The rapid growth of electric vehicles (EVs) is reshaping transportation, but the real driver accelerating this paradigm shift is the accelerated buildout of EV charging infrastructure. The hardware, software, and systems that make up EV charging infrastructure play a critical role in enabling sustainable mobility and achieving net-zero goals. In this article, we’ll discuss what EV charging infrastructure is, the current state of EV charging infrastructure, and the challenges and opportunities provided by the electrification of transportation.
What is EV Charging Infrastructure?
EV charging infrastructure includes the components, systems, and facilities that support EV charging:
- Charging stations are dedicated facilities containing one or more EV charging ports
- EV charging ports provide four levels (or rates) of charging:
- Level 1 charging plugs directly into a standard 110-volt outlet and delivers the slowest charge at approximately five miles of range per hour of charging
- Level 2 charging delivers significantly improved charging times of approximately 25 miles of range per hour of charge. Nearly three-quarters of public EV charging ports in the United States are Level 2
- Level 3 charging, also called direct-current fast charging (DCFC) delivers 100 to 200+ miles of range in half an hour of charging
- Level 4 charging: This type of ultra-fast charging is usually reserved for dealerships and OEM use
- EV charger connectors (also known as “plugs”) are the interface connecting EVs to a charging source. There are four plug connector types commonly used in the U.S.:
- Type 1 SAE J1772 (or “J-plug”) facilitates Levels 1 and 2 charging for all vehicles sold in the United States and Japan
- Combined Charging System (CCS) facilitates fast Level 3 charging for most non-Tesla vehicles. CCS plugs combine a J1772 AC connector with two additional DC conductors
- CHAdeMO is a ten-pin Level 3 plug most commonly used for charging certain Japanese EV models
- North American Charging Standard (NACS) is a compact SAE J3400 plug providing both AC and DC fast charging. NACS is being adopted by automakers such as Ford, General Motors, Rivian, Volvo, Mercedes-Benz, Polestar, and Nissan
- Software platforms for EV charging and energy management. EV charging software enables CPOs and e-mobility service providers to manage all aspects of EV charging, maximizing charger uptime and providing drivers with an exceptional EV charging experience. EV charging software offers an end-to-end solution for charging networks, including:
- EV charging operations
- EV charging billing
- Energy management
- EV driver management
- EV Fleet management
- Integration and interoperability
- Grid integration and smart energy management. Three-quarters of electric vehicle charging station developers and operators say grid limitations present a significant barrier to deploying commercial EV charging infrastructure. Smart energy management helps optimize EV charging assets by increasing charging capacity up to 6x without upgrading a single piece of infrastructure.
The Current State of EV Charging Infrastructure
China, Europe, and the United States are the primary EV infrastructure markets. As of January, there are ~230,000 public charging ports in the U.S. with an additional 1,000 being installed each week. Europe surpassed 900,000 charging ports in 2024. China is the uncontested leader in EV infrastructure buildout, boasting over 3.2 million charging ports in 2024, over half of which are fast DC chargers.
Challenges facing EV infrastructure buildout
- Currently, EV charge ports are less reliable than gas pumps, resulting in “charge anxiety” for EV drivers.
- If EV adoption is to meet or exceed that of ICE vehicles, charging network reliability needs to be on par with traditional fueling stations. However, reaching an economy of scale analogous to liquid fueling stations is a major hurdle the sector needs to overcome quickly and efficiently.
- Load demand. Multiple EVs charging simultaneously can significantly strain local power grids, potentially causing power outages, voltage fluctuations, and grid instability, particularly during peak hours. CPOs must accurately predict the demand for their assets on a tenuous grid and reward drivers who are willing to charge outside of peak hours through Demand Response. This avoids outages and saves money for charging customers.
- Equity and charger access. Public charging isn’t readily available for 40 percent of Americans. Most charging stations are located in concentrated urban areas, underscoring the urgent need for infrastructure serving rural and marginalized citizens.
Building the Future of EV Charging Infrastructure (2025 and Beyond)
Scaling up
“On the go” and destination charging are essential to accelerating EV adoption, and charge-ups need to be as simple and convenient as refueling an internal combustion engine (ICE) vehicle at a gas station. Existing liquid fuel networks represent a balanced equation of low costs, efficiency, convenience, and capacity utilization, creating a convenient travel modality that motorists have come to expect. This model offers a compelling blueprint for EV charging infrastructure to emulate and iterate upon. Major American federal investments in EV infrastructure such as the National Electric Vehicle Infrastructure Formula Program (NEVI) and the Alternative Fuel Corridors grant program are slated to drastically accelerate buildout in 2025 using highway corridor stations as a blueprint.
Technological Advancements
Sector-coupling technologies such as Vehicle-to-grid (V2G) and bidirectional charging reduce energy price volatility and integrate renewable energy by utilizing EV batteries as Distributed Energy Resources (DERs).
AI-enabled grid balancing identifies ideal charging times and locations depending on grid conditions, charging patterns and charging equipment status. By leveraging time-of-use (ToU) rates, optimized charging schedules can reduce costs and improve utilization rates, allowing for consistent day-ahead or intra-trip charging planning. CPOs must increasingly leverage AI to optimize charging load across multiple stations to mitigate grid overload, reduce charger downtime, and increase customer throughput.
Smart energy management systems identify complex patterns impacting load demand, enabling pin-point forecasts and optimal grid integration for intermittent renewable energy resources. As weather and load demand become more unpredictable, AI-enabled smart energy management systems can automatically meet real-world conditions, providing the stability necessary for sector-wide buy-in and consumer adoption.
Using EV batteries as distributed energy resources (DER) helps drive a more sustainable, stable grid, enabling CPOs to dynamically deploy energy storage assets in response to real-time renewable energy generation, weather conditions, charge load demand, and more. Smart grid technologies, like Vehicle-to-Grid (V2G), enhance the integration of renewable energy by dynamically adjusting to fluctuations in electricity demand. They prioritize charging electric vehicles (EVs) with the lowest battery levels and allow fully charged EVs that aren’t in use to send energy back to the grid, optimizing both energy storage and grid stability.
The Importance of a Robust EV Charging Infrastructure Ecosystem
Public and Private Collaboration
EV charging infrastructure companies are poised to innovate upon the existing ICE automotive experience. CPOs have a unique opportunity to work with utilities, governments, and private companies to accelerate EV infrastructure buildout, creating a robust EV charging ecosystem analogous to traditional fueling stations. For example, private EV fleet charging infrastructure buildout helps lay the groundwork for additional public EV charging infrastructure developments.
Interoperability and Roaming
Seamless user experience with EV charging infrastructure ensures a smooth transition from ICE vehicles to EVs. Analogous to traditional fueling, EV drivers need reliable ways to interact seamlessly with various charging networks. EV charging roaming, or eRoaming, allows drivers to charge their vehicles at any participating charging station. This is possible through commercial agreements between EV charging providers . Selecting network- and equipment-agnostic software solutions future-proofs infrastructure investments, enabling CPOs to make the most of existing resources and ensuring a seamless charging experience across networks to help make scalability a reality.
User Experience
In our experience, 80 percent of charger-related issues can be fixed remotely, saving drivers time while reducing costly site visits and maximizing customer throughput. EV charging and energy management software systems facilitate highly personalized experiences, ultimately leading to greater customer satisfaction and loyalty. System-level visibility and a focus on customer experience are winning recipes for CPOs.
