The transport sector is facing the problem that the battery capacity of long distance trucks is insufficient to keep up with the fast growing electricity demand. Idling the main engine - during rest periods - is often used to generate the required electrical power. This results in unwanted noise levels, pollution, engine wear and high fuel consumption.

MTT CAP Unit on a long distance truck

MTT is developing a low cost and reliable APU (Auxiliary Power Unit) that enables the truck driver to generate (up to) 3 kW of stable electricity during his rest period. It will be combined with a parking heater that will generate up to 6 kW of thermal power to be used for cabin heating and main engine preheating.

Recent studies show that the investment in a CAP unit will have a payback time of approximately 12 - 18 months.
