Fully compatible with our integrated wind & storage converter, ideal for desert and plateau mine renewable EPC packages with IEC certifications.
Modular Liquid-Cooled LiFePO4 Containerized Energy Storage System
Our modular liquid-cooled LiFePO4 (LFP) battery energy storage system is containerized, scalable energy storage equipment specially designed for off-grid mine wind-storage microgrid projects. It adopts LiFePO4 cells with built-in liquid cooling thermal management, BMS, EMS and automatic fire suppression system. The modular design allows multiple containers to be paralleled to expand capacity flexibly. It works as DC energy buffer, smoothing wind power fluctuation, supplying peak power for mining EV truck fast charging, supporting black-start and stabilizing heavy impact mining loads. This ESS can be fully integrated into our complete mine renewable EPC package together with wind & storage converter, isolation transformer, step-up transformer and medium/high voltage switchgear.
System Connection & Working Principle
Main Purpose: This modular liquid-cooled LFP ESS stores excess electric energy generated by wind turbines and releases power instantly when wind output drops or mining loads surge. It provides fast peak power support for ore processing plant and electric mining truck charging, and enables black start of the whole mine microgrid.
- Upstream / Output Side of Battery Container (DC Port): DC cable connects to DC bus of Wind & Storage Converter. Battery pack charges when wind power is surplus, discharges when power demand exceeds wind generation.
- Downstream Power Flow: DC power flows into Wind & Storage Converter for DC/AC conversion → Isolation Transformer → Step-up Transformer → MV / 35kV / 66kV Switchgear → Mine end loads (Ore processing plant, mining EV chargers, mine camp).
System Topology: Wind Turbine + Modular Liquid-Cooled LFP ESS → Wind & Storage Converter → Isolation Transformer → Step-up Transformer → MV/35kV/66kV Switchgear → Mine Loads

FAQ
Q1: How does this liquid-cooled LFP ESS connect in mine wind-storage microgrid?
A: It connects on DC side directly to the DC bus of wind & storage converter. The battery stores surplus wind power and discharges to support mining loads when wind drops. After the converter, power goes through isolation transformer, step-up transformer and MV switchgear to mine consumption loads.
Q2: Why liquid cooling instead of air cooling for mining site?
A: Desert & plateau mines have large ambient temperature variation and heavy dust. Liquid cooling maintains consistent cell temperature, avoids hot spots, reduces thermal aging, and provides stable full-power output in high temperature environment, longer service life than air-cooled type.
Q3: Is the system modular? Can we expand capacity later?
A: Yes, fully modular containerized design. You can start with small capacity and add more containers in parallel later when mine power demand increases, without redesigning the whole microgrid.
Q4: Is this battery system compatible with your wind & storage converter?
A: Yes. The DC voltage window is specially matched with our integrated wind & storage converter, well tuned for off-grid mine microgrid, supporting black start and heavy impact mining loads.
Q5: What certifications can you provide for overseas mining tender?
A: IEC 62619, IEC 63056, IEC 62477 test reports, FAT inspection documents, operation manual and technical datasheet for tender submission.
Q6: Typical lead time?
A: Standard liquid-cooled LFP container: 8–12 weeks, depends on capacity and optional customized requirements.
