Abstract: A battery-mounted vehicle according to an example of the present disclosure accommodates one or a plurality of batteries under the floor panel. The battery-mounted vehicle includes a battery-cooler unit, a condenser, a refrigerant liquid pipe, and a plurality of refrigerant gas pipes. The refrigerant liquid pipe guides the refrigerant liquid from the condenser to the battery-cooler unit. The refrigerant gas pipe guides the refrigerant gas generated by vaporization of the refrigerant liquid from the battery-cooler unit to the condenser. The plurality of refrigerant gas pipes include a first and a second refrigerant gas pipes. The first refrigerant gas pipe extends in a first direction from the battery-cooler unit to the condenser, and connects the condenser and the battery-cooler unit. The second refrigerant gas pipe extends from the battery-cooler unit in a second direction opposite to the first direction, and is connected to the condenser by being bended or curved.

Abstract: The battery pack according to the present disclosure is a battery pack mounted under a floor of a vehicle. The battery pack comprises a lower case fixed under the floor and on which a battery stack is placed, an upper case attached to the lower case, and a support member extending upwardly from a rigid body provided inside the lower case to support a back surface of the upper case. The battery pack may further comprise an elastic member disposed on a surface of the upper case and sandwiched between the upper case and a lower surface of the floor. In such a configuration, it is possible to suppress the upper case of the battery pack from vibrating.
