Development Scope
Device and interface access
Connect to the authorization interface of BMS, PCS or EMS to distinguish battery, converter and system-level operating data, faults and command permissions.
Product business functions
Develop authorization interfaces for BMS, PCS or EMS to develop status and alarm reporting, data caching, logs and parameter management.
Platform and data connection
Combined with the business link of main controller and instrument → data and order status → 4G → enterprise operation platform → operation and maintenance processing, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The original system is responsible for charge and discharge protection and key control; remote configuration only covers authorized parameters, and confirms value constraints and validity conditions.
Data and Operational Workflow
Device telemetry → Status and alarm classification → Local cache → 4G return → Enterprise backend query, diagnosis and maintenance.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business processes and parameters: BMS/PCS/EMS interfaces, data levels, parameter permissions and protection responsibilities.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Check the equipment level, unit and fault code item by item. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test alarm timing, recovery and repeated reporting. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify permissions, scope and read confirmation of remote parameters. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
4G Does the gateway bear the energy storage protection function?+
This gateway service mainly covers data and operation and maintenance links. Protection logic, control cycles and safety functions should be undertaken by the existing BMS, PCS or EMS according to the system design, and relevant changes need to be defined and verified separately.
Can I entrust only part of the functions of the energy storage device monitoring gateway?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing data and target boundaries, first check the "BMS/PCS/EMS interface, data level, parameter permissions and protection responsibilities", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the BMS/PCS/EMS interface, data level, parameter permissions and protection responsibilities; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
