Hall effect sensors
The Hall effect has been the mainstay of magnetic sensing since it was discovered by US physicist Edwin Hall in 1879. The effect describes the creation of an electric field in a conductor that carries a current and is placed perpendicular to a magnetic field. The fact that the induced voltage is proportional to the magnetic field provides a measurement that is used to control brushless motors and the position of almost anything that rotates. More…

DAFO Vehicle battery fire protection system
In a thermal runaway, a lithium-ion battery typically releases oxygen from the cathode and volatile hydrocarbons from the electrolyte, generating both oxidiser and fuel to sustain a fire from purely internal sources (writes Peter Donaldson). Reliable detection and early intervention are therefore critical for preventing the worst consequences of battery thermal incidents – fire and […] More…
Self-developments
Developers of charging systems are looking to address key challenges for fast charging and higher capacity battery packs, and this is leading to automated charging systems. More…

System-level approach to NVH models
Complex interactions between electric powertrain components provide significant challenges in accurately predicting the noise, vibration and harshness (NVH) performance of a design when using high level system-level models (writes Nick Flaherty). The models can help reduce the cost and development time, but the underlying interaction of the component-level simulations needs to be understood to achieve […] More…

Ensuring the cleanliness of battery modules
Industrial image processing specialist Vitronic is testing a new inline inspection method that can detect particle contamination during the assembly of battery modules. The contaminants can impair battery performance, and are also suspected of causing them to catch fire. The system could be used in the gigafactories being planned or under construction across Europe. Since […] More…
HVAC Systems
While most drivers of IC-engined vehicles are vaguely aware that running the air conditioning increases fuel consumption, such is the energy density of petrol and diesel that it has rarely been a major concern, although with fuel prices at record highs that is changing rapidly. Similarly, IC engines produce so much waste heat that drawing upon it to warm up the cabin on a cold day has a negligible effect on fuel burn. More…
Super-fast silicon cell charging
BATTERY CHARGING Enovix has demonstrated 5 minute charging of its prototype silicon battery cells for EVs (writes Nick Flaherty). Tests on the 0.27 Ah cells demonstrate charging from 0 to 80% charge in 5.2 minutes, and achieve a greater than 98% charge capacity in under 10 minutes. The cell uses a 100% silicon anode with […] More…
