DC electric compressor-driven air conditioning system

A method of controlling a climate control system, the method comprising:

• receiving, from an operator, an operator parameter;
• measuring a vehicle parameter of a vehicle having an engine;
• driving, by the engine, a first alternator and a second alternator;
• selectively providing, based on the operator parameter and the vehicle parameter, a first alternator field current to the first alternator based on the operator parameter and the vehicle parameter;
• providing a second alternator field current to the second alternator;
• selectively providing, by the first alternator and based on the first alternator field current, a first electrical output;
• selectively powering, based on the first electrical output, an electric motor configured to drive a compressor of an air conditioner;
• selectively operating the air conditioner, based on the operator parameter and the vehicle parameter;
• and
• providing, by the second alternator, a second electrical output to the vehicle.

A non-transitory computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

• receiving, from an operator, an operator parameter;
• measuring a vehicle parameter of a vehicle having an engine;
• driving, by the engine, a first alternator and a second alternator;
• selectively providing, based on the operator parameter and the vehicle parameter, a first alternator field current to the first alternator based on the operator parameter and the vehicle parameter;
• providing a second alternator field current to the second alternator;
• selectively providing, by the first alternator and based on the first alternator field current, a first electrical output;
• selectively powering, based on the first electrical output, an electric motor configured to drive a compressor of an air conditioner;
• selectively operating the air conditioner based on the operator parameter and the vehicle parameter;
• and
• providing, by the second alternator, a second electrical output to the vehicle.
