Vehicles are a form of convenience in our daily life. However, while they bring with them an ease of commute, they also play a significant role in contributing to the pollution of atmosphere, leading to a phenomenon like Ozone layer depletion posing a threat to the existence of life on the only habitable planet known to man.
Another concern mankind has had is about the depleting fuel resources. These factors, along with many others have forced researchers to find alternatives which could possibly resolve concerns we have had, or still have, about vehicles more suited for a Greener Earth. This resulted in the birth of Electrical Vehicles (EVs).
The history of EVs dates back to somewhere in the 19th century. In the initial phases, EVs witnessed a decline in sales due to their high cost, low speed and short range compared to the normal internal combustion vehicles. However, the EV industry has shown remarkable progress in recent times, thanks to the growing environmental and fuel related concerns, which have made people take another look.
Normally, any venture would face initial hiccups which need to be overcome, so as to reach the path to success. The EV industry was no exception. One prominent issue was that buyers of EV were worried about the availability of charging stations to recharge their vehicles. As a result, EVs were never a preferred option for long drives, as people feared running out of fuel in no-man’s land. However, as the EV industry grew, more and more companies show interest in launching electrical charging stations. US based Tesla Motors is a prominent player in this market.
A recent patent publication (US 20130057209 A1) from Tesla is about a multi-charging Supercharger which comes with many additional features compared to existing charging stations. The charging mechanism claimed in this patent application is capable of charging vehicles after considering various parameters including vehicle arrival time, driver’s preferred departure time, battery’s size, state of charge etc. The system is also capable of providing a fee based charging mode using which a vehicle/driver can get charging priority by paying extra.
Another interesting feature maybe that of enabling the charging mechanism to be used for promotional purposes. For example, the charging system may give priority to customers based on parameters such as vehicle manufacturer/model, mode of payment, type of card used by customers (Visa, MasterCard) etc., which may prompt users to choose specific brands while purchasing cars, cards etc.
The patent indicates that companies foresee a bright future for the EV industry and with more companies joining in the mission to provide required facilities for EV users, we may soon get to see more EVs on our roads. Let’s be optimistic and await an era of Green transportation.
