To continuously and accurately monitor the internal status of EV batteries, LEM introduced its new class of Hall-based, open-loop current sensors called the single monitoring unit (SMU).

If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the advent of the Hall-effect sensor has provided us ...

Explore the latest breakthroughs in sensor technology driving efficiency and performance in EVs and renewable energy.

Current sensors measure AC and/or DC current levels. The sensors in this selection guide measure current and provide some sort of output that corresponds to the current being measured. The most ...

More and more keyboards and video game controllers employ Hall effect sensors, but what exactly is this technology? We break ...

Learn more about the single monitoring unit (SMU) from LEM and how it could facilitate ... validation of battery-management systems using sensor simulation on a modular and scalable platform ...

Shares in LEM Holding plummeted on Monday after the Swiss electronics manufacturer delayed its sales target amid a slowdown in demand and no signs of recovery for the remainder of the year. In ...

In Germany, it was natural that manufacturers developing metering products for the EV charging market turned to the non-profit VDE Institute to provide a measurement set-up for calibration that ...

The sensors use the Hall effect, an electrical potential (the Hall voltage) that is developed between the two edges of a current-carrying conductor whose faces are perpendicular to an applied current ...

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and ...

The orchestrator of it all was a communist committee, acting under the name... Stanisław Lem. Philip K Dick, photo: Leemage / East News The unveiler of such an insidious subterfuge was none other than ...

Researchers led by Prof. Cunlan Guo at Wuhan University have pioneered a new approach to control the electrical properties of ...
