Electric hybrid conversion system design and assembly for 3 wheeler vehicle(such as auto rickshaw).

摘要

The presented invention deals with the conversion of a petrol/CNG/Diesel run three-wheeler in to a plug-in hybrid electric three-wheeler. Such a three-wheeler would have two sets of powertrain A.) Existing 2 or 4 stroke IC engine which uses petrol/CNG/Diesel as fuel B.) Electric motor which is operated by battery power The powertrain configuration for this hybrid three-wheeler would be - 1.) Electric BLDC Hub motor mounted in the front wheel and providing a direct drive to the front wheel 2.) IC engine in its existing layout driving the rear wheels through a gearbox and differential arrangement The range of the three-wheeler is improved as a result of the "mile extender" feature of the invention by 90% (per litre per charge basis) on the city test route selected for the test vehicle. Above all there is substantial environmental benefit as the fuel consumed per kilometer of driving the three-wheeler reduces significantly thereby reducing the C02 emissions. The vehicle can also be run in an absolute "zero-emission" mode when it is being driven purely on battery power by the electric motor thereby reducing the pollution in congested cities and in residential areas. The design of the auxiliary powertrain system of electric motor is such that it gets installed on the three-wheeler with minimum modifications to the frame and body of the existing three-wheeler. This invention helps to convert the existing three-wheeler into low emissions, fuel saving vehicle - i. It increases the life expectancy of the existing vehicle (by making the vehicle compliant with stricter emission norms) thereby benefiting the owners of existing three-wheeler from economic standpoint, this would be quite a help for such community who often belongs to a low income group, ii. Provides a cost-effective solution to reduce the emissions from vehicles that are already on the road, thereby contributing substantially in migrating to clean transportation mechanisms which would be complementary to sales of new electric or hybrid vehicles, iii. Helps in conserving the usage of fossils based fuel thereby helping in reducing the import bill of fuel for the nation iv. Helps in reducing the healthcare expenses of urban population likely to benefit from improved air quality due to reduced carbon emissions v. Added benefits such as improving living conditions in urban areas thereby increasing the prospects of growth of such economy vi. Strengthening country"s position in climate change negotiations with other countries The performance specifications of such PHEV will improve with further advancements in technology of electric powertrain components such as battery, motor, controller, BMS, etc.
