Description
Jicheng Yu and four colleagues design a 2026 sensor array for measuring current in electric vehicle charging cables without touching them. Accurate cable current readings govern charging station safety and performance, since insulation faults can cause shocks or fires. Their array uses tunnel magnetoresistance sensors, which sense magnetic fields from the cable's current.
Bench tests showed the array beat a single sensor, with best accuracy at a 3 centimeter distance from the cable. The setup then tracked real-time charging current across ten different vehicle brands and models. Yu and co-authors present the array as a precise, stable, non-contact monitor suited to the fast-growing charging networks that new energy vehicles depend on.
