Electrical Energy Store and Method for Monitoring an Electrical Energy Store

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an electrical energy storage device (such as a battery pack) that includes one or more cells and uses strain gauge units to detect deformations in the cells. The deformation is measured along a specific direction, and such measurements allow early detection of potential faults or dangerous conditions, such as gas formation or swelling in the cells, which can lead to failure or hazardous events. The system can trigger alerts or modify battery operation in response to detected changes, thereby improving safety and reliability.

Use CasesContent extracted from patent full text and abstract with AI.

• Battery health monitoring in electric vehicles to prevent failures and ensure safety
• Early fault detection in stationary energy storage systems for renewable energy integration (solar, wind, etc.)
• Monitoring of industrial battery backup systems to avoid downtime or damage
• Consumer electronics (laptops, smartphones) battery safety and longevity management
• Aerospace and defense applications where early detection of battery cell failure is critical

BenefitsContent extracted from patent full text and abstract with AI.

• Enables early detection of battery cell faults such as swelling, gas formation, or thermal runaway, reducing risk of catastrophic failure
• Enhances overall battery safety for various applications, including automotive and stationary systems
• Allows for real-time monitoring and preventive action (stopping charging, issuing warnings, etc.), minimizing damage and hazards
• Can function even when the main system is not operating (e.g., parked vehicles) owing to its low energy consumption
• Improves reliability of energy storage systems by providing continuous and robust diagnostic information
