Allye Energy has launched Allye MEV (MAX for EV), an electric vehicle charging system with built-in battery storage made from repurposed electric vehicle battery packs.

MEV charges its internal batteries using the power supply already available at the depot, then delivers up to 400kW of charging power to two vehicles simultaneously. The system can provide this output even when connected to a 16A supply, without the grip upgrade typically required for fleet electrification, according to a company press release.

MEV is available in two configurations: the MEV200 with 155kWh of energy storage, and MEV300, with 232 kWh. Both use repurposed EV battery packs.

Reusing the battery packs avoids an estimated 15 to 24 metric tons of greenhouse gas emissions, measured in carbon dioxide equivalent, per unit compared with using new battery cells, the press release states.

Allye’s PackFlex technology provides independent battery management and power control for each pack, allowing batteries of different sizes, ages and chemistries to operate together in the same enclosure.

The charger features an 800-volt electrical system designed to deliver power efficiently and support vehicles with either 400-volt or 800-volt battery systems. Its energy storage capacity and charging power can also be increased on site with minimal disruption and without additional excavation or foundation work.

MEV can be operational within hours of arriving at a site. It connects through existing industrial sockets or can be hard-wired and is designed to fit within permitted development requirements. Allye manages the process from site survey through commissioning. The system can also be removed or relocated if a depot moves or a lease ends, according to the press release.

 The system includes several safety and security features.  Intelligent lighting illuminates the charging area when someone approaches, while cameras installed on the charging bays and cables begin recording upon approach. To deter cable theft, each cable includes cut detection, forensic marking and quick-release terminals for replacement.

Each battery pack also features a pyro fuse to isolate its high-voltage circuits, along with off-gas detection and fire barriers between packs. Fire suppression systems are available for critical sites.

MEV builds on the architecture of Allye’s MAX300 mobile energy storage system, but is designed specifically for depot-based fleet charging. While MAX300 can provide mobile or stationary power, replace diesel generators and support vehicle charging through integrated DC fast charging or satellite chargers, MEV is designed to remain at a depot and charge vehicles where they are parked using the site's existing power supply.
