EverCharge & Schneider Electric Partner To Deliver Multi-Tenant Charging Solutions

January 23rd, 2016 by  

Installing and managing electric vehicle (EV) charging for multi-tenant buildings continues to be an opportunity. A new global collaboration between two giants in the industry — Schneider Electric and EverCharge — aims directly at that pain point. The collaboration bundles Schneider Electric’s mastery in energy management and automation with EverCharge’s intelligent, scalable, fully managed electric vehicle (EV) charging solutions to develop a newer, smarter solution, and from what has been revealed so far, it looks promising.

Pierre Sacré, director of Electric Vehicle Solutions at Schneider Electric North America, shares:

“With most charging done at home and rapid urbanization happening globally, having EV charging in apartments and condominiums is critical to the continued success of EV adoption. This collaborative solution effectively resolves building concerns and challenges with smart energy management and automation capabilities.”

The specific opportunity takes the Schneider Electric EVlink Home EV Charger with EverCharge’s SmartPower technology to solve the challenge. Intriguing, but not enough to close the sale. The press release breaks out the exciting details:

“With this collaboration, EverCharge will integrate schneider_evlinkSchneider Electric’s EVlink™ Home EV Charger with EverCharge’s SmartPower™ technology, which can rapidly charge multiple vehicles and increase building charging capacity up to ten times without requiring costly infrastructure upgrades. When SmartPower senses extra power is available or that the rated capacity is reached, the system allocates power to vehicles according to their needs, maximizing building infrastructure usage while reducing deployment costs. In addition to the integration of each company’s technology, Schneider Electric will also work with EverCharge to expand its customer base to markets outside of the US.”

Many people don’t realize how much of an impact adding an EV can have on the load put on infrastructure. For my home here in California, each of our EVs use as much power per day as our house, so adding 2 EVs tripled our electricity consumption (which we then offset with solar). In a single-family home, that is usually manageable, but scale that up to a multi-tenant building and the increase in energy usage in a much smaller real estate footprint can quickly spiral out of control.

Applying the proposed solution to a multi-tenant building means that the EverCharge / Schneider Electric system will dynamically maximize the amount of power being pushed to the EVs in the network, without requiring incremental utility-scale infrastructure (such as transformers, transmission lines, service lines, etc). In many multi-tenant buildings, this can be the key differentiator that gets the project a green light.

In a curious twist to the news, the official blog post announcing this new development includes a picture of a Tesla charging. I reached out to EverCharge about the image and found that it was not just a strange coincidence but that there’s more to the story:

“We actually provide two kinds of charging cables, the standard J1772 or a tesla plug if our member requests one.”

The decision to add Tesla charging to multi-tenant buildings is great news. With the Tesla Model 3 on the horizon, Tesla Model S CPO prices dropping, and more people moving back to city centers, one would expect to start seeing more Teslas looking for overnight charging in multi-tenant dwellings.

    We live in an apartment & average only 240 kWh per month over the last year, including the high consumption from our AC in the summer. Our EVs use an average of 400 kWh per month over the last year. During the months where we are not using the AC we average only 133 kWh per month. Our EVs are not metered to us, but rather the electricity is paid by our apartment complex & we then pay them a flat monthly rate. Our EV kWh consumption would be triple our apartment consumption during fall-spring, or a fourfold increase in total consumption for the household.

  • sjc_1

    If the companies take all the expense and just charge a monthly and per unit fee, it could be a winner. The companies make money, the driver saves money…I like it.

  • JanVyt

    What is meant by Tesla plug? Type 2 connector?

  • evfan

    I wonder about this statement … “adding 2 EVs tripled our electricity consumption”

    Even a small household in California would use 500 kWh per month. We use almost double that. And in summer way more when it gets hot. Our EV uses about 250 kWh per month.

    What are you doing differently from us? Are you perhaps confusing power and energy?

    • It depends on what functions in the house are done using natural gas and whether standard efficiency measures have been taken like LED lights and reduction of vampire loads. In a CA house with cooking, drying, water and space heat done by natural gas, after efficiency measures, it is easy to hit 300 kWh per month for a family of 4. This is also the energy consumed by an EV to go 1000 miles per month which seems to be the average. So Kyle is probably right. As you keep switching natural gas appliances with electric ones which we should all do ultimately, the monthly kWh usage goes up substantially. I have an all-electric house now. Before it was 300 kWh per month. Now it is 500 kWh in the lowest months and almost 1400 kWh in peak of winter. The EVs are 300 kWh per month average. The EVs also consume more in winter due to cabin heat and battery conditioning heat.

      • evfan

        Indra … If I read correctly, it seems your usage is 500 kWh on your lowest month and 1400 kWh at your highest, hence your home consumes on average more than 2 EVs.

        It seems to me you might be fortunate to live in a place that does not need AC in summer. That means your life is different from most Californians. And basically, you have no idea if Kyle’s thesis is correct or not. Let’s wait for his response.

        BTW, what is the value of wild speculation about a mythical 300kWh per month house, when you can easily get real numbers on the internet, for instance did you know that on average US homes consume 911 kWh of electricity each month?

        • My house is all electric and not a typical CA house which uses natural gas for heating and hot water. Kyle lives in Southern CA. His energy usage he presented in an earlier article here:

          http://cleantechnica.com/2015/11/13/evs-pvs-driving-sunshine/

          I know the US homes data – US is not a model for electricity efficiency. For that we have to look at Western Europe – especially Germany. The 300 kWh is not wild speculation. I have consulted on energy efficiency here is the Bay area and I have seen many people achieve that number once they do the few efficiency tricks. It is true AC use is limited here but so is the case of Kyle and thus the numbers pan out.

          • evfan

            This is an article about two companies trying to improve matters in multi-tenant housing and all you have to add is “US is not a model for efficiency” and “my house is atypical”.

            Really??

          • Kyle Field

            @indradeep_ghosh:disqus – thanks for pulling the detail from my previous article where I expanded on my usage details.

            Specifically, the 6 months prior to purchasing our first EV, my total home usage was ~7.7kwh/day. We do live in an area where AC is not typically needed and in fact, we do not have an AC unit for our home. Out big electricity hog for the house is our electric dryer which pulls tons of power on laundry days.

            Comparatively, our first 12 months of ownership of our Mercedes B-Class Electric, we used 9.6 kWh/day though not all of this was out our home as we explored public charging, range of the car, etc. Finally, the first five months of ownership of our Nissan Leaf (EV #2), we used 7.9kWh/day of power.

            The net change was just over triple the usage vs our baseline usage. As you noted, this is not the case for everyone in the US but is a major increase that many people might not be expecting (even though it is fully offset by gasoline savings)

          • evfan

            Kyle – thanks for explaining this. It is remarkable that you are able to run a house with 7.7kWh/day, which is worthy of a separate conversation, and something that many folks (including me) could learn from.

            Mentioning this fact without context in an article about multitenant charging confused me personally more than it helped.

            BTW, did you realize that your economic lifestyle leaves surplus capacity on the infrastructure and made it easier for the grid to support charging of your EVs?

          • Kyle Field

            My personal usage example was intended to show the massive incremental load to the existing infrastructure. Overall building usage is, let’s say 8000 kWh/day for 1000 units and 10% of those users add EVs, that’s a potential (again, using rough math) 800 kWh/day of usage that the current infrastructure may not be able to handle. I’ll work on positioning my points better in future articles 🙂
            About the lifestyle leaving extra capacity on the grid…yeah 🙂 My goal is to be a net generator whether I am reimbursed or not. It’s about sending a message that it’s possible…making your own power, driving on sunshine and being a net producer 🙂

          • Otis11

            Keep in mind that much of that charging will occur over night when the infrastructure is not being challenged. (or, if at work, during the day when solar should soon handle it locally – but that might be my optimism showing through.)

            As long as charging doesn’t significantly overlap with the 2 hour morning or 5 hour evening peak, we have 18 hours of the day with overhead – I’m sure we can find 6-8 hours of time with surplus grid power that coincides…

          • eveee

            Yep. Only if everyone gets a level 2 charger and charges at high rates will there be a problem. Level 1 is only about 1kw.

          • Otis11

            Actually, level 2 charging with a smart charger would be better… instead of the grid seeing a constant demand as everyone’s car is charging at 1kw (but needs to charge for 8 is hours) the grid will see up to a 6kw draw from each car, but since those cars can now be charged in less than 2 hours, they can be shifted to the times when there is excess power on the grid (most likely wind as that’s the only one that would be fluctuating).

            This can help demand meet supply and lower the cost of grid storage, increase the revenue going to wind (by keeping wholesale prices level during periods of wind production) and still get everyone charged by morning!

          • eveee

            Totally. Smart chargers could figure out they don’t need to charge fast. They could also evaluate when charging is happening and when the car is needed, so that charging is the lowest draw and cost.

          • Kyle Field

            Ah, but if we have 1X load during the day and 2X load during the night…peak will start to shift to nighttime…when we don’t have solar. Wind and storage will help but it is creating a shift…or will create a massive shift in peak loads.

          • Bob_Wallace

            With smart charging we can spread charging and not load up the system at any one point in time.

            We need to get away from peaks in demand that send us looking for more supply and start moving demand to match supply.

          • Kyle Field

            I fully agree but it will take time for those signals to play nice across the full system. It’s currently just a common charging grid with flat rates at fixed period of the day. Having flexible, hourly rates based on the actual cost of generation would help but we still have a ways to go to get there. The collaboration between EverCharge and Schneider is a good step in the right direction but still just an early solution.

          • Bob_Wallace

            We’re in the very early days of EVs. We’ve got time to evolve charging.

          • Kyle Field

            In principle, I agree. The issue is that it is holding up adoption and creates bad experiences for buyers who try to use the broken L2 and L3 DCFC infrastructure. I noticed a HUGE difference when I bought the Tesla and can say that I no longer have range anxiety. I know there will be a charger for me. In fact, I can check availability of superchargers before I get there (allegedly at least…haven’t tried it yet).

            Also, the faster the charging time, the less total stations we need which is a key distinction. For example, gas stations offer fill ups in ~5 minutes for ~300 miles range (ish). Superchargers take 30 minutes to add 170 miles. If we can cut that time in half, we can crank through roughly twice as many charging sessions per station. It’s not completely linear but you get the point.

          • eveee

            It depends on if its level 1 or level 2 charging. No way level 1 is going to stress the system. But even level 2 won’t stress the system unless you are charging at the max NEMA rates, 240V @ 50A. Then it could matter. But not everyone is going to overnight charge their vehicle in 2 hours. And the rate of charging is lower when the battery is not fully discharged. So if the average user is driving 30 miles a day, they probably use about 10kwhr a day. If they charge at night, they need only charge in 10 hours, only 1kwhr per hour, 1kw. If an apartment were filled with Teslas driving 100 miles a day, with their beefy 60A+ chargers, that would be a problem. 🙂

          • Kyle Field

            Exactly 🙂

          • Kyle there are some heat pump dryers currently available in the market which will cut your dryer energy consumption in half at the expense of 30 more mins per load. Here is one model but there are others too:

            http://www.lg.com/us/dryers/lg-DLHX4072V-electric-dryer

            This is on my wishlist but right now since I am still running net positive energy there is no incentive. I will wait for the current inefficient one to die.

          • eveee

            Kyle- I’m jealous. 7.7kwhr/day x 30 days/month = 230kwhr/month. Thats incredible. I get about 500kwhr/month, maybe as low as 400 if I am lucky. The average is higher. Many people have 1000kwhr/month and up. You really are not driving that much daily, at about 3 to 4 miles/kwhr, you are only going 20 to 30 miles a day. So I don’t think its true that the average person will double their electric usage. That said, anyone in CA not on an EV rate is going to pay heavily for dipping into tier 3 or tier 4 pricing.
            There is nowhere in the US with an average electric consumption rate that low. So the average US consumer might increase their electric consumption by 20 to 50% at most.
            Average US electric consumption is 911kwhr/month, about 30kwhr/day.

            BTW – Just a note you might be interested in – condenser clothes dryers are about twice as efficient as normal vented models (like the one it sounds like you use), and they’re reasonably affordable! You can get a washer/dryer combo for $1,200-2,000 depending on features. Here’s one I’ve been looking at: http://www.lg.com/us/washer-dryer-combos/lg-WM3477HS-washer-dryer-combo

            (Though, I actually just hang dry everything but my jeans and towels as they’re simply too thick to dry effectively… or I’m just too impatient)
