A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.

Power source device and battery cooling structure for vehicle

Provided is a mounting structure for a battery in an electric vehicle capable of increasing a driving distance of the electric vehicle by mounting a plurality of battery modules in an existing vehicle body of en electric vehicle. The mounting structure for a battery in an electric vehicle according to an exemplary embodiment of the present invention includes a main relay box electrically connected with an inverter, a plurality of first battery modules mounted beneath the rear seats of the electric vehicle, and a main housing positioned between a pair of front seats in the electric vehicle and below the rear seat. More specifically, the main housing is configured to house the main relay box and first battery modules therein, and is fixed to the vehicle body of the electric vehicle.

A cooling system for a battery in a vehicle does not use air from the vehicle passenger compartment, but rather, takes in ambient air from outside the vehicle. When the temperature of the ambient air outside the vehicle is low enough, the air is moved through a duct system by a pair of fans and blown across a battery assembly. When the temperature of the ambient air outside the vehicle is too warm to cool the battery directly, it is first passed through an evaporator coil where it exchanges heat with a refrigerant, prior to being blown across the battery assembly. The cooling air may be recirculated across the battery assembly, or exhausted from the vehicle through an air extractor.

A rotor and each magnet are configured to satisfy one of the following conditions: (Dπ/Z)×n+T<X<(Dπ/Z)×(n+1)−T and (Dπ/Z)×(n−1)+T<X<(Dπ/Z)×n−T. Here, Z is a number of cores. D is an outer diameter of the rotor. T is a circumferential dimension of a tooth of each core. X is a circumferential dimension between a circumferentially innermost one of first and second opposing points of a first tapered portion and a circumferentially innermost one of first and second opposing points of a second tapered portion. The first and second opposing points radially oppose first and second imaginary end circles, respectively, defined by outer peripheral surfaces of the cores. Furthermore, n is the number of the teeth that are entirely placed within a range defined by X when a circumferential center of one of the teeth is radially opposed to a circumferential center of the range defined by X.
