SIMPLE AND MODULAR ASSEMBLY OF BATTERY CELLS USING PRINTED CIRCUIT BOARDS

A rechargeable battery pack includes: a plurality of battery cells, each battery cell of the plurality of battery cells having a positive terminal and a negative terminal, an upper surface and a lower surface, the positive and negative terminals being arranged on a same side on the upper or lower surface or alternatively arranged on the upper and lower surface, the plurality of battery cells being arranged in a first direction and in a second direction, orthogonal to the first direction; a mechanical support structure for the battery cells; at least two printed circuit boards for electrical interconnection of the battery cells arranged on the upper surface or the lower surface, or both; and means of electrical interconnection by contact and without welding between the battery cells and the printed circuit boards allowing a connection of the battery cells in series and/or in parallel.
