As more electric ground support equipment (eGSE) makes its way to the airside environment, the need for charging infrastructure is growing.
However, there are variations between charging equipment, the way eGSE units are charged and where charging infrastructure can be installed in an airport.
Ground Support Worldwide asked Jeffrey Rome, executive vice president at Motive Energy Sustainable Solutions about the various charging methods available to ground personnel in the aviation market.
Ground Support Worldwide: What type of batteries can use quick charging methods?
Jeffrey Rome: Both Lithium-ion and advanced lead-acid batteries can utilize quick charging methods. However, the suitability and safety of quick charging depend on the specific battery chemistry and design.
GSW: What eGSE applications require trickle charging?
JR: Trickle charging, or maintaining a battery at full charge by applying a small current, is often used for eGSE that experiences irregular use or long periods of inactivity, ensuring that the battery remains charged without overcharging.
GSW: What type of eGSE can utilize opportunity charging?
JR: Opportunity charging can be utilized by various types of eGSE, such as electric baggage tractors, forklifts and pushback tugs. This method is particularly beneficial for equipment used in multiple shifts throughout the day, allowing for battery top-ups during short breaks or downtime to extend operational availability.
GSW: What advantages does having an eGSE charger at the gate offer?
JR: Having an eGSE charger at the gate ensures that equipment is always ready for operation, minimizing downtime. It allows for opportunity charging of electric ground support equipment between flights, enhancing efficiency and reducing the need for spare equipment.
GSW: What are the main drawbacks?
JR: The main drawbacks of charging at the gate include potential congestion and space limitations at busy terminals, which can interfere with gate operations. Additionally, the installation and maintenance of charging infrastructure in these areas can be more costly and complex due to tighter security and operational restrictions.
GSW: What advantages does charging locations away from the gate offer?
JR: Charging away from the gate can reduce congestion and allow for more extensive charging infrastructure, accommodating more equipment simultaneously. It also offers flexibility in managing the charging schedule and maintenance without interfering with gate operations.
GSW: What disadvantages are associated with charging away from the gate?
JR: The primary disadvantage is the potential for increased downtime due to the need to transport equipment to and from charging locations, which may not be immediately adjacent to the gates. This can lead to logistical challenges and requires careful planning to ensure equipment is available when needed.
