摘要： A system for detecting thermal events, e.g., thermal runaway, within a sealed battery pack based on a characterization of monitored pressure variations within the pack is provided. The system includes at least one pressure sensor coupled to the battery pack and to a pressure monitoring system that outputs pressure data representative of the battery pack pressure over time; a system controller that analyzes the pressure data and outputs a control signal when the pressure data fits a specific curve shape; and a thermal event response subsystem that performs a preset response upon receipt of the control signal from the system controller. The system may include a secondary effect monitoring system, wherein the thermal event response subsystem performs the preset response when the pressure data fits a specific curve shape and the secondary effect is detected by the secondary effect monitoring system.

摘要： A method for detecting and responding to a battery thermal event within a sealed battery pack is provided. The method includes the steps of monitoring and characterizing the pressure within the battery pack over time, where identifying a battery thermal event is based on the pressure data fitting a specific curve shape, and performing a preset response when a battery thermal event is identified. The method may additionally monitor for a secondary effect associated with the battery thermal event.
