Innovation isn't a marketing word at DHES — it's certified. The China National Intellectual Property Administration (CNIPA) has granted Liaoning Dahua Energy seven utility-model patents, covering key technologies across our charging portfolio.

What the patents cover

The seven patents span real, practical inventions, including:

  • An intelligent cabinet-type energy-storage station for charging piles
  • An intelligent flexible charging-pile device
  • A split-type DC charger
  • An anti-collision charging pile
  • An outdoor self-service EV charging pile
  • A distributed battery-swap and energy-storage charging pile
  • An outdoor charging pile with a protective structure

Why it matters for buyers

Patents signal genuine in-house R&D and engineering depth — not rebadged hardware. For buyers, that translates into better-designed products, meaningful differentiation and a partner investing in the future of charging.

You can view all seven certificates in the Certifications section on our About page.

Protected innovation is how we keep our promise to power every charge and empower every future.
