Bergstrom and Kohler Power Systems are offering the trucking market a hybrid power system that combines the Bergstrom NITE Plus System with the Kohler dc power unit. The system provides stable power to the truck, allowing the driver to run the HVAC system efficiently, without having to idle. When the power levels of the four deep-cycle AGM batteries decrease to low voltage levels, the low-battery indicator is triggered and the dc power unit begins to recharge the batteries while keeping the NITE Plus System operating uninterrupted. If the truck’s batteries are also depleted, the dc power unit can recharge them using the specified bi-directional separator with no risk of overcharging either bank of batteries. The system significantly reduces fuel consumption. In air-conditioning mode, no fuel is used because the truck operates solely on the NITE Plus System. In heating mode, 0.05 gal/h are consumed, while 0.10 gal/h is used when the hybrid power system is in recharge mode. The hybrid power system runs quietly with minimal maintenance required. The dc power unit features a sound-attenuated enclosure that keeps the unit operating at 68 dB(A) in recharge mode. When the system is in heating or air-conditioning mode, the sound level does not exceed 50 dB(A).

Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
