Abstract
The invention is related to a battery cell module comprising two end battery cells and a number of intermediate battery cells arranged between the two end battery cells to form a row of battery cells. At least one of the two end battery cells is electrically coupled in parallel with at least one intermediate battery cell, allowing state-of-charge of the parallel coupled battery cells to be balanced. Thereby, achieving an improved balancing which can reduce uneven aging of the battery cells in the battery cell module and increase the life-length of the battery cell module.
