Used EV packs energize Allye’s new EV fleet charger

U.K. renewable energy vendor Allye Energy has unveiled what it claims is the world’s first dedicated electric vehicle (EV) charger with built-in battery storage made from repurposed EV packs.
Called the Allye MEV, the system delivers up to 400 kilowatts to two vehicles at once, even from a 16-amp connection. About 95% of the components in the charger are British-sourced, the company said.
The MEV initially will have two variants, both using repurposed battery packs. The MEV200 is a 155-kilowatt- hour (kWh) charging unit while the MEV300 is a 232-kWh charging unit. Reusing the EV packs avoids an estimated 15 to 24 tons of carbon dioxide equivalent (CO2e) per MEV compared with new cells.
The PackFlex technology inside the EV chargers integrates independent battery management and power control with an 800-volt architecture to serve both 400 V and 800 V vehicles.
The MEV can charge vehicles within a few hours of arriving at a fleet site and can be connected via industrial sockets or hard-wired. The MEV is built on the engineering of the MAX300, Allye’s mobile battery storage system that also uses repurposed EV packs.
Robert Carter, CTO at Allye Energy, said the hard part of developing the MEV was never the battery. “It was making packs of different sizes and ages behave as one system and deliver up to 400kW of DC charging through an 800V architecture and our in-house technology stack,” Carter said. “Once we had solved that, MEV was the obvious next step: the same architecture in a cabinet that only ever charges, where one pack can slide out for service while the others keep charging.”
Why battery storage is needed for fleets
According to Allye Energy, grid capacity is the largest barrier to electrification of fleets in the U.K. The company points to data from freight infrastructure organization TwentyForty, which said it takes about 18 to 36 months for a new depot connection in the U.K., and some businesses could wait up to 15 years before receiving electric infrastructure.
The company said these depots are not short on energy but short on the power to deliver it quickly — with some fleets waiting for hours to charge between shifts.
Allye Energy said its battery solution can power satellite DC fast chargers that support two EVs and supply about 200 kWh a day. The MEV turns that approach into a dedicated, fixed charger.
