The great danger of electric cars are the fires that originate in their batteries. Although the rate of these accidents is minimal, manufacturers try to find more stable chemicals to avoid these events. But those of the JOB Group have developed what is the smallest fire extinguisher in the world, capable of putting out a fire inside the batteries.
One of the big problems facing the industry in the electric cars are fires that originate in batteries. The rate of these unfortunate events is minimal, not reaching 30% worldwide, but they are so complicated to turn off that they practically destroy the car completely. Unstable chemicals, cells in poor condition since factory assembly, accidents and high temperatures in some cases they are the ones behind the causes of the fires.
Electric car manufacturers and suppliers face an important challenge, that of guaranteeing that fires will not occur in this component, something difficult to overcome. But those of JOB Group they have taken out of the sleeve the one who is the world’s smallest fire extinguisherand whom they have baptized as «eBulb». The developer has carried out important tests with these small blisters, earning it the award for innovation in safety that it obtained two years ago, and which it now offers to interested electric car manufacturers.
This is how JOB e-Bulb works, the world’s smallest fire extinguisher for electric cars
The JOB e-Bulb prevents fires in electric batteries
On these lines you can see an example of its operation on a smaller scale, but basically it is about small ampoules filled with a non-toxic, non-flammable liquidcalled «3M Novec», which are inside a refractory plastic fuse, and which is installed on printed circuit boards connected to a sensor that is capable of detecting a high temperature inside a battery. It even has the ability to detect even near misses, the beginning of a more important fire.
JOB e-Bulb fire extinguisher explodes when reached a maximum temperature of 165º C inside the battery, a moment of overheating in which the thermal management system that all electric cars are equipped with cannot detect a fault, which ends up causing a reaction. That’s when the world’s smallest fire extinguisher converts the liquid it contains into a gas and puts out the fire by acting as a cooler for the battery cells reducing oxygen.
The system has an added function, a true key for firefighters who, in their studies, have determined that one of the great problems for extinction is reactivation, which forces the vehicle to be immersed in a giant container of water for at least 24 hours to be able to turn it off completely. And it is that the system also activates a function of interruption of electricity supply, so the battery is deactivated completely. The managers of the company have already pointed to their commercialization in 2024hoping that the brands will take the hint and install this device in the batteries, avoiding great annoyances to the owners.
