Cells Structural Combination TRIZ Cases
- Battery Draw Monitor Using a Shunt for Accurate Parasitic Current Testing
A shunt-based monitor measures automotive parasitic draw up to 100 amps accurately without circuit switching, reducing false positives and downtime.
- Battery Module Voltage Sensing for Thermal Runaway Detection
Voltage comparison across battery cells and the module detects thermal runaway without separate temperature sensors, cutting cost and complexity.
- Battery Bypass Circuit for Low-Current Machine Tool Wake-Up
A comparator-controlled bypass circuit supplies low wake-up current in idle mode while preserving battery energy for machine tools.
- Hybrid Battery Interconnects for Stronger Dissimilar-Tab Welds
A two-metal interconnect matches aluminum and copper tabs separately to improve weld quality and electrical reliability in battery submodules.
- Plastic End-Plate Battery Pack for Cell Expansion and Pressure Relief
Plastic end plates absorb cell expansion and support gas discharge, helping compact battery packs handle higher current with better heat control.
- Coin Battery Module Support Structure for Thin PCB Shock Resistance
A case body inserted through the PCB supports coin-cell weight, protecting electrode plates and maintaining shock resistance in thin-board modules.
- Wireless Battery Charge Monitoring for Timely Replacement
Wireless battery signals reveal charge status remotely, helping users replace depleted batteries in time and find compatible replacements.
- Battery Board Temperature Estimation Without Cell Sensors
Charge-discharge and board temperature data are combined to estimate cell temperature inside battery boards without adding sensors to each device.
- Battery Tray Leak Detection Through Bus Bar Resistance Sensing
A high-voltage conductor and BMS track resistance changes in the tray to detect coolant leaks before insulation faults or gas release.
- Layered Pouch Battery Pack Layout for Cooling and Cell Monitoring
Layered pouch cells use cooling side walls and separate BMC placement to improve space use, heat dissipation, and pack reliability.
- Power Switch Buffer Circuit for Battery Heating Peak Voltage Control
RCD buffer units create a short-time switching path that limits peak voltage and overheating in battery heating power switches.
