Mines are electrifying haul trucks, loaders, drills and support vehicles, and as the working face moves, fixed charging infrastructure takes time to follow. A mobile energy storage charging station brings high-power DC charging to the pit and moves with the mine plan. MPMC, a Shanghai-based manufacturer with mining power experience from Australia to Chile and BCH references in Norway, Sweden and the UK, offers three high-power BCH models for heavy equipment.

High-Power Charging at the Pit

Choosing the Model for Heavy Equipment

The BCH-600-400 delivers 400 kW of DC charging from 407 kWh and is designed for heavy-duty machinery and mining support. The BCH-800-600 delivers 600 kW, with 640 kW peak, and 1C charge and discharge from 610.6 kWh for high-intensity duty. The BCH-500-1000 stores 1,075 kWh in a 20-foot container and delivers 500 kW, acting as a large off-grid power hub. All three charge through dual 350 A CCS2 guns across DC 50 to 1,000 V, and their charging guns support simultaneous charge and discharge.

Feeding the Chargers on an Off-Grid Site

BCH units take energy from mine generator sets through PowerLock AC inputs of up to 560 kW, from solar through a dedicated solar input, and from other storage through CCS2 DC input. MPMC's 400 kVA methanol distributed power station, controlled by a DEIF AGC150, combines with BCH units from the BCH-275-200 to the BCH-800-600 to form an integrated off-grid green power system for electric equipment, and SPK mobile solar plants of up to 231.84 kWp add daytime generation. Where a mine supply is modest, the BCH buffers it: the BCH-800-600 draws 280 kW and delivers up to 640 kW at peak. The BCH-600-400 ships one unit per 20-foot container or three per 40-foot container.

Note: The table shows the three high-power models; the BCH Series also includes the BCH-80-70, BCH-60-70 and BCH-275-200.

With two guns per unit, a BCH can charge two machines at once, and units are repositioned as the pit develops; the BCH-500-1000 travels in its 20-foot container like any other piece of containerised mine equipment, while its 500 kW of UPS-grade AC output can also supply workshops and pumps.

Built for Mine Conditions

Liquid-cooled battery packs are fully sealed to keep dust out, a design MPMC product data describes as ideal for mines and construction sites, an explosion-proof breather on the BCH-800-600 and BCH-500-1000 provides precision pressure relief in extreme conditions, and C4 anti-corrosion coating is standard with C5 available. Units operate from -20°C to +50°C and at altitudes up to 3,000 m, with derating above 2,000 m, and carry aerosol fire protection. Blade LFP packs are tested for fire, water immersion, high-impact collision and crushing, with 6,000 cycles at 90% depth of discharge.

Every unit reaches full operation within 24 hours of arrival, and the EMS with 4G connectivity and OCPP 1.6 allows remote monitoring from the mine control room, so charging can be scheduled around shift changes and haul cycles.

Part of a Complete Mine Power System

Because MPMC also builds generator sets, mobile battery storage, lighting towers and hybrid power stations, a mine can source its charging and its power supply from one manufacturer, coordinated through MPMC's EMS and SCADA with Starlink satellite backup for remote sites. MPMC's mining power references include 5.2 MW in Australia, 3.793 MW in Peru and a 1.2 MW camp station in Côte d'Ivoire.
