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.
Daicel Safety Strategic Business Unit(SBU)s' Pyro-Fuse enables safe, instantaneous shutdown of high-voltage electric currents.
Pyro-Fuse could also be utilized not only for EVs but also any industrial applications in need of instant circuit isolation.
Daicel Safety Strategic Business Unit(SBU)s' have developed Pyro-Fuse that enables safe, instantaneous shutdown of high-voltage electrical currents.
Product customization is also available based on usage environments and voltage requirements.

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.
Instant electrical shutdown is realized based on the high reliability cultivated in the Inflator field.
Daicel Safety Strategic Business Unit(SBU)s' have developed Pyro-Fuse that enables safe, instantaneous shutdown of high-voltage electrical currents.
We provide broad application of Pyro-Fuse requirements that could be used for not only electric vehicles, but also gasoline vehicles as well.
Protection from overcurrent due to short circuits and malfunctions.
Protection from electric shocks and fire by isolating the battery in case of car crashes.
Protection from fire due to overcharging.
Safe electrical shutdown on a millisecond level could also be utilized in systems used for industrial power storages, heavy-duty batteries, recyclable energy storages, and electricity transmissions.
Shutting down emergency overcurrent.
Controlling battery charging to prevent overcharge.
