BatteryLoop is a fast-moving and growing company developing solutions for large-scale battery energy storage systems based on re-purposed electric vehicle batteries. We invite our suppliers to be part of this exciting journey, and share our success in delivering reliable, safe, and competitive products and services.

This success is based on important requirements on quality, business ethics and industry practice.

When a battery cannot be used in an electric vehicle it still has 70-90 % left of its capacity, which allows us to use them in our systems. Thus, by using second-use batteries we prolong their life before being recycled. Depending on the usage and cycling of the batteries, during normal circumstances we expect the batteries to have still 70-80 % of the capacity left after 10-15 years.

Such prolonged lifetime of electric vehicle batteries does, however, require their incorporation into an energy storage system of appropriate quality standards and assurance.
