About Allye
An ally for the grid, the people and the planet.
Say it
Allye
/ˈæl.aɪ/ AL-eye
We are an ally with a silent E. Allye is said like ally, and the E stands for the things we work for.
Energy
The product, and what it delivers.
Environment
The purpose behind what we build.
Electric
EV batteries and electric transport.
Economy
Reuse costs less than buying new.
Everyone
The people we make our promise to.
Our story
Two forces are colliding.
The grid can't connect new demand fast enough, and EV batteries are reaching the end of their first life with most of their capacity left. Allye puts the second to work on the first.
We take battery packs from the EVs already on our roads, keep their automotive battery management and liquid cooling, and build them into MAX: flexible energy storage that boosts a constrained connection, replaces diesel generators and charges electric vehicles. First life on the road. Next life on the grid.

Designed and built in Britain
From our 14,500 sq ft facility in London.
Every MAX is designed, engineered and assembled in London, with over 90% UK-sourced components. Our UK engineering team monitors and supports every unit, because they built it.
