Hyundai Mobis announced it has developed new technology designed to automatically suppress electric vehicle battery fires by spraying fire extinguishing agents directly onto ignited battery cells. The system aims to prevent thermal runaway by blocking heat transfer to adjacent cells, a technology the company believes is not yet commercially available worldwide.
Battery System Design Focuses on Heat Resistance
The battery system is engineered to resist heat and flames, utilizing heat-resistant materials to contain the source of the fire. This growth comes as major markets, including Europe, China, and India, mandate a minimum five-minute delay in thermal runaway after a battery cell’s initial ignition. Some regions are also strengthening regulations to prevent thermal runaway altogether.
Hyundai Mobis anticipates its battery system assembly (BSA), featuring cell-level fire suppression, will gain prominence as a next-generation safety technology in the global market.
BSA Components and Functionality
The BSA developed by Hyundai Mobis comprises a battery management system (BMS), a fire extinguishing device, a battery case, and software to control the system.
The BMS analyzes battery temperature, voltage, and internal system pressure using real-time sensor data to detect early signs of abnormalities.Upon detecting ignition, the system identifies the precise location and triggers the fire extinguishing device.
Software Logic for Rapid Response
The software is designed for fast and accurate assessment,enabling it to respond to physical changes within the battery system. Hyundai Mobis emphasizes the system’s reliability through the implementation of multiple safety devices and redundant algorithms.
Fire Suppression system Details
The battery system contains a fire extinguishing agent with five times the capacity of a standard 3.3 kg household fire extinguisher.According to Hyundai Mobis, the agent possesses excellent cooling, insulation, and penetration properties while remaining environmentally safe and harmless to humans.
Patents and Design
Hyundai Mobis has filed for three domestic and international patents related to this technology, covering the battery case and fire extinguishing devices.The design incorporates specialized piping for dispensing the fire extinguishing agent under high pressure.
“As electric vehicles with improved mileage become more common, the safety standards for battery systems are becoming more stringent,”
Additional Heat Management Technology
Hyundai Mobis also developed new materials last year to prevent battery overheating and is working toward commercialization. This material,a vibrating heat pipe composed of aluminum alloys and refrigerants,is placed between battery cells to reduce internal temperatures during rapid charging. The company expects this technology to provide stable heat management, even during fast charging.
Hyundai Mobis’s EV Fire Suppression Technology: Your Questions Answered
What is Hyundai Mobis’s New Battery Fire Suppression Technology?
Hyundai Mobis has developed a new technology designed to automatically suppress electric vehicle (EV) battery fires. This system directly sprays fire extinguishing agents onto ignited battery cells to prevent thermal runaway and contain the fire.This technology is aimed at enhancing EV safety, especially with rising safety standards in major markets.
How Does the Hyundai Mobis Battery Fire Suppression System work?
- Early Detection: A Battery Management System (BMS) monitors battery temperature,voltage,and internal pressure using real-time sensor data.
- Ignition Detection: The BMS identifies any abnormalities, and upon detecting ignition, pinpoint the fire’s location.
- Fire Suppression: The fire extinguishing device is triggered, spraying a specialized agent directly onto the affected cells.
- Containment: The system is designed to prevent heat transfer to adjacent cells,thus preventing the fire from spreading
What are the Key Components of the Hyundai Mobis BSA (Battery System Assembly)?
The hyundai Mobis Battery System Assembly (BSA) is comprised of:
- Battery Management System (BMS): Monitors and analyzes battery conditions.
- Fire Extinguishing Device: sprays the fire extinguishing agent.
- Battery Case: Provides structural support and containment.
- Software: Controls the system’s operation and rapid response.
what Fire Extinguishing Agent Does Hyundai Mobis Use?
The system utilizes a fire extinguishing agent with five times the capacity of a standard 3.3kg household fire extinguisher.This agent has demonstrated excellent
cooling, insulation, and penetration properties. Furthermore, it’s designed to be environmentally safe and pose no harm to humans.
What is Thermal Runaway and Why is Preventing it Vital?
Thermal runaway is a chain reaction in a battery cell where heat leads to more heat, causing the battery to ignite and potentially spread fire to other cells. Preventing thermal runaway is crucial for EV safety. New regulations in regions like Europe, China, and India mandate a delay of at least five minutes after initial ignition to allow time for fire suppression and containment.
What Other Heat Management Technologies is Hyundai Mobis Developing?
Hyundai Mobis also developed new materials, specifically a vibrating heat pipe made of aluminum alloys with refrigerants.This heat pipe is placed between battery cells to reduce internal temperatures during rapid charging. It aims to provide stable heat management, even during fast charging, helping to prevent overheating.
What Patents Does Hyundai Mobis Hold for This Technology?
Hyundai mobis has filed for three domestic and international patents related to this technology,specifically covering the battery case and fire extinguishing devices. The design includes specialized piping to dispense the fire extinguishing agent under high pressure.
