Wireless vehicle charging

iStock_000034846188MediumMany believe eMobility to be in its diapers still. This view is not entirely correct. Actually, the industry is already producing usable vehicles and the infrastructure around eMobility is improving significantly year by year. Businesses of every size are working hard to bring about what many refer to as the “Iconic Change” – a new dawn for mobility in general. Take the latest developments in battery charging technology, for example: wireless charging is said to hit the market soon making plugs and cables redundant. Will eMobility be sprinting off now?

Old technology reinvented for modern purposes

Right now, charging an electric vehicle can be a bit inconvenient at times. While there are a few challenges, overall, cable charging has been experiencing quite the evolution: the average time it takes to fully charge a battery today is significantly shorter than only a couple of years ago. However, some of these remaining challenges are said to be resolved by wireless charging. Yes, it’s fully wireless. Based on the principle of inductive power transfer, discovered by Serbian-American inventor Nikola Tesla last century, a handful of companies offer this new charging method. It’s very simple: a primary coil is placed on the ground covered by a protection case. The second coil is installed underneath your car.iStock_000001073200Medium So you park your car in such a way that the two coils are in close proximity to each other. Then, the first coil generates an electromagnetic field, which induces a current in the second coil. The car’s battery is being charged. In case you were wondering, and you probably were, wireless charging is not faster or slower than charging by cable. But it is so much easier to integrate into the existing infrastructure: one company solely deals with installing wireless charging on manhole covers.[1]

Pro or con?

The range of possible applications is immense: As a test, a hybrid bus was charged by wireless technology during every stop in London.[2] Although, it was charged only for a couple of minutes every time, the accumulative effective did make a difference. While all this sounds very advanced, it is exactly this trend of coming up with something new every couple of months that could prove to be hazardous to the overall development of electric mobility. What do you think? Is wireless charging beneficial for the establishment of electric mobility into the market place or does it overwhelm the costumer with yet another new fancy invention?
