Manufacturer's Description

Bringing the magnetic field measurement resolution towards that of more complex magnetic sensors, yet with the small size and ease of use of a Hall sensor, the GHS01AT can address monitoring tasks which conventional technologies simply cannot provide an effective solution for.

The new GHS01AT Hall Effect sensors are ideally suited to the battery market. Here they will be of great value in battery cell analysis when investigating the validity of different battery cell chemistry derivatives and form factors under development. Using these magnetic sensors, it will be possible to get a more detailed and localised (point-to-point) understanding of battery cell behaviour.

By utilising a graphene monolayer (just 0.34nm thick) the GHS01AT is not affected by the presence of in-plane stray electromagnetic fields that would severely impact on the accuracy of alternative sensing mechanisms. The small footprint allows good spatial resolution.

The method is an indirect means for measuring real-time magnetic field (produced by current flowing through the cell) data, so one of the advantages is that the battery cell itself and the tabs/busbars feeding into the cells are not disrupted during testing.

The method is technology agnostic – use for liquid electrolyte or solid state batteries, different chemistries, pouch and cylindrical cells.

These measurements can be facilitated by the GHS Array Starter Kit.

The standard GHS01AT Kit includes a GHS01AT sensor and a small interface PCB for ease and convenience of implementation.
