Abstract: A fastening device for mobility and a mobility including the same includes a first fastening unit provided in a first module of the mobility, and a second fastening unit disposed in a second module of the mobility, the second fastening unit coupled or decoupled to the first fastening unit for attachment or detachment between the first module and the second module, wherein the first fastening unit and the second fastening unit include a first fastening member and a second fastening member selectively screw-coupled together, respectively, the second fastening unit further includes a support member configured to support rotatably the second fastening member.

Abstract: A cooling system of an electric vehicle is provided. The system includes an integral valve having at least one or more coolant inlets and at least two or more coolant outlets, and selectively discharges a coolant through one of the at least two or more coolant outlets. A plurality of coolant paths connected such that the coolant discharged through one of the at least two or more coolant outlets is introduced back into the integral valve through the at least one or more coolant inlets after being supplied to a portion where coolant circulation is required. A heat pump device is disposed in at least one or more of the plurality of coolant paths to selectively increase or decrease a temperature of the coolant.

Abstract: An engine cooling system includes: an engine system including an engine having a plurality of combustion chambers that generate a driving force by combustion of fuel; a power electronics (PE) device that assists engine torque of the engine system in accordance with a driving state of the vehicle; a main radiator connected to the engine system by an engine coolant line and discharging heat generated in the engine system by engine coolant flowing in the engine coolant line, a sub-radiator connected to the PE device through a PE coolant line and discharging heat generated in the PE device by PE coolant flowing in the PE coolant line; a 2-way valve connecting the engine coolant line and the PE coolant line to each other; and a controller for controlling opening and closing of the 2-way valve according to a temperature of the engine coolant and a vehicle driving condition.

Abstract: A heating, ventilation and air conditioning (HVAC) system of a vehicle includes: an indoor air conditioning circuit which produces to supply cooling air to a vehicle interior by heat-exchanging inflow air through an indoor air inlet or an outdoor air inlet with an evaporator, and which produces to supply warm air to the vehicle interior or to discharge to the outside of the vehicle interior by heat-exchanging inflow air with a heat exchanger. The heat exchanger is connected with an engine cooling circuit so that engine coolant is used as a heat source of the heat exchanger, thereby improving the cooling performance of the ERG cooler.
