A New Partnership Focused on Infrastructure Growth

A major collaboration between Circle K and Ionna aims to significantly expand public fast-charging access across the United States. The two companies confirmed plans to install high-speed charging stations at hundreds of retail locations, marking another step in the ongoing effort to strengthen EV infrastructure nationwide.

Ionna Charging Station


Scaling Up a Rapidly Growing Network

Ionna, a charging venture backed by eight major automakers, including General Motors, Stellantis, and Toyota, has been accelerating its rollout of so-called “Rechargeries.” Under the new agreement, the company intends to deploy its charging technology at more than 350 Circle K sites across the country.

Each location will feature high-output charging equipment rated at up to 400 kilowatts, compatible with both CCS and NACS connectors. This dual-standard approach is designed to accommodate a broad range of electric vehicles, reducing compatibility concerns for drivers.

The partnership aligns with Ionna’s long-term objective of building 30,000 charging bays by 2030, positioning it as a major player in the evolving U.S. charging landscape.


Integration of Existing Charging Assets

Beyond new installations, the agreement also includes the transfer of Circle K’s current EV charging infrastructure into Ionna’s network. According to federal data, the retailer already operates 378 charging ports across 93 locations.

Ionna plans to upgrade approximately 85 of these existing sites, enhancing both performance and usability. This process will likely involve hardware improvements and software integration, ensuring a more consistent experience across the network.

By absorbing these assets, Ionna can expand its footprint more quickly than through new construction alone, while modernizing older installations that may not meet current performance expectations.


Retail Locations as Charging Hubs

The collaboration reflects a broader industry trend: integrating EV charging into familiar roadside destinations. Convenience stores and fuel stations are increasingly seen as ideal locations for fast chargers due to their accessibility and existing amenities.

For drivers, these sites offer practical benefits such as restrooms, food options, and seating areas, making longer charging sessions more manageable. Unlike traditional refueling, EV charging often requires 20 to 30 minutes, creating demand for comfortable waiting environments.

Ionna’s approach builds on this concept by designing charging sites that resemble upgraded rest stops, sometimes including enhanced facilities beyond basic retail offerings.


Competitive Momentum Across the Industry

This partnership is part of a wider wave of collaborations between charging providers and retail chains. Over the past year, Ionna has also worked with brands like Sheetz and Wawa to expand its network.

Other automakers and infrastructure companies are pursuing similar strategies. For example, General Motors and EVgo have been deploying chargers at Pilot and Flying J travel centers, while Mercedes-Benz High Power Charging is partnering with Buc-ee’s to bring fast charging to its large-format roadside locations.

These initiatives highlight a shared industry belief that charging accessibility and convenience are critical to supporting future EV adoption.


Addressing Key Barriers to EV Adoption

Reliable public charging remains one of the most cited concerns among potential EV buyers. Although overall EV sales growth has slowed following policy changes—such as the expiration of certain federal incentives—the build-out of fast-charging infrastructure has continued at a strong pace.

By placing chargers at widely recognized retail destinations, companies hope to reduce range anxiety and make EV ownership more practical for drivers without home charging options.

At the same time, retailers benefit from increased customer dwell time. While traditional fuel stops are brief, EV charging sessions encourage drivers to spend more time—and potentially more money—on-site.

Looking Ahead

The partnership between Ionna and Circle K illustrates how infrastructure development is evolving beyond standalone charging stations toward integrated, service-oriented locations. As networks expand and technology improves, the focus is shifting toward speed, convenience, and user experience.

If execution matches ambition, this rollout could play a meaningful role in closing infrastructure gaps and supporting the next phase of electric vehicle adoption in the United States.

FAQs - Level 3 DC Fast Charging

What is Level 3 DC fast charging for electric vehicles?

Level 3 charging, also known as DC fast charging (DCFC), provides direct current at high power levels (typically 50 kW to 350 kW) to quickly recharge an electric vehicle battery. Unlike Level 1 and Level 2 charging, DC fast charging bypasses the onboard charger, enabling much faster energy transfer.

How fast is Level 3 DC fast charging compared to Level 2 charging?

Level 2 chargers (240V AC) usually add 20–30 miles of range per hour, while Level 3 DC fast chargers can add 100–300 miles of range in 20–40 minutes, depending on EV battery capacity and charging power.

Does Level 3 fast charging damage EV batteries?

Frequent use of DC fast charging can accelerate battery degradation over time due to higher heat generation and faster charge cycles. However, modern EVs have battery thermal management systems that minimize impact. Occasional fast charging is safe and convenient for road trips.

What connector types are used for Level 3 DC fast charging?

The main EV fast charging connectors in North America are:

  • CCS (Combined Charging System) – widely adopted by most automakers
  • CHAdeMO – mainly used by older Nissan LEAF models
  • NACS (Tesla plug) – now being adopted across multiple brands (Ford, GM, Rivian, etc.)
What is the maximum power output of Level 3 DC fast charging stations?

Most public DC fast chargers range from 50 kW to 150 kW, while ultra-fast chargers can reach 250 kW to 350 kW. Tesla Superchargers V3 deliver up to 250 kW, and upcoming next-gen chargers may exceed 500 kW for heavy-duty EVs.

How much does Level 3 DC fast charging cost?

Pricing varies by network and location. Costs are usually based on per kWh, per minute, or a flat session fee. In the U.S., rates typically range from $0.25 to $0.60 per kWh, which is higher than home charging but competitive compared to gasoline costs.

Where can I find Level 3 DC fast charging stations in the U.S.?

DC fast chargers are commonly located along highways, rest stops, shopping centers, and EV charging networks like Tesla Supercharger, Electrify America, EVgo, and ChargePoint. Apps like PlugShare and ChargeHub help drivers locate fast charging stations.

Can all EVs use Level 3 DC fast charging?

Not all EVs are compatible. Some plug-in hybrid EVs (PHEVs) and older models lack DC fast charging capability. The maximum charging speed also depends on the vehicle’s onboard DC charging acceptance rate, which can range from 50 kW to 270 kW.

How does weather affect Level 3 DC charging speed?

Extreme cold or heat impacts battery temperature management, reducing fast charging speeds. EVs often precondition the battery before arriving at a fast charger to optimize charging efficiency in winter or summer conditions.

What is the future of Level 3 DC fast charging technology?

The future includes ultra-fast chargers (500 kW+), widespread adoption of NACS connectors, and vehicle-to-grid (V2G) integration. As EV infrastructure expands, Level 3 charging will become even more essential for long-distance travel and heavy-duty electric trucks.
