Charging network

On this page 7

A charging network is a set of electric vehicle charging stations operated or marketed under one organization, with common access methods, pricing, software management and customer support. In charging infrastructure, the term covers both the physical chargers spread across locations and the back-end platform that monitors them, authorizes sessions and handles billing.

For drivers of electric vehicles, the charging network is what turns individual chargers into a usable service: it decides how a session is started, what it costs, whether chargers show live availability and how failures are handled. For operators, it is a business that must balance site costs, grid connections, utilization and reliability.

How a charging network is organized

A charging network combines hardware in the field with software in the cloud. Each charger, technically an EVSE (electric vehicle supply equipment), connects to a central management system, typically using the Open Charge Point Protocol (OCPP), which reports status, receives commands and records energy delivered.

Several commercial roles are involved, and one company may hold more than one of them. The charge point operator (CPO) runs the chargers, while the e-mobility service provider (eMSP) holds the customer relationship through an app or card. Roaming platforms connect them so that a driver of one provider can charge on another network.

Types of charging networks

Charging networks differ mainly in charging power, location type and target users. A single network may combine several types, but most are optimized around one dominant use case.

Network typeTypical power per pointTypical use
Destination AC networkAbout 7-22 kWHotels, shops, workplaces, longer stays
Urban fast-charging networkAbout 50-150 kWCity drivers without home charging
Highway high-power networkAbout 150-400 kWLong-distance travel, short stops
Manufacturer networkVaries, often high powerInitially brand owners, increasingly open to all
Fleet and depot networkAC to high-power DCBuses, delivery vans, taxis
Heavy-duty networkUp to megawatt levelTrucks using megawatt charging
Common types of charging networks

High-power networks increasingly build charging hubs with many points per site. Larger sites improve the chance that a charger is free, spread fixed costs such as the grid connection, and make it easier to offer amenities that suit 20-40 minute stops.

Access, payment and roaming

How a driver starts and pays for a session is one of the most visible differences between networks. Historically, many networks required their own app or card, which fragmented the experience.

Access methodHow it worksMain advantage
Network app or cardDriver registers with the operatorMember pricing and full features
Roaming via a third-party providereMSP contract works on many networksOne account for many networks
Ad hoc paymentContactless card or QR code at the chargerNo registration needed
Plug and ChargeVehicle authenticates itself via ISO 15118Session starts automatically on plug-in
Ways to access a charging network

In the European Union, the Alternative Fuels Infrastructure Regulation (AFIR) requires ad hoc payment at new public chargers and contactless card payment at higher-power chargers along major roads, together with transparent pricing. Roaming prices can still differ from direct prices, so drivers on frequent routes often compare tariffs.

What makes a charging network reliable

For drivers, reliability matters more than the number of chargers. A network with many sites but frequent faults creates more frustration than a smaller network with dependable equipment.

Operators track charger uptime, the share of time a charger is able to deliver energy. Uptime figures can be misleading, because a charger may report itself as available while a payment terminal, cable or communication link has failed. Session success rate, the share of attempted sessions that actually deliver energy, is often a better indicator of real reliability.

  • Remote monitoring through OCPP to detect faults and reboot chargers.
  • Spare parts and service contracts with defined response times.
  • Robust cables and connectors, a frequent point of physical failure.
  • Accurate live status data shared with apps and route planners.
  • Dynamic load management so that several cars can charge on a limited grid connection.

Physical design also affects reliability. Pull-through bays suit vans and cars with trailers, cable length must reach charging ports on either side of the vehicle, and lighting and canopies make stops safer at night and in bad weather. These details rarely appear in network statistics but strongly influence whether drivers trust a network.

Challenges and common misconceptions

Charging networks face structural economic challenges that are not obvious to drivers. The table below summarizes the main ones.

Key challenges for charging networks

A common misconception is that more networks automatically mean better coverage. Without roaming and open payment, many separate networks can make charging harder to use, which is why regulation and industry protocols such as OCPI focus on interoperability.

The simple explanation

A charging network is like a chain of fuel stations, but for electric cars. One company runs many charging points in different places. They work the same way, use the same app and follow the same prices.

Drivers do not always need to sign up with each network. Many chargers accept a bank card. Some apps also work on many networks at once. What drivers value most is that the charger works when they arrive.

How it is used in practice

A salesperson covers a region of about 300 km in an electric car and charges mostly on the road. He uses one roaming app that works across several networks, but he also holds a subscription with the highway network he uses most, which lowers his price per kWh.

Before each trip, his route planner checks live status and picks a charging hub with eight high-power points rather than a single charger at a remote petrol station. When one charger fails to start a session, he moves to the next bay, and the operator’s remote monitoring has already flagged the fault. Over a month, the combination of subscription and dependable hubs cuts both his charging costs and his waiting time.
