PREVENTING PROPAGATION OF CELL FAILURES IN BATTERY PACKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18442872 titled 'PREVENTING PROPAGATION OF CELL FAILURES IN BATTERY PACKS
The patent application describes battery packs for vehicles that include multiple battery cells, flow control devices, and sensing and control circuitry. This circuitry is designed to measure parameters indicating the onset of thermal runaway in the cells, identify cells at risk of thermal runaway, and activate flow control devices to cool the cells or vent media following a thermal runaway event.
- Battery packs for vehicles with advanced safety features
- Sensing and control circuitry to detect thermal runaway in battery cells
- Flow control devices to cool cells or vent media post-thermal runaway
- Enhanced safety measures for battery packs in vehicles
- Integration of cooling mechanisms to prevent thermal runaway events
Potential Applications: - Electric vehicles - Hybrid vehicles - Energy storage systems
Problems Solved: - Mitigating the risk of thermal runaway in battery packs - Enhancing safety in vehicles using battery packs
Benefits: - Improved safety in vehicles - Prevention of thermal runaway events - Extended lifespan of battery packs
Commercial Applications: Title: Enhanced Safety Battery Packs for Vehicles This technology can be used in electric and hybrid vehicles to improve safety standards and prevent thermal runaway incidents, making it an attractive feature for consumers and manufacturers alike.
Questions about Battery Packs with Advanced Safety Features: 1. How do flow control devices help prevent thermal runaway in battery cells? Flow control devices are activated to cool the cells or vent media following a thermal runaway event, reducing the risk of further damage or safety hazards. 2. What are the potential implications of integrating sensing and control circuitry in battery packs for vehicles? Sensing and control circuitry can significantly enhance the safety and performance of battery packs in vehicles, leading to increased consumer trust and adoption of electric and hybrid vehicles.
Original Abstract Submitted
Battery packs, which may be used in vehicles, include: a plurality of battery cells; one or more flow control devices; and sensing and control circuitry configured to: measure one or more parameters indicative of an onset of thermal runaway of one or more of the plurality of cells; determine, based on a change in one or more of the measured parameters, that one or more of the plurality of battery cells has begun or is at risk of beginning thermal runaway; and activate one or more of the flow control devices in response to the determination. Each of the one more flow control devices is configured to, when activated, direct a flow of fluid past one or more of the plurality of cells to cool the cells and/or carry media vented by one or more of the cells following a thermal runaway event away from the one or more cells.
