2089kWh 800kW Mobile Battery Energy Storage System

The 2089kWh 800kW Mobile Battery Energy Storage System combines high-capacity battery storage, power conversion, and multi-connector EV charging in one transportable platform. It is designed for fleet charging, temporary charging deployment, mining operations, construction sites, and other locations where fixed grid capacity is unavailable, constrained, or still under development.

With 2,089 kWh of battery capacity, 800 kW of rated charging output, and four 200 kW charging connectors, the system can bring stored energy closer to vehicles and equipment. Its integrated design reduces the number of separate components required at the point of use and supports faster deployment across changing job sites and operating schedules.

A Mobile BESS Built for High Power Charging and Temporary Power

The containerized platform integrates the battery system, a 750 kW PCS, charging equipment, thermal management, controls, and fire protection within a precision sheet-metal enclosure. A voltage platform of 582.4 to 759.2 VDC supports the battery system, while the charging output covers 200 to 1,000 VDC for a broad range of electric vehicles and equipment.

The unit measures 6,058 x 2,440 x 2,590 mm and weighs approximately 20.6 metric tons. Its IP54 enclosure and C4 corrosion-resistance grade support outdoor and industrial deployment when the product is installed and operated according to project requirements.

Integrated Core Systems

800 kW Charging System

The integrated charging system provides 800 kW of rated output through four charging connectors rated at 200 kW each. The 200 to 1,000 VDC output range and 2 to 250 A output-current range allow the system to support varied charging assignments across fleet, construction, and industrial operations.

750 kW Power Conversion System

The PCS provides 750 kW of AC rated power with a 615 to 950 VDC operating range. It supports 230/400 VAC and 50/60 Hz grid frequencies, helping project teams adapt the system to regional electrical requirements and site-specific operating modes.

Dual Thermal Management

The battery compartment uses liquid cooling to manage battery temperature, while the electrical compartment uses air cooling. The specified charging-temperature range is 0 to 50 degrees C, and the discharging-temperature range is -30 to 50 degrees C.

Three-Level BMS Protection

The battery management architecture provides cell-level, module-level, and system-level monitoring and protection. This layered approach supports coordinated battery supervision, operating-status visibility, and protective response across the integrated system.

Flexible Energy Input Storage and Delivery

The mobile BESS can serve as the central energy buffer between available power sources and high-demand loads. Depending on the engineered project configuration, the system can be planned around utility power, generator power, or renewable-energy sources, then dispatch stored energy for EV charging or temporary site loads.

Integrated monitoring and energy-management functions give operators a centralized view of system status and energy flow. Final source connections, protection settings, operating modes, and site interfaces should be confirmed during project engineering.

Technical Specifications

Applications for Mobile Energy Storage and Charging

Heavy Duty Fleet Charging

Deploy stored energy near electric truck fleets to add charging capacity during depot expansion, peak operating periods, infrastructure upgrades, or temporary route support.

Roadside Mobile EV Charging

Mount the system on a suitable transport platform to bring temporary charging support to highway service areas, remote parking locations, testing programs, or planned roadside operations.

Mining Power Supply

Position energy storage closer to electric mining vehicles and equipment where grid access is limited, site layouts change frequently, or charging demand moves with the operation.

Construction Site Power

Support temporary electrical loads and electric construction equipment while permanent utility capacity is unavailable or while site power infrastructure is being installed.

Large Event Power

Provide transportable stored energy for event service areas, temporary facilities, production equipment, and other planned loads that require flexible deployment.
