Second Life Energy Storage

Solutions based on batteries that have gone through a first life in vehicles.

We know that our future is at stake.

That's why we are committed to supporting the shift towards a circular economy in everything we do.

Reuse and recycling lie at the heart of our business, and everything we do is grounded in a deep respect for our planet’s limited resources. This is our contribution to a circular economy and our way of taking care of the planet and the limited resources we have available.

Tonnes of CO2

saved per building by using second-life batteries as energy storage. Energy storage improves the utilization of energy produced by renewable sources, reducing the need to purchase power from other sources.

178+

Kg of CO2/kWh

saved when compared to using new batteries in energy storage. Making new batteries consumes energy and generates CO2 emissions. Repurposing batteries enables storage without increased CO2 emissions.

20+

GWh

storage in second-life batteries will be available for energy storage in 2025. If the rest of the world follows Norway´s lead, over the coming decades, this number will surmount to terawatt hours.

A battery´s first life

We call a battery´s life in an EV its first life. As transportation becomes electrified, the number of electric vehicle batteries in circulation increases.

Repurposing first life batteries to a second life

Once EV batteries are removed from the vehicle they still have a significant capacity, providing high performance, low environmental impact solutions for less demanding applications.

Recycling batteries at the end of lifetime

At the end of the second life, we recycle the batteries, making use of the raw materials to produce new batteries.

Residential Energy Storage

System setup and control is provided by
a simple App that enables the user to
operate the system in several different
modes:

  • GENERAL MODE - PV supplies load as a
    priority, then charges the battery and
    finally feeds surplus to the grid. If there
    is insufficient PV, the batteries supply the
    load. Battery and grid supply load
    together if demand exceeds battery
    power.
  • ENERGY STORAGE MODE - PV and
    grid supply the load and charge battery
    together. Battery SoC is maintained at
    100%. If there is insufficient PV the grid
    supplies the load and charges the
    battery.
  • PEAK & VALLEY MODE  Four sub modes can be configured based on Time of day. These can define the priority of the source that supplies the load. The stored battery energy or excess PV can be pushed to the grid when demand from the load is low.
  • MICRO GRID - PV supplies load as a
    priority, then charges the battery with
    excess energy. When PV is no longer
    available the battery supplies the load.

Industrial Energy Storage

Designed for ‘behind the meter’ use in
business and industrial premises our
industrial energy storage systems take a
modular approach to simplify system
development.

Based around two electric
vehicle batteries, the basic building block
has a minimum of 40kWh of storage and
can deliver up to 30kW of power. Modules
can be connected to build larger systems in
the range of 40kWh to 500kWh.

The system incorporates an Energy
Management System (EMS) that can be
configured to meet your specific application
requirements and integration with your
Building Management System (BUMS).
Suitable for a wide range of storage
applications including peak shaving, grid
support, frequency regulation, electric
vehicle charging and increased utilization of
solar.
