2508 kWh 1200 kW Mobile Energy Storage and Charging System

The 2508 kWh / 1200 kW Mobile Energy Storage & Charging System combines high-capacity battery storage, power conversion, and six DC fast-charging connectors on a transportable trailer platform. It is designed to bring flexible electrical capacity and high-power vehicle charging to locations where permanent charging infrastructure is unavailable, constrained, or still under development.

The integrated charging system delivers up to 1200 kW through six 200 kW connectors, while the 1500 kW PCS supports AC power conversion for grid-connected and temporary power applications. A liquid-cooled battery compartment, air-cooled electrical compartment, three-level BMS architecture, IP54 enclosure, and C4 corrosion protection support dependable outdoor operation across demanding commercial and industrial environments.

Integrated High-Power Charging and Energy Management

1200 kW DC Fast-Charging System

Six charging connectors provide a combined rated output of 1200 kW, with up to 200 kW available per connector. The 200-1000 VDC output range supports flexible charging for electric buses, airport ground support equipment, commercial vehicles, and temporary public charging deployments.

1500 kW Power Conversion System

The integrated PCS operates across a 615-950 VDC range and provides 230/400 VAC at 50/60 Hz. This configuration enables the system to receive and deliver power in grid-connected, generator-supported, renewable-energy, and temporary power applications, subject to project-specific electrical design.

Hybrid Thermal Management

Liquid cooling manages battery-compartment temperatures, while air cooling serves the electrical compartment. The system is rated for operation from -30°C to 50°C (-22°F to 122°F), supporting deployment across a wide range of climates.

Three-Level BMS Protection

The battery management system uses cell-level monitoring, module-level control, and system-level protection. This layered architecture provides coordinated supervision of the battery system throughout charging, discharging, transport, and standby operation.

Flexible Multi-Source Power and Mobile Charging

The mobile system can be configured within multi-source energy projects that combine utility power, solar generation, or generator support. The central energy storage platform can supply DC fast charging, industrial loads, and temporary site power, while a cloud-connected EMS can support remote operating visibility. Final source connections, protection settings, and operating modes must be engineered for the specific site and local electrical requirements.

Mobile Energy Storage Application Scenarios

Electric Bus Depots

Add temporary charging capacity during fleet electrification, depot construction, charger maintenance, seasonal service increases, or utility interconnection delays.

Airport GSE Charging

Support electric baggage tractors, belt loaders, service vehicles, and other ground support equipment where apron-side charging capacity is limited or temporary.

Emergency Response

Provide relocatable stored energy for field communications, lighting, command facilities, utility restoration work, and essential temporary loads.

Remote Oil and Gas Operations

Deliver mobile electrical capacity for remote field equipment, service bases, maintenance activities, and temporary operations with limited grid access.

Temporary Highway Fast Charging

Expand charging availability during station construction, seasonal travel peaks, corridor trials, charger replacement, or grid-capacity upgrades.

Technical Specifications

Frequently Asked Questions

What is a 2508 kWh mobile energy storage and charging system?

It is a trailer-mounted battery energy storage system that combines 2508 kWh of stored energy with a 1200 kW DC charging system and a 1500 kW power conversion system. It can be relocated to provide temporary charging and electrical capacity where fixed infrastructure is unavailable or insufficient.

How many vehicles can the system charge at the same time?

The charging system includes six connectors rated at 200 kW each, allowing up to six compatible vehicles or machines to connect simultaneously. Actual power allocation and charging time depend on vehicle demand, battery state of charge, control settings, and site conditions.

What charging voltage does the mobile system support?

The DC charging output operates from 200 to 1000 VDC, with an output current range of 2 to 250 A per the supplied product specification.

Can the mobile BESS work with solar, the utility grid, or a generator?

Yes. The system can be integrated into project-specific configurations using solar PV, utility power, or generator support. The final connection method, controls, and protection scheme must be designed for the site.

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

Typical applications include electric bus depots, airport GSE charging, emergency response, remote industrial operations, temporary highway charging, fleet electrification projects, and temporary site power.

How is the battery system cooled and protected?

The battery compartment uses liquid cooling, the electrical compartment uses air cooling, and the BMS provides cell-level, module-level, and system-level protection. The enclosure is rated IP54 with C4 corrosion protection.
