DERMS and EV Telemetry Architecture Diagram

Distributed Energy Resource Management (DERMS) & EV Fleet Telemetry

A CleanTech grid operator and commercial EV fleet network faced substation transformer overloads, peak tariff penalties, and disconnected battery storage systems during simultaneous fleet charging windows.
Codixon engineered an edge-to-cloud DERMS and EV telemetry platform integrating OpenADR 2.0b automated demand response with OCPP 2.0.1 smart charging orchestration and real-time Battery Energy Storage System (BESS) telemetry, cutting peak substation grid draw by 34%.

Technical Constraints

Distributed Energy & EV Grid Bottlenecks

Uncoordinated fleet charging surges, protocol fragmentation across hardware vendors, and isolated battery storage threatened local grid stability.

Substation Transformer Overloads

Grid Overload

Unmanaged simultaneous commercial fleet plug-ins created localized distribution circuit spikes, risking physical transformer blowouts and peak utility fines.

OCPP Protocol Incompatibilities

Protocol Drift

Mixed deployments of OCPP 1.6J and 2.0.1 across multi-vendor DC fast chargers caused lost session states and failed remote charging profile adjustments.

Siloed Battery Storage (BESS)

Storage Silos

On-site commercial solar inverters and lithium-ion battery banks operated independently from charger loads, missing peak-shaving dispatch opportunities.

Sluggish Demand Response Eventing

Signal Latency

Utility OpenADR curtailment signals took minutes to parse and propagate across depots, missing rapid ancillary frequency regulation response windows.

Engineering Blueprint

Dynamic DERMS & High-Velocity Telemetry Fabric

A cyber-secure, event-driven architecture orchestrating automated grid event handling, low-latency charger control, and battery telemetry.

01
DISPATCH

OpenADR 2.0b Virtual Top Node (VTN/VEN)

Built a certified OpenADR client translating utility price signals and emergency curtailment events into immediate microgrid operational setpoints.

02
ORCHESTRATION

High-Throughput OCPP 2.0.1 Charging Gateway

Engineered WebSocket microservices managing persistent bi-directional charging sessions, dynamic smart charging profile distribution, and sub-second current throttling.

03
TELEMETRY

Real-Time BESS Inverter & Sensor Telemetry

Streamed Modbus and SunSpec telemetry from solar inverters and battery racks into a time-series pipeline, tracking State-of-Charge (SoC) and cell thermal health.

04
BALANCING

Algorithmic Local Grid Balancing Loop

Implemented mathematical optimization loops that automatically discharge stationary battery buffers and dynamically throttle EV charge rates to preserve local transformer headroom.
