n LEM is a specialist and market leader in the production of isolated current and voltage transducers. From its beginnings in a Geneva, Switzerland kitchen in 1972, LEM has evolved over 40 years into an international company of more than 1200 people with manufacturing operations in Geneva, Tokyo and Beijing, and with a sales support network spanning the globe. Over 2000 references fill LEM’s catalog serving multiple markets.
LEM designs, develops and manufactures technology that is used in solar panels and windmills, industrial robots and household washing machines, hospital and data center backup-power applications, train locomotives and automobiles. Over 6% of the company’s revenues are reinvested in research and development, allowing LEM to offer innovative products of the highest quality manufactured with state-of-the-art methods. In the automotive market, LEM works with all the major car manufacturers and Tier-1 suppliers in the world, and supplies galvanically-isolated electronic transducers that measure electrical parameters in battery-management and motor-control applications.
The ever more stringent requirements for energy efficiency and reduced CO2 emissions lead car manufacturers to increasingly depend on on-board electrical components. From electric power-steering and stop-start technologies to on-board navigation and infotainment systems, these components put an additional load on the electrical circuits and particularly the battery, making it essential to control the energy generated and consumed by the various on-board systems. In collaboration with its customers and with the help of powerful simulation techniques, LEM uses the most-appropriate technology (from Hall-cell to fluxgate) to address the specific need of measuring the currents (coulombs) entering and leaving the car’s battery and/or the alternator. This allows an intelligent management of available power that leads to the increased efficiency of today’s internal-combustion engines. More importantly still, the hybrid- and electric-vehicles entering the market today depend on accurate measurement of battery-pack currents to determine the available driving range and recharging strategy. LEM has the technology.
Not only must battery currents be accurately measured in hybrid- and electric-vehicles, but the electric motors driving the wheels of this new generation of automobiles also need to be precisely controlled to allow smooth operation. Electric motor phase-current sensing has been LEM’s core competency since its beginning and remains today a major application for its technology. LEM has a dedicated product range for measuring phase-currents in motors and DC-DC converters essential to all hybrid- and electric-vehicles.
LEM is a key player in the new generation of automobiles, using its know-how acquired over 40 years to develop the specific technologies to measure battery and motor-phase currents that allow the car industry to meet the ever increasing requirements in energy efficiency. The following pages give you an introduction into LEM’s technology for automotive applications.

The magnetic flux created by the primary current IP is concentrated in a magnetic circuit and measured in the air gap using a Hall device. The output from the Hall device is then conditioned to provide an exact representa-tion of the primary current.
Advantages:
- Full galvanic isolation- No insertion losses- Small package size- Extended measuring range- Reduced weight- Low power consumption
- Programmable low-pass filter- Digital signal processing- Low offset error- Bus-bar or wiring-harness mounting

- Water-resistant designs- Protected against over-voltage and reverse-polarity- Ideal for battery monitoring applications
- Very low offset & gain error- Excellent accuracy- High sensitivity- Excellent linearity- Wide dynamic measurement range (from 1mA to 1000A)
A magnetic core is saturated in alternating directions by a powered secondary winding. The magnetic flux generated by a primary current going through this core will modify its saturation curve.The integration of this saturation curve over time gives an exact image of the primary current, with zero offset.
- High frequency bandwidth- Fast response time- Bus-bar and PCB-mounting designs
- Support high-amplitude, high-frequency currents- Ideal for motor control, and DC-DC converter applications
