Grid‑Forming Liquid‑Cooled Container BESS & PCS Solution
Our grid‑forming energy‑storage portfolio features high‑performance PCS (Power Conversion System) and liquid‑cooled containerized BESS (Battery Energy Storage System). It stands out for industry‑leading black‑start and full off‑grid operation capability. The solution is widely deployed for weak‑grid / off‑grid open‑pit mines, acting as power buffer for heavy‑duty mining‑truck charging stations, hybrid PV‑diesel‑storage micro‑grids, peak‑shaving and load‑smoothing for mining processing plants.
Important Note: Standard container‑type BESS hardware is for surface open‑pit mine deployment only. Underground explosive‑risk zones require complete explosion‑proof modification plus local mining‑safety certification such as IECEx.

Precise cell temperature control, reduce internal temperature difference; IP54‑IP55 cabinet rating, optional C3‑C5 anti‑corrosion treatment for coastal, high‑dust, high‑altitude mining locations. Wide operating temperature range:‑20℃ ~ +55℃, suitable for tropical, alpine open‑pit mine conditions. Pre‑commissioned in factory, shorten mine‑site installation & commissioning cycle.
- Perfect power‑buffer for mining‑truck megawatt‑charging load impulse: Absorb sharp peak power draw from simultaneous multi‑unit mining‑truck fast‑charging. Effectively avoid mine‑site transformer overload, defer costly grid‑capacity expansion investment. Cooperates well with third‑party megawatt mining‑truck chargers to complete full PV‑storage‑charging integrated solution.
- Complete EMS energy‑management platform & multi‑protocol openness: Self‑developed EMS energy‑management system realizes unified dispatching of battery, PV, diesel‑generator and EV‑charging loads. Open Modbus‑TCP / IEC‑61850 interfaces, supports docking with mine MES system, remote monitoring, energy‑statistics and intelligent load scheduling.
- High‑safety multi‑layer protection design: Multi‑level fire‑suppression solution, real‑time insulation monitoring, battery cell status real‑time tracking. Supports multi‑unit parallel expansion for scaling from hundreds kWh up to multi‑MWh large‑scale mine micro‑grid projects. Global mainstream certifications available for overseas mining projects.

Key mine‑site tip: Container‑type units can be paralleled to build large‑scale energy‑storage plants. For mining‑truck charging peak‑buffering, typical matching suggestion: every 2‑3 units of megawatt mining‑truck charger shall be matched with at least one 2.5MW/5MWh container BESS as power buffer.
Mine‑Site Key Considerations
- Grid‑connected mode: Works as grid‑following storage for mine sites with existing stable grid, for peak‑shaving and backup power.
- Off‑grid / micro‑grid mode: Enable grid‑forming + black‑start function, cooperate with photovoltaic and diesel‑genset to realize 24‑7 continuous mine power supply.
- Matching with mining truck chargers: BESS cannot replace EV chargers. It works as power buffer; mining‑truck charging piles shall be sourced from third‑party professional charger suppliers.
- Environmental customization: For coastal salt‑fog or heavily dusty mine area, select C4/C5 anti‑corrosion enhanced version. Regular external cabinet cleaning maintenance is required.
FAQ
Can this system run totally off‑grid for remote mine sites without utility power?
Yes. Our grid‑forming PCS supports black‑start and full off‑grid micro‑grid operation. It can form stable AC bus together with solar PV and diesel generator to supply power for mine production facilities and mining‑truck charging depots. System capacity configuration needs to match actual mine total load.
Can your BESS work together with third‑party brand mining‑truck chargers?
Yes. We adopt standard open communication protocols. Our container‑type BESS serves as power‑buffer energy‑storage backend. Mining‑truck megawatt chargers are supplied separately by dedicated charging‑equipment vendors. Joint logic debugging will be required during site commissioning.
How about the adaptability for high‑temperature, salt‑fog, dusty open‑pit mine?
Liquid‑cooled BESS provides excellent thermal management. We offer optional C3‑C5 anti‑corrosion cabinet upgrade for coastal & harsh mine environment. Standard IP54‑IP55 enclosure resists dust and rain; regular surface cleaning maintenance is still required in heavy‑dust mining zones.
Can capacity expand after the container‑BESS station is put into operation?
Yes. Modular parallel architecture supports capacity step‑by‑step expansion. Additional container units can be added without replacing the core control system. Civil‑construction space and transformer margin should be reserved in the initial mine‑site planning phase.
Can the container‑BESS be used in underground mine working faces?
Standard container BESS is designed for surface open‑pit mine only. Underground deployment needs complete explosion‑proof modification plus IECEx / local mining safety certification. Standard products are not qualified for underground hazardous‑zone deployment.
What certifications are available for overseas mining projects?
Core PCS & BESS obtain international mainstream certifications. For target‑market specific certification requirements, please confirm in advance in project early stage.
