A wiper system for vehicles is provided. The system includes a heated wiper blade assembly, a heated cowl assembly and a controller. The controller receives input from one or more sensors or systems and causes a power source to provide, reduce or stop power to heating elements in the blade and/or cowl depending upon sensed conditions. At least some components in the assembly comprise thermally conductive polymers. The system provides surprisingly advantageous results in that it is effective for melting and clearing ice and snow with a lower than expected pull on a power source such as a battery.

A vehicle includes an inverter, a climate control system, and a coolant system. The climate control system includes a housing, and a heater core and an electric heater disposed within the housing. The coolant system includes conduit arranged to circulate coolant through the inverter and the heater core. The inverter is disposed upstream of the heater core.

The cord harness including a series of guard sections and hinges facilitating a foldable protective design for wiring. The air conditioning apparatus may attach to a supporting assembly configured to fit in a cupholder. The supporting assembly may be configured to fit multiple cupholder designs. The air conditioning apparatus and supporting assembly may include additional accessory components.

The present disclosure relates to a heat pump device for an electric vehicle, and more particularly, to a heat pump device that constitute three types of independent refrigerant cycle in which three different types of refrigerant flow respectively, and disposes a first heat exchange unit and a second heat exchange unit in which the refrigerants exchange heat with each other, in the refrigerant cycle, thereby performing an integrated heat management of an indoor space, a battery, and a driving module.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include a heating body positioned inside an HVAC duct of the vehicle, formed between a first electrode portion and a second electrode portion having polarities opposite to each other. The heating body is configured to generate heat when the heating body is electrified to increase a temperature of an air being transported through the HVAC duct.

An air conditioner includes an inside condenser, an outside heat exchanger, an inside evaporator, a refrigerant circuit switcher, and an air passage switcher. The refrigerant circuit switcher is configured to switch a layout of the refrigerant circuit to (i) a first circuit during a heating mode such that the refrigerant releases heat at the inside condenser and is decompressed to evaporate at the outside heat exchanger and (ii) a second circuit during a defrosting mode such that the refrigerant releases heat at the outside heat exchanger and is decompressed to evaporate at the inside evaporator. The air passage switcher is configured to switch the air passage to (i) a first passage during the heating mode such that the air passes through the inside evaporator and the inside condenser and (ii) a second passage during the defrosting mode such that the air bypasses the inside condenser.

System and methods are provided for improving fuel economy, and providing optimized operating conditions associated with a vehicle's air-conditioning system when the vehicle is carrying a load, e.g., towing a trailer. Operating conditions including, for example, air-mix setting, coolant temperature, ambient temperature, vehicle speed, and whether or not the vehicle is carrying the aforementioned load, may be considered when determining whether or not to activate or deactivate a vehicle heating element, such as a positive temperature coefficient (PTC) heater, steering wheel heater, etc.

A waste heat utilization system for an electric vehicle having an electric motor and a battery may include a first cooling circuit in which a first coolant circulates and having arranged therein the electric motor, a first direct heat exchanger for discharging heat from the first coolant into surroundings of the system, and a first delivery device for driving the first coolant. The system may also include a second cooling circuit in which a second coolant circulates and having arranged therein the battery and a second delivery device for driving the second coolant. The system may also include an air conditioning circuit in which a working medium circulates, and having arranged therein a compressor, condenser, and evaporator. The system may further include first and second chillers by which heat may be transferrable from the first and second cooling circuits into the air conditioning circuit, and first and second heat exchangers incorporated in one of the first and second cooling circuits for discharging heat into the surroundings.

A heating apparatus for a vehicle includes an air heating unit configured to heat air conditioning air to be sent into a vehicle cabin, a contact heating unit configured to heat a member that is in contact with a body of an occupant in the vehicle cabin, and an electronic control unit. A heat source of the air heating unit and a heat source of the contact heating unit each are supplied with an electric power from one or more batteries. The electronic control unit is configured to decrease an electric power that is supplied to the heat source of the air heating unit when the heat source of the contact heating unit is on as compared to an electric power that is supplied to the heat source of the air heating unit when the heat source of the contact heating unit is off.

A heater assembly includes a base panel; a heating member disposed behind the base panel opposite a heating target space; a thermal conductive film having a film shape, attached to an outer surface facing the heating target space of the base panel, and transmitting heat of the heating member to the outer surface of the base panel by having an end portion extending behind the base panel and coupled to the heating member; and a shield layer preventing the thermal conductive film from being directly exposed to the heating target space by being attached to an outer surface facing the heating target space of the thermal conductive film.
