Bergstrom Inc. and Kohler Power Systems have joined forces to offer the trucking market a hybrid power system. This system combines the Bergstrom NITE Plus System with a KOHLER DC power unit.
The hybrid power system provides stable power to the truck, allowing the driver to efficiently run the HVAC system 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 KOHLER DC power unit begins to recharge the batteries — all while keeping the Bergstrom NITE Plus System operating uninterrupted. Should the truck's batteries also be depleted, the KOHLER DC power unit can recharge them using the specified bi-directional separator, and at no risk of overcharging either bank of batteries.
When the system is in the air-conditioning mode, no fuel is used, as the truck operates solely on the Bergstrom NITE Plus system. In heating mode, 0.05 gallons per hour are consumed, while 0.10 gph is used when the hybrid power system is in recharge mode.
The hybrid power system from Bergstrom and Kohler is certified to EPA Tier 2 emissions regulations. It is also CARB-compliant, except for the time when the system is recharging.
This system will be available in summer 2009. The Bergstrom NITE Plus carries a two-year warranty, and the KOHLER DC power unit carries a two-year or 2,000-hour warranty.
