Trailer Mounted 261 KWh Mobile BESS Liquid Cooled With 160 KW Dual Gun DC

Product Overview

Bring stored energy closer to the job with a compact mobile BESS and charging station. The 261 kWh platform combines two 80 kW DC charging guns with a 250 kW AC PCS, giving contractors and service operators a practical choice of vehicle charging or temporary AC supply from one equipment package.

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

2 charging guns with 160 kW total DC rating

The integrated charger provides 2 x 80 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.

250 kW AC power capability

The integrated PCS provides a 250 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

Mobile charging service

Dispatch the system to a temporary vehicle stop, service area or worksite where a fixed charger is unavailable. Two 80 kW charging guns provide defined outlets for compatible vehicles; the deployment schedule accounts for vehicle arrival times and the available battery reserve.

Compact construction sites

Bring charging to compatible electric loaders and excavators near the active work area. Moving the energy source with the work front can reduce the need to return equipment to a distant charging point. Select connector standards and operating clearances for the machinery involved.

Municipal fleet support

Supplement charging for compatible sanitation and transport vehicles at temporary stops or satellite depots. The 261 kWh reserve can be allocated to selected vehicles and daily service priorities while the main depot charging network is expanded or unavailable.

Road and lifting equipment

Position the mobile system at a planned staging point for compatible road machinery or lifting equipment. Site planners can coordinate charging breaks with machine duty cycles, keeping the charging location flexible as the project progresses.

Emergency and maintenance AC supply

The 250 kW PCS can support selected AC loads at facilities during a supply interruption or planned maintenance. Define the load priorities, reserve target and transfer arrangement in advance so the equipment is ready for deployment.

Temporary work areas

Use one integrated storage and conversion package for short-term site power and vehicle charging requirements. The approximately 3.5 t equipment weight and stated equipment dimensions help the project team assess handling, placement and transport requirements.

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 160 kW total rated DC charging power, provided through 2 x 80 kW charging guns. The AC PCS rating is 250 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 261 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.
