Structured precision,every step
From EV battery to energy storage system. Designed, built and tested in Norway.
It starts in the ground
Extracting the materials for a battery is hard on the environment.
The raw materials are mined from the earth, and every new battery leaves a footprint in water, land and energy before it ever powers anything.
Use the batteries already made. As well as possible, for as long as possible.
The footprint is paid the day a battery is made. Every extra year of use makes it worth more.
From car to storage in five steps
We control every level ourselves, from the cells to the software that runs them.
- 01
Source
Used EV batteries, and new ones that never made it into a car.
- 02
Module
We redesign them into our own industrial modules and string controllers.
- 03
Control
The Mulligan BMS talks to every battery, tailored to each project.
- 04
Integrate
Drives and energy management complete the system, tested at every stage.
- 05
Operate
Live monitoring and service through Mulligan Dispatch.
From car to storage, up close
Second-life batteries only work as well as the system around them. That’s why we build the whole system ourselves.
We give batteries a second chance
We use two kinds of batteries: batteries that have done their job in a car, and batteries that never made it into one because carmakers often buy more than they need, or change plans and designs along the way.
Most of their capacity is still there. We build them into energy storage that keeps working for years.
Moving batteries from one use case to another means new designs
In a vehicle, batteries are installed in a fundamentally different way than in an industrial system. To make these batteries suitable for use in an industrial product, we design and manufacture our own battery modules and string controllers.
This makes integration into complete systems seamless.
We need to talk to the batteries to operate them
For reliable communication and precise control, we customize our MULLIGAN BMS to meet each project’s specific requirements. We therefore have the capability to adapt to the second-life batteries available on the market today and to accommodate new battery options as they emerge in the future.
Control of the supply chain gives us the power to make the best possible solution for the end user
Our systems are tailored at every level — from the cells and modules to the BMS, drives, and energy management systems.
This gives us full control over the production process and the quality of the final result.
Live, after delivery
After the systems are delivered, this integrated approach also gives us a unique position to operate, maintain, and service them effectively.
Every system reports to Mulligan Dispatch: grid, converters and battery strings, live, down to each cell.
