Texas Instruments introduces TMCS2100-Q1 sensor aimed at improving EV traction inverters
The compact coreless sensor compensates for powertrain vibrations to maintain current measurement accuracy.
The short version
- Texas Instruments announced the TMCS2100-Q1 sensor, designed to measure electrical current in EV traction inverters by tracking magnetic fields horizontally and vertically.
- The dual-direction approach aims to compensate for motor vibrations, which can distort current readings in existing coreless sensors.
- TI states the component could lead to smoother acceleration, quieter operation, and minor gains in EV efficiency.
- The extent of real-world efficiency gains will depend on how automakers integrate the sensor into their powertrain designs.
Key facts
- Texas Instruments unveiled the TMCS2100-Q1 sensor, a coreless component designed for electric vehicle traction inverters.[Electrek]
- The sensor measures magnetic fields horizontally and vertically simultaneously to counteract physical position shifts caused by vehicle vibration.[Electrek]
- Texas Instruments claims the sensor limits measurement error to under 1% during a 0.4 mm shift, making it up to 20 times more accurate than single-direction coreless sensors.[Electrek]
- The small footprint of coreless sensors allows vehicle manufacturers to build lighter and smaller traction inverters.[Electrek]
What remains uncertain
- The precise impact on EV driving range and motor noise remains unknown as performance will depend on specific automaker implementations.[Electrek]
