Abstract
A battery module with air cooling capability that includes at least two battery blocks; the battery blocks each include a plurality of cylindrical round cells arranged in corresponding receptacles of a cell holder, wherein longitudinal axes of the cylindrical round cells lie parallel to one another; air passage openings are provided in the cell holders, through which air can flow through the battery blocks in parallel to the longitudinal axes of the round cells; the battery blocks are stacked on one another with spacing so that a stack intermediate space results between adjacent battery blocks in the stack; a housing, including the stack made up of the battery blocks, wherein the stack is spaced apart from walls of the housing so that two terminal free spaces result between terminal battery blocks of the stack and the walls; the housing has at least one air inlet and at least one air outlet; a fan is assigned to the battery module to generate an airflow between the air inlet and the air outlet, and guiding means that ensure that the airflow is guided starting from at least one stack intermediate space between two adjacent battery blocks through the air passage openings in the cell holders between the cylindrical round cells of the individual battery blocks and through the terminal free spaces in a direction of the air outlet.
