Abstract
In contrast to numerous published lithium-ion cell ageing investigations, reports regarding the ageing behaviour of entire modules are scarce. This study compares the ageing behaviour of lithium-ion battery modules with the one of single cells. A capacity-based cell matching procedure is performed to minimise the capacity spread among the blocks of constructed modules. So, the newly introduced state of inhomogeneity (regarding capacity and resistance) is reduced up to 10%, but, however, also observed to increase rather linearly over the modules
