Pyro-Triggering

The potential energy in the high voltage battery can cause severe damage to critical components of the energy storage and management systems. As a result, extremely fast circuit interruption capability is a critical need of modern electric vehicles. Littelfuse pyro triggering devices, with customizable current thresholds and triggering times, offer the capability to trigger the pyro-fuse in one third the time as is typical by an over-current detection signal from a current sensor alone.
