Solar Based EV Charging Stations: The Smart Card to Push the EV Bandwagon

There seems to be a global understanding to pull plug on the consumption of energy resources, owing to the fast depletion of the resources as well as to curtail the emission of green house gases.
IC engine based motor vehicles are one of various contributors to the exponential growth in energy consumption. Also they contribute heavily to the emission of green house gases.
While considering contributions of transport to GHG emissions, every form shall be considered like rail, shipping, commercial road, passenger road and airways. Based on emissions data, the contribution of commercial and passenger road vehicle is particularly high.
In a country like India, almost 14,00,000 vehicle get registered every year. The resultant incremental GHG gas emission estimates arrive at alarming figures.
The concept of electric vehicles has been doing rounds for decades. Various entities have developed and commercially promoted them. However in an apple to apple comparison, EV’s have failed on myriad counts to a traditional IC motor vehicle.
The resultant public response has been lukewarm.In the years gone by, however, various technological developments have facilitated development of vehicles that can match the performance of IC motor vehicles. EV’s have slowly gained traction and relevance in the market. The Indian government has also started devising strategies to push the market for EV and program a systemic shift from IC motor vehicles by 2030.
Technically speaking EV means Electric Vehicle. This means that prime mover in the vehicle is run on electricity i.e. Electric motors. Compared to a traditional IC motor vehicle an EV has fewer moving parts and hence expends lesser on maintainance.
The most prominent technology prevalent these days is battery based electric vehicles,popularly known as BEV. BEV’s fully run on rechargeable battery and has no clutch or gears, spark plugs or exhaust. Recently launched BEV’s have achieved mechanical efficiency matching a conventional IC engine. Also with recent new developments in battery technology, recharging times have been been lowered drastically.
Now, for an electric vehicle to truly make the difference it intends, the source of electricity has to be non-conventional ans renewable. The current available infrastructure still depends on the electricity generated by traditional methods, thus offsetting the purpose. Considering the aggressive targets set by the government, the rising scale of adoption will only increase this dependence.
Various renewable sources of energy like solar, wind and hydro-energy need to be tapped to rectify this anomaly. On closer observance of the strengths of each source and the architecture of the refueling infrastructure, solar just seems to fit the bill over the rest.
Closely considering, solar power generation is capable of large scale decentralization and can be effectively utilized at individual charging points. Also being so close to the point of generation T&D inefficiencies can be practically pushed out. This also helps relieving the impact of extra loading on the grid.The economies of scale that have been realized with the increasing demand for solar power coupled with more effective storing technology can help realize widespread adoption of EV vehicles in future. Solar comes across as a perfect match for EV’s and the future seems bright for EV market integrated with latest solar technologies.
