02 Architecture

The modular energy stack

CSMS is one module on a stack you can extend.

Products on top, Fabric in the middle, devices and data sources at the edge. Every product runs on the same Fabric, so a second product works from the devices and site model the first one already connected.

/products

/fabric
Voltra Fabric
The same platform under every product
How Fabric works
- Connect
  Devices over nine protocols, through versioned device profiles.
- Model
  Every device and system as one vendor-agnostic graph.
- Configure
  Devices made to work together from the model.
- Maintain
  Connections and the model kept current as firmware and sites change.

/edge
Devices and data sources
Connected where they are, over the protocols and formats they already use.
- OCPP
- OCPI
- Modbus
- MQTT
- SNMP
- IEEE 2030.5

03 Features

CSMS, feature by feature.

Any OCPP charger

Connect hardware from any vendor that speaks OCPP, with no proprietary lock-in.

Load balancing

Share a site’s power across chargers and stay under the service limit.

Pricing engine

Time-of-use, session, idle and energy pricing, per site or per driver group.

Roaming over OCPI

Let drivers from partner networks charge on your sites, and yours on theirs.

Driver access

RFID, app and QR authorization, with role-based access for operators.

Otto for small sites

A lightweight web CPMS for deployments that need to start small.

Native integrations with the hardware you already use.

Voltra talks to devices over the protocols they already speak, so you keep the equipment you have. Each vendor below is mapped to one device model, so a new site comes online without custom integration work.
