EV Bus Charging Infrastructure

Bài toán

Depot chargers, transformers and building loads share one grid connection, and without live data the depot risks peak charges or buses not charged by morning.

Tổng quan giải pháp

MILESGO gateways collect data from EV chargers (Modbus interface or charging platform API), electricity meters, transformer temperature and tap monitors, power quality analysers over Modbus TCP / Modbus RTU, and deliver it to the energy management system, third-party platforms (HTTP API), the utility SCADA (IEC 104 / IEC 61850) as MQTT / OPC UA / IEC 60870-5-104. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

EV chargers (Modbus interface or charging platform API)
electricity meters
transformer temperature and tap monitors
power quality analysers

Protocol path

Modbus TCP / Modbus RTU → MQTT / OPC UA / IEC 60870-5-104

Implementation checklist for the project manager

Charger data comes from each charger’s Modbus interface, its energy meter or the charging platform’s API; confirm what each model exposes (OCPP is not handled by the gateway).
Any set-point control of PV or storage must follow the grid-connection requirements; start with monitoring only.
Record CT ratios, meter IDs and multipliers in the point table; wrong multipliers are the usual cause of billing errors.
Where equipment only offers a vendor API or cloud, confirm access rights, data rate and costs with the vendor before design.
Commission in read-only mode first; enable write / control points only after the client approves each one.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.

Project deliverables

Signed point table and protocol mapping
Gateway configuration files and backups
IP address plan and network drawing
FAT and SAT test records
As-built documentation and operator training

Kiến trúc hệ thống

Field layer: EV chargers (Modbus interface or charging platform API), electricity meters, transformer temperature and tap monitors, power quality analysers, connected over Modbus TCP / Modbus RTU. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the energy management system, third-party platforms (HTTP API), the utility SCADA (IEC 104 / IEC 61850), which receives the data as MQTT / OPC UA / IEC 60870-5-104. Remote access for maintenance runs over VPN rather than open internet ports.

Các bước triển khai

1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.
