Littelfuse Launches Residual Current Monitors for EV Charging
Stations
Vacuumschmelze is also a developer of magnetic materials for sensing.
Its nickel-iron materials, for example, exhibit high permeabilities
which match well with demanding applications where the highest
accuracy in magnetic sensing is necessary. Low coercivity NiFe alloys
with a nickel content of 69-82% are a frequent choice for these applications.
TDK
magnetic current sensors for EV charging
In October, Littelfuse introduced the RCMP20 Residual Current
Monitor Series for Mode 2 and Mode 3 EV charging stations. The
monitors set a new standard in charging safety, offering superior
performance and flexibility in a compact design while supporting
higher charging currents than other solutions on the market, says
the company. Their large current transformer aperture expands the
Littelfuse EV infrastructure portfolio and enhances electrical safety
in EV charging applications.
Vacuumschmelze current sensors and alloys
TDK's CUR 4000 is a single-axis contactless magnetic-field sensor for
galvanically isolated DC and AC current measurements - a flexible
multi-Hall array sensor for high-precision current sensing.
Inside the VAC 4641-X900 differential current sensor
In a specialized approach from Vacuumschmelze, integrating a
VAC differential current sensor into an IC-CPD or wall box provides
the EV charging electronics with all-current sensitivity and electrical
safety at a low cost. If the sensor detects a fault current, the corresponding
output will change its state.
Design variants with integrated primary conductors for one- or threephase
systems are available, together with a pass-through variant.

TDK, a prolific developer of magnetic sensing products, recently
came out with the CUR 4000 sensor for current measurements in
automotive and industrial applications such as high-voltage battery
monitoring systems of hybrid and electric vehicles. A flexible
multi-Hall array allows linear or differential magnetic-field sensing
for contactless and precise current sensing up to ≥2000 A. It can be
used for different module concepts like core-based or coreless. In
linear modes, a configurable array of Hall elements enables highly
accurate measurements for core-based stray-field robust sensormodule
designs. The differential mode enables small coreless and
stray-field robust system designs without shields.
