Eco-friendly electric vehicles EV, HEV, PHV have rapidly penetrated the market as social awareness towards environmental protection increased over the years. EVs equipped with high-voltage battery requires anti-electrification and secondary disasters in case of traffic accidents and malfunctions. Pyro-Fuse could also be utilized not only for EVs but also any industrial applications in need of instant circuit isolation. Product customization is also available based on usage environments and voltage requirements. Please contact us for details. When the signal is detected from the vehicle, an ignition current is generated to operate the Pyro-Fuse, shutting down the circuit and preventing electrical flow.

Whether you're talking about gallons of combustible fuel or explosive airbag inflators, potentially dangerous items are commonplace in cars. Bosch is taking this old idea to electric vehicles with a new technology designed to make batteries safer in a crash. And it includes a component with a cool name: pyrofuse. That sounds. According to Bosch, this is how you keep an electric or hybrid vehicle's batteries safe. The Bosch-developed system uses tiny, controlled explosive charges on an EV's battery to isolate the power supply if there's a collision. When the car's sensors detect a crash, the pyrofuse technically known as a pyrotechnical safety switch system will use its miniature explosive charges to physically blow apart sections of wiring between the high-voltage battery unit and the rest of the vehicle with up to four small wedges.

Pyrotechnics for safe e-Mobility. The transition to electric vehicles brings with it the need for new safety systems. The system disconnects the battery or the DC charger in case of emergency such as accident, crash or short circuit, reducing possible dangers and risks for passengers, rescue teams and first aiders. It has an ultrafast response speed below one millisecond and breaks the power supply immediately. Further benefits are the low weight and the cost efficient design and the ability to disconnect short circuit currents without outburst of conductive and hot gases. In addition, the system is also available with an integrated current sensor, saving costs, space, and assembly efforts and simplifying component harmonization. With the ongoing transformation to e-mobility and new market demands, pyrofuse systems will be widely used in electric vehicles and this technological segment will undergo rapid development. Rheinmetall, with its position of an innovation leader, will continue to expand its advantages and drive further technological progress in the field of mobility and security.
