No.88 (2022) NISSAN TECHNICAL REVIEW

Special Feature2 : Next-generation flagship: ARIYA - 2. Development of EV-specific platform CMF-EV for high packaging efficiency

The aforementioned functional integration were

included under the premise of stiffness of the vehicle

body frame structure from the beginning of the planning

stage. Consequently, precise maneuvering performance,

comfortable riding experience, and mass reduction, which

are the expectations of the customers from an EV, have

been realized simultaneously.

4. Layout of the air-conditioning unit in the

motor room

The realization methods are described in more detail

from this section forward. The position of the air-

conditioning unit, which was previously situated in the

instrument panel of the cabin, was relocated to the motor

room to realize a thin instrument panel. This change was

introduced during the world premiere of ARIYA and has

been well known since then.

However, changing only the mounting position of the

unit hardly contributes to improving the ratio of effective

interior to overall vehicle length (i.e., packaging efﬁciency

in the front-rear direction). This is attributed to the fact

that as the interior space is elongated, the motor room

housing the air-conditioning unit must also be extended.

The breakthrough realized in ARIYA is that in addition

to the positional change of the air-conditioning unit,

measures are provided to the structure so that the air-

conditioning unit absorbs energy on impact. As shown in

Fig.

, the air-conditioning unit was previously mounted

at the rear side of the dash panel (i.e., in a non-crushable

zone). If the air-conditioning unit is relocated to the

motor room and crush stroke is maintained, extending

the motor room is necessary to accommodate the front-

rear length of the air-conditioning unit (Fig.

For the CMF-EV adopted in ARIYA, the air-conditioning

unit was built to be crushed so that the necessary crush

stroke could be secured, and the front-rear length of the

motor room was shortened (Fig.

). The air-conditioning

unit primarily comprises a heat exchanger, refrigerant

pipes, blower fan, and duct. Because the components other

than the heat exchanger and blower fan motor are made of

resin or have hollow shapes, there is some allowance for

crushing. Therefore, the Force-Stroke characteristic for

collision was assigned to the air-conditioning unit when

developing ARIYA by assuming that the air-conditioning

unit body will be crushed to approximately

200

mm during

a full-frontal collision. Of the air-conditioning unit

components, the air PTC heater, which requires high

voltage, was placed within the cabin (non-crushable zone)

in consideration of high-voltage safety during collision.

A method for predictably crushing the air-conditioning

unit during a frontal collision is described herein. Fig.

shows the layout diagram of the CMF-EV motor room.

The air conditioning unit is mounted on the rearmost

side of the motor room. The upper powertrain unit, which

is an assembly of the battery charger, junction box, and

DC-DC converter, is mounted on the front side.

During a frontal collision, the upper powertrain unit

starts retracting from the intermediate stage of the

collision event, and the maximum amount of retraction

occurs at approximately the same time as when the air-

conditioning unit is completely crushed. To achieve

predictable crushing of the air-conditioning unit under

various types of collisions, it is desirable for the upper

powertrain unit to retract while maintaining the initial
