Move Energy Instead of Waiting for Infrastructure
Grid capacity is not always available where vehicles and equipment need power. The Ruisu Mobile BESS brings stored energy to construction sites, fleet depots, events, emergency operations, and temporary service locations. It can support compatible AC loads, provide DC fast charging, or operate as a mobile energy buffer within an engineered power system.
By integrating battery storage, power conversion, and EV charging in one relocatable platform, the system helps operators add temporary capacity without installing permanent charging infrastructure first.
One Mobile Platform, Three Operational Roles
Mobile EV Charging
Two CCS2 charging guns deliver up to 160kW of total rated charging output, with 80kW available per gun. The 200–1000V DC output range supports a broad range of compatible commercial and passenger electric vehicles.
Temporary AC Site Power
The integrated PCS provides 125kW of rated AC power at 230/400V and 50/60Hz. Powerlock and CEE connections provide practical interfaces for compatible temporary facilities, industrial equipment, and site distribution systems.
Mobile Energy Buffer
The 261kWh battery stores energy when a compatible grid or generation source is available and releases it closer to the point of demand. This capability helps project teams manage temporary capacity constraints and reduce reliance on continuously running combustion generators.

Energy inputs, Ruisu Mobile BESS, energy outputs, and remote energy management.
Designed for Field Deployment
Liquid-Cooled Battery Thermal Management
Liquid cooling supports controlled battery temperatures across changing power levels and ambient conditions. The auxiliary equipment uses forced-air cooling as part of the integrated thermal-management design.
Outdoor-Ready Protection
The enclosure is specified to IP54 with a C4 anti-corrosion grade for demanding commercial and industrial environments. The specified operating temperature range is -30°C to 50°C.
Accessible Internal Layout
An organized battery compartment and clearly arranged AC and DC interfaces support inspection, connection, and service access during repeat deployments.
Integrated Safety Architecture
The system includes battery monitoring, high-voltage protection, and an aerosol fire-protection system. Final transport, installation, operation, and emergency procedures must follow the approved technical documentation and applicable local requirements.

Applications
Temporary Fleet Charging
Add charging capacity at depots, overflow parking areas, vehicle demonstrations, and temporary logistics bases before permanent infrastructure is available.
Construction and Infrastructure Projects
Move stored energy and compatible AC power between changing work areas where grid access is limited or still under development.
Mobile Charging Services
Deliver scheduled or responsive charging at customer sites, service locations, and roadside-support operations.
Events and Temporary Facilities
Provide battery-based power close to compatible loads where noise, local emissions, and cable distance are important project considerations.
Grid-Constrained Sites and Microgrids
Use the system as a mobile energy buffer within an engineered microgrid or temporary power system, subject to project-specific controls and protection coordination.
Frequently Asked Questions
What is a 261kWh 160kW Mobile BESS?
It is a relocatable battery energy storage and charging system that stores 261kWh of energy, provides 125kW of rated AC power, and delivers up to 160kW of total DC charging through two CCS2 charging guns.
Can the system charge two electric vehicles at the same time?
Yes. The system includes two CCS2 charging guns rated at 80kW each. Actual charging power depends on vehicle limits, battery state of charge, temperature, and system settings.
How long can the battery power a load?
Runtime depends on usable energy, average load, conversion losses, reserve state of charge, and ambient conditions. For project sizing, provide the expected load profile and required operating time to Ruisu.
Is the system suitable for outdoor use?
The enclosure is specified to IP54 with a C4 anti-corrosion grade and an operating temperature range of -30°C to 50°C. Final suitability depends on the site assessment, installation plan, and applicable local requirements.
What information is required for a quotation?
Provide the country of use, application, load or vehicle type, required AC and DC power, daily energy demand, ambient temperature, connector standard, mobility requirements, and available charging source.
