To enable system engineers in the EV industry to take the next step towards transformer-less on-board chargers (OBCs), LEM has designed the first automotive grade residual current monitoring (RCM) type B sensor for bi-directional OBCs with ASIL B capabilities.

LEM has announced the launch of its latest innovation: the Single Monitoring Unit (SMU) sensor family.

To meet the rising global demand for current and voltage sensing, driven by the global shift toward decarbonisation and electrification, LEM, a leader in electrical measurement technology, has opened new research and development centres in Munich, Germany, and Shanghai, China. These facilities are key to LEM’s strategy of integrating greater intelligence into its sensors while ensuring closer proximity to key customers, promoting deeper col...

LEM has inaugurated a new €15.7mn factory in Malaysia that combines environment-friendly design with advanced manufacturing technology.

 LEM has recently introduced an addition to its CDSR series of Residual Current Monitors, enhancing safety and reliability for AC wall boxes and charging cables. The latest model in the series now comes with three output options - fault output, SPI bus, and analogue output.

LEM has launched a new product in its CDSR series of Residual Current Monitors.

LEM has launched the HAH3DR S07/SP42, a new compact current sensor designed for 800V three-phase power modules.

Mathieu Beguin, Global Product Manager at LEM discusses the opportunities fast charging brings. 

LEM will use PCIM 2023 to give the global e-mobility market advance notice of its new DC energy meter for DC wallbox chargers of EVs.

As a result of intensive work with organisations that oversee certification across the whole of France, the DCBM 400/600 DC billing meter for high-power EV charging has been approved by LNE in terms of the unit’s design and quality compliance for this key market.

Electrical measurement technology specialist LEM will use PCIM 2023 to give the global e-mobility market advance notice of its new DC energy meter for DC wallbox chargers of electric vehicles (EVs).

On-board train metering is essential if rail companies are to ensure they have an accurate record of their energy usage. By Florent Balboni, Global Product Manager, LEM for energy metering.

One of the biggest issues in the EV sector is the need to develop vehicles that can travel the furthest possible distances between charges and so design engineers are continually searching for sensors that can offer the superior levels of efficiency and accuracy they require.

Distance and speed of charging are vital in the competitive EV sector and, like all vehicle components, high-power integrated traction inverters – which convert DC into AC and capture energy for the vehicle – need to combine superior performance with being as small and light as possible. 

Electrical measurement technology company LEM believes its UL-certified Direct Current Billing Meter (DCBM) will help accelerate the development of an extensive charging infrastructure across North America.
