automotive industry as it removes the intermediate water-glycol system and applies the refrigerant system directly to the cells. Thus removing a number of parts, making it possibly cheaper and lighter.
Examples: BMW i3, Mercedes S400 Hybrid, BYD Blade 2.0
