EV Battery Ejection System: A Controversial Safety Solution

In the presentation video clip, they show the pack being jettisoned from below the vehicle with a bang. The system is created to fire the pack between 10 and 20 feet (3 and 6 meters) away from the vehicle, where emergency crews could handle it much easier than if it were still concealed in the underbelly of the vehicle.

Novel EV Safety Concept

China goes to the forefront of EV technology, particularly when it involves charging and battery technology, and it’s additionally looking at applying novel means of making electrical lorries safer. One concept that was lately offered by the Chinese Car Crash Repair Work Technical and Research Center, in collaboration with Joyson Electronic devices, takes this security technology to an extremely weird location.

The video has actually been shared on a selection of Chinese social networks platforms, and is currently going somewhat viral below in the West. InsideEVs is attempting for more information about the video’s provenance and the technology apparently at the workplace here.

Concerns and Potential Dangers

In its current kind, it couldn’t possibly be approved, because it would pose a major danger to other cars or nearby pedestrians. A significant smoldering battery pack considering thousands of extra pounds hurtling via the air can do a great deal of damages, and as shown in the video, this appears like more trouble than it deserves.

Addressing EV Battery Fires

While it could be easy to poke fun at such an option, it at the very least attempts to find a remedy to EV battery fires. They are remarkably tough to put out, so in many areas in Europe, when emergency situation staffs are called to take care of a burning EV, they might roll up a significant water storage tank into which they immerse the car to make sure the fire is put out and that it doesn’t reignite.

While it could be very easy to poke fun at such a remedy, it a minimum of looks for a solution to EV battery fires. They are remarkably hard to put out, so in several areas in Europe, when emergency crews are phoned call to handle a burning EV, they might roll up a massive water storage tank into which they immerse the vehicle to make sure the fire is put out and that it doesn’t reignite. It will in fact maintain shedding undersea too, with temperature levels getting to over 1,800 ° F (1,000 ° C).

Future Improvements and Considerations

However if an evolution of this system would certainly work with the sensing units and electronic cameras around the car, even make use of artificial intelligence to understand what’s about, there may be something to this idea. The lorry would certainly additionally require to be able to manage the pressure of the battery ejection, and even its direction, to decrease the risk of it triggering damage or injuries around it.

Thermal Runaway Explained

Once one cell inside the pack fires up, it sets off a chain reaction that spreads out from cell to cell and is exceptionally tough to quit. This is referred to as thermal runaway, and scientists from around the globe are looking at ways to avoid it or minimize its impacts and keep occupants inside EVs safe.

Having just the battery pack to produce and not the whole lorry increasing in flames ought to make it much easier to put out. Nonetheless, what you see in the video clip resembles the product of a very early idea that still requires improvement to make it into a manufacturing automobile.

They demonstrated an automated system that shoots the battery from beneath the automobile less than one second after it identifies that thermal runaway has occurred. This makes a lot of sense since it keeps the auto itself from burning down and the passengers inside secure, however it’s likewise quite alarming and potentially unsafe.
