  • Patent number: 11721858
    Abstract: Batteries and other devices heat during operation and must be cooled to optimal temperatures. Our SuCCoR method differs from the previous thermal management systems by keeping batteries and devices continuously immersed in a coolant bath kept in a sealed enclosure at its supercritical fluid (SCF) and/or a neighboring thermodynamic state with superb heat conducting properties. While many previous inventions circulated coolants, and some kept devices sealed in a fluid, our invention differs by its use of SCF coolants with no distinct liquid and gas phases. Such a single-phase coolant prevents abrupt loss of cooling due to “vapor lock” formation. Also, using an outer jacketed vessel and a network of heat conducting pipes containing high thermal conductivity and high heat capacity coolants, and deploying cooling fins will enhance efficiency and accelerate heat removal. Our system avoids complex pumps to circulate the coolants, and is lighter and cheaper.

  • Patent number: 11217857
    Abstract: A system comprising one or more battery modules mounted in a rack assembly has a structure which defines a cooling air pathway for flowing cooling air across the side and/or bottom of each battery module thereby cooling the battery module, or alternatively, across the energy calls in the battery module. Further, the system has a structure which defines a thermal runaway gas pathway for flowing thermal runaway gases from a battery module out of the system. The system structure is configured to ensure that the cooling air pathway and thermal runaway gas pathway are physically separated, thereby minimizing the risk of the thermal runaway gas substantially mixing with cooling air thereby potentially resulting in a spontaneous ignition and an explosion.
