Ionna is a DC fast-charging network launched jointly by a coalition of major automakers, built specifically to expand reliable high-power charging infrastructure in North America.
Why automakers built their own network
Rather than relying solely on existing third-party networks, several automakers pooled resources to build Ionna with an explicit focus on high uptime, high-power stalls, and convenient highway-corridor and urban locations.
Open to any compatible vehicle
Despite being automaker-backed, Ionna stations are designed to serve any EV with a compatible connector, not just vehicles from the founding brands — similar in spirit to how most modern networks operate.
What to expect
As a newer network, Ionna's station count is still growing compared to established players like Electrify America or ChargePoint, but its stations tend to offer modern, high-power hardware from the start.
