Siemens Energy Management Division, together with Duke Energy and Ford, recently demonstrated the results of an 18-month project on residential smart charging capabilities to lower energy costs and, at the same time, assure grid reliability.

The project was granted by the U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability.

Siemens developed a lot of additional features for its EVSE to make charging smarter – schedule charge periods, see usage statistic or even let utilities to control charging periods.

According to Siemens, if utilities were able to control the charging process, energy bills could be lowered up to 60% compared to standard rates. We believe that real world benefits would be less, as the base scenario for electric car owners is typically already two tariff rates, including one for night charging.

General sales of EVSE with Wi-Fi connectivity and smart phone application used in this demonstration is expected to be available in 2015.

“Held at the Duke Energy Envision Center in Erlanger, Ky., and utilizing a Ford Fusion Energi Plug-In Hybrid, Siemens provided the first Underwriters Laboratories (UL) approved residential electric vehicle supply equipment (EVSE) to demonstrate the ability to monitor status, report energy use, and be controlled locally from the local area network and from the cloud.

Siemens’ EVSE was shown to be accessible by web-connected computers, smart phones and tablets, allowing the EV owner to better monitor the status of the EV charging, schedule future charge events, as well as determine the total kilowatt hours consumed and the cost of charging.

With these technology developments, an EV owner can now better understand exactly what they are spending to charge their electric vehicle, schedule the charging process when rates are lowest, and share their charging experience. Utilities can also take advantage of the technology to offer programs that help manage the time and level of EV charging across the grid to increase grid reliability and efficiency while minimizing peak demand.”

Barry Powell, head of Siemens Low Voltage & Products stated:

“This demonstration marks a turning point for the EV industry and proves the tangible benefits of bringing advanced EVSE technologies into the home and the power marketplace. Intelligence in EV charging stations means homeowners can reduce the cost of charging up to 60 percent by automatically charging during low energy rate periods, where such programs are available. Utilities can shift loads off critical peak periods to avoid the need for new generation sources.”

Mike Rowand, director, Technology Development at Duke Energy remarked:

“As EVs gain in popularity, it will be important for both drivers and utilities to have improved information — making charging more available and cheaper.”

Control the EVSE from an OpenADR server

“Also demonstrated was the ability to monitor and control the EVSE from an OpenADR server. OpenADR is an open standard for Automated Demand Response, allowing utilities to manage grid load resources remotely and automatically. By using OpenADR or by directly accessing the Siemens Cloud, utilities can offer rate programs to EV owners to allow the consumer to charge at highly attractive rates while simultaneously allowing the utility to manage the loads on the grid. By shifting each EV charging event slightly in time, utilities can potentially reduce the peak demand on the grid, which in turn helps to reduce the total amount of generation needed.

The Siemens EV charging station presented at the Envision Center also demonstrated a unique, new industry standard interface designed to allow appliances to work with utility demand response programs. The connection is based on the CEA-2045 modular communications interface standard, introduced in February 2013 by the Consumer Electronics Association (CEA). Electric Power Research Institute (EPRI) is assessing the CEA-2045 interface to determine its ability to provide smart grid connectivity standard for water heaters, AC units and other large home energy loads. This Siemens EV charger is believed to be the first EVSE that provides this connectivity. In addition to the CEA-2045 connector in the EVSE, Siemens also demonstrated a CEA-2045 communication module that provides Wi-Fi communications for any CEA-2045 enabled appliance.”

Such savings programs have already been implemented by most utilities, although without the “Smart Grid” paraphenalia which some Utilities say they don’t want.

DTE (Detroit Edison) offers a discount rate if you own a registered (that is, you drive it) EV. No changes happen at the house; savy owners do all their dishwashing and laundry to also benefit for the low Time-Of-Day rate. ON the one hand this is a Naughty gaming of the system, but on the other hand, it makes any extra appliances used at the time exceptionally ‘grid friendly’.

As far as a CHEAP next to no cost EVSE installation, check out my year old video:

Loved the video Bill! The soundtrack (we are old), the commentary, the unedited camera shots especially on the bike. Some may not be aware how fortunate IEVs is to have your regular electrical input. From an electrician point of view, few are your equal. Owning both a Tesla Roadster and a Chevy Volt along with generators and now solar panels makes me take time to read all of your comments relating to electricity. I will agree that the smart grid is more about benefiting the utility than the individual, but I am still interested in a model that keeps them in the game long term, while providing affordable energy to everyone including what some would consider an unfair break to solar generators. As an EV/PV owner myself I am hoping for a long term relation with utilities but am preparing for going it alone if necessary. Some think that means proper battery storage only, but it will also mean a reasonable generator if you plan on cutting the chord. I really don’t want to do that, but am prepared to do it if the utilities do not play fair. Our co-op has already installed the smart meters. They really have… Read more »

M thanks for the kind words!

Next time I’ll script it because it has too many word whiskers doing it off the cuff. It was the first time I ever used a video camera.

Song choices are difficult because YouTube (Google) blocks anything it thinks might be remotely copywrited.

I chose “Mule Walk” when I was stumbling in the back yard.
“An Old Fashioned Love” when looking at my ancient electric panels.
“Harlem Hocha”, and “After You’ve Gone” in the Garage.
“September Song” during my October Bike ride.

These time of use rate plans offer great electric prices during off peak and super off peak times but many of the utilities here in Virginia also increase the Cost of electricity during the Peak time periods.

Yes, exactly. The goal is to get you to change your behavior so they don’t have to install expensive peaker plants.

You misunderstood my comment. My daughters electric company sells electricity flat rate at 11 C/kwh. they offered her TOU at night of 7 C/kwh then jacked up the peak summer rate to 33 c/kwh. Not interested in turning off the A/C and cooking dinner at 11 pm just to keep the electric bill below $300 when she can do nothing different and pay 1/3 less. Its stupid. A BEV does not draw enough electricity to covet the whopping cost increases. Its cheaper to pay flat rate and charge the EV at 2 am like she does now.

Some redundancy here since most EVs also have scheduled charging, etc., onboard.

But one key benefit for EVSE control is the ability for Utilities to make adjustments accounting for grid loads. However the only case I would consider Utility EVSE control is if the Utility supplies the unit and a corresponding rate plan. Otherwise, hands off!

I’m glad utilities, utility equipment companies, and EV companies are getting together and doing such projects & publishing the results. There are a lot of brain dead myths out there that need to be killed such as:
-Lots of EVs will require a massive expansion of the grid
-Having an EV will cause your electricity bill to soar
-Lots of EVs will cause electricity prices to rise
-Lots of EVs will cause brown-outs.

Just need limited amount of grid upgrading and time-of-use metering to encourage people to charge up at night.

I’m just proud something concerning EVs happened here in Kentucky. This is not an EV friendly state. With the exception of a handful of Teslas and Volts running around Louisville, seeing another EV is a rare occasion. Kentucky already has one of the lowest electricity rates in the country, so it’s great they are taking an interest here with EV adoption even if it is on a tiny scale. Even more surprising that they teamed with Ford. Dealership salesmen here run away when you mention an electric car. I bought my FFE in Ohio 🙂

I have to agree, energy rates are definitely low in KY. And I also had to buy my leaf “across the river” since I couldn’t get one here!

Well, sadly your EVs in Kentucky are not very environmentally friendly due to all the coal used to generate that cheap power. 🙁

If they are on TVA power at their location in Kentucky, the grid will get better. TVA has shut down a number of coal plants, and I believe mostly converting to natural gas.

One problem at a time 😉 I’m sure it will be a long time before they stop using coal in KY. There isn’t an “environmental friendly” attitude here at all. Mostly pickup trucks and SUV country. If this state ever has any kind of EV tax breaks or subsidies it will most likely be later rather than sooner.

Kentuckians (and Kentucky bashers), pay attention:
That goes for West Virginia, too.

Thank you for awesome presentation David. Very informative. Wish this video was mandatory watching for all drivers 🙂

Great video!
1, it is more environmentally friendly than an SUV.
2, I did it to foster the technology. I’m aware it’s not a sound investment, but I’m betting on the future.

Seems more hallow PR for Ford, sucking down DoE money, but actually doing very little with the funds. 😛

“According to Siemens, if utilities were able to control the charging process, energy bills could be lowered up to 60% compared to standard rates.”
That’s only if the power companies pass the savings onto the consumers.

And we all know how concerned power companies are with lowering our bill… wink,wink.

Overkill of a very simple problem with a simple solution; randomly distributed charging intervals over non-peak hours(well known) with extreme temperature limits(high and low) added. Then EVs would charge randomly off peak thus leveling the load curve – no big exotic system needed.

Well I watched the video, of which I liked the first half better than the last…..

Everybody here knows my favorite ‘fuel’ is coal, but, as you say, it is under 3% of an ‘option’ in NY State, and being mandated out of existence. So its not an issue in the states – much of it, I’m sure the Coal Miner’s who desire to keep working, are glad that their coal is more and more substantially shipped to Europe (to mitigate their issues with Russian and Gasprom currently), and China.

Personally, I avoid almost all Utility issues and take control by generating, in effect, over 100% of my usage with 38 solar panels.

So, what do you tell Floridians who

1). Have exhorbitant ‘connection fees’ to FPL.
2). It is illegal to be ‘stand alone’ in Florida. You must pay 1).

I’m told the only Solar Panels in existance in Florida are the Solar Generation for FPL itself.

Fortunately, the Sun is so lousy where I am, that solar power isn’t that compelling. The utilities here therefore don’t see it as much of a threat.

I read your North Caroline info flyer on the state of Florida, and see that the maximum ‘net metering’ is 2000 kw, but it doesn’t tell me what the “connection fee ” will be. I’m under the impression they set it so high that few use it.
