摘要： In a battery cooling structure, a battery case housing a large number of battery modules is formed into the shape of a rectangular tube having a cooling air inlet and a cooling air outlet, and V-shaped cooling air guide channels having a decreasing flow-path cross sectional area are provided on inner faces of air guide plates that define upper and lower faces of the rectangular tube. The flow of cooling air is deflected by these V-shaped cooling air guide channels toward a central part on the downstream side, thus effectively cooling the battery modules disposed in the central part, for which the cooling effect is poor to make uniform the temperature of the battery modules, resulting in a suppressed variation in capacity and lifetime. Moreover, since it is not necessary to provide a bypass passage in the battery case, it is possible to simplify the structure of the battery case, reduce the dimensions, and improve the degree of freedom in the layout.

摘要： In a power supply unit disposed below a floor behind a seat, battery modules are disposed in a lower position, and a DC/DC converter and a motor driving inverter are disposed side by side in a vehicle width direction above the battery modules. Thus, cooling air flowing from the front side to the rear side of a vehicle body is divided into upper and lower portions to cool in parallel the DC/DC converter and the motor driving inverter on the upper side and the battery modules on the lower side. Thus, it is possible to simplify a passage of the cooling air to reduce the size of the entire power supply unit, and improve mountability of the power supply unit on the vehicle body. Also, it is possible to apply low temperature cooling air, before heat exchange, to the battery module, the DC/DC converter, and the motor driving inverter.

Thus, cooling air flowing from the front side to the rear side of a vehicle body is divided into upper and lower portions to cool in parallel the DC/DC converter 41 and the motor driving inverter on the upper side and the battery modules on the lower side. Thus, it is possible to simplify a passage of the cooling air to reduce the size of the entire power supply unit, and improve mountability of the power supply unit on the vehicle body. Also, it is possible to apply cooling air at low temperature before heat exchange to all the battery module, the DC/DC converter, and the motor driving inverter, thereby enhancing cooling effect.
