Abstract
A battery cooling system which cools a plurality of battery units uniformly. The cooling system is provided in an electric vehicle with a longitudinal, hollow main frame provided with a plurality of branching ducts branching from the main frame to distribute cooling air to the battery units, a plurality of battery units arranged along the main frame, and a cooling fan connected to one end of the main frame. The flow passage area of the branch duct at a distal position with respect to an air flow inlet of the cooling air is smaller than those of the other branch ducts.
