The Best Batteries for Airport Ground Support Equipment: Choosing High-Performance GSE Electrification Solutions
As airports transition toward sustainability and electrification, choosing the right batteries for ground support equipment (GSE) is crucial. From tow tractors and shuttle buses to baggage conveyors and forklifts, electrification helps reduce carbon emissions, improve energy efficiency, and enhance operational performance. This guides explores key considerations for selecting airport GSE batteries, comparing battery types, voltage systems, and charging methods to meet the needs of modern airports.
Why Lithium Batteries Are the Best Choice for Airport GSE Electrification
Lithium-ion vs. Lead Acid Batteries
While lead-acid batteries have historically been used in airport vehicles like baggage tractors, the industry has largely shifted to lithium iron phosphate (LFP) batteries due to their superior performance. Here’s a comparison:

Lithium-ion vs. NCM Batteries: Why Safety Matters
Airports require the highest safety standards, making lithium iron phosphate (LFP) batteries are the optimal choice over nickel-cobalt-manganese (NCM) batteries.
Why LFP Batteries Are Safer?
- Thermal Stability: LFP batteries withstand temperatures up to 700-800°C before decomposition, compared to 200°C for NCM batteries, reducing fire risks.
- Proven Reliability: Widely used in electric buses, LFP batteries account for 98% of China’s electric bus market, demonstrating their safety and performance under demanding conditions.
While NCM batteries are favored for passenger cars due to their compact size and lightweight design, the safety and durability of LFP batteries make them better suited for electric ground support equipment.
Key Advantages of Lithium Batteries for Airport GSE
- High Energy Density: Delivers more power in a compact and lightweight degisn, optimizing vehicle performance.
- Longer Lifespan: Reduced replacement frequency translates to lower lifecycle costs.
- Superior Cold Weather Performance: Ideal for year-round operations, even in outdoor environments.
- Advanced BMS: Ensures safety, efficiency, and real-time monitoring.
High Voltage Systems: Optimizing Efficiency for GSE Batteries
When it comes to battery voltage, the choice between low-voltage (80V) and high-voltage (300V-600V) systems is critical.
Why High Voltage (300V-600V) is Superior?
- Higher Efficiency: High-voltage systems minimize energy loss and improve operational efficiency.
- Enhanced Safety: Lithium batteries, with advanced BMS, support higher voltages safely.
- Scalability: High-voltage configurations, such as the 576V, meet the power demands of larger GSE.
In constrast, lead-acid batteries are limited to 80V systems due to technical constraints, making them less efficient and impractical for modern GSE electrification needs.
Charging Solutions for Airport Electric GSE
Efficient charging is vital for electrified airport GSE. Here are the best practices for airport battery charging infrastructure:
- The optimal solution is distributed charging, conveniently located near parking spaces.
- Use standardized charging equipment (including charging voltage, protocols, and interfaces).
- Ensures “vehicles are compatible with all stations, and stations are compatible with all vehicles.”
- Distributed, near-parking charging is the best approach for airport electric ground support equipment due to the diverse range and unique designs of these vehicles. Battery-swapping is challenging and impractical for most airport GSE, making it unsuitable for this approach.
- Most airport GSE have limited range and are not designed for long-distance charging or swapping, making centralized charging facilities less ideal.
- Establishing 2-3 battery maintenance stations within the operational zone while receiving periodic battery inspections and maintenance. This is an excellent solution for maintaining battery health in newly constructed airports.
Choosing the Right Motor and Controller for GSE
Airport GSE should use permanent magnet brushless motors paired with multi-in-one motor controllers.
Advantages of This Setup:
- High Motor Efficiency: Permanent magnets enhance efficiency and reliability.
- Integrated Controllers: Combining multiple controllers (e.g., for drive, hydraulic, and air systems) into a single unit improves compactness, reduces wiring complexity, and enhances reliability.
- Rugged Design: Water-cooled, IP67-rated controllers withstand harsh operating environments while maintaining electromagnetic compatibility.
Conclusion: Powering the Future of Airport Operations
Electrifying airport GSE with high-performance electric batteries like LFP systems is essential for achieving sustanability goals. By choosing the right battery type, voltage system, and charging solutions, airports can reduce carbon emissions, lower operating costs, and enhance equipment reliability.
