A hybrid system that does away with dependence on conventional batteries; promises on-board charging, no battery pack replacement and far lower costs
Battery-fuel hybrid technology, while still far from being considered mainstream, is not niche either. Overseas, the hybrid market is quite developed and virtually every manufacturer has some hybrid on offer. In India too, various types of hybrid vehicles are on sale and finding quite a few buyers.
Motor unit fixes to hub and capacitor pack location varies depending on model packaging in question.
Hybrids can be classified into three categories based on their assists. The first, called Micro Hybrids, are basically start-stop systems that switch off the engine automatically when the vehicle is stationary and the battery powers the electrical equipment. The second are Mild Hybrids which have propulsion via an engine alone or the engine and an electric motor. The electric motor, however, cannot power the vehicle alone. The third are Full Hybrids which can have propulsion from only the engine, only the electric motor or from a combination of both.
38 percent fuel was saved
The Ayataiq system uses ultracapacitors as a power source in a full hybrid setup. Being capacitors, the charge cycle is very quick and thus, charging the pack is done fully on board while the engine is on. This does away with the need to plug in and charge. The company has fitted a mass market Indian scooter with the system and the bike can be ridden from rest to 30kph with ultracapacitor power. The system can also be used under dual-power mode with both the ultracapacitor and engine power. In August last year, the bike was tested at the ARAI test facility in Pune using the homologation drive cycle IDC (Indian Drive Cycle) and an average of 38 percent fuel was saved compared to its standard counterpart.
Compared to an expensive lithium-ion battery system, the ultracapacitor system is far cheaper, does not need replacement through the life of the vehicle and with charging on board, also does not require any charging infrastructure. This makes it very useful in emerging markets like India. Ayataiq is currently working fast towards commercialising the two-wheeler system and also a four-wheeler system.
