Our nation's fleet of 2.5 million Class 8 trucks consumes a staggering 28 billion gallons of fuel and generates over 300 million tons of CO2 per year. For truckers that normally bring 2% to 5% to the bottom line, fuel purchases of $50,000 to $130,000 per year that represent 35% of direct operating cost are critical.
We have developed an engine-dominant series hybrid electric drivetrain for Class 8 trucks that replaces the typical 450 hp engine with a 240 hp engine and uses battery boost for acceleration and hill climbing.
While the national average fuel economy for Class 8 truck fleets is 6 mpg,. Our third-generation drivetrain is expected to deliver fuel economy of 9 mpg in the 80,000 pound weight class and double digit fuel economy for combinations in the more common 55,000 to 70,000 pound weight range. All components used in our drivetrain are sourced from first tier manufacturers and have impeccable track records for reliable performance. Therefore, we do not face the problems associated with developing custom components. Each component is readily available as an off-the-shelf item and its cost is a known factor, up front. The strength of our system is the way proven components are integrated into an elegantly simple drivetrain that delivers extraordinary fuel economy. Long-haul truckers that log 120,000 to 200,000 miles a year and switch to our series hybrid drivetrain can expect payback periods of 10 to 18 months.
Our third-generation drivetrain is based on an EPA compliant on-road Cummins 6.7L diesel engine that’s mated to a 120 kW generator from Marathon and provides the principal motive power. Electricity from the genset is routed through an AC Vector drive from Unico, along with supplemental boost power from an array of 56 PbC batteries from Axion Power, a unique lead-carbon asymmetric capacitor that offers extraordinary cycle-life and charge acceptance, and fed to a 150 hp Marathon drive motor that can be overrated to 380 hp for acceleration and climbing. A 5-speed automatic transmission from Allison and a suite of proprietary cruise control and drive-by-wire electronics round out the package. Our first drivetrain patent was issued by Mexico in December 2013 and efforts to secure global patent coverage are ongoing.Type your paragraph here.
