Nissan is aiming to create a way to fast-charge electric vehicles without the hassles of charging cords and cables. The company is working on a high-voltage wireless inductive system based on electromagnetic fields to solve EV charging problems.
Electric vehicles give a lot of comfort compared to traditional cars that needs fuel and pollutes the air through carbon emissions. Still, electric cars require the use of charging cables and cords which is a stressful job.
Currently, automakers are trying to solve this problem. Soon enough, companies will bring wireless charging systems and smart controls to every electric vehicle in their lineup.
In line with this, Nissan is working on a 7-kilowatt wireless inductive charging system. The system will be a big advancement from the current 3-kilowatt standard that uses power cords.
During the Tokyo Motor Show, a Nissan official states that 3 kilowatts is not enough to fast-charge electric cars, and that the car company is focusing on a way to fast-charge its vehicles through wireless inductions. The method could easily charge high-capacity lithium-ion batteries for long distance trips. This technology could be an option for the Nissan Leaf and other vehicles on the carmaker's lineup.
For years now, Nissan has worked on its inductive charging technology. Bosch, a charging system supplier, even demonstrated its own technology that can fit a garage floor to charge up electric vehicles like the Leaf and Chevrolet's Volt. The system that the carmaker is working on is reportedly a lot more flexible and stable. Company officials noted that vehicles positioned four inches away from the 'bulls-eye' is ideal for wireless charge-ups.
The wireless inductive charging system should work around four to six inches between the inductive charging pads with 85 percent charging efficiency, which is a significant upgrade from the present standards. This could also mean more height for traditional-sized passenger vehicles and crossover-type vehicles and SUVs. The system will be using electromagnetic fields carefully designed to pass concerns about pacemaker and other device interference.
