A method for operating a cooling system of a motor vehicle for cooling at least one component, a cooling system of a motor vehicle for cooling at least one component, and a motor vehicle having such a cooling system. The cooling system has a coolant circuit and a refrigerant circuit. The coolant circuit serves for cooling the at least one component and the refrigerant circuit and the coolant circuit are coupled thermally to one another via a heat exchanger. The coolant circuit has a conveying device for conveying a coolant in the coolant circuit. A cooling power of the refrigerant circuit can be regulated. The regulation of the cooling power of the refrigerant circuit is realized in a manner dependent on a return temperature of the coolant and/or on a temporal development of the return temperature of the coolant.

A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.

An electric drivetrain for installation in a vehicle chassis. A generator coupled to an engine generates electric power for charging an array of batteries. The vehicle, including components and subsystems, may be powered electrically from the batteries, allowing the engine and generator to be easily replaced or customized for an industry, geographic region, fuel type, or a set of emission requirements. A thermal management system may determine a battery temperature for the set of batteries and cause one or more of a coolant system, a refrigerant system, an exhaust gas system, or an ambient air heat exchanger to add heat to the set of batteries or transfer heat away from the set of batteries.
