Safeguarding Energy Storage Solutions

At Stopyr, we design products for thermal runaway detection that incorporate an array of gas sensors to detect early traces of gases, ensuring timely intervention. Our system logs sensor data locally and uploads it to the cloud, where advanced AI performs trend analysis. This allows the system to learn its environment and prevent false alarms, ensuring reliability and accuracy.

Driven by innovation and a commitment to excellence, Stopyr is dedicated to providing top-tier safety solutions for Battery Energy Storage Systems (BESS). Our mission is to safeguard both consumers and businesses with our cutting-edge technology.

Thermal runaway is a critical issue in battery technology, posing significant risks to safety and reliability. It occurs when a battery cell enters an uncontrollable, self-heating state, leading to potential fires or explosions. This phenomenon can be triggered by various factors, including:

• Overcharging: Excessive charging can cause internal short circuits, leading to overheating.
• Physical Damage: Impact or puncture can compromise the battery's integrity, initiating thermal runaway.
• Manufacturing Defects: Flaws in the production process can result in unstable battery cells.
• Environmental Conditions: Extreme temperatures and improper handling can exacerbate the risk.

The consequences of thermal runaway are severe, affecting various industries:

• Consumer Electronics: Incidents of smartphones and laptops catching fire have raised concerns among users and manufacturers.
• Electric Vehicles (EVs): The growing adoption of EVs highlights the need for robust safety measures to prevent catastrophic failures.
• Energy Storage Systems: Large-scale battery installations for renewable energy storage must ensure safety to gain public trust and regulatory approval.

Traditional detection methods primarily rely on monitoring temperature increases, which are often managed by the Battery Management System (BMS). However, these methods have significant limitations:

• Delayed Response: Temperature sensors typically detect thermal runaway only after a significant temperature rise has occurred, which may be too late to prevent damage.
• Limited Sensitivity: These sensors may not pick up subtle early signs of thermal instability, leading to delayed intervention. Additionally, they are often placed in only certain areas of the battery pack, making it difficult to reliably monitor all cells.
• BMS Dependency: Relying solely on the BMS for battery health monitoring can result in missed early warning signs, as the BMS may not be equipped to detect all potential issues.
