Application: Thermal mitigation systems for traction battery packs (Patent ID: US20240213565A1)
The patent filed by Ford Motor Co. describes thermal mitigation systems for traction battery packs. These systems include cartridges containing nitrogen releasing materials and heating elements that can actively mitigate battery thermal events by releasing nitrogen gas. Additionally, passive release devices mounted to a battery array are described, where a nitrogen releasing material within the device can be activated by heat generated within the battery array to passively mitigate thermal events.
The thermal mitigation system includes various components such as a controller to control the release of nitrogen gas, specific nitrogen releasing materials like guanidine nitrate or sodium azide, and vent patches to release gas when pressure thresholds are exceeded. The systems can be actively controlled by a 12V controller circuit or passively activated by heat within the battery array. The passive release devices are designed with polymeric encapsulating materials that break open to release nitrogen gas when temperatures exceed predefined thresholds, providing a comprehensive approach to managing thermal events in traction battery packs.
