Who we build energy systems for
EV charging manufacturers & network operators
You build or operate charging stations (EVSE) and need OCPP-compliant firmware, a back-end that scales, billing-grade metering, and the path to ISO 15118 Plug & Charge. We design the charger electronics and firmware and the network/CSMS integration, with Measurement Canada and payment considerations handled from the start.
Utilities & grid-equipment OEMs
You build or operate grid-edge equipment — reclosers, RTUs, smart meters, substation devices — and need IEC 61850 or DNP3 integration, NERC CIP-aware security, and reliable field firmware. We engineer the device and its secure communication to the SCADA/DERMS layer.
Microgrid, storage & DER innovators
You’re building distributed energy resources — solar, storage, microgrid controllers — and need IEEE 1547-compliant interconnection logic, monitoring, and cloud analytics. We build the controller and the data layer that keeps your assets coordinated and visible.
Standards and frameworks we work to
| Standard | Scope |
|---|---|
| OCPP 1.6 / 2.0.1 | Open Charge Point Protocol — EVSE ↔ network (CSMS) |
| ISO 15118 | Vehicle-to-grid communication, Plug & Charge |
| IEEE 1547 | Interconnection of distributed energy resources |
| IEC 61850 | Substation automation & communication |
| DNP3 / Modbus | SCADA & grid-device communication protocols |
| NERC CIP | Critical-infrastructure protection (cybersecurity) — design awareness |
| Measurement Canada | Billing-accuracy requirements for energy/EV metering |
| IEC 62443 | Cybersecurity for industrial & energy control systems |
Transparency note: Amotus is an engineering firm. We design devices that meet the requirements of these standards and that are submitted for the appropriate approvals (OCPP certification, Measurement Canada approval of a metering device) by the responsible party. We don’t issue those approvals ourselves; we make sure the design and documentation are built to pass them.

Frequently asked questions — energy & EV charging
How do you handle data security?
Security is a first-class design requirement, not an afterthought. We work to SOC 2 Type II–audited practices (Groupe Vectanor), with zero-trust architecture, mTLS between devices and cloud, encryption in transit and at rest, and data residency in the region you require on our multi-region Fundamentum platform (Canada, US, Europe, and more). Your data stays yours, with clear ownership and open export.
What is OCPP and do I need it?
OCPP (Open Charge Point Protocol) is the open standard for communication between an EV charging station and a central management system (CSMS). If you want your chargers to work with multiple back-ends, avoid vendor lock-in, and participate in roaming and smart-charging, OCPP is essentially mandatory. Most procurement and many incentive programs now require it.
OCPP 1.6 or 2.0.1 — which should I implement?
OCPP 1.6 is widely deployed and well-supported by existing back-ends. OCPP 2.0.1 adds richer smart-charging, improved security (built-in certificate management), device management, and better support for ISO 15118 Plug & Charge. New designs increasingly target 2.0.1, but back-end support and your network’s roadmap matter. We help you choose, and we can design for a clean migration path.
What does Measurement Canada require for EV billing?
If you bill EV charging by energy delivered (per kWh), the metering generally must be approved for accuracy under Measurement Canada’s framework for electricity measurement. That drives the choice of metering components, accuracy class, calibration, and tamper protection. We design the metering subsystem to be submittable for approval rather than discovering the requirement late.
IEC 61850 or DNP3 for grid devices?
DNP3 is widely used in North American utilities for SCADA and is efficient over constrained links. IEC 61850 is richer, object-oriented, and dominant in modern substation automation, with strong interoperability and engineering tooling. The choice depends on your utility’s existing infrastructure and the device’s role. We implement and integrate either, and bridges between them.
How do you address NERC CIP and energy cybersecurity?
For devices on or near the bulk electric system, we design with NERC CIP and IEC 62443 in mind: secure boot, signed firmware, encrypted communication, access control, logging, and a Software Bill of Materials. The utility owns the formal CIP compliance program; we ensure the device supports it rather than undermining it.
Can you do vehicle-to-grid (V2G) and Plug & Charge?
Yes. ISO 15118 enables Plug & Charge (the car authenticates and bills automatically) and bidirectional V2G. We design charging firmware with the ISO 15118 communication and certificate handling required, coordinated with your OCPP back-end.
What is the typical duration and cost of an energy project?
OCPP firmware for a new charger is often 6 to 12 months; a billing-grade metering subsystem or an IEC 61850 grid device with conformance testing can run longer. A focused OCPP firmware effort commonly lands in the CAD $120,000 to $300,000 range depending on hardware and certification scope. These are industry-typical ranges; your quote depends on scope.
