Service Overview

TREASURE provides one-stop engineering service around our energy storage systems and EV charging products.

Instead of only shipping hardware, we support you from early-stage planning to final acceptance, making sure every project is technically sound, aligned with site conditions, business targets and long-term operation.

Our service scope covers:

Pre-sales consulting and feasibility study
System design and configuration for BESS and EV charging
OEM/ODM customization for products and systems
Project implementation support and commissioning coordination
Training and documentation for your operation team

Service Workflow

This clear workflow helps both sides manage expectations, schedule resources and control project risks. For most projects, our service workflow can be summarized into six steps:

1

Initial Inquiry & Data Collection

Understand site info, loads, EV fleet, grid and goals.
2

Preliminary Proposal & Quotation

Provide solution concept, configuration suggestion and budgetary quotation.
3

Technical Clarification & Contract

Finalize technical scope, responsibilities and schedule.
4

Detailed Design & Manufacturing

Complete design, manufacturing and FAT, covering functional, communication, safety and performance verification.
5

Delivery, Installation & Commissioning

Coordinate shipping, support installation and commissioning until acceptance.
6

Transition to Operation & Support

Handover to your O&M team and connect to our support and monitoring services.

System Design & Configuration

Based on the agreed technical route, we provide detailed system design support for both energy storage and EV charging projects.

Typical design work includes:

Selecting appropriate cabinet ratings or battery capacity (e.g. 100kW/233kWh, 135kW/261kWh or customized)
Defining PCS, transformer and protection configuration
Choosing the right combination of fixed DC chargers, mobile charging robots and V2V devices
Designing communication topology and integration with EMS / SCADA systems
Preparing system single-line diagrams and interface descriptions

With experience across C&I BESS, EV charging depots, mobile charging deployments and customized charging applications, we help you avoid common design pitfalls and ensure the system is ready for implementation.

OEM / ODM & Customization Service

We work closely with your technical team to ensure compatibility with your existing platforms and long-term product roadmap.

For brands, system integrators and OEM partners, TREASURE offers flexible customization service:

01

Branding and industrial design adjustments for cabinets and mobile charging robots
02

Capacity, voltage and cabinet layout customization for different projects
03

Integration of customer-specified communication protocols and interfaces
04

Custom functions in BMS/EMS and user interfaces according to your operating workflow

Engineering Service for C&I Energy Storage and EV Charging Integration

Every site is different. To design the right C&I energy storage solution, we usually start with your basic data: load profile, tariff structure, grid connection conditions, existing PV or EV charging facilities and your business goals.

TREASURE’s engineering team will then propose an initial system configuration, expected benefits and an implementation roadmap.
