A Breakthrough Pyro Safety Module For Safe E-Mobility
Product Demo
Recorded Sep 1, 2020 10:15 am EDT
Hirtenberger Automotive Safety and Littelfuse plan to jointly develop an integrated, active and passive Pyro Safety Module (PSM).
This PSM combines the advantages of pyro-, fuse-, and sensor technologies in a synergetic way.
Pyro-Breaker is known for very fast and reliable circuit interruption up to high breaking capacities. Fuses take advantage of melting metals when high currents generate ohmic heating, consequently creating a current/time characteristic which interrupts fault currents fully passively (no external power is needed). Finally, current sensors allow not only to measure a current signal accurately, but they also can be expanded to send a trigger signal to the Pyro-Breaker allowing current-time characteristics independently of the physics of melting metal.
The integration of these 3 components into one module results in:
- the combination of its characteristics and capabilities
- very significant footprint reductions
- reduction of electrical losses and heating
- increase in reliability when compared to 3 discrete components
This presentation will discuss the principles, options, and advantages of Pyro Safety Modules.
