Auxiliary Power Units for Over the Road Trucks

Truck drivers are often forced to idle their trucks during required rest periods to provide heat, air conditioning, or electricity for other applications. An estimated 15.5 million heavy-duty trucks operate on U.S. highways, so reducing the amount of fuel wasted on idling can have a significant impact on our energy efficiency and security.

Auxiliary power units (APUs) are portable, truck-mounted systems that can provide climate control and power for trucks without idling. These systems generally consist of a small internal combustion engine (usually diesel) equipped with a generator and heat recovery system to provide electricity and heat. For air conditioning, an electrically powered air-conditioner unit is normally installed in the sleeper, although some systems use the truck's air-conditioning system.

The simplest APU is a direct-fired heater. Developed in the 1950s, these systems can be used to heat both the sleeper cabin and the engine as necessary. Direct-fired heaters cannot provide air conditioning or power for other applications such as a television or microwave.

More sophisticated auxiliary power units consist of a generator powered by a diesel engine, a compressor, an alternator, and an inverter/charger. These units are fully integrated into the truck's heating, ventilation, and air-conditioning system. In addition, the inverter/charger allows the system to provide electric power to the cab and sleeping compartment.

In the future we may be able to use a gasoline- or diesel-powered solid oxide fuel cell as a power source for an APU.

Benefits

Auxiliary power units can help truck drivers comply with local idling ordinances, reduce emissions and noise, and save on the cost of truck fuel and maintenance. Because most auxiliary power units are integrated directly into the truck's systems, they offer a high level of convenience. In addition, APUs are a proven technology that is widely available and is even sold as an option on some new trucks.

Costs

Auxiliary power units available today range in cost from $1,500 for direct-fired heaters (providing heat only) to $7,000 for auxiliary power units (combined cab heat/air conditioning, electric power, and heat to engine and fuel). The units also can add 300 pounds or more onto the weight of the truck—which has a negligible effect on fuel economy but could reduce the load that weight-limited trucks could carry.
