Available across the product range, PHETT units are fully rechargeable from an appropriate electrical supply. The AC traction motor is coupled directly to the axle, whilst a standard Tier IVi 50bhp diesel or gasoline GenSet supplies power to the electric motor to rotate the drive wheels and charge the battery, if required.
The GenSet is capable of being powered by alternative fuel including LNG, CNG, or hydrogen when the latest technology is available. The vehicle produces far less pollutants including NOx and particular matter, as well as air toxins and green house gases.
This first model is diesel powered and with such a small power unit it is expected to reduce the NOx carbon footprint by 90% ppm compared to a standard 200 hp diesel engine. When operating in full electric mode there is a 100% reduction, with the added benefit of being noise-free.
The company claims that each kWh of battery power displaces approximately 0.1 US gallons of gasoline or diesel, with no on board fossil fuel used during all electric range. As a result fuel efficiency increases due to the engine being used at maximum efficiency, as it is sized for average usage rather than peak power usage. This in turn results in lower maintenance costs.
