Direct High-Speed Charging of Electric Cars by Solar Panels

Direct Charging of Electric Cars

Charging Electric cars via a solar panel

Electric cars are now the “in thing”. With this fad on the up and up, many are now looking for ways to charge the car in ways that can be energy efficient. The whole point of these electric cars is that they should not take up much fuel and can be charged from renewable sources of energy that does not require the burning of fossil fuels, which would otherwise be the same thing as filling up the car with all fuel. Therefore researchers have now discovered a novel way to charge these electric cars using solar energy.

Researchers are now considering charging electric cars using solar panels. By using this method of charging the cars, people will not only save the environment from the burning of fossil fuels but will also be using a renewable source of energy, this is besides getting tax concessions.

Charging electric cars using solar panels and their problems: 


Present practice in using a solar panel means that charge from the solar panel has to be converted from direct current to alternating current to charge an electric car. This normally would require a 50Hz AC network, to convert the direct current into alternating current.

But this method is not really beneficial for anyone. In that it is not cost effective or efficient. This is because of two main reasons. To convert current to AC involves a lot of costs and needs many steps. Secondly, to convert from DC to AC requires two converters one for the solar panel and the other for the car, again leading to high costs and installments.

What’s the solution then? 


A better alternative as discovered by the researchers is to use a single converter that charges the car from the panels via a DC link which connects to the AC electricity grid.

Researchers then came up with a 10kW converter that has an internal DC link and three terminals that would allow the car to charge both from the solar panel and the electricity grid.

What’s so good about this method is that the integrated DC charger has a higher efficiency and is three times smaller than the current practice.

Another advantage of using this method is that not only will you be able to charge your car, you will now also be able to charge your entire house using this new method. You could also return the electricity back to the grid that is not before first converting it into AC.

The Future of Charging Electric cars: 


This system can be expanded to connect several chargers to solar panels thus expanding its use to business parks and residential areas. The company Power Research Electronics has gone a step further and made this theoretical system a reality by developing a number of high speed charging stations of this type.
In this way electric cars will not only consume less fuel, thereby burning less fossil fuel and in turn less damage to the atmosphere, but will also earn tax concessions by using a renewable source of energy.
