Multi-Brand GSE Universal Charging Solution: How Door Energy Solves Equipment Compatibility Issues

As the global aviation industry accelerates its decarbonization goals, more and more airports are promoting the electrification of GSE (Ground Support Equipment). From electric towing vehicles and baggage trolleys to electric passenger stairs and aircraft towing vehicles, various types of equipment are gradually replacing traditional diesel-powered equipment.

However, in the process of electrification, a problem overlooked by many airport operators is gradually emerging: GSE equipment purchased from different brands, countries, and eras often uses different charging interfaces, communication protocols, and charging strategies.

This compatibility issue forces airports to build multiple charging systems, increasing investment costs and reducing operational efficiency.

It is against this backdrop that Door Energy's Mobile EV Charger is becoming a solution of increasing interest to airports, aviation service companies, and equipment operators.

It not only provides high-power mobile charging capabilities but, more importantly, achieves unified energy replenishment capabilities across brands, multiple devices, and multiple scenarios.

I. Compatibility Challenges Amidst the Global Electrification Wave of GSEs

According to statistics from the International Air Transport Association (IATA):

As the number of devices increases, compatibility issues begin to amplify rapidly.

A typical airport may simultaneously possess:

* Electric aircraft towing vehicles

* Electric shuttle buses

* Electric passenger boarding stairs

* Electric de-icing equipment

* Electric cargo loaders

* Electric baggage trolleys

* Electric ground power vehicles

These devices may come from different manufacturers.

The results are:

✓ Different interfaces

✓ Different voltage platforms

✓ Different BMS strategies

✓ Different charging standards

✓ Different communication methods

The operations team has to face complex energy management issues.

II. Why traditional fixed charging stations struggle to solve multi-brand GSE problems

Many airports initially opted to build fixed charging stations.

However, as the number of devices increased, their drawbacks gradually became apparent.

Low charging resource utilization

Fixed charging stations are typically built in parking areas.

The reality is:

* Passenger boarding stairs are scattered across the tarmac

* Baggage trolleys are constantly moving

* Aircraft towing vehicles are on standby

* The locations of special equipment are constantly changing

Equipment needs to actively search for charging stations.

This results in a large amount of inefficient movement.

High Costs of Redundant Construction

A medium-sized international airport with over 300 GSE devices typically requires the construction of:

The overall investment usually exceeds: US$1.5 million - US$5 million

And compatibility issues still exist.

Long New Device Integration Cycle

Each new device requires:

* Retesting

* Communication Verification

* Compatibility Check

* System Upgrade

This often takes weeks or even months.

Therefore, fixed infrastructure is increasingly struggling to adapt to the rapidly changing airport equipment ecosystem.

III. How Door Energy Mobile EV Charger Achieves Multi-Brand Compatibility

Door Energy's core concept is not to build more fixed charging facilities.

But rather, to achieve proactive energy delivery through a mobile integrated energy storage and charging platform.

Supports both CCS1 and CCS2 standards

For overseas markets:

CCS1

Mainly used in:

* USA

* Canada

* Mexico

CCS2

Mainly used in:

* Europe

* Australia

* Middle East

* Southeast Asia

Door Energy Mobile EV Charger is also compatible with:

Therefore, regardless of the country of origin of the device, unified charging management can be achieved.

OCPP Open Communication Protocol

Compatibility is not just an interface issue.

More importantly, it's about communication compatibility.

Door Energy supports: OCPP (Open Charge Point Protocol)

This is one of the most widely adopted charging communication standards globally.

Advantages include:

* Integration with existing energy management systems

* Integration with airport dispatch platforms

* Remote monitoring

* Data analytics support

* Future upgrade support

For large airports, this means integration can be achieved without overhauling the existing system.

IV. How High-Power Mobile Charging Improves Airport Operational Efficiency

Compatibility is only the first step.

Efficiency improvement is the real value.

Maximum 420kW DC Fast Charging

Door Energy Mobile EV Charger provides:

In many scenarios: Traditional equipment needs to return to the charging area.

Door Energy can go directly to the location of the equipment.

Energy follows the equipment.

Instead of the equipment searching for energy.

Reducing Equipment Downtime

Based on airport operation data from Europe and the US:

Some high-frequency operating equipment can reduce downtime by: 500-1200 hours per year

V. From Airports to Industrial Sites: One Platform Covering More Scenarios

Door Energy is not just for airports.

In fact, it was designed to meet energy needs in multiple scenarios.

Roadside Assistance Scenarios

The number of electric heavy-duty trucks is growing rapidly.

Based on industry forecasts:

After running out of power: The traditional solution is usually a tow truck.

Mobile EV Chargers can:

* Arrive on-site

* Quickly replenish power

* Restore driving capability

Avoid expensive towing fees.

Construction Site Scenarios

Construction sites are often far from the power grid.

Door Energy can provide AC power support for:

* Electric excavators

* Water pumps

* Lighting systems

* Temporary office areas

Compared to diesel generators:

Outdoor Industrial Scenarios

Including:

* Mining areas

* Ports

* Warehousing centers

* Railway stations

These areas often suffer from:

* Insufficient power grid

* Difficulty in temporary expansion

* Large fluctuations in power consumption

Door Energy mobile energy storage and charging systems can quickly fill energy gaps.

VI. How Modular Design Reduces Total Lifecycle Costs

Many users focus on the purchase price.

However, the greater cost actually comes from subsequent maintenance.

According to statistics on industrial equipment operation in Europe and America:

As you can see, maintenance costs are close to one-third of the total cost of ownership.

Door Energy Modular Architecture Advantages

Door Energy adopts a modular design.

Advantages include:

Faster Repair

Faulty modules can be quickly replaced.

No need for complete factory return.

Lower Maintenance Costs

Reduce labor input.

Higher Availability

Higher system continuity.

Easier Expansion

No need to replace the entire equipment when future demand increases.

For large airport fleets:

Every 1% increase in equipment availability can potentially bring hundreds of thousands of dollars in operational benefits.

VII. A Unified Energy Platform for the Future

Future airports will be more than just transportation hubs.

They will also be energy management centers.

According to ICAO forecasts:

By 2035:

Therefore, compatibility will become a crucial standard for energy infrastructure construction.

The Door Energy Mobile EV Charger achieves this through:

* CCS1 compatibility

* CCS2 compatibility

* OCPP protocol

* 420kW fast charging

* Mobile deployment capability

* Modular maintenance architecture

Helping airports, industrial enterprises, and roadside assistance service providers build a unified energy ecosystem.

Compared to single-brand solutions, it offers greater scalability; compared to fixed infrastructure, it is more flexible; compared to traditional charging methods, it significantly improves equipment utilization and operational efficiency.

As the global electrification process continues to accelerate, compatible, multi-scenario, and scalable mobile energy platforms will become a crucial infrastructure for future GSE (Gas-Electric Self-Service) operations. Door Energy is driving this transformation to accelerate its implementation.
