Ancillary loads in vehicles are necessary for passengers and to regulates vehicular operations. They are independent of vehicle speeds but show-up as a constant power usage to perform duties. For instance, electric vehicles regulate traction battery operating temperature irrespective of driving style in all weather conditions only rely on traction battery as their sole energy source reduces electric vehicle mileage covered per charge.
Likewise there use in fossil-fuels run vehicles entails an increase fuel consumption also reduces miles per gallon -mpg rating and exhausts emit.
Todate auto-giants have developed techniques meant to minimize power consumption by the loads on heat ventilation air conditioning systems -HVAC use of light colours in the vehicle's interior to increase the overall cabin albedo, special IR -reflex glazing etc yet new generation vehicles still suffer from the bottleneck of ancillary loads.DRET 6kW generating set is a system designed to solve the lingering loads problem on vehicle by constant load ancillary systems causing limited mileage and pollution threats. It is a generator coupled to a speed increasing transmission and together fixed to the shafts of selected free rolling wheels can be either front or rear arrangements thus act as a prime mover. It turns the transmission, and transmission output drives the generator to produce electricity continuous. To work, the integral system depends solely on excess torque available at rolling free wheels whenever the main vehicle propulsion wheels transfer torques.So as the vehicle speeds progressively the tires resistances reduce significantly as torque develop is inversely proportional to speed-mph, corresponds to optimum rpm attain driving the generator to produce 6kW output. No extra fuel/ electric energy consumption rather excess torque develop by the wheels are tapped and utilized continuous to generate electricity inputs for ancillary loads onboard the vehicle except stop and go traffic jams entails fluctuations in power supply momentarily switch power back to the vehicle propulsion source(s) either ENGINE RUN OR TRACTION BATTERY to maintain its operation. And revert immediately as vehicle speeds.
BENEFITS AND APPLICATIONS
1)6kw electric output is used to power onboard ancillary loads in all weather conditions
2)In electric vehicles remains of the generator output can be employed as trickling charging process of traction battery to further increase the vehicle millage by 40%
3)It can be modified for use in midsized fossil-fuels and new generation hybrid vehicles to run ancillary loads and dispense with use of alternator, HVAC mechanical drives, pumps etc to improve fuel economy and indeed engine lifespan.
4)The wheels used serves propulsion duty and significantly act as prime mover to turn the generator, the whole system is environmental friendly.
