Engineering specialist IAV and semiconductor agency Nexperia have developed a lab-validated idea referred to as ONE Inverter that makes use of software-defined management and bidirectional GaN switching to handle particular person battery sections moderately than treating a pack as a single unit.
In typical series-string battery architectures, each cell should carry the identical present, that means the pack’s efficient capability is constrained by its weakest cell. ONE Inverter addresses this by dynamically allocating and controlling battery sections via a software program layer, permitting every part to contribute in keeping with its precise state moderately than being dragged down by degraded neighbors. The identical structure additionally permits capabilities that presently require separate energy electronics techniques to be mixed right into a single system idea.
The technical enabler is Nexperia’s bidirectional GaN system, which permits quick, environment friendly switching on the battery part stage. IAV says different semiconductor applied sciences would improve system complexity and value to the purpose of constructing the method unviable—GaN’s low switching losses and compact die measurement are what make per-section management economically workable. Bipolar gadgets from Nexperia’s broader portfolio additionally help the general design. IAV developed the software-defined system structure and battery management technique.
“By combining IAV’s experience in battery techniques, software program and car architectures with Nexperia’s semiconductor and packaging know-how, we’re exploring new methods to assist prospects construct extra environment friendly, resilient and future-ready electrical mobility options,” stated Jörg Astalosch, CEO of IAV.
