EDITOR’S NOTE: This is a sponsored post from Jedlix. A Dutch version of this article is below the English version. 

In a few years, the rest of the world will follow the standard set by Tesla drivers: they will make the switch to an electric vehicle. No more emissions, everyone will simply charge their vehicle when they come home at night, or during the day while they are working. There is just one problem: if everyone starts charging at the same time, the grid will not be able to comply with this peak in demand. Jedlix found the solution, it’s called Smart Charging – an ‘over-the-air’ charging solution that ensures your Tesla gets charged on moments when there is enough renewable energy available on the grid for the lowest price. The best part: you receive a financial reward for each Smart Charging session.

In 2016, Tesla became partner of Jedlix. Through this partnership, Tesla drivers are able to smart charge their Tesla via the Jedlix app.

An example, when you come home at night and decide to charge your Tesla, you might not need it again until the next morning. All you have to do is set your departure time and the app takes care of everything else. Via connected-car technology, Jedlix is able to communicate with your Tesla. Based on your departure time, battery status and the availability of renewable energy, the app creates a unique algorithm that calculates the optimal charging moments and ensures your Tesla is fully charged when you need it.

Smart Charging is easy

To start Smart Charging, you need to create a Jedlix account. You fill in your name, address and type of Tesla. Once these steps are done, we ask you for your Tesla credentials. Because of the close partnership Jedlix has with Tesla, Jedlix is able to make direct contact with a Tesla, but only with the permission from the owner. When a user logs in with their Tesla credentials, Jedlix receives a token from the Tesla API. Jedlix encrypts this token and saves it. This token acts as a key that Jedlix uses to connect with your Tesla. You do not need to worry about security, as we only save the token, not the credentials. Once your Jedlix account is set up, you fill in your energy contract and your preferred departure time and you are ready for your first Smart Charging session with Jedlix! Just make sure to check the app once in a while to redeem your savings. Savings can be redeemed from EUR 5.

“Jedlix charges my Tesla when green energy is generated, in this case I contribute to the most effective use of green power. The financial reward is a nice extra.”

– Wout van der Heijden, Tesla Model S owner

Binnen een paar jaar zal de rest van de wereld het voorbeeld van Tesla-rijders volgen: iedereen zal switchen naar een volledig elektrisch voertuig. Weg met emissies! Heel Nederland zal dan ’s nachts de auto thuis opladen, of overdag op het werk. Toch blijft er één hardnekkig probleem: als iedereen op hetzelfde moment begint met laden, piekt de vraag naar (groene) stroom. Het energienetwerk kan dat niet zomaar opvangen. Gelukkig heeft Jedlix heeft de oplossing: Slim laden, een ‘over-the-air’ laadoplossing die ervoor zorgt dat jouw Tesla wordt opgeladen op groene en goedkope momenten.

Sinds 2016 heeft Jedlix een partnerschap met Tesla. Dankzij deze samenwerking kun jij je Tesla slim opladen met de Jedlix-app. Slim laden zorgt dat je Tesla alleen wordt opgeladen op momenten dat er genoeg (groene) stroom aanwezig is op het energienet. Die optimalisatie zorgt voor lagere energieprijzen. En het grootste voordeel: omdat je helpt het energienet te balanceren, ontvang je een financiële bonus voor iedere slimme laadsessie.

Hoe Slim laden precies werkt? Stel, je komt ’s avonds thuis en je hangt je Tesla aan de stroom. Het enige wat je dan nog hoeft te doen is je vertrektijd instellen in de Jedlix-app. De rest gaat vanzelf. Via connected car-technologie communiceert Jedlix met jouw Tesla. Het unieke algoritme berekent de optimale laadmomenten op basis van je ingestelde vertrektijd, de status van je batterij, en de beschikbaarheid van duurzame energie. Zodra jij weer op weg moet, is je Tesla volledig opgeladen met duurzame en voordelige energie.

Beginnen met Slim laden is simpel

Om te beginnen met Slim laden heb je een Jedlix-account nodig die je eenvoudig aanmaakt in de app. Vul daarvoor je naam, adres, en het type van je Tesla in. Daarna wordt er gevraagd om in te loggen met je Tesla-credentials. Dankzij de nauwe samenwerking met Tesla kan Jedlix direct contact maken met je voertuig, maar uiteraard alleen met jouw toestemming.

Zodra je inlogt met je Tesla-gegevens, ontvangt Jedlix een token van de Tesla API. Die token versleutelen en wordt bewaard om verbinding te kunnen maken met je voertuig. Je logingegevens worden niet opgeslagen, dus over de veiligheid hoef je je geen zorgen te maken.

Voeg tot slot de details van je energiecontract toe en stel je vertrektijd in, dan kan je eerste slimme laadsessie met Jedlix beginnen! Check daarna af en toe de app om je bonus te claimen. Dat kan al zodra je 5 euro hebt opgespaard.

“Jedlix laadt mijn Tesla op wanneer er duurzame energie wordt opgewekt. Zo draag ik bij aan het meest effectieve gebruik van groene stroom. De financiële bonus is een fijn extraatje.”

– Wout van der Heijden, eigenaar van een Tesla Model S

What is it these days that there is no way to manage your account via a website? It is so freaking annoying to have to create an account via an app, generate a app specific password that I also want to store in a password manager.

Besides that, the user registration fails on the email verification where clicking on the validation link results in the response "
Cannot GET /email-verified".

Somehow the email got verified but I had to go all the way back and login regularly but because I didn't have the password stored in the password manager I had to reset my password. This procedure luckily IS possible via a website so I could use my password manager too to generate a new random password....
 
Now I have configured my car in the app and it really isn't obvious at all what my gain could be.

For example, I would always be charging at home (ABC) to for example 50%, above that I only want to charge if I actually have a decent discount or rate. I usually have enough energy to travel to most places.
 
I sure like the idea of soaking up excess clean energy that would otherwise be wasted/curtailed but I'm really skeptical that this app/company has a clue how to make that happen.

I'd love to be convinced otherwise.

There are lots of pilot schemes live, right now, in Europe, and often they feed their results directly into Government policy. The know-how gets spread widely and fast.

The Netherlands (where they are based) is probably the second-most BEV intensive vehicle market in the world after Norway. It is less than 5% the size of the USA, but has sold about 10 to 20 times as many I-Paces, for example.

I'm guessing if anyone has an informed view of how it can be done, it's a charging services company in the Netherlands.

The key next steps are adding V2G capability to CCS and Tesla vehicles. (The chargeport of world's best-selling BEV - ChadeMo - already has V2G).
 
Glad to see others tackle the problem of departure-time smart charging. Looks similar in functionality to the Smart Charging that's been a feature in the app, Dashboard for Tesla.

My suggestion would be to keep going - add an option to start HVAC near departure time, an option for changing the charge limit, and an option to maintain multiple smart charging schedules (think 1 for the week days and 1 for the weekends).
 
I use the service in the Netherlands and I have to say it works pretty neat. There is also a Dutch thread on this forum where we deal with feedback and suggestions.

On average I receive about 15 Euro's per month from providing the flexibility to Jedlix. It would be great if they would further pump up these numbers when more solar and wind flood the grid!

I did not get it. My car as most other cars still need to be charged at night time anyway. Not in a morning, not in day time, not in an evening. So, most cars have to be charged at night time, and night time is not that long, say form midnight to 6 o'clock.

6 hours of charging at 32A, even being extremely conservative with charging efficiency, is 36.9kWh of charge into the battery.

That's a lot of driving, far more than most people need. That implies that there's plenty of spare time in which to charge the car. So the cars can be used as a production-response or demand-response system, that can match charging with electricity production or other demand.

If BEVs are very successfully, we'll need smart charging to avoid excessive simultaneous charging.

In Europe most people have 3 phase charging possibilities, so 6 hours at 3x32A will fill up any Tesla over here.

Some cars arrive home at 5, some at 7, some at midnight.
Some cars need to leave at 6am, some at 8am.
Some cars need to replenish 200 miles of range, some need 100 miles, some need 30.
Many will vary from day to day, some will vary occasionally.
All in all, it's best left to groups of cars to arrange between themselves.
 
I got to agree with @SageBrush . The Western Grid, which covers Colorado, California and Arizona, among others, only gets 5% of its power from wind (and less from solar). I'm guessing, the best one could hope for, is to charge their car at 6ish percent wind when they charge overnight -- by timing it just right. I'm doubting the differences between the peak winds and the low winds, at around 1% of the generator mix, can generate a lot of 'payments' to share with those who charge overnight.

On the other hand, Texas has 10% wind generation in the mix of generators (using July 2018 data), and presumably, during the 'low demand' times around midnight to 3AM, that wind generation would creep up to 20% of the production mix. I know wind generation is where all the newly constructed generation is coming from in the next 2-3 years ... so maybe there is some hope for this in Texas.

For grins, I took a look at the New England grid operator snapshot of renewable use at 12:30AM (presumably a peak time in wind as a % of generation). At that moment it was around 10% (other renewables making about another 8%)... so maybe a well timed charge could find the peaks and avoid the troughs in wind there, and make a difference.

In The Netherlands in 2030 around 70% of our electricity will come from renewable energy - mainly scheduled and already being build offshore wind, the rest onshore wind, solar and biomass. You will understand the interest of Dutch grid operators into this kind of experiments in demand response systems :)
If we do this right than electric vehicles and variable - renewable energy can reinforce each other.

For sure.
Even today in California and Colorado it is frequent that clean energy sources are curtailed*. The problem is that a system that directs excess energy to on-call sinks does not exist today, and it is a lot more complicated than today's "smart" meters which really are only able to count in time slices. We need power electronics that can respond to utility signals saying when clean energy is being wasted. Also keep in mind that a majority of consumers really only care when energy is cheap, which may be clean energy -- or not.

*Curtailment itself occurs in the US because energy source mix is prioritized by cost without any pollution consideration.

Wrt electric vehicles I still expect a lot of the new ISO15118 protocol that allows the car to communicate directly to the EVSE (the charge equipment) about charging schedules, payments etc.
For proper smart charging the backoffice needs to know 1) total battery size 2) current SoC and 3) time of departure (ToD)
Jedlix (and also others that offer this service) are currently using a big detour: to talk to the car they are dependent on the manufacturers API, but to get the user preferences (minimum required SoC, ToD) they have to use a smartphone app.
Once the car and charger can exchange and negotiate this info and charge schedules directly adoption will grow imo.

EV charging:
- lots of spare time
- high level of predictability
- increasing proportion of electricity demand
- car has Internet connectivity

Renewables:
- variable but
- predictable over a 24 hour period

Conventional generation:
- dispatchable

You don't need smart power electronics to make a big difference. You just need to communicate an initial plan, and then make adjustments from there. A connected car should be able to receive communications and respond in under a second. It's a software problem.

I did not say all people would charge all 6 hours. What I meant is that those who have cheaper rate t night time will charge within that period which is usually between midnight and 6-8AM. So these people even with 1-2 hours charge will create big load in relatively short period of time, which is what we do not want (the goal is spread the load over 24 hours I guess).
 
Thank you all for the comments. Happy to respond to some of your questions and suggestions as an employee of Jedlix and big fan of this forum:

-We are planning to serve more European countries very soon. We do this for other car brands as well. The Renault-Nissan-Mitsubishi alliance is actually an investor in our company. Please shoot a mail at [email protected] if you are interested.
-Within our solution mobility comes always first. If you have to charge all need or first want the car to be charged to a minimum level we will always do this. In practice we notice that most customers charge at 11 kW and on average we notice something like 20 - 25 kWh per charging session which is about 2 hours of charging.
-When an area has only a few % wind/solar energy it is hard to talk about of surplus renewable energy which we put in the car. However we can still help the TSO/ISO to balance the grid and provide a financial reward towards the driver. Helping the integrating of renewable energy and the value which comes along with this is obviously higher when renewable energy gets to higher levels.
-We also serve connected charging stations. We apply this mostly in the public domain for now, but these could also occur at someone's home. Helping surplus solar energy (like in California) during the day is probably best done at charging stations at work or other public sites you charge during the day.

Thanks and let me know if you have any more detailed questions!
