At the 2015 SAE World Congress, Siemens introduced its VersiCharge SG, a wi-fi enabled, cloud-based electric car charging station for at-home use.

Here are some highlights of VersiCharge SG:

  • New VersiCharge SG gives consumers the ability to monitor and control a charger in real-time via a mobile or web-based app on the cloud
  • Can interact with utility programs like demand response directly through the cloud, allowing utilities to better understand electric vehicle usage and lowering costs for users
  • Technology has shown to result in 45 percent lower charging costs during off-peak hours compared to traditional electric vehicle chargers

We don’t yet know pricing for this new wi-fi enable unit, but the standard (non-connected) VerisCharge goes for $649.

The VersiCharge SG will be available for purchase in late 2015.

Siemens Introduces VersiCharge™ SG, the First Wi-Fi-Enabled, Cloud-Based Electric Vehicle Charging Station for Residential Use

New VersiCharge SG gives consumers the ability to monitor and control a charger in real-time via a mobile or web-based app on the cloud

Technology has shown to result in 45 percent lower charging costs during off-peak hours compared to traditional electric vehicle chargers

DETROIT–(BUSINESS WIRE)–Siemens introduces VersiCharge Smartgrid (SG), the first Wi-Fi enabled electric vehicle (EV) charging station that allows residential owners to monitor and control usage remotely through a mobile or web app. With this new technology an EV owner can automatically turn charging on or off, schedule charging when rates are lowest, and view past power consumption data including usage and cost for the first time in a graphical form. The cloud-based charging station also interacts with utilities, receiving demand response and pricing signals so consumer can better shape and shift their charging experience. Utilities can 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. This level of interaction will enable utilities to better understand the impact EVs have on power consumption market and will result in lower charging costs for the consumer.

“The VersiCharge SG solves two of the longest-lasting challenges associated with EV ownership—the uncertainty around the actual power being consumed and the ability to easily control energy consumption”

“The VersiCharge SG solves two of the longest-lasting challenges associated with EV ownership—the uncertainty around the actual power being consumed and the ability to easily control energy consumption,” said Barry Powell, head of Siemens Low Voltage & Products. “Consumers can now have flexible charging options that can target either the cheapest energy rates or instant convenience and utility partners can better understand the growing network of EVs and their impact on the power grid.”

By 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 or rate at which kilowatt hours are supplied to the EV, utilities can potentially reduce the peak demand on the grid, which in turn helps to reduce the total amount of generation needed. When the demand response functionality is enabled in the VersiCharge SG unit via the mobile or web-based app, utilities and energy aggregators have new opportunities to use EV technology as a valuable part of a distributed energy management strategy.

The VersiCharge SG can be installed for indoor or outdoor use via a plug-in option or hardwire installation. Siemens also offers an accessory pedestal that allows users to install units in locations where a wall mount is not possible.

The VersiCharge SG is part of Siemens VersiCharge electric vehicle charging portfolio and offers the functionality that has been incorporated into the VersiCharge line of level 2 electric vehicle chargers since 2012: 30 Amps of charge at up to 7.2 kW charging rate with the standard J1772 connector interoperable with most EVs, the highest degree of safety with UL certification, best in class outdoor rating (NEMA 4), and best-in-class 5mA CCID ground fault protection.

The VersiCharge SG will be available for purchase later this year. To learn more about VersiCharge SG, please visit Siemens Booth #426 at SAE World Congress in Detroit.

Since the network functionality is more targeted at helping the utilities, I hope they will offer incentives to make this unit very affordable.

Vehicle manufacturers can’t seem to get the scheduler/control interface right, so putting this type of network control in the EVSE is a no brainer.

Hopefully they won’t make the same mistakes (need at least multiple schedules support, multiple types such as start and end-by time, charge to certain SoC %, on/off control).

Good point. Every utility should have a incentive program to help pay for charger installs since it:
1) Gets them users of additional electricity.
2) These users of additional electricity are the best type since they will largely use excess electricity available at night.
3) The incentive program the utility to choose the charger that will be installed.

And that’s why Evs will, hopefully, change the world. Imagine a few million EVs capable of using all those GWh that no one wants. Just how much would those EVs facilitate the penetration by renewables?

Nice to see Charger makers adding these features. Every charger should have them. I wish my very nice but pretty dumb charger had some of these features. (Actually, my charger is pretty smart, but it lacks software/control that I can access.)

I am still waiting for the EVSE that can inter operate with by Solar Energy Monitoring (eGauge in my case) – give me the option to charge only using available Solar, or option to make sure charging is complete by a certain time using Solar plus grid.

I wonder if this one would at least give the option to remotely adjust the rate – ie charge at up to 7.2 KW or use some reduced rate all the way down to 1KW. I do this manually now with my EVSEUpgrade Panasonic charger – specify anywhere from 6 to 20 Amps at 240 volt – so effective 1.44 KW up to 4.8 KW – anywhere in between in increments of 240 Watts. (Yes – I am a geek like that! 😉

Yeah, sad that many EVSE’s do not have this feature. After all, changing the duty cycle of a PWM is a free feature and takes only a few lines of code.

Bill Howland

That would be a good trick, getting a contactor to do modulation.

Conceivably though, you could ask the car to constantly renegotiate the charging speed, so that would kinda do what you want.

Bill Howland

I’m still waiting for Siemens and Eaton to coming out with their 70 amp models they both promised 4 years ago.

Wait, I forgot that the trend is to smaller charging docking stations. Guess that’s why those 2 companies don’t sell the 70’s yet.

And a slight correction: I’ve finally confirmed the highest GM charging J1772 rate is 15 amps, not 16 as I had erroneously assumed.
