We address the issues in batteries with the safest, elegant and inexpensive
way Our solution lays in MicroWire – a sensor of physical quantities like
temperature, vibration, position, electric current, magnetic field, etc.
The MicroWire is a miniaturized sensor, thin like human hair, it is resistant
to chemically aggressive environments, thus can be embedded directly into the
batteries’(even considering the internal hazardous, acidic environments), and
provide contactless and spark-less sensing (this prevents any ignition
possibilities). It has an operating temperature range of –273 to 600°C and a
sensing frequency of up to 10.000 times per second. Ultimately we have a sensor
and sensing system that provides accurate non-destructive testing and
measurements from within the battery, without any contact or wiring, with no
influence from an aggressive chemical environment, thus enabling predictive
maintenance for the whole battery unit in the safest way possible.
RVmagnetics sensing solution offers:
allowing thermal management from within the battery
battery thermal runaway prevention
detecting energy waste through pressure and vibration monitoring
MicroWire not effected by battery acidic environments
no ignition/spark risks (wireless)
in combination with the control unit preventing battery capacity waste
increased battery safety
and reducing waste at battery manufacturing level
non-destructive testing of welding cracks, deformations, caging damages
preventive maintenance to control thermal issues
predictive maintenance: real-time monitoring possibility during the lifetime
of the battery
1. Contactless sensing
Allows contactless sensing due to magnetic nature.
Lifespan of the sensor itself is longer than 1000+ yrs.
3. Low power consumption (Sensing system/device)
Sensing system/device is powered in Microampere (µA).
4. Magnetic bi-stability
Sensors are always in saturation. Heavy magnetic and heavy electric fields do not influence the measurement.
