A housing for carrying a plurality of rechargeable batteries is configured such that air gaps defined adjacent to the batteries have a continuously-decreasing cross-sectional area. Cooling air being directed through the air gaps thus increases its speed in inverse relationship with its temperature rise such that all of the batteries are cooled to substantially the same degree. All of the cells of the batteries thereby accept electrical charge at a substantially uniform rate.

An electric vehicle comprising: a plurality of rechargeable batteries; an elongated tubular housing having a longitudinal axis extending from a forward end to a rearward end and sized to carry end-to-end a plurality of rechargeable batteries of predetermined size, wherein the housing is sized such that an air gap is defined between itself and the plurality of batteries, the air gap having a cross-sectional size that continuously decreases from the housing\s forward end to its rearward end; and air cooling means for transporting air through the air gap defined by the housing, from the forward end to the rearward end, the air being heated by the batteries as it is transported through the air gap, and thereby cooling the batteries, wherein the speed of the air continuously increases as it is transported along the air gap, due to the air gap\s continuously decreasing cross-sectional size, to enhance the air\s heat transfer coefficient in inverse relationship with the temperature differential between the air and the adjacent batteries, wherein the plurality of batteries are provided with a substantially uniform cooling effect and are maintained at a more uniform temperature.
