Charged EVs | Heliox pilots its new Flex Pro 480 kW DC fast EV charger with King County Metro

Heliox, a Siemens business, has partnered with transit agency King County Metro to conduct a pilot of the company’s new Flex Pro DC fast EV charger.

King County Metro provides bus, trolley, on-demand, paratransit, vanpool and water taxi services in the Seattle metro area.

The Heliox Flex Pro delivers up to 480 kW of power in a compact footprint (12 sq ft) that’s suitable for high-density transit depots. The system supports CCS1 charging at 250 A, and inverted pantograph chargers in 250 A or 600 A configurations. This offers the flexibility to support high-power pantograph charging for rapid turnaround or to connect with up to six depot pantographs and plug-in dispensers for off-shift charging.

Flex Pro can distribute power in 80 kW increments across up to six outlets and serve up to six vehicles at the same time. Customers can choose dynamic or static power sharing to match site needs and operating priorities: dynamic power sharing continuously optimizes available power across charging points, while static power sharing provides predictable output and greater control.

Flex Pro is backward-compatible with existing Flex dispensers and includes built‑in support for future expansion. A modular power architecture allows charging sessions to continue at slightly reduced output if a power module or group fails.

Flex Pro includes a 24‑month warranty, offers preventative maintenance, and is available in both Build America, Buy America compliant (BABA) and non‑compliant versions.
