RFID Revolutionizes the Electric Vehicle Industry

Electric Vehicle ChargingRemote car starters. Curtain side airbags. Cars that you can talk to and that talk back. Those luxuries are old news these days, having made their way into almost every car on the road.

Wireless cars that are connected to databases of information as well as connected to each other are being reported on a lot in the media today. It won’t be long before those cars are on the road telling their drivers where they can go for Sushi, and if they have a new email which can be displayed on the dash for safe viewing.

Electric cars were once thought of as futuristic, but these too have become a reality. Down the road (pun intended!), we should expect to be surrounded by them. Right now they are mostly compact and well suited for driving and parking in space-constrained metro areas. But because of the advantages they afford us, we see that industry grow, and grow successfully in part, with the help of RFID.

First let’s take a step back and review what RFID has done for the automotive industry as a whole.

Location of Cars

How many times have you been so ready for a vacation, eagerly taking the keys from the rental car agent, only to spend 30 minutes waking around a hot parking lot with your family and suitcases because you can’t find your car? We’ve seen how RFID with GPS makes this practice a lot more convenient for the customer and far more efficient for the rental agency. The benefits are clear: visibility of all cars in the lot; immediate availability of cars as they are needed; improved inventory management so popular cars are on-hand more often; and reduction of paperwork and manual record keeping. A no brainer!

Parking Garage Access

The type of RFID implementation to locate cars also works for fleet management and parking garage access and payment. Long-range identification in combination with high-speed RFID is the best option for hands-free identification of cars as they enter and exit a parking facility. Parking facilities and parking garages at airports feel the pressure to find ways to grow revenue. RFID helps achieve that goal by bringing increased efficiency, security and convenience, while minimizing environmental impact. Pretty soon we won’t need to remember to bring our parking tickets with us to pay the cashier before we leave a garage, which is obviously not very convenient.

Anti-theft

We’re not talking about LoJack, although that does use radio frequency for location tracking. We’re referring to a use case where European manufacturers used RFID as “car immobilizers.” The keys are equipped with an RFID tag, and an interrogator installed in the steering column. In order to start the vehicle, the reader validates the unique identification number from the RFID-enabled key. A duplicate key would not be able to start the car because it wouldn’t be able to pass the reader’s verification without the tag.

Recharging Stations

Now, getting back to the electric car. The advent of this development has brought about another automotive market need that RFID is helping to serve - wireless charging stations.

EV-Charge America’s approach to electric vehicle charging stations uses a wireless, networked, meshed-LAN array of subscription-based stations that can be located anywhere with Google Maps, OnStar, hand-held devices and smartphones. Once at an EV Charging Station, drivers can unlock it, activate it and start the flow of electricity by waving their RFID-enabled key ring in front of the unit's reader.

To charge an EV at IKEA San Diego, drivers swipe their RFID-enabled Blink InCard, plug the charger into the EV, and then shop at their leisure in the IKEA store while the vehicle is charging.

Coulomb Smartlet charging stations will eventually let drivers use an RFID-enabled credit or debit card to pay for their electricity.  Subscribers are issued cards equipped with a high-frequency passive RFID tags so they can simply hold their card up to an RFID interrogator embedded in the Smartlet unit.

A ZigBee transceiver, compliant with the IEEE 802.15.4 standard, is used to pass the captured data to a ZigBee gateway, which then passes the data to a central server containing software that validates the card's ID number and account status – in real-time. Not to mention that the signal between the card and reader will be encrypted to secure the data transmitted by the cards. Without this added protection, people would most likely hesitate to take advantage of the benefits of paying with RFID credit and debit cards.

In the same way that RFID is reshaping aspects of the retail and healthcare markets, it is revolutionizing the Electric Vehicle industry which is still arguably in the nascent stage. If it can help shape an industry that has not had time to mature, imagine what RFID can do for a well established industry.
