Bridging the Gap in High Voltage GSE
As major airports worldwide pivot toward electrification, the shift from low voltage to High Voltage GSE equipment emerges, leaving airports facing a difficult choice: overhaul their entire electrical infrastructure or limit their fleet's growth.

The Infrastructure Challenge
Most major airports operate on an existing 150V DC bus: a reliable, established infrastructure designed for traditional GSE needs. However, as High Voltage GSE equipment emerges, the demand has outpaced standard grids.
01. Infrastructure Rigidness
Airports cannot easily or affordably replace the 150V DC bus systems that span across miles of tarmac and terminals.
02. Fleet Fragmentation
Airline ground operations are managing a "mixed fleet" of low and high voltage chargers, often requiring entirely separate power sources for each.
03. Upgrade Costs
Waiting for new transformers or trenching for high-voltage lines can take years and cost millions in capital and opportunity costs.
Pii’s DC-to-DC Charging Innovation
Averest partnered with Pii to solve this dilemma. Instead of requiring a new AC grid connection, Pii provided its advanced charger line to interface directly with the airport’s existing 150V DC bus.
DC Bus Integration
Pii chargers are engineered to "tap into" the existing 150V DC infrastructure, converting that power to the specific needs of high-voltage GSE.
Mixed-Voltage Flexibility
This approach allows Averest to deploy low voltage and high voltage chargers on the same infrastructure, side-by-side.
Input-Agnostic Conversion
Similar to Pii’s success with municipal electric fire trucks, these units handle varying input conditions without requiring grid-level hardware changes.
Seamless Scalability
By leveraging the current bus, Averest can scale their high-voltage GSE services immediately, bypassing the typical 24-month wait for utility transformer upgrades.
Featured Success Story
By installing Pii’s flexible EV charging technology, Averest has successfully expanded its service offerings to include high-voltage without the need for a single foot of new electrical trenching. This partnership demonstrates the viability of a path to zero-emission airports without extensive infrastructural upgrades.
"Pii enabled us to bridge the gap between legacy airport infrastructure and the next generation of high-voltage equipment. We can now offer a versatile, mixed-voltage charging environment using the same DC bus we've relied on for years."
