Electronics technology may provide significant contribution to the development of electric vehicle technology by enhancing the travelling autonomy of this type of car, i.e. the average distance that could be travelled between two consecutive charges of its batteries, (see Figure 1):

Another important parameter that has to be taken into account when talking about electric vehicles is the elapsed time to recharge the batteries that, in many cases, has to be added to the average time between two consecutive charges to evaluate the overall autonomy of the electric vehicle. (see Table 1):
“Time to charge an electric car can take as little as 30 minutes or up to 12 hours . The time it takes to charge depends on the size of the battery and the speed of the charging point.”
The time for charging an electric car depends on the characteristics of the charging point and by the size of battery as well. (Source: pod POINT)
It is evident that supercapacitor technology would be a perfect solution to realize the energy storage setup of electric vehicles, but there is a drawback of a low density of energy storage allowed by this type of capacitor. Till now.
The autonomy of electric vehicles may be dramatically increased indeed by a new discovery of a gel that increases the capacitance of electrolytic capacitors by 1000+ times actually sold on the market (see Figure.2):
“Ground-breaking research from the University of Surrey and Augmented Optics Ltd., in collaboration with the University of Bristol, has developed potentially transformational technology which could revolutionize the capabilities of appliances that have previously relied on battery power to work.
- Major scientific breakthrough research has discovered new materials offering an alternative to battery power and proven to be between 1,000-10,000 times more powerful than the existing battery alternative – a supercapacitor.
- The new technology is believed to have the potential for electric cars to travel to similar distances as petrol cars without the need to stop for lengthy re-charging breaks of between 6-8 hours, and instead re-charge fully in the time it takes to fill a regular car with petrol.”

The new technology may represent a revolution for the electric cars technology with a positive impact on the environment because electric cars produce no CO2 emissions (Source: University of Surrey)
Electronics technology could find a development boost from this new option to realize rechargeable supercapacitors that are going to be utilized as an important component integrated into the electric vehicle (see Figure 3).

What do you think of this new solution that increases the autonomy range and the time between recharging of electric vehicles? Do you think it will be a good solution for electric transportation especially inside urban areas reducing the emissions of CO2 and ultimately air pollution?
