Allye Energy Launches Battery-Buffered EV Charger Built From Repurposed Packs
The MEV charger can deliver up to 400 kW to two vehicles simultaneously from a standard 16-amp electrical connection.
Allye Energy has introduced the MEV, a battery-buffered EV charger constructed from repurposed electric vehicle battery packs, designed to enable high-power charging without requiring significant grid upgrades.
What Happened
The MEV charger features built-in battery storage made from whole repurposed EV packs. It is available in two variants: the MEV200, which offers 155 kWh of energy storage and up to 200 kW of charging power, and the MEV300, which provides 232 kWh of storage and 300 kW of power. Both units can charge two vehicles simultaneously and operate on electrical supplies ranging from a 16-amp single-phase connection to a 125-amp three-phase connection. The charger utilizes an 800 V architecture to maximize efficiency and serve both 400 V and 800 V vehicles.
Allye’s proprietary PackFlex technology allows each battery pack to have independent battery management and power control, enabling packs of different sizes, ages, and chemistries to function together in a single cabinet. The MEV units are engineered and built in the UK, using batteries from UK-registered vehicles and 95% British-sourced components. According to the company, reusing these EV battery packs avoids an estimated 15 to 24 tons of CO2 per MEV unit compared to using new cells.
Why It Matters
Battery-buffered chargers like the MEV allow fleet operators and charging providers to deploy high-power DC charging infrastructure without the cost and time associated with utility grid upgrades. By storing energy when demand is low and releasing it during peak charging sessions, these systems help avoid high utility demand charges. This approach is particularly relevant for depots with limited electrical capacity, such as the Roadchef site on the M6, which has operated a MAX300 system on a fixed 315 A supply shared with other businesses for over two years.
The launch of the MEV complements Allye’s existing MAX300 product, a portable battery energy storage system and charger mounted on a trailer. While the MAX300 is designed for mobility or adding capacity to stationary sites, the MEV is intended for fixed installations where the primary function is charging vehicles. Allye founder and CEO Jonathan Carrier stated that the MEV is often more cost-effective than the grid connection works it replaces. The company reports that more than 20 MAX systems, built from over 100 repurposed batteries, are currently in service with customers including JLR and Roadchef.
The Bottom Line
Deliveries for the Allye MEV charger are expected to begin in the second quarter of 2027, aligning with Round 2 of the UK government’s Depot Charging Scheme. The company also offers charging-as-a-service, handling site surveys through to commissioning.
