Mobile electric vehicle charging provider SparkCharge has partnered with Zipcar and the Massachusetts Clean Energy Center (MassCEC) to deploy a high-power, off-grid fast-charging hub at Zipcar’s East Boston maintenance facility, supporting electric fleet charging without the need for traditional utility infrastructure upgrades.
The charging hub, backed by funding from MassCEC’s InnovateMass program, delivers up to 320 kilowatts of DC fast charging using a battery-powered mobile trailer system. The installation is designed to serve Zipcar’s growing shared electric vehicle fleet and accelerate turnaround times for vehicles operating across Greater Boston.
The system operates independently of fixed grid construction timelines by relying on onboard battery storage that is replenished using supplemental power from the facility. This allows high-speed charging without overloading local electrical infrastructure, offering what the project partners describe as a rapid-deployment model suited to dense urban areas.
“This project shows how fleets can scale electrification without waiting years for utility upgrades,” said Joshua Aviv, chief executive of SparkCharge. “We’re helping remove the traditional infrastructure barriers that slow EV adoption in communities that need fast, reliable access to clean transportation.”

The project is being rolled out in East Boston, an area classified as an Environmental Justice community, with the aim of expanding equitable access to electric mobility. MassCEC said the initiative reflects the state’s broader strategy to meet its net-zero emissions target by 2050 while ensuring the benefits of electrification extend to underserved neighborhoods.
Zipcar said the new charging hub integrates directly into its vehicle maintenance workflow, allowing faster preparation of electric vehicles for customer use. The company said the system supports both member rentals and ride-hailing drivers who depend on fast vehicle availability.
