Mobile EV Charging Solutions for 500–700 kWh Electric Construction Equipment: CCS2 and CEE Input Requirements

Published by XIAOFU POWER | Mobile Energy Storage & EV Charging Solutions

As heavy construction equipment transitions from diesel power to electric operation, charging infrastructure is becoming a critical challenge for construction contractors, equipment rental companies, mining operators, and fleet managers.

Electric dump trucks, heavy-duty tipper trucks, wheel loaders, and other construction machinery increasingly require battery capacities of 500–700 kWh or more.

However, many construction sites do not have sufficient grid capacity to support high-power DC charging. Temporary job sites, remote construction areas, and off-grid operations create additional challenges.

A mobile EV charging solution equipped with a CCS2 connector and industrial CEE AC input can provide a flexible approach to charging heavy electric machinery.

In this article, XIAOFU POWER explains the key technical requirements, charging configurations, and application scenarios for mobile charging solutions designed for large-capacity electric construction equipment.

1. Why Do 500–700 kWh Electric Construction Machines Need Mobile Charging?

Heavy electric construction machinery has different charging requirements from passenger electric vehicles.

For example:

Electric dump trucks operating on large construction sites.
Battery-powered tipper trucks transporting soil, gravel, and aggregates.
Electric wheel loaders working in quarries and mining operations.
Heavy-duty construction vehicles operating in remote locations.
Electric machinery used in infrastructure and road construction projects.

These machines typically have large battery packs, high daily energy consumption, and demanding operating schedules.

Three major challenges affect their charging operations.

Limited grid capacity

Many temporary construction sites cannot provide sufficient electrical power for high-speed DC charging.

Unstable or unavailable charging infrastructure

Construction equipment frequently moves between working areas, making fixed charging stations less practical.

Operational downtime

Long charging periods can reduce equipment utilization and increase operating costs.

A mobile battery energy storage system integrated with DC fast charging can help address these challenges by bringing charging power directly to the equipment.

2. Key Technical Requirements for a Heavy-Duty Mobile EV Charger

Based on current customer requirements for charging electric construction machinery with 500–700 kWh battery capacity, the following specifications are important.

Technical requirement	Customer specification
Application	Heavy construction equipment
Target battery capacity	500–700 kWh
DC charging connector	CCS2
AC input connector	Industrial CEE
AC input current options	32A / 63A / 125A
Charging solution	Mobile DC fast charging
Installation environment	Construction sites and outdoor operations

The final charger power, energy storage capacity, charging voltage range, and charging duration should be determined according to the vehicle’s battery specifications and daily energy consumption.

CCS2 DC Charging Compatibility

CCS2 (Combined Charging System Type 2) is widely used in European commercial electric vehicles and electric machinery.

For heavy construction equipment, CCS2 compatibility is an important consideration when selecting a mobile DC charging system.

The charging solution should be evaluated for:

CCS2 connector and communication compatibility.
DC output voltage matching the vehicle battery.
Maximum charging current and power.
Vehicle Battery Management System (BMS) communication.
Charging protection and safety monitoring.
Cable length and outdoor operating conditions.

For 500–700 kWh electric machinery, selecting the correct DC output power is particularly important.

The charger must match the vehicle’s actual charging limits rather than relying solely on battery capacity.

Industrial CEE AC Input: 32A, 63A or 125A

Another important requirement is the AC input connection.

Industrial CEE connectors are commonly used in temporary power distribution systems, industrial facilities, and construction environments.

The requested input options include:

32A CEE Input

Suitable for locations with relatively limited electrical supply capacity.

63A CEE Input

Provides greater input capacity for charging the mobile energy storage system.

125A CEE Input

Designed for applications where higher AC input capacity is available.

These input options provide flexibility when connecting the mobile charging system to different industrial power sources.

The actual charging power depends on the input voltage, number of phases, power factor, and system configuration.

XIAOFU POWER can evaluate different AC input configurations according to project requirements.

3. How Does a Mobile Battery Energy Storage Charging System Work?

A mobile energy storage charging system combines battery storage, power conversion, and DC charging technology into one integrated solution.

A typical operating process is:

Step 1: Connect to an Available Power Source

Connect the mobile charging system to an available industrial AC power supply through the appropriate CEE connection.

Step 2: Store Electrical Energy

The integrated battery energy storage system stores electricity for subsequent charging operations.

Step 3: Charge Electric Construction Machinery

Connect the CCS2 DC charging cable to the electric dump truck, tipper truck, or other compatible construction equipment.

Step 4: Deliver DC Fast Charging Power

The system supplies DC power according to the vehicle’s permitted voltage, current, and charging requirements.

Step 5: Move the Charging Solution When Needed

Depending on the system design, the mobile charging unit can be relocated to different working areas or construction sites.

This configuration can reduce dependence on high-capacity grid connections and provide greater flexibility for temporary operations.

4. Typical Applications of Mobile EV Charging for Heavy Construction Equipment

Electric Dump Trucks and Tipper Trucks

Electric dump trucks are increasingly being adopted for material transportation in construction, mining, and quarry operations.

A mobile CCS2 charging system can provide charging support at designated operating locations without requiring a permanent high-power charging installation at every site.

Electric Wheel Loaders and Excavators

Electrified wheel loaders and excavators require reliable charging infrastructure to maintain productivity.

Mobile charging equipment can be positioned near machinery operating areas, reducing unnecessary vehicle movement to distant charging stations.

Remote Construction and Infrastructure Projects

Road construction, bridge development, and large infrastructure projects often involve temporary working environments.

A mobile energy storage charging system can provide an alternative where permanent charging infrastructure is unavailable or delayed.

Mining and Quarry Operations

Mining and quarry sites may have limited electrical infrastructure and demanding equipment utilization schedules.

Battery-integrated mobile DC charging solutions can support flexible energy distribution across designated operating areas.

5. How to Select the Right Mobile Charger for a 500–700 kWh Electric Machine?

Battery capacity alone does not determine the required charger configuration.

Before selecting a mobile EV charging system, project operators should evaluate the following parameters.

Selection factor	Information required
Vehicle battery capacity	500–700 kWh
Charging connector	CCS2
Battery voltage	Actual vehicle operating voltage
Maximum DC charging power	Vehicle-supported charging power
AC input	CEE 32A / 63A / 125A
Available power supply	Voltage, phase and current
Desired charging duration	Target charging time
Operating environment	Construction site, quarry or mining area
Mobility requirements	Trailer-mounted, skid-mounted or other configuration

For example, a machine with a 600 kWh battery may require a substantially different charging configuration depending on whether the operator wants to recharge from 20% to 80% within two hours or perform slower charging during scheduled downtime.

Therefore, engineering evaluation is essential before confirming the final configuration.
