EOL-IS joint project


End-of-life solutions for e-vehicle batteries (EOL-IS)

Services and Decision Support for the Repurposing and Further Use of used Traction Batteries from Electric Vehicles

 

EOL-IS-LogoElectric Vehicle Batteries must be removed from a car prematurely

An immature battery technology appears to be the crucial obstacle to impede a quick diffusion of electric mobility in Germany. One core factor are the high initial costs of traction batteries (electric car batteries), which cause electric vehicles to be up to two times as expensive as vehicles propelled by a combustion engine. To improve an electric vehicle’s total cost of ownership (TCO), batteries that are not any more sufficient for a demanding automobile life can be repurposed and further used in alternative second-life scenarios. By definition, this End-of-(First-)Life (EOL) is reached as soon as the battery can store less than 80% of its original electric capacity, which leads to a decreased acceleration and driving range of the electric vehicle.

 

Electric Vehicle Batteries can be repurposed to other scenarios

Depending on the technical properties of a battery, different second-life scenarios can be realized. For instance, a battery or its components can be used to propel smaller vehicles (e.g., a light-electric vehicle (LEV) such as golf cars or wheel chairs), to store green energy in stationary applications such as in smart homes, or to power semi-residential devices such as electric lighting, which can be used on construction sites. Already from the year 2020, we can expect a significant amount of electric vehicle batteries that are available for second-life applications, generating an appreciable business opportunity for second-life scenarios.

 

The EOL-IS project designs innovative services and decision support systems for repurposing Electric Vehicle Batteries

The EOL-IS project’s goal is the analysis and development of new services that enable or accompany the second-life of electric vehicle batteries. From our point of view, the complex requirements of customers who are interested in such energy storage solutions can best be addressed by the offering of integrated product-service systems, consisting of the electric vehicle battery as well as mandatory and optional services, such as repurposing, start-up, maintenance, and refurbishment. Based on a battery’s individual technical properties, its usage history, and its condition, a custom-fit product-service system needs to be configured. A to be developed decision support system will support and simplify the matching between suitable batteries and second-life batteries as well as assist in the configuration of a customer-specific solution.
