Open-Standards CSMS

Every Session.
Fully Explainable.

v.energy connects what is actually happening at the charger to operational control, business workflows, and energy intelligence. Open protocols are the foundation. Charging success is the outcome.

Platform Architecture

The platform connects charger truth to business value.

Every business outcome depends on what is actually happening at the charger. v.energy connects four layers so operators can move from status monitoring to charging success.

01

Charger Truth

Model, firmware, configuration, OCPP behavior, metering, diagnostics, and readiness state.

02

Operational Control

Monitoring, alerts, remote actions, root-cause visibility, issue ownership, and site management.

03

Business Workflows

Guest charging, fleet readiness, energy products, CPO session optimization, billing, and reporting.

04

Energy Intelligence

Load management, smart charging windows, solar surplus, dynamic signals, and flexibility services.

Research & Certification

Built around what chargers must prove, not just what dashboards display.

Certification thinking changes how a CSMS is built. It forces the product to care about traceability, repeatability, protocol interpretation, charger behavior, metering evidence, and failure conditions before the deployment reaches the customer.

That is why v.energy treats every deployment as a tested operating chain: charger, firmware, protocol messages, vehicle behavior, authorization, energy delivery, pricing, billing, and recovery.

science

Behavior Validation

Charger models, firmware behavior, connector states, meter values, remote commands, and restart patterns are validated against real workflows.

rule

Requirements Discipline

Certification-informed requirements shape how sessions are tested, accepted, monitored, and explained after deployment.

lan

Protocol Evidence

OCPP, OCPI, and ISO 15118 events are stored as evidence trails so operators can see what happened and why.

verified

Deployment Readiness

A site is not ready because chargers are online. It is ready when the end-to-end charging path can be proven.

Broken Session Anatomy

One failed charge can break in six different places.

The driver only sees a failed session. v.energy separates the failure chain so operators can recover the right layer instead of blaming the wrong one.

01

Plug-in

Connector state, cable lock, vehicle handshake, charger readiness.

02

Auth Timeout

Token, room key, roaming contract, Plug & Charge certificate, or backend latency.

03

Energy Block

Load cap, grid constraint, charger fault, vehicle limit, or solar rule conflict.

04

Meter Gap

Missing meter values, incomplete transaction events, or inconsistent CDR evidence.

05

Billing Break

Wrong tariff, failed folio post, settlement mismatch, or missing account mapping.

06

Recovery

Remote action, support path, evidence trail, and prevention for the next session.

Built on Open Protocols.

Open-protocol by design. OCPP compatibility starts the conversation; validated charger behavior, protocol traces, and field diagnostics make the deployment reliable.

Full Observability

Every Session is Explainable.

Every authorization decision, pricing rule, energy adjustment, and billing event is logged and accessible via open REST APIs. No black boxes — every decision has a traceable reason.
