SparkCharge has partnered with the Massachusetts Clean Energy Center (MassCEC) and Zipcar to launch the Northeast’s first off‑grid, mobile DC fast‑charging hub for shared EVs. The goal is to bring fast, reliable EV charging infrastructure into communities without having to wait for costly or slow grid upgrades.
The hub sits at Zipcar’s maintenance facility in East Boston, an Environmental Justice community. It’s funded through MassCEC’s InnovateMass program and gives onsite mechanics the ability to quickly recharge a rotating fleet of Zipcar EVs before they’re dispatched across Greater Boston. Members and rideshare drivers who rent Zipcars will get steadier access to charged EVs.
“Electrification should never be limited by where the grid is or how long it takes,” SparkCharge founder and CEO Joshua Aviv said. “With this program in East Boston, we’re showing how fleets can deploy at scale, in any community, and deliver clean mobility today.”
At the center of the setup is SparkCharge’s Mobile Battery‑Powered Trailer, which delivers 320 kW of DC fast charging without the delays and big price tags that usually come with fixed infrastructure. The trailer can recharge from Zipcar’s existing onsite power between sessions, topping up its high‑capacity batteries without stressing the local grid. Since it avoids major grid upgrades entirely, the model is designed to deploy quickly and at zero upfront cost for fleets.
MassCEC says the project shows what community‑first fast charging can look like. “Every resident deserves access to clean, reliable transportation,” said Leslie Nash, MassCEC’s senior director of Technology‑to‑Market. “By partnering with SparkCharge and Zipcar in East Boston, we’re showing how Massachusetts is leading the way in clean transportation innovation.”
The hub also plays into Massachusetts’ push to hit its net‑zero 2050 targets. As shared mobility grows, electrifying fleets will be key to cutting emissions in dense urban corridors. This project introduces a scalable charging option to a part of Boston that is underserved by public charging, helping to keep Zipcar’s EVs reliably on the road.
“For twenty‑five years, Zipcar has been a leader in shared mobility, and we’re proud to take another step toward a more sustainable future,” said Angelo Adams, Zipcar’s president. “Working with SparkCharge and MassCEC allows us to bring fast, reliable EV charging directly to our members and rideshare drivers.”
Zipcar, which is owned by car rental company Avis Budget, announced on December 1 that it was shutting down its UK operations by December 31, 2025. An Avis Budget spokesperson stated that the reason was “to streamline operations, improve returns, and position the company for long-term sustainability and growth,” adding that “all other markets remain unaffected.”
