One of the biggest hurdles for anyone considering buying an electric car is the range. It is the distance an electric car can travel on a full charge. Considering one intends to travel along a highway, it becomes a serious problem.
But technology may have an interesting solution. What if there was a way to wirelessly charge a moving electric car? Sounds pretty insane but it isn’t too far away from reality.
Scientists at the Stanford University have been successful in wirelessly transmitting electricity to a moving object nearby. The technology can be applied to just about any product that needs wireless charging, once it is capable enough. Another area where this technology could excel is robotics, where we won’t need to tether them at all times.
The group of scientists at Stanford have been working on a technology that was developed back in 2007. The technology involved wirelessly transmitting electricity to an object lying stationary a few feet away. The team was successful in wirelessly providing electricity to a moving lightbulb with a 1-milliwatt charge.
While that may seem too low for any electric vehicle right now, but it’s a start. Electric cars would need about tens of KW of electric charge. The team at Stanford is now working towards increasing the electric charge so that the technology can be applied to more products.
Currently, electric cars have a very limited driving range. Another issue that remains is that they take a longer time to charge completely. If the scientists at Stanford are able to successfully develop a system to charge a vehicle on the go, it will help eliminate all these issues.
The team is considering a vision where electric cars can move along the highways without worrying about charging. Coils connected at the bottom of the car could receive wireless charging from another series of coils embedded in the road itself.
