As airports worldwide continue to advance green and low-carbon development, an increasing number of Ground Support Equipment (GSE) systems are adopting electrification. From aircraft tow trucks and baggage trolleys to maintenance and inspection vehicles, electric equipment has become an essential component of modern airports.
However, growing alongside vehicle electrification are increasingly complex energy supply needs.
Airports have multiple operational areas, including aprons, terminals, cargo areas, and maintenance areas. Vehicle movement is frequent, and tasks change rapidly. Relying solely on fixed charging facilities is insufficient to meet the demands of all-weather, multi-area, and high-efficiency operations.
How to make energy flow as flexibly as vehicles has become a crucial issue in the construction of smart airports.
Door Energy's Mobile EV Charger, through mobile energy storage, high-power DC fast charging, intelligent communication, and modular design, provides airports with a comprehensive mobile energy solution covering all scenarios, making energy supply more efficient, flexible, and secure.
I. Why Does Airport Operation Require Comprehensive Energy Supply?
The Number of Electric GSEs Continues to Grow
In recent years, more and more airports worldwide have accelerated the phasing out of traditional fuel-powered equipment.
Increasingly common electric equipment includes:
* Electric aircraft towing vehicles
* Electric baggage handling vehicles
* Electric passenger boarding stairs
* Electric maintenance vehicles
* Electric inspection vehicles
* Electric service vehicles
As the number of vehicles increases, energy demand also expands.
Wide Operating Areas and Frequent Vehicle Movement
Airports are not fixed factories.
Different vehicles need to travel daily between:
* Apron
* Terminal
* Maintenance area
* Cargo area
* Temporary support area
Vehicles rarely remain in the same location for extended periods.
Therefore, energy supply needs to be more flexible.
24/7 Operations Require Continuous Recharge
Airports typically operate 24 hours a day.
Especially at:
* International airports
* Large hub airports
Cargo airports
Vehicles need to be readily available for support tasks.
Energy supply must remain stable and reliable.
II. Why is a Fixed Charging Model Inadequate to Cover All Needs?
Limited Coverage
Fixed charging facilities can only serve nearby areas.
When vehicles are far from charging points:
Additional time is needed to return for recharging.
This not only increases operating costs but may also affect task scheduling.
Long Construction Cycle
Adding new fixed charging facilities typically involves:
* Grid expansion
* Cable laying
* Civil construction
* Power distribution system upgrade
The entire construction process takes a considerable amount of time.
For rapidly developing airports, this lacks flexibility.
Inability to Quickly Respond to Temporary Needs
Airports experience daily operational changes.
For example:
* Temporary flight additions
* Charter flight support
* Extreme weather
* Emergency drills
Fixed facilities cannot be quickly adjusted and deployed.
III. How Does Door Energy Achieve Full-Scenario Energy Coverage at Airports?
Energy Actively Reaches the Device
Traditional Model: Vehicles search for charging facilities.
Door Energy Mobile EV Charger: Energy actively travels to the vehicle's location.
This changes the traditional way airports recharge.
Covering Multiple Airport Areas
A single device can be deployed to:
* Apron
* Terminal
* Aircraft Maintenance Area
* Baggage Handling Center
* Cargo Warehouse
* Temporary Construction Area
Achieving true mobile power replenishment.
Meeting the Needs of Different Operational Phases
Whether it's:
* Daily Power Replenishment
* Peak Operations
* Nighttime Support
* Emergency Missions
Door Energy can be quickly deployed.
IV. How Does High-Power Mobile Power Storage Improve Airport Operational Efficiency?
Up to 420kW DC Fast Charging
Door Energy supports up to 420kW DC fast charging.
High power output means:
* Shorter Power Replenishment Time
* Faster Recovery
* Higher Equipment Utilization
For airport vehicles that need to operate continuously, rapid power replenishment can effectively reduce waiting time.

Improving the Continuous Operation Capability of Critical Equipment
For airports: Vehicle downtime not only affects the equipment itself, but may also affect:
* Aircraft turnaround efficiency
* Baggage handling efficiency
* Ground handling service quality
Door Energy mobile power supply can help equipment quickly return to working status.
V. Multi-Scenario Applications Enable Mobile Power Supply to Play a Greater Role
Apron Support
Aircraft support vehicles are usually distributed across different aircraft stands.
Mobile power supply can go directly to the work site.
Reducing vehicle travel time.
Maintenance Area Support
During maintenance vehicles and equipment testing: temporary power support may be required.
Door Energy provides rapid power replenishment.
Cargo Area Power Replenishment
Cargo airport vehicles operate frequently.
Door Energy mobile storage and charging can help:
* Baggage transport vehicles
* Cargo handling vehicles
* Electric forklifts
Quickly replenish power.
