An ultra high pressure (UHP) extinguishing system holds the key to safely and effectively extinguishing the unstable or burning battery packs of electric vehicles. When certain safety measures are in place, this system proves to be a valuable addition to the fire department's arsenal. It offers an alternative to traditional methods like water-filled submersion containers or letting the vehicle burn out.

Unlock the Power of UHP in Electric Vehicle Firefighting

Direct Cooling of Battery Cells with UHP Technology

The UHP-extinguishing system utilizes ultrahigh pressure water jet technology. This enables the creation of an opening in the battery pack, allowing direct water injection. As a result, the thermal runaway in the battery can be stabilized on-site, providing a crucial means of controlling the fire. 1: By using this advanced technology, firefighters can quickly and efficiently target the source of the fire within the battery pack. The high-pressure water jets penetrate deep into the cells, cooling them down and preventing further damage. This direct approach not only saves time but also increases the chances of successfully extinguishing the fire. 2: The ability to cool the battery cells directly with UHP technology is a significant advantage. It allows for a more targeted and effective firefighting response, reducing the risk of secondary explosions and minimizing damage to the vehicle and its surroundings.

Safety Measures for UHP Extinguishing System Deployment

When deploying the UHP-extinguishing system, several safety measures must be followed. 1: Firstly, low-pressure jets are used to suppress flares from the battery and protect the UHP operator. This helps to ensure the safety of those involved in the firefighting operation. Secondly, any accumulated flammable gases in the vehicle are ventilated by braking the windows with the UHP-extinguishing system from a distance or using fans. This prevents the spread of the fire and reduces the risk of explosion. 2: Additionally, firefighters are positioned away from (toxic) smoke and protected with low-pressure jets if necessary. The use of the long lance or extension of the UHP-extinguishing system also enhances safety and allows for better access to the battery pack.

Clear Deployment Procedure for UHP Extinguishing System

The UHP-extinguishing system operational guidelines involve locating hot spots with a thermal imaging camera, penetrating the battery pack at these locations, and introducing water via the UHP-extinguishing system. 1: Steam formation serves as an indicator that the batteries are cooling. The leakage of water out of the battery pack, combined with the cessation of steam formation, indicates that the thermal runaway has stopped. This clear deployment procedure provides firefighters with a reliable method for assessing the effectiveness of the UHP-extinguishing system. 2: Firefighters who participated in the fire experiment have expressed positive feedback about the deployment of the UHP-extinguishing system. They believe that the method is relatively easy to implement and provides a more efficient way to handle electric vehicle battery fires.

Collaboration for Research and Development

The fire experiment was made possible through the collaboration of various parties, including Fire Brigade Netherlands, Fire Brigade Schiphol, Joint Fire Brigade Rotterdam, Company Fire Brigade Tata Steel, Safety Region Utrecht, and Safety Region Haaglanden. 1: In addition, the German working group VDA/VDIK 'Rescueing of people', Cobra Coldcut Systems, and the car supplier are also contributing to the research. This collaborative effort ensures that the UHP-extinguishing system is constantly evolving and improving to meet the challenges of electric vehicle fire safety. 2: By working together, these organizations are able to share knowledge and expertise, leading to the development of more effective firefighting solutions. The collective efforts of these parties are crucial in ensuring the safety of electric vehicle users and the public.
