European contractors and rental companies are bringing electric excavators, loaders, dumpers and site vehicles onto their projects, and each machine class has its own charging needs. A mobile BESS charger manufacturer serving this market should offer a range that scales from compact machines to heavy equipment. MPMC's BCH Series spans 80 kW to 600 kW of DC output and 70 kWh to 1,075 kWh of storage, with DC-side coupling that delivers up to 87% discharge efficiency and power conversion optimised specifically for electric construction machinery.

Sizing Chargers by Machine Class

Compact Machines and Site Vehicles

The BCH-80-70 delivers 80 kW through a liquid-cooled CCS2 260 A gun on a 7 m cable from 70 kWh of storage. Weighing 880 kg and measuring 1,460 × 780 × 1,200 mm, it suits compact excavators, compact loaders and site vans, and six units ship in a 20-foot container.

Mid-Size Excavators and Loaders

The BCH-275-200 delivers 150 kW through two CCS2 guns from 203.5 kWh. It travels on a 3.5 t heavy-duty trailer, has an integrated forklift pocket for repositioning, and a plug-and-play fast output box removes on-site wiring. Its 125 kW AC output also supplies site cabins and tools.

Heavy Machinery and Multi-Machine Sites

For heavy equipment, the BCH-600-400 delivers 400 kW from 407 kWh, the BCH-800-600 delivers 600 kW with 1C charge and discharge from 610.6 kWh, and the BCH-500-1000 delivers 500 kW from 1,075 kWh in a 20-foot container. In Norway, a 2 MWh BCH system with CCS2 output of 360 kW at 400 A charges rental construction machinery at a site with no grid access, with no diesel generator set needed. The BCH-275-200 and larger models take energy from the grid, a generator set or solar, and the CCS2 DC input recharges the BCH-275-200 in about one hour.

Engineered for Construction Sites

Construction charging equipment works in dust, rain and cold. BCH units use fully sealed liquid-cooled battery packs that keep dust out, blade LFP cells in a sandwich structure tested for fire, water immersion, collision and crushing, and 6.7°C precision temperature control, while a 390 Wh/L energy density keeps units compact. Optional CCS1, GB/T and CHAdeMO connectors suit machines from different markets. C4 anti-corrosion coating is standard, with C5 available on the BCH-800-600 and BCH-500-1000, and units operate from -20°C. Charging guns support simultaneous charge and discharge, and every unit reaches full operation within 24 hours of arrival. The EMS with 4G reports each unit's state of charge, so site managers can plan charging around breaks and shift changes, and integrated SCADA and EMS automate energy management to reduce labour on site.

Working With Dealers and Rental Companies

Electric machinery sells and rents more easily when charging comes with it. Equipment dealers can offer a matching BCH unit with each machine, and rental companies can add BCH units to their hire fleets; eight BCH-275-200 units were recently exported to Sweden for rental use. Remote monitoring through the EMS with 4G and OCPP 1.6, and optional RFID payment, let rental companies bill for energy as well as equipment. For distributors of new-energy construction equipment, MPMC also offers OEM customisation and private-label arrangements, and the BCH-275-200 and larger models carry a 3-year system warranty and a 5-year battery performance warranty.
