A recently granted patent (Publication Number: US11881571B1) discloses an innovative apparatus designed for thermal management in vehicles powered by battery apparatus. The apparatus includes a body with a channel that couples with the battery apparatus and a conductor electrically coupled to a ground. The conductor features a lead into the channel to ground the coolant within, which is responsible for cooling the battery apparatus. The design also incorporates various components such as a bulkhead fitting, conductive materials, and connectors to ensure effective grounding of the coolant for optimal thermal management.

Furthermore, the patent extends to a thermal management system and a sensor, both utilizing similar principles of grounding coolant to facilitate battery cooling in vehicles. The thermal management system includes a connector with a channel and a conductor for grounding the coolant, while the sensor features a body that extends into a channel with a conductor coupled to the body for the same purpose. These systems offer a comprehensive approach to thermal management in vehicles, ensuring efficient cooling of the battery apparatus to enhance overall performance and longevity. The incorporation of innovative design elements such as over-molded conductors and prismatic-shaped components showcases a commitment to technological advancement in the field of battery-powered vehicle systems.
