Battery Cutoff Switches TRIZ Cases
- Circuit Breaker Housing Structure for Arc Gas Leak Suppression
A split inner-outer housing structure resists heat and impact during conductor cutoff, limiting cracks and arc gas leakage after actuation.
- Pyrotechnic Circuit Breaker Chamber Material for Low Leakage
Silicone-based chamber walls improve post-opening insulation resistance in a pyrotechnic circuit breaker while limiting leakage currents.
- Circuit Breaker Arc Quenching With Guided Gas and Wire Mesh
Guided hot gas is driven through a wire-mesh arc chamber to improve high-current interruption and insulation after conductor severing.
- Pyrotechnic Busbar Breaker With Dual Triggering and Arc Extinguishing
A fused busbar breaker combines passive overcurrent and active external triggering in one punch-mounted igniter to cut current and extinguish arcs.
- Capacitor-Backed Activating Current for HV Battery Disconnects
A pre-charged capacitor and diagnostic monitoring keep pyrotechnic battery disconnects working during crashes when the main battery drops out.
- Shearable Conductor Switch for High-Current Arc Interruption
A shearable conductor and insert layout lets a small actuator open high-current paths quickly while reducing arc severity and switch bulk.
- Pyrotechnic Switch Conductor Cutting With Symmetrical Free Strands
Multiple cut points create symmetrical free strands that stabilize conductor separation, reduce arcing, and improve switch reliability.
- MOSFET Pyrofuse Triggering Circuit for Fast Multi-Fuse Isolation
Precharged capacitors and a MOSFET stage deliver fast, reliable current pulses for simultaneous pyrofuse triggering in energy storage systems.
- Pyrotechnic Contactor Interrupter for Fast Overcurrent Isolation
A pyrotechnic plunger opens the contact bridge in under 2 ms to stop extreme overcurrent and prevent contactor re-closure.
- Pyrotechnic Circuit Breaker Fuse Switching for Wide Current Interruption
A threshold-triggered fuse connection lets a pyrotechnic breaker interrupt both low- and high-intensity currents while preventing arc reestablishment.
- Pyrotechnic HV Switch-Off with Arc Quenching for Vehicle Faults
A pyrotechnic separator redirects fault arcs to a melting conductor, enabling reliable HV current interruption and fire prevention in vehicles.
