IP54 1044 KWh Mobile Battery Storage Systems BESS With 800 KW Four Gun DC Charging

Product Overview

Create a deployable charging hub for demanding fleet and construction operations. The 1044 kWh mobile BESS integrates four 200 kW DC charging guns and a 500 kW AC PCS, pairing a 1.044 MWh energy reserve with multiple vehicle connections and higher-power AC supply capability.

YINTU is an energy storage solution provider. We work with capable manufacturing partners to match mobile equipment, charging interfaces and site requirements, and coordinate technical clarification and the agreed project supply scope.

Key Features

4 charging guns with 800 kW total DC rating

The integrated charger provides 4 x 200 kW rated charging outlets across a stated 200-1000 V DC output range. Select compatible connectors and communication protocols for the intended vehicles. Actual charging power follows vehicle voltage, current limits, battery state and operating conditions.

500 kW AC power capability

The integrated PCS provides a 500 kW AC rating at 230/400 V and 50/60 Hz. It supports energy conversion and selected AC supply duties alongside the dedicated DC charging system. AC PCS and DC charging ratings describe separate functions and must not be added together as a guaranteed simultaneous output.

Integrated storage, charging and control

LiFePO4 batteries, BMS, PCS, charger and EMS are combined in one mobile equipment platform. BMS and EMS coordination supports operating supervision while the project design defines energy reserve, load priorities and permitted power allocation.

Thermal management and outdoor protection

Liquid cooling manages the battery compartment and air cooling serves the electrical compartment. IP54 protection, C4 corrosion grade and aerosol fire protection provide a defined equipment specification for outdoor site selection and operating planning.

Applications and Project Value

Heavy-duty fleet charging

Deploy four 200 kW DC charging outlets at a temporary truck depot or logistics facility. The 1044 kWh battery provides a larger energy reserve for coordinated sessions involving compatible heavy vehicles, with charger allocation and vehicle acceptance limits included in the operating plan.

Large construction sites

Bring 1.044 MWh of stored energy close to excavators, bulldozers and loaders. Multiple charging outlets can serve a changing group of compatible machines while the mobile system is placed near the active work front rather than a distant fixed charging station.

Road and pavement machinery

Support compatible graders, road rollers and asphalt pavers across project areas. A planned charging window and reserve policy help align energy availability with the work schedule, while transport access and safe placement are assessed before moving the equipment.

Lifting and site logistics

Supply charging access for compatible cranes, truck cranes and transport vehicles during site operations. Four outlets give the project team more connection points to schedule, without assuming every vehicle will accept the rated gun power throughout a session.

Higher-power AC backup

Use the 500 kW PCS for selected industrial, commercial or temporary-work loads. Grid-connected and islanding specifications support an engineered backup arrangement with load prioritisation, protection and suitable source-transfer equipment.

Temporary fleet hubs

Establish a mobile charging hub where installed charging capacity is unavailable or insufficient. The platform can be assigned to a particular depot, campaign or project period, with recharge access and the required daily energy throughput planned before deployment.

How the Mobile System Works

A compatible grid connection allows the PCS to charge the battery under the approved operating arrangement. Stored DC energy serves the integrated DC charger for compatible vehicles or passes through the PCS to supply selected AC loads. EMS and BMS coordination manages the system within its configured limits.

For a planned AC backup installation, the source selection, STS and protection arrangement coordinates grid supply, any standby source and the PCS. The datasheet specifies a grid-to-off-grid STS switching time below 10 ms; the final project design determines which loads and transfer functions are included.

Battery, PCS and DC Charging Specifications

The stated cell cycle life is not a system service-life or warranty guarantee. Charging power varies across the output-voltage range and is limited by the connected vehicle, current rating and operating conditions.

System and Installation Parameters

Dimensions and weight are equipment values. Trailer or chassis supply, payload, axle loading, road approvals and the final transport arrangement are confirmed for the selected configuration and destination.

Frequently Asked Questions

What does the kW figure in the model refer to?

This model has 800 kW total rated DC charging power, provided through 4 x 200 kW charging guns. The AC PCS rating is 500 kW. These ratings are separate and do not establish a combined simultaneous output.

Which vehicles can be charged?

Compatible electric passenger, commercial or construction vehicles may be considered after checking connector type, communication protocol and voltage/current limits. No universal connector standard is specified in this datasheet.

How long can the system operate?

The nominal battery energy is 1044 kWh. Practical charging throughput and AC runtime depend on usable battery limits, reserve, conversion and auxiliary losses, temperature and the actual vehicle or load demand.

Can it supply AC loads without the grid?

The datasheet includes off-grid PCS ratings and STS transfer performance. The supported loads, reserve, earthing, isolation and switching arrangement are established in the project design.

Is the illustrated trailer included?

The product image shows a mobile configuration. Equipment dimensions and weight are stated separately; trailer/chassis scope and the final transport configuration are confirmed in the quotation.
