BYD registers ‘Ao Guang’ trademark covering solar cells and batteries

The significance lies less in the name than in the breadth: a single filing spanning storage batteries, EV charging infrastructure and photovoltaic cells signals that BYD is positioning across the full energy chain rather than vehicles alone. That puts it in closer conceptual overlap with integrated solar-and-storage players, though a trademark registration is a claim on a name, not evidence of product intent. Whether the filing is defensive housekeeping or a precursor to a consumer-facing energy brand is the open question worth watching.
