Electric Devices TRIZ Cases
- EV Power Supply Interlock Mechanism for High Voltage Safety
A power supply system uses an interlock member to control a switch device that interrupts electrical connections between a battery and a connector.
- Safety-Critical Vehicle Actuator Voltage Boosting
A safety-critical vehicle actuator signals an alternator to output raised voltage upon activation.
- Enthalpy-Based Energy Usage Analysis Across Facilities
Central system calculates enthalpy from temperature and humidity to model facility energy usage.
- Adaptive Isolation Fault Testing for Multi-String EV Batteries
A battery management circuit controls switches to test individual battery strings within dedicated time windows.
- Fuel Cell Stack Diagnosis via Stepwise Current and Fourier Analysis
A fuel cell stack diagnosis apparatus extracts reference voltage points from stepwise current changes to form a reference signal waveform for abnormality detection.
