Israel to test wireless charged electric vehicles for public transportation
Plugging in electric cars might be a thing of the past as an Israeli start-up prepares to test its new technology that allows vehicles to be inductively charged while driving on roads with buried coils.
According to Inhabitat, the company has reached an agreement with local authorities in Tel-Aviv in order to experiment with one of the electric buses that provides public transportation. Electroad is convinced that its technology will allow for a different approach to public transportation.
Electroad is a start-up that focuses on revolutionizing public transportation, eliminating the dependency on oil and enabling of large scale adoption of pure electric buses in cities. Electroad takes a different approach than other conventional enterprises by trying to eliminate the limitation of the energy storage capacity given by batteries. According to Electroad, the battery weighs 1/3 of the vehicle, reduces the potential use space, costs almost half and encompasses range limitation. Moreover, the costly need to replace the batteries every few years only decrease the potential penetration of electric public transportation.
Trying to solve this problem, Electroad came up with a new technology, called the Dynamic Wireless Power Transfer that allows electric buses primarily to run without batteries and to use induction in order to get the power they need. According to the schematics, roads are provided with metal coils and as the bus drives over them, it gets its much needed power. The vehicles are still provided with a battery that gives them an autonomy of several kilometers but this is much lighter and smaller than those used today. This makes the bus easier and thus it takes less energy to move it forward.
The DWPT system devised and tested by Electroad will be implemented on a public transport line in Tel Aviv. According to the Jewish Business News, the tests will be conducted in the northern part of the city where copper hoops are being placed under the asphalt. This chain will be linked to a converter positioned at the side of the road. The test are carried out in order to asses how the system copes with traffic and weather conditions.
The municipality’s Department for public transport has already invested a lot in providing clean vehicles in order to protect the environment and lower CO2 emissions. If the technology proves to be efficient, in the future there will be no need for charging our electric vehicles.
