The present disclosure provides cab heater systems for electric vehicles. The first system includes a combustion chamber having a combustor inlet, a combustor outlet, and a hydrogen storage fluidly coupled to the combustor inlet configured to supply hydrogen to the combustor for combustion. The second system includes a fluid circulation pump, one or more cabin heat exchangers, a heat transfer tube fluidly connected to the fluid circulation pump and to the one or more cabin heat exchangers, and an insulated tank. The insulated tank includes a tank heat exchanger fluidly connected to the heat transfer tube, a resistance heater, and a phase change material. In the charging mode, the resistance heater provides heat to the phase change material and to the tank heat exchanger, while in the heating mode, the fluid circulation pump provides heat to the tank heat exchanger and to the one or more cabin heat exchangers.

A method of efficiently heating a passenger cabin of a vehicle includes heating a first fluid using a fluid heater. The first fluid flows through a thermal storage element to transfer thermal energy to the thermal storage element. The heating of the first fluid and the thermal storage element occurs during a recharging of a rechargeable power source used to power the vehicle. During operation of the vehicle and following discontinuation of the recharging of the rechargeable power source, the thermal energy stored to the thermal storage element is transferred to air to be distributed to the passenger cabin of the vehicle by flowing the first fluid through a first heat exchanger in thermal communication with the air to be distributed to the passenger cabin of the vehicle, thereby extending a range of the vehicle.

A method for heating a vehicle is disclosed. The method comprises heating coolant with an electric heater and selectively heating the coolant with an engine. The method further comprises selectively supplying the coolant to each of a plurality of heating zones, and calculating a heat load of heat exchangers corresponding to the heating zones. The heating of the coolant is based the heat load in the heating zones.

A radiant heater air-conditioning system includes: a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior; an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion; and an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior. The air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set.

Systems and methods are provided for cooling and heating in a vehicle. A thermoelectric cooling system can include a heatsink in thermal communication with an exterior of a vehicle, thermoelectric cells within the vehicle mounted to the heatsink, and a power supply electrically connected to the one or more thermoelectric cells. In response to receiving power from the power supply, the thermoelectric cells produce a temperature difference to draw heat from the vehicle in to the heatsink. Cooling a vehicle cabin can include receiving a desired temperature and a current temperature of a vehicle cabin, determining a temperature difference between the desired temperature and the current temperature, and, based on determining the temperature difference indicates the desired temperature is lower than the current temperature, causing thermoelectric cells to receive power so the thermoelectric cells produce a temperature difference to draw heat from the vehicle cabin in to the heatsink.

An information processing device that controls a vehicle including a plurality of heating devices. The information processing device executes acquiring an air conditioning request transmitted from a user terminal, and selecting a heating device to be operated, among the heating devices in which an operation is specified by the air conditioning request, based on a remaining battery amount of the vehicle.

Systems and methods of controlling temperature in a cabin of an electric vehicle that has an HVAC system powered by a battery system and an auxiliary heating system. Upon determining, by a system controller, that a setpoint temperature is less than or equal to a sensed cabin temperature while operating in an HVAC electric heat state, an auxiliary heat state, or a maximum heat state, automatically transitioning to an off state from the HVAC electric heat state, the auxiliary heat state, or the maximum heat state.

According to some embodiments, a zonal conditioning system for a vehicle comprises a headliner assembly configured to be secured to the top surface of a vehicle interior, wherein the headliner assembly comprises a first side positioned away from the vehicle interior and hidden from the vehicle interior, and a second side positioned toward the vehicle interior, the headliner assembly comprising at least two vents through which air selectively passes. The zonal conditioning system further includes at least two fluid modules positioned along the first side of the headliner assembly, wherein each of the fluid modules comprises a fluid transfer device and an outlet. In some embodiments, at least one property of the air discharged through the first and second vents can be selectively regulated to create separate conditioning zones within the interior of the vehicle.

A control system for a radiant heater device includes a radiant heater device, a heater ECU that controls an energization and a deenergization of a heat generation unit, and an integrated ECU that transmits an operation prohibition command for prohibiting the energization of the heat generation unit and an operation permission command for permitting the energization of the heat generation unit to the heater ECU. The integrated ECU transmits the operation prohibition command when receiving a collision signal indicative of a vehicle collision or a prediction of the vehicle collision, and transmits the operation permission command when not receiving the collision signal. The heater ECU performs the deenergization control when a non-reception state in which the operation permission command is not received from the integrated ECU is continued for a predetermined time or more. As a result, the energization can be interrupted before an occupant is adversely affected.

An electrically driven vehicle includes: a vehicle body provided with the vehicle interior, a battery which is mounted to the vehicle body and is able to be used for running, an electric heater which executes an air-conditioning operation which uses an electrical power of the battery when air-conditioning vehicle interior, a power generation device which is at least partly removably mounted to the vehicle body and executes another air-conditioning operation other than the air-conditioning operation which uses the electrical power of the battery when air-conditioning the vehicle interior, and an air conditioning change unit which changes the use state of at least one of the electric heater and the power generation device.
