Power To Electric Heating Circuits TRIZ Cases
- PTC Heating Element Contacts for Thickness Variation Tolerance
Contact projections on strip conductors maintain reliable PTC current transfer despite thickness variation, reducing sparks and thermal disturbance.
- Battery Thermal Circuit Using Drive Unit Waste Heat
Vehicle battery warming uses excess heat from a drive or charging unit, cutting dedicated heater weight, size, and control complexity.
- Dual Power Supply Switch Control for Noise-Robust Fault Isolation
A latched pulse disconnect scheme isolates the faulty power system despite noise, avoiding repeated switching and preserving fail-safe stored power.
- Drive Axle Battery Thermal Control Across Charge, Park, and Drive
Temperature-threshold control heats or cools the drive axle power source by operating mode, cutting thermal energy waste while protecting reliability.
- Vehicle Power Supply Isolation During Battery Voltage Drops
Voltage-drop detection isolates noncritical vehicle circuits so capacitive reserve power can finish memory writes and protect transistors.
- Vehicle Traction Battery Layout With Diode-Based Voltage Equalization
Diode-fed auxiliary loads draw from the higher-voltage battery, balancing charge states and cutting converter losses in vehicle traction systems.
- Vehicle Onboard Voltage Stabilization via Dynamic Switching
A control unit dynamically connects a storage unit in series with a voltage supply to stabilize onboard vehicle power.
