Your fleet is ready to go electric. Your grid connection isn't.
Charge your fleet. Skip the grid upgrade.
Rapid charging from the supply you already have: MEV where your fleet parks, MAX anywhere, up to 1.28MW.
The problem
The grid is the bottleneck, not the vehicles
Fleets need a lot of power for a few hours. Grid upgrades are sized, priced and timed for neither.
On and off-grid Depots, hubs, vans, trucks and buses
Years to wait
New connections take 1 to 3 years, and up to 15 for some fleets.
Costly upgrades
UK site upgrades cost £150k to £3m, averaging around £500,000.
Short, sharp peaks
Vehicles charge in tight windows, so high power is needed briefly.
Diesel stopgaps
Generators bridge the gap at a cost, and undo the point of going EV.
How it works
A buffer between the grid and your vehicles
MAX stores energy slowly from a small supply and delivers it fast to vehicles.
Store
Charge steadily from three- or single-phase supplies, from 16A.
Charge
Two DC outlets deliver 60kW to 1.28MW, plus AC, to any vehicle.
Move
Redeploy as depots change, with no pad, fencing or groundworks.
Three ways to charge
A dedicated charger at the depot, a buffer for your chargers, or charging anywhere.
Charges your fleet where it parks
MEV is a battery-buffered rapid charger that stays put at the depot. It recharges from the supply you already have and delivers up to 300kW of DC charging.
Powers anything, anywhere
MAX stays in one place to buffer your chargers, or moves with the work to charge where there is no grid. Four systems from 328kWh to 1.5MWh, with up to 1.28MW of integrated DC charging.
Buffer your chargers
MAX charges from a small supply and runs new or existing chargers at full speed.
J&M Murdoch: DC fast charging from 32A. £300k grid upgrade deferred, live in a day.
Charge standalone
Chargers built into MAX, recharged from a DC charger, another MAX or a generator.
Lower Thames Crossing: four MAX500s charge excavators, no grid. Over £30k a week saved.
Each DC charger has two outlets. The power quoted is the total, shared when two vehicles plug in.

Charging
From cars and vans to 44‑tonne trucks
DC charging from 60kW to 1.28MW, with two outlets so two vehicles charge at once.
Specify your preferred brand of charger, and we do the integration.
Why Allye
Made for depots
An option for every site
Small or large, fixed or mobile: MEV at the depot, MAX for site power and charging wherever the work is.
Running in hours
Delivered tested and ready: charging within hours of arrival. Add units as your fleet grows.
Software that learns your site
Machine learning predicts load and AI schedules every half hour of charging and discharging.
Open to the markets
Open API for third-party optimisers, so MAX and MEV earn from grid flexibility and wholesale prices.
Lower-carbon hardware
Built in Britain from EV batteries already on our roads: 60% lower embedded CO2 than new cells.
Safe and supported
CE and UKCA marked, every cell monitored 24/7, supported by the UK engineers who built it.
Proven
Already keeping the power on across the UK and Ireland

FAQ
Questions buyers ask
Can MAX charge EVs without a grid upgrade?
Yes. MAX stores energy slowly from the supply you already have, even a 32A connection, and delivers it at high power when vehicles plug in. J&M Murdoch runs DC fast charging from a 32A supply and deferred a £300k grid upgrade.
How much charging power can MAX deliver?
DC charging runs from 60kW up to 1.28MW across the range, with two outlets: MAX300 up to 400kW, MAX500 up to 480kW, MAX1000 and MAX1500 up to 1.28MW. MAX300 and MAX500 add 4 x 22kW AC. The power quoted is the total, shared when two vehicles plug in.
Can MAX power the chargers we already have?
Yes. As a buffer, MAX boosts satellite chargers on site, or charges vehicles directly from its own outlets.
Does MAX need a grid connection at all?
No. Off-grid, MAX recharges from any public or depot DC charger, another MAX or a generator. At Lower Thames Crossing, four MAX500s charge electric excavators with no grid connection.
