522kWh / 320kW Mobile Energy Storage & Charging Systems

Bring battery storage and high-power DC charging directly to the point of use. This mobile system integrates a 522kWh battery, a 250kW PCS, and a 320kW DC charging system on a towable four-wheel platform. It supports temporary power, off-grid charging, renewable energy utilization, peak-demand management, and resilient backup power without requiring permanent infrastructure.

With a battery voltage range of 728-949 VDC, two 160kW charging connectors, liquid cooling for the battery compartment, and air cooling for the electrical compartment, the system is built for reliable operation across demanding commercial and industrial environments.

Mobile Battery Storage and DC Charging in One Platform

The integrated architecture reduces the need to coordinate separate battery containers, power conversion equipment, and charging cabinets. Energy can be received from the utility grid, solar PV, wind power, or a generator, stored in the battery, and delivered to vehicles, construction equipment, commercial facilities, or temporary loads.

A towable chassis helps operators move energy capacity between sites, while the enclosure provides IP54 ingress protection and C4 corrosion resistance for outdoor deployment. Remote-ready monitoring supports operating visibility, energy management, and preventive maintenance.

Core Systems Built for Reliable Performance

320kW DC Charging System

Two 160kW DC charging connectors provide a combined rated output of 320kW. The 200-1,000 VDC output range supports a wide range of compatible commercial vehicles and electric equipment, while the 2-250 A output-current range provides flexible charging control.

250kW Power Conversion System

The bidirectional 250kW PCS operates across a 615-950 VDC range and supports 230/400 VAC at 50/60 Hz. It manages energy transfer between the battery, AC sources, and connected loads for charging, discharging, peak shaving, and backup-power operation.

Dual-Mode Thermal Management

Liquid cooling helps maintain stable battery temperatures, while air cooling manages the electrical compartment. This dual-mode design supports consistent performance, operating efficiency, and battery protection under changing load and ambient conditions.

Three-Level BMS Protection

The battery management system coordinates protection at the cell, cluster, and system levels. Real-time monitoring, coordinated cluster protection, and centralized system control help identify abnormal conditions and support safe, reliable operation.

How the Mobile Energy Storage and Charging System Works

The system can receive power from the utility grid, solar PV, wind generation, or a generator. Stored energy can then be supplied to EV fleets, heavy equipment, construction sites, and temporary loads. A remote monitoring connection gives operators visibility into system status and energy flow.

This flexible energy path allows one mobile asset to support both charging and power-supply applications. Operators can charge the battery during low-demand periods, move the system to the point of use, and discharge when grid access is limited, demand is high, or backup power is required.

Five Flexible Applications

Renewable Energy Integration

Store energy from solar PV and wind generation, smooth intermittent output, and increase the amount of renewable energy available for on-site use or charging.

Peak Shaving and Energy Arbitrage

Charge during off-peak hours and discharge during peak-demand periods to reduce demand spikes, improve facility load management, and lower energy costs where time-of-use pricing applies.

Grid Support Services

Use responsive battery capacity to support grid stability through frequency regulation, voltage support, and reserve capacity, subject to local interconnection and market requirements.

Emergency Backup Power

Keep critical loads operating during grid outages and strengthen power resilience for hospitals, data centers, commercial facilities, and other essential operations.

Temporary and Mobile Power

Deploy power and charging capacity quickly to construction sites, events, remote operations, and projects where permanent electrical infrastructure is unavailable or impractical.

4. Frequently Asked Questions

Frequently Asked Questions

What is the rated energy capacity of the mobile system?

The battery system provides 522kWh of rated energy capacity with an operating voltage range of 728-949 VDC.

How much DC charging power is available?

The integrated charging system provides 320kW of rated output through two DC charging connectors rated at 160kW each.

What is the PCS power rating?

The integrated PCS is rated at 250kW. This is separate from the 320kW DC charging-system rating.

Can the system operate with renewable energy?

Yes. It can be integrated with solar PV and wind generation to store renewable energy, smooth output fluctuations, and supply on-site loads or charging equipment.

Where can the system be deployed?

Typical deployments include construction sites, fleet depots, remote operations, commercial facilities, emergency backup applications, renewable-energy sites, and locations that need temporary power or mobile charging.

How is battery temperature managed?

The battery compartment uses liquid cooling, while the electrical compartment uses air cooling. This dual-mode approach supports stable operation across changing loads and ambient conditions.

Is the system suitable for outdoor use?

The enclosure is rated IP54 and designed with C4 corrosion protection. Site conditions, local electrical codes, grounding, ventilation, and operating clearances must still be reviewed before deployment.
