Electric Devices TRIZ Cases
- Battery Insulation Monitoring Circuit for Dormant Vehicle Detection
A closed-loop pulse circuit enables real-time battery insulation monitoring during vehicle dormancy without BMS control.
- Vehicle Inverter Connector Layout to Shield High-Voltage Terminals
A rearward, downward-facing cable mount layout makes vehicle high-voltage terminals harder to touch while preserving connector access.
- Secondary Battery Authentication Using Pause-Period Voltage Curves
Voltage analysis across pause, charging, and discharging periods improves detection of genuine secondary batteries.
- In-Vehicle Battery Impedance Diagnosis Using Pulse Current Profiles
Pulse current profiles let onboard battery systems calculate cell impedance and flag health faults without lab analyzers.
- Railcar Auxiliary Power Monitoring for Sequential Device State Recording
Sequential start-stop control lets a railcar auxiliary power supply capture voltage and current data from both active and idle in-vehicle devices.
- EV Active Discharge Circuit Self-Diagnostics During Shutdown
A sensor and control loop checks whether an EV active discharge circuit responds during shutdown, flagging deficient DC link capacitor discharge.
- Rear-Side Battery Pack Structure With Integrated Impact and Airflow Path
A rear collision impact reducer doubles as a battery cooling air path, protecting the pack while cutting parts and structure complexity.
- Wheel-Side Suspension Layout for Simpler Drive Wiring and Steering
Relocating the drive mechanism to the suspension arm simplifies actuator wiring and piping while removing steering links for easier maintenance.
- Battery State-of-Health Prediction with Sparse Ageing Data
Linked ageing-time functions predict battery state of health from limited early data, improving degradation tracking and remaining life estimates.
