EV Charging Infrastructure Software in 2026: The Backend Reality
EV charging infrastructure has matured. The software that makes it work — and where the operational complexity lives.
EV charging infrastructure has matured significantly through 2020-2026. The software that operates this infrastructure — Charging Station Management Systems (CSMS), payment platforms, network operations, plus the increasing AI/ML integration — has become a substantial software category in its own right.
I want to walk through where EV charging infrastructure software actually sits in 2026.
The actor types#
The EV charging ecosystem has specific actor types:
CPO (Charge Point Operator) — owns and operates physical charging stations.
EMP / MSP (Mobility Service Provider) — provides services to EV drivers (apps, billing).
eMSP (e-Mobility Service Provider) — sometimes distinct from CPO.
Roaming operators — enable cross-network charging.
OEMs — vehicle manufacturers, often with their own charging brand.
Utilities — increasingly significant as grid integration matters.
The protocols#
The protocol layer:
OCPP (Open Charge Point Protocol) — communication between charging station and CSMS. OCPP 1.6 widespread; OCPP 2.0.1 increasingly deployed; OCPP 2.1 emerging.
OCPI (Open Charge Point Interface) — roaming between CPOs.
OICP (Open InterCharge Protocol) — alternative roaming protocol from Hubject.
ISO 15118 — vehicle-to-grid communication (Plug & Charge, V2G).
OSCP, OpenADR — for grid integration.
The CSMS landscape#
Charge Station Management Systems:
Vendor-locked CSMS — many chargers come with manufacturer-locked CSMS.
Vendor-agnostic CSMS — Greenflux, Driivz (Volta acquired), AMPECO, Etrel, EV.energy, Monta, plus various others.
Open-source — Steve, EVerest project.
Cloud-provider native — increasing but mostly through ISVs.
The market is consolidating but still fragmented.
What’s actually working#
Operational charge networks — Tesla Supercharger, Ionity, Electrify America, ChargePoint, EVgo, BP Pulse, Shell Recharge, plus many regional networks.
Roaming integration — cross-network charging via OCPI roaming hubs.
Plug & Charge (ISO 15118) — vehicle authenticates itself; no app required. Increasingly deployed.
Smart charging — charging when grid loads allow, particularly for home charging.
V2G (vehicle-to-grid) in selective pilots and increasing operational deployment.
What’s operationally complex#
Network reliability — uptime variability is a continuing customer satisfaction issue.
Cross-network billing — substantially improving but still imperfect.
Public charger payment — particularly for non-app users (contactless tap, credit card).
Grid integration at scale — substantial but uneven.
Charger maintenance and ops — many networks under-invest in ops.
What’s coming in 2026 and 2027#
Three things to watch:
MCS (Megawatt Charging System) for heavy-duty vehicles.
V2G commercial deployment continues.
Roaming consolidation continues.
