Methods and systems are provided for maintaining a desired engine coolant level and a relative glycol amount in the engine coolant by using water sourced from on-board vehicle systems. In one example, a method may include supplying water to the engine coolant reservoir in response to the engine coolant level decreasing below a threshold. Also, a relative glycol amount in the coolant may be maintained at a threshold amount by adding water to the coolant in response to a relative glycol increasing above the threshold.

A vehicle includes an engine air intake having a humidity sensor, and a system having a nozzle positioned in the air intake and fluidly connected to a reservoir. The vehicle has a controller configured to activate the system to deliver fluid from the nozzle into the intake while the engine is inoperative and generate a diagnostic code in response to a change in humidity measured by the sensor being less than a threshold value. A method of controlling a vehicle includes measuring a baseline humidity (H1) using a humidity sensor in an air intake of an engine, and controlling a misting system to mist fluid from a reservoir into the air intake and adjacent to the humidity sensor while the engine is inoperative. The method measures a post-fluid delivery humidity (H2) using the humidity sensor, and generates a diagnostic code based on a comparison of H1 and H2.

AWG system (102) installed on, or coupled to, an apparatus (100) such as a vehicle, which may either have (i) a heat emitting element 106 which may provide residual heat that is produced by the apparatus (100) to the manufacture, treatment or dispensing of the water (112) generated by the AWG (102); (ii) a power source which may provide power to the manufacture, treatment or dispensing of the water (112) generated by the AWG (102) or (iii) an element which may benefit from the water (112) or dehumidified air that is produced by the AWG (102).

A cooling apparatus for cooling a battery in a vehicle by means of a coolant includes a first coolant circuit including a first heat exchanger for heat transfer between the coolant and the battery, a pumping device, and a collecting vessel for the coolant connected to one another by means of coolant lines. A condensate line connects the collecting vessel to an air conditioning system of the vehicle for the introduction of condensate. A related method for cooling a battery is also disclosed.

A system for transferring harvested drinking water from a vehicle to a trailer towed behind the vehicle includes a vehicle reservoir for collecting water from a vehicle heat-exchanger. The reservoir includes a heating element for heating water within the vehicle reservoir. A vehicle controller is coupled with the vehicle reservoir and is programmed to boil the water in the vehicle reservoir. The controller is further programmed to measure a fill level of the vehicle reservoir. A trailer reservoir receives water from the vehicle reservoir. A trailer controller is coupled with the trailer reservoir and is programmed to measure a fill level of the trailer reservoir. The trailer controller is further programmed to transmit a wireless communication to the vehicle controller. The wireless communication is indicative of the fill level of the trailer reservoir. A fluid conduit fluidly connects the vehicle reservoir to the trailer reservoir.
