Gateway‑first federated learning

AI that keeps EV chargers online

Evex Tech predicts failures before they happen, triages faults in seconds, and boosts network uptime — all without hardware changes. Built for CPOs, utilities, fleets, and EVSE vendors.

Platform capabilities

Designed to reduce downtime, cut truck‑roll costs, and improve uptime across distributed charging networks.

Predictive maintenance

Forecast component degradation and pre‑empt outages using time‑series and log‑based models optimized for edge gateways.

Fault triage

Automated root‑cause suggestions mapped to OCPP/OEM codes to accelerate first‑time‑fix and reduce mean time to repair.

Federated learning

Share model updates not raw data. Learn across sites while preserving privacy and data residency.

Gateway‑first

No hardware swaps. Works with existing gateways and heterogeneous EVSE fleets.

Interoperable

Standards‑aligned with OCPP 1.6/2.0.1 and vendor‑specific extensions.

Secure by design

Edge encryption, signed model updates, and role‑based access minimize risk and vendor lock‑in.

How it works

01
Connect telemetry

Ingest OCPP events, logs, and sensor streams via your existing gateway or cloud connector.

02
Run edge models

Local models score health and classify faults in near‑real‑time with lightweight artifacts.

03
Federate & improve

Only gradients/weights are shared to the cloud for aggregation. Sites benefit without sharing raw data.

Operational outcomes

↓ MTTR

Slash mean time to repair with instant triage and guided fixes.

↑ Uptime

Fewer surprise outages through early warning signals.

↓ Truck‑rolls

Prioritize the right visit with clear on‑site instructions.

TCO

Reduce total cost of ownership by using what you already have.
