2926 kWh 1200 kW Mobile Battery Energy Storage System and EV Charging Station

The 2,926 kWh mobile battery energy storage system combines high-capacity LFP battery storage, a 1,200 kW DC charging system, and a 1,000 kW power conversion system in a transportable platform. Six 200 kW charging connectors support electric excavators, heavy equipment, and commercial fleets where fixed charging infrastructure is unavailable, constrained, or still under construction.

Designed for mines, ports, airports, construction projects, and remote fleet operations, the system brings stored energy closer to the equipment that needs it. Its integrated architecture reduces the need to assemble separate battery, PCS, charging, cooling, and control equipment at each temporary site.

Integrated Mobile Power and Charging Systems

The platform coordinates energy storage, power conversion, DC charging, thermal management, and multilevel battery protection within one mobile enclosure. Operators can deploy the unit near high-demand equipment and use its six charging outputs to serve multiple charging positions from a single system.

High-Power DC Charging System

The charging system provides 1,200 kW of total rated output through six 200 kW charging connectors. A 200 to 1,000 VDC output range supports a broad range of high-voltage electric equipment and fleet charging requirements. The specified output current range is 2 to 250 A.

1000 kW Power Conversion System

The integrated PCS is rated at 1,000 kW AC. It operates from 615 to 950 VDC and supplies 230/400 VAC at 50 or 60 Hz. This AC path can support compatible temporary site loads and power distribution equipment, subject to project-level electrical design and connection requirements.

Hybrid Thermal Management

Liquid cooling manages the battery compartment, while air cooling serves the electrical compartment. The specified operating temperature range is -30°C to 50°C, equivalent to -22°F to 122°F. Separate cooling methods address the different thermal conditions within the battery and power electronics areas.

Three-Level BMS Protection

The battery management system coordinates protection at the cell, module, and system levels. This layered structure monitors battery operating conditions and supports coordinated control across the energy storage system.

Energy Flow and Control Architecture

The LFP battery system feeds a central DC bus. From that bus, stored energy follows one of two primary power paths: the DC charging system supplies six charging connectors, while the PCS converts DC energy for compatible AC distribution. The BMS, energy management system, and thermal management system provide monitoring, coordination, and protection across the platform.

Battery Energy Storage

The system uses 314 Ah LFP cells with a rated cell energy of 1,004.8 Wh. The battery voltage range is 582.4 to 759.2 VDC, and the stated battery cluster configuration is 7P208S × 2. Total battery capacity is 2,926 kWh.

Separate DC Charging and AC Power Paths

The 1,200 kW charging system supplies the six DC charging outputs directly from the DC architecture. The 1,000 kW PCS provides a separate conversion path for AC loads. Keeping the two ratings distinct helps project teams size charging demand and temporary AC power requirements correctly.

Applications for Mobile Energy Storage and Charging

A transportable energy and charging platform is useful when equipment moves between projects, permanent grid capacity is limited, or charging demand changes faster than fixed infrastructure can be installed. The following applications align with the system's energy capacity, charging configuration, and mobile form factor.

Mining Operations

Deploy stored energy near electric excavators, haul trucks, and other mine equipment to support charging at changing work areas. The mobile format can follow site development as active zones move across a large mine.

Port Electrification

Provide temporary or supplemental charging for electric terminal tractors and cargo-handling equipment during fleet expansion, yard reconfiguration, or charging infrastructure construction.

Airport Ground Support

Support electric ground service equipment and airside vehicle fleets where operations require flexible charging capacity across gates, maintenance areas, and remote stands.

Construction Sites

Supply compatible electric heavy equipment and temporary AC site loads from a transportable platform. The system can be repositioned as construction phases and equipment locations change.

Remote Fleet Charging

Extend charging coverage to logistics staging areas, temporary depots, and remote routes beyond fixed charging networks. Six charging connectors help organize multiple fleet charging positions at one deployment point.

Frequently Asked Questions

What is a 2926 kWh 1200 kW mobile BESS

It is a transportable battery energy storage and charging platform with 2,926 kWh of LFP battery capacity and 1,200 kW of total rated DC charging output. It also includes a 1,000 kW PCS for compatible AC power applications.

How many vehicles or machines can connect to the system

The charging system includes six 200 kW charging connectors. Actual charging power allocation and compatibility should be confirmed for the equipment, voltage, current, connector, and operating plan used in each project.

Can the mobile BESS charge electric excavators

The system is designed for high-power mobile charging applications and has a 200 to 1,000 VDC charging output range. Compatibility with a specific electric excavator must be verified against its charging interface, voltage range, current limits, and charging protocol.

What is the difference between the 1200 kW charging rating and the 1000 kW PCS rating

The 1,200 kW figure is the total rated output of the DC charging system. The 1,000 kW figure is the rated AC power of the PCS. They describe two different power paths within the integrated platform.

How is the battery system cooled

The battery compartment uses liquid cooling. The electrical compartment uses air cooling. This hybrid design applies a dedicated cooling method to each equipment area.

Where can a mobile battery energy storage and charging system be used

Typical applications include mining equipment charging, port vehicle electrification, airport ground support fleets, construction projects, remote logistics operations, and temporary charging during permanent infrastructure upgrades.

What environmental protection does the enclosure provide

The enclosure is rated IP54 and has a C4 corrosion protection grade. The specified operating range is -30°C to 50°C (-22°F to 122°F), with relative humidity up to 95% RH under non-condensing conditions.
