Decommissioned electric truck batteries as energy storage systems for truck-charging stations - A feasibility study

Other conference contribution, 2025

In the electrification transition, both electric trucks and an infrastructure for truck charging needs to be developed. Electric truck batteries have capacity left when decommissioned and could potential be given a second-life as energy storage system. This paper develops a cost-model to assess whether or not it will be financially viable to install decommissioned truck batteries at a truck charging station. A mixed integer linear programming cost minimization is formulated to optimize the use of the batteries where the battery acts as energy and power buffer for charging the fleet of the transport operator and ancillary services in the form of frequency containment reserve for disturbances.
