Video: Qualcomm Shows Us How Halo Wireless Charging Works


Wireless charging of plug-in vehicles seems to be where we’re headed at some point in the future.

The advantages of wireless charging are numerous and include ease of use and no need for standardized plugs/connectors.

The disadvantages are lack of efficiency and the need to align the vehicle rather accurately over a the charging pad.

As Qualcomm says, it’s only a matter of time before automakers begin producing plug-in vehicle that are wireless charging capable.  Qualcomm CMO, Anand Chandrasekher, says the company is in talks with most automakers and is confident that its system will be used commercially very soon.

Quoting Chandrasekher

“There are a few [suppliers] that are already building with our technology, so within the next few years, hopefully we’ll see some of this in market.  “If you’re looking for something that’s not commercial but in production, the Drayson Racing cars are in production using our technology.”

So, wireless charging is already here, but not in a big way yet.  The BIG leap to wireless seems inevitable though and with how easy the video makes it look, we don’t see why one wouldn’t want to charge wirelessly versus plugging in.

I’m not aware of any wireless charging standards, like there are for EV Plugs…

I’m a sceptic. Just because manufacturers push a new technology doesn’t mean its inevitable. Many are just gimmicks. Look at 3d tv.

The glossed over issue of inefficiency is not a minor issue. And it’s debatable if plugging in is really that hard especially at home. In public, if you have to check in or login to a site anyway again it’s not clear how much time it’s saving over plugging in.

I see a lot of benefits to charging wirelessly. No need to manage a cord, which means no worrying about the length, coiling it up, mashed connectors, charging points that get run over, and vandalism (remember that copper theft is still rampant).

The technology has advanced in the past decade. The charging and receiving pads are tuned to each other. I was skeptical of the 90% efficiency claim, but my colleagues have seen the evidence in real-world tests and operation. Halo has been used in the bus system in Torino, Italy since 2003.

The video seems to be a plea to have a single worldwide wireless charging standard, and I think the odds of that happening are extremely low. Naturally, Qualcomm wants it to be their proprietary standard which they will receive a royalty for each unit.

Not going to happen, since everybody will want in on the gig.

I do think that this will be the future for low end cars that might only have a 10kWh battery in a cheap $10k car. That is only possible if the car is charging all the time, and wireless in parking spots and on certainly roadbeds can do it.

Clearly, for “real” cars, really fast conductive charging (CHAdeMO, Supercharger, et al) will continue to rule the day.

There are lots of worldwide wireless standards. Wifi & Bluetooth are 2 examples. The standard needs to be open source.

I think the biggest hurdle for wireless charging is not the efficiency, but the power rate. I think L2 (3.3kW) is where a lot of mfg’s are, and there maybe one that is at 6.6kW (going from memory here). But for it to compete long term, it needs to be closer to where DC charging is now. That’s a tall order. The other option is putting chargers EVERYWHERE, including stop lights, and eventually in the highways for on the fly charging, but even then, they need a transfer rate of at least 25kW.

Faster please.

It sounds amazing, if those promises about misalignment tolerance and efficiency are true.

I would also add that a proper system of data transfer between car and pad is necessary. The present system of having to *swipe* a card over a charger that is going to link to your car is absolute stupidity in this day and age. In fact I was stunned to find out that common l2 chargers don’t exchange any data at all except a square wave proportional to car charge. Give me a break, this is the computer age. Let me enter the payment details into the car and have it take care of it.

Does anyone know the details of the “charger highways” thing? Does it mean having a charger pad every foot or so? That is going to add up fast (cost).
