摘要： Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on an external charger comprising charger fluidic ports and sliding the swappable battery module to the charger fluidic ports until these charger's ports are fluidically coupled with the module's fluidic ports. Specifically, the external charger comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the charger base depending on proximity of the first end plate to the charger base.
