Inductive charging is an excellent example of how intelligent electric vehicle technology helps to overcome range anxiety in electric buses.
On a recent post I looked at range anxiety which was very well received with lots of useful feedback afterwards from Dukosi blog’s readers. Regardless of whether you agree with me that range anxiety is mostly a psychological issue or not, there is no doubt that it is a big barrier to electric vehicles adoption. Today, I’m turning my attention to how we can reduce it with intelligent electric vehicle technology. To address this, I’ll be looking at inductive charging and how it works for electric buses.
So what exactly is inductive charging?
I invited Joel Sylvester, Dukosi CTO, to help us understand how inductive charging works:
“Inductive charging may already be familiar to some people, even if they don’t know it by that name. The wireless charging mechanism that some smart phones use is inductive. Your phone has a wire loop within it, and the charging pad has a similar loop inside it. When your phone is placed on top of the charging pad, the two loops form a transformer. It’s a very flat and not hugely efficient transformer, but it still operates to transfer power from the charging pad to the phone. The same technique can be used to charge suitably equipped vehicles, but with powers of many kilowatts rather than watts.
The relatively poor efficiency is made up for by there being no unsafe exposed connections, no cables, and no wear and tear. A bus equipped with inductive charging can pull up at a bus stop fitted with an inductive charging loop buried in the road and take a boost of charge for the few minutes the bus might be waiting. The bus driver does not need to get out of the cab to hook anything up. This regular topping up could help EV bus operators extend their use to longer routes”.
More than a trend
There is a fast-growing trend of developing cordless technologies which are easy to use and give us freedom to do other things on the same time. This includes various technologies including mobile phones and tablets to electric cars and buses.There are some additional benefits that inductive charging offers to electric vehicle drivers such as safety as there are no exposed conductors. Additionally, research suggests they can assist in public acceptance of electric vehicles due to perceived practicality and convenience.I think you’ll agree that these benefits are significant to educating people about electric vehicles which is key to reducing range anxiety.
The case for electric buses
So that’s how inductive charging works for electric buses. Korea’s Advanced Institute of Science and Technology (KAIST) has already introduced this innovative charging technology in electric buses . With fixed routes routes and inductive charging infrastructure available throughout, electric buses can never run out of battery charge as they charge while on the go. To that end, inductive charging can significantly help to overcome range anxiety. Transport for London has also recently announced trials of inductive charging in its electric buses.
With novel, intelligent electric vehicle technology, we can ensure that range anxiety can gradually be reduced in all electric vehicles’ categories. In this blog, I’ve looked at inductive charging and how, when used in electric buses, it can help to maximise their range and make drivers feel convenient and secure.
Thanks for taking the time to read through this post. I’d love to hear your thoughts on range anxiety and if you agree that exploring new electric vehicle technology is key to dealing with this issue. Feel free to get in touch at Twitter and Linkedin.
