BMS EDGE CONNECTIVITY

BMS Edge Connectivity

Electric machine OEMs ship battery systems without continuous field visibility. The BMS tracks cell voltage, thermal events, fault codes, and charge-cycle history, but that data remains on the machine after it leaves the factory. Melqart Systems deploys a CAN-to-cloud edge gateway on each machine, delivering real-time SOC, SOH, fault streams, and thermal telemetry to the fleet platform without modifying BMS firmware.

Battery Data Visibility Gap

The BMS leaves the factory, but its data remains on the machine.

Electric machine OEMs invest heavily in battery technology but lose visibility when machines enter service. The BMS tracks cell voltage, thermal events, charge cycle counts, fault history, and degradation curves. Without an edge connectivity layer, this data does not reach engineering teams. Warranty disputes remain unresolved because field evidence is missing. Field failures are diagnosed by replacing parts rather than reading fault logs. Battery degradation patterns that could inform the next product generation are lost. Melqart Systems extracts structured BMS telemetry from the CAN bus or RS-485 interface, normalizes it at the edge, and delivers it continuously to the fleet platform.

Real-time battery health streaming

Continuous SOC, SOH, cell voltage, and temperature telemetry from every machine in the field, not just when a fault occurs.

Fault-code transparency

BMS fault codes and error events streamed to your platform the moment they occur, with contextual operating data to support remote diagnosis.

Non-invasive CAN integration

Edge gateway reads from the CAN bus or RS-485 interface without firmware changes to the existing BMS, compatible across battery suppliers.

Fleet electrification visibility

Unified telemetry layer across your electric machine range: one data pipeline for SOC, SOH, charge cycles, and thermal events across every model.

The BMS leaves the factory, but its data remains on the machine.
The Challenge

Where current approaches fall short

Warranty disputes without field evidence

Without field BMS telemetry, teams cannot distinguish genuine product failure from operator misuse or improper charging. Warranty claims are resolved by cost rather than data, and engineering teams gain no product insight from them.

Battery degradation goes undetected until failure

Cell voltage drift, capacity loss, and thermal anomalies develop over hundreds of cycles. Without continuous SOH monitoring from the field, degradation is invisible until it becomes a field failure or a customer complaint.

Mixed electric fleets lack unified telemetry

As OEMs electrify their machine range, each model may use a different BMS supplier, protocol, or data format. Without an OEM-agnostic edge layer, each product line becomes a separate, isolated telemetry problem.

Architecture

How BMS edge connectivity works

Melqart Systems connects directly to the machine's BMS interface, normalizes battery telemetry at the edge, and delivers structured data to the fleet platform over cellular connectivity without modifying BMS firmware.
