BRUSA Elektronik announced that it started developing the next generation of its Inductive Charging System (ICS) to meet growing market demands.

ICS 2 will boast twice the charging power to 7.2 kW compared to ICS, but will have the same compact footprint.

According to the Swiss company, increase in power density has been achieved thanks to a special technology patented by BRUSA and we will see a prototype of the second-generation ICS as early as Autumn 2014.

Market launch is scheduled for 2017, so this is still 3 years from now.

“Development of the first generation also continues unabated. As the power electronics are fully integrated, the BRUSA ICS only comprises two components. The two primary and secondary coil housings already contain all the AC/DC converters as well as the communications and safety equipment for vehicle positioning and foreign-object detection. This means no external wall box or HF cabling is required – an absolute first for inductive charging systems. With the ICS BRUSA has achieved a power-transfer efficiency of over 90 percent, making it almost lossless. Indeed, the CarTec Awards jury was so impressed it named it winner in its category. Currently, BRUSA is working hard on making the ICS ready for mass production, with testing also taking place under everyday conditions as part of a small fleet trial.”

The wireless charging logo should show two metal plates with a cartoon cat getting fried, between them. It would be very eye catching. 😉

You meant “cat-ching” 😉

There is not much space left between the two plates and even if it could get in between the magnetic flux would not fry a cat since it is not metal.

Growing demands? Really? I hope that is true but EVs are barely a market as is and I’d suspect wireless charging systems are a submarket of a submarket.

If EVs are to be any sort of success or even stay in production they will have to massively expand.

In that case there is plenty of room for subsectors.

But I would argue that this expansion will come as EVs come down in price, not as they add expensive systems that increase convenience slightly while also increasing operating cost slightly due to decreased efficiency.

I hope the charging rates keep going up, while the costs keep going down.

This is an exciting time for wireless charging- congrats to Brusa!

It seems like a good idea, but it would also be interesting to know the power loss with the system, and if it can be retrofitted to existing cars.

Efficiency is typically 90-95% and can be retrofitted to existing cars in most cases.

Well, I paid $800 for my 6kwh leaf charger. I guess I would pay another $800 for the ability to just drive over the charger.

Technically, you can drive over your charger today for free. Might damage it, though.

The Plugless Power L2 is only at 3.3kW which works well for overnight charging of plug-in hybrids and 80 mile EVs.

But 7.2kW would make inductive charging viable for daily public charging.

Interesting that the onboard charger for the new eGolf is also 7.2kW.

Brusa also has the 22kW onboard charger.

Soon we won’t have to think about actually charging, because the car will be charged whenever it’s parked.

But public Inductive Charging systems will also need a payment system like Visa, where you register once, and you are good on all available inductive chargers, coast to coast.

When I talked to Evatran, they have 6.6kW charging in development for their current system already on sale. I can’t say exactly for obvious reasons. Needless to say, it’s not a big change technically.

wow 7kw
that’s gooood

I will get my plugless charger within the next two weeks.
First in Quebec so, the company is flying a tech guy to help with first install. It will be done at a GM dealer that is Volt crazy and very excited about the whole project. There is only one part that goes under the rear of the car and it should take about 1.5 hour to install. Just plug and play.
Efficiency is now 95%, it was 90 at first. Thats what i was told by the company.
After 2 years of owning my Volt, the cool factor just went up for me!:)

That’s going to be very nice. Just drive up at home, virtually dock and charge.

5 TO 10 % loss on 7,2 KW start to be significant. If there is an increase in charging power they will have to improve to 99 % efficiency or else an under the car secured contacts base system will definitively be more interesting. Beside, secured contacts based systems under the car will be needed anyway when we come to “Park & Forget” supercharging (100 KW level) and it will be paramount when we are at hypercharging (MW level).

Hey… it doesn’t look l like a toilet seat!
