Once the first generation of electric vehicles will reach the end of life for their batteries, local governments and battery producer will be facing a real problem. These batteries while they do not meet the requirements for the automotive industry any more, still have around 80 % of their initial capacity which makes them reusable in other applications. In order to do so, they have to be properly evaluated so batteries with similar characteristics are used in new battery packs. This paper analyzes three of the most common screening methods in terms of accuracy, complexity and operational time. This is done by developing a multi-criteria analysis, which scores each method.
