Abstract
Systems and methods to power electric vehicles are disclosed. A battery pack to power an electric vehicle is provided. The battery pack residing in the electric vehicle. The battery pack can include a plurality of battery modules. Each of the plurality of battery modules can include a plurality of battery blocks. A first battery block can include a plurality of cylindrical battery cells. Each of the plurality of cylindrical battery cells can have a pair of battery cell terminals and can have a voltage of up to 5 volts across the pair of battery cell terminals. The plurality of cylindrical battery cells can be electrically connected in parallel within the first battery block. Each cylindrical battery cell of the plurality of cylindrical battery cells can be spatially separated from each of at least one adjacent cylindrical battery cell within the first battery block by less than 2 millimeter (mm).
