- A rundown of a homemade evse level 2 EV charger with variable current charging capability. This is the beginning of a project i hope to expand on in the future if it sparks interest in enough people i will create a video series explaining how to make your own and release everything open source.
Congrats! Very nice EVSE. I was considering building my own Arduino based EVSE but eventually went the Open-EVSE route, mainly because of lack of time. Yours looks very good too. Keep up the good work!
Excellent video. Explains the charging process quite well. Thanks.
Finally! I've been looking for this particular video for a week now. This is encouraging. If you have a schematic video, I don't know yet, but this explanation was great!
Excellent introduction, looking forward to seeing the schematics and the Arduino code
Just wanted to say that it's awesome that you made this and are looking to help others. I'm still in the dreaming/research phase of getting an EV. I need a minimum 100 miles of real world (a/c or heat on) range or a Model S closer to half price to consider it.
I would be interested in developing my own EV charger. Do you have a list of parts/vendors and instructions on how to create one?
Bruno, the pcb's were just purchased on ebay. If you go on ebay and search for pcb manufacturing, you will find many services for sale and look for one that meets your requirements. I would highly recommend this over an expensive service if its just some small project your working on. You can buy them really cheap from china or a little more pricey to be made in USA.
Hey Jacob
I'm thinking of building my own level 3 dc fast charger for my final year engineering project.
Can you make a video on it and guide me, please.
Thank you
Excellent bro
very cool.I like your attitude. Keep up the good work.
Jacob, This is a really awesome project! I currently have a 3.3kWh charger and would like to move up to a 6.6 kWh charger. I'd love to build a charger that had a timer so that it only charged to 80%. This project rocks! Ready to start when you are.
I would be interested in developing my own EV charger. Do you have a list of parts/vendors and instructions on how to create one?
of course I'm interested! I'm riveted and would love to see your behind the scenes build and coding. I understand your time is valuable but I would love to build one similar even though I like the juicebox 40 there is nothing like doing it yourself for control and comprehension of the technology. Sorry to request you work more to show how you coded your arduino it's just really well done and I know I could not do this without some guidance, I don't mean to seem unappreciative of it. Thank you for making this video I am grateful
Please continue to make videos about this topic, I will be so thankful towards you sir. :)
This awesome a lot of good information! Great work!
I hope you carried on with this project. I would definitely be interested in buying from you.
Very nice project
Thank you
For a 30A draw you need a 40A circuit... running at 100% for the extended time a car charger draws will overheat the breaker. For a 30A breaker the max continuous draw is 24A.
Not just the breaker. He needs to run 8 gauge wire to pull 30 ams. As you state 24amp max.
Um no your wrong a 30A breaker will supply 30A all day every day because that's it's max continuous rating... also 10AWG or 6mm2 is the correct size cable too
@@rjac001 It will work, but it's against code. It's legal for a non continuous loads. But for continuous loads 3 hours or longer the 80% rule applies. 210.19(A)(1).
Jason Kates The circuit breaker is only there to protect the cable, the 10 gauge wire is rated at 32A continuously and so there’s no risk of damage or fire to the cable, also it’s a fast charger so I doubt it will be delivering maximum current for very long
@@rjac001 Have you looked up 210.19(A)(1). I agree it's likely to be very safe. It just doesn't make code.
Very nice!
And thanks for the great video!
It would be nice to be able to buy just the finished control board and then adding the other less sensitive components to it, like relays, power supply, etc. It would make building one of these chargers an order of magnitude easier.
very nice and informative.
nice job! love to figure things like this out,but in nursing school so busy busy I would like to put one with a plug into 220 outlet Campground etc
michael patterson my 2014 Smart has the same ESVE. I've been running it on 240 volts. Same with my Chevy Volt. I think they built them 120/240 for USA/Europe/Asia. I just made a 120 to 240 adapter.
Awesome! Subbed!
Hi Jacob .... very well done video, long time back I used to do projects with micro-controllers, this was a good refresher. I bought prius prime and it came with a 110V cable. I saw another video on youtube where it says you use NEMA 10-30 to 5-20 converter and you can use same cable that came with Car to charge at 240V. Do you see any issues using it 110V cable that Toyota provided to use with 240V ? BTW have you assembled the PCB that you shoed towards the end?
thanks for the video
Great idea on open source. I see a Jordi Munoz or a Chris Anderson here. Who knows it can regulate the charging industry mate. Keep doing what you do and in future once you make a name for yourself,, you can just settle into a reliable hardware company like netgate does for pfsense. Keep up the good work and sure buddy you have got the brains to make your hobby work. Do post the project on RUclips so you will get a community.... I will be sure in it
Great video, great controller, especially the feature of regulating the charging current. Did you ever sell this kit ?
very impressive.
hey jacob - you should add a amp meter to the charger showing how much power the car is using - giving an indication on the battery charge level without having to go into the car and check!? - also do you have solar on your roof? - it would be an awasome addition - even if you were to use some Ebay solar panels and the Ebay micro Grid Tie inverters - they work alright aslong as if its rated for 500w you only put 400w thru it!
Hello! Very nice video, everything well explained! It's been 5 year since you made the video. Do you still have this project traceback? I want to build one.Do you still have the data? Pcb file? Code line? Parts list?
Thank you in advance!
Hello Jacob, Thanks for the video. It is informative and helpful. I don't know if you have made any chargers or kits to sell but I would be interested. I like how you can vary the charge and how you built in those capabilities.
What is your budget and how many kw?
It a very good idea. I am interested to make my own EV Charging Station. Could you give me more detail about the component you used and the coding of Arduino. Thank you.
I need to make one!
Great job Jacob, I wonder if you can come up with a portable DC charger project.
very good job, i am interesting in making charger like that if you can help me with more details and diagram, i hope you have the time to help.awesome work
I'm thinking of getting my own 500e to zip around in and mod. I'll definitely be building one of these as part of that. Do you still have your 500e? Did you do anything else to it?
Hey Jacob,
I would be interested in developing my own EV charger. Do you have a list of parts/vendors and instructions on how to create one?
Thanks!
Love the video. Would love to chat. Have you built a bidirectional charger?
This will be great when you are combining 2 120v outlets and use one of these to regulate the current.
Awesome video. Just got a 2014 spark ev. I wonder what the max amps in 240volt charge mode my car would draw? As Im just learning the cars have onboard chargers that limit the max amp charge, so getting the biggest amp 240 charger might be a waste of money if your car won't use the power. But I'm looking to make my own charger and help others make there ev,s more affordable here in New Orleans its the oil mans land.
Where did you printed those prototype PCBs?
I'm looking for cheap places to try make my first PCB.
Thanks.
Set up a patreon and make this opensource. You could sell diy kits on ebay. One kit option could be just the arduino with sw, relays, pcb. Often DIYers have auto ranging 12V power supplies lying arround and the bulky heavy stuff can be sourced locally. Also using github allows collaboration and sw vetting and improvements. Kick starter is unnecessarily expensive. Use PayPal which gives buyer protection. OSH park does low volume pcb cheaply.
I would like to try and make the one you have on the PCB at the end of your video. Do you have the schematic or the board layout, I would get one made and start playing with it to learn more. Great video thanks
Hi. Nicely explained.
Is the PCB available to buy from you?? If so let me to know
looks really great .use the basic principle of the EV charger，but there maybe a issue about the TYPE B RCCB or something breaker for the safe，hope the upper level have that breaker. and i come from a EV charger company which form China.
Cool. Nice video. Learned a lot. How can I reach out to get one of kit?
Have you ever done a Solar Panel(s) to j1772? For portable charging applications.
I would really like to see all of the code and how to build one of these chargers in detail. Thank Jacob
Fantastic!!! PLEEEEEASE share schematics and code (if no code available, just the logic and values to input and output. Thanks!!!
Hi Jacob i m interested to know more about it like how to use this PCB board and build the components. or if you have a kit or if you have list of items that we have to solder on this PCB board.
Jacob, is this an AC charger or DC fast charger?fast forward to 2021..do u have Schematic diagram of your design? Can I use arduino uno?
excellent Job!!!!!!!!
Pls can you give me more info how to fix it ? I have an opel ampera and I need to make one charger!
you should make kits to sell with full hookup instructions
I'd LOVE to learn how to build an EV Charging module. When can we expect a vid that explains the process?
Recardo Poole I have been very busy recently with school but hope to get some new videos up soon. That video is on my list but will be a longer video to produce. subscribe to see it when it does come out. I hope to get started on it soon.
Curious why you didn’t go with a heavier duty solid state relay? How many amps are you drawing?
Jacob, I am a retired EE. The control panel lacks an interlock safety that can easily be part of your key lock like a lock/service and run (easily just a 12VDC shut off). I don't know if your software uses a sense circuit before it sends 240VDC to charge your FIAT 500 EV.
BTW, back in the late 60's I had a FIAT 600D 1.1 litre gas engine. It was a suicide car (backward opening doors, etc. The new FIAT 500s are a class above those FIATs.
There is no need for that as the relay never closes till the vehicle is connected. Because I built this charger for myself it wouldn't be necessary to add an interlock to shut off the power when the door is opened. The voltage is 240VAC not DC but that doesn't matter much. Why would an interlock be necessary?
Hi Jacob . Did you get any of these boards available to buy? I'd love one (or more than one!) Ideally populated with components and the chip already coded. I can build the rest. How can I reach you?
Hello sir, could you please tell me what ist the type of the power relay that you have used.
thanks in advance
Impressionnant. Un travail formidable. Même en kit a monter soit même, ca serait cool.
Futur proprio d'un Fiat 500e
Badass
Okay, this is way out in left field coming from a complete novice . I'm building a camper van to go cross country. I'm hoping to use a Tesla model 3 module (slab) as my house battery. Solar will likely not be able to keep up with my power needs.
What would it take to be able to use EV power station to top off my battery along the way.
Open source it. Then you could offer customers a range of choices from just the plans, to key parts, to a full kit, to a built unit.
Wonderful video, thank you for making it. You should make this open source.
So let me get this straight. I'm new to all of this. So the charger (AC to DC conversion) is really located in the car, why do they call the thing they call a charger for $500 to $1,000? Seems to me it's not a charger but a micro controller to control the amount of AC being delivered to the charger in the car.
When you refuse the current being delivered tot he batteries are you just cycling the power relay to reduce the amperage/wattage? If so, seems to me the relay contacts would burn out in no time.
Any idea why they did not put all of the charger circuitry into the car? So to charge it, all one would have to do is use an extension cord and plug into a 120vac or 220vac outlet?
I made a series of videos explaining how all that works in much greater detail and actually show how to make one. To limit current it is not the power relay but rather the charging unit in the car regulates the power electronics within it to decrease the current.
***** That makes sense. So what's the purpose of the external $500-$1,000 "charger" circuitry if the charger is already in the car?
Why not use a 120 v or 240 v extension cord to the charger in the car? What am I missing?
Can you provide the links to your videos? Thanks for making them.
I explain it in my first video about how to make the charger. My fit charger video has nothing but details about this charging standard and how it works. The primary purpose is to de-energize connectors until the car is ready to charge and also to tell the car how much power the specific charging station it is plugged into can supply.
Cool. Think I'll make one for my van and carry it in the back with a generator
Superb project I need the product prototype or if possible share the circuit for me in India
Awesome... I'm looking to buy a wallbox for my e-golf ...but this video might turnme towards DIY :P hmmm
Now we need to make CCS chargers for home
Have you made Video Series.
Although I watched this video lately but i think you're right
what i realised is that it's not a charger rather a monitor
i have a problem that I would like to ask you about
i bought a GE durastation level 2 charger 60hz and i took it outside to Jordan where the 240v are one phase and one neutral and not like it's in the states, also the hz is 50 not 60
it didn't work but i could test it to see the problem which was the hz thing.
I wonder if you could help me to convert the charger from 60hz to 50hz
thanks.
Sir can you put a detailed vedio about all its schematics and coding as quick as possible, please
Can you post the components/parts used? I would love to make one of these.
I would like to know if you are able to build a charging station that is solar powered. My idea is of solar panels and/or wind turbines that charge a battery bank. That battery bank can then be used to charge your electric car. This way an electric car owner can have their battery bank charged while they are at work during the day. When they get home they can transfer that stored electric power onto their car. Let me know.
J Bishop has got it right. I like your LCD Display, and controllable AMP's and Wattage. Please post a Website or Email for communication.
where do yoou install the Prox detection wire cause My dostar cable has a 5th wire as well as the control pilot.
Damion Litrel you should not have to hook up that wire all the proximity signaling is done between the car and the resistor network in the connector handle.
Isn't the charger itself actually in the car and this is simply a control circuit for the charger input?
Yes, its main job is to tell the car the max amperage of the supply circuit and to turn power on and off when the car asks.
hey ,
what happens if we use 120v instead of 230 v in these same circuit.
Will the car try to take 30A.
Remember we don't change anything in the circuit only the input voltage.
I'd be interested in learning more.. kit form ?
Hard 90 degree bend, right through the concrete?
really interresting! Can i have your arduino code, list of things and the circuit plan please?
hay jaacob,
i was also planing to make my charger, can you please upload a circuit diagram
Is it possible to make a fast charger and install it in home ?
Make a video on level 3 dc fast chargers.
most fast chargers are 300V-480V or 3-phase lower voltages. Not available at a house easily. You need lots of extra equipment beyond this.
@@edwardruiz8920 except that every solar system on every house produces power at 500v
@@chris2pherrea that's not true for microinverters or power optimizers. A typical central system varies from as little 250V up to 1000V on the DC side at a residence. The Tesla powerwall operates around 400V for the purposes of charging Tesla EV cars through solar sources. The output is usually single phase 240VAC.
@@edwardruiz8920 Right, but as I have the option to install a new system on my house as 25Kw, I can choose to make them 500v strings, and could them use them directly into the DC charge port of my leaf ??
Do you have a commercial project running on this or a later better design?Would you like one?My company is looking to get involved in the home market fast charge EV sector.Based in UK, but not a problem USA.Please advise status / interest.Thanks P Bentley MD
Would love to build one. Will keep monitoring, can I get the PCB layout so I can get board made? Thanks John
Sorry I no longer have the board layout files I made them many years ago but I recently made a series of videos on how to build one of these chargers.
What is the chip part number you used for the micro controller. Thanks
hey love the concept would really like to know how to put one together at home 😉👌
Hey ! I have a Dell Poweredge 2950 but sadly i dont have any harddrive trays. I was wondering if you could figure out the dimensions of the tray so i can print it off on a 3d printer. or, if you can could you make me a file so i can print it off ? Thanks !
Hello Jacob, I am very interested in learning more about your progress, I am in need of building a level two charger for my new Volt, I want to build an out door one at my apartment building. now can I contact you
where people like me can get instructions to build the charger I drive the same car but takes too long to charge it with the level 1 charger that comes with the car, please can you publish a guide online?
Any reason not to use solid state relay?
Very nice Project. I would like to buy from you the charger , if it's for sale. Just let me know and we have a deal. Thank you
What is the output
Have you uploaded the code anywhere?
Hey do you have any for sale yet interested in buying one from you.
Could I buy 15 boards from you?
"Hot phase"? thats a new one
What is the deal with the pilot pin? Is the vehicle controlling the charger? Or the other way around?
Steve Roberti it is sort of a two way communication. The car really controls the line and tells the charger what to do but the signals on the line tell the car how much current to draw and when it can charge. Watch my video series where I explain how I built this charger and I have an entire video explaining the pilot pin and the j1772 protocol.
Jacob Dykstra Thanks. I will check it out. I guess whatever the standard is it must be relatively simple if its all communicated on 1 wire.
Steve Roberti it is a very simple standard. It is all analog voltages and PWM no digital communication or data frames or anything like that.
Can we connect ..looking for ppl who could create such chargers . Can discuss in detail when we connect
Hello Jacob, is this channel still being monitored and responded to?
Would you make a dc charger?
Also, though that relay is rated for 30A, the QD terminals are not. Fortunately your car is not pulling a full 30A, but if it were, those QD terminals would overheat. I speak from experience.
+Nick Sayer It looks like he soldered and shrinkwrapped the connections, that should be good enough for 30 Amps!
+J Bishop Yeah, no. Been there, done that.
Nick Sayer If the relay is rated for 30 Amps how can the connections on the relay not be 30 A?
+J Bishop 30A in general does not mean 30A continuous current for an unlimited time. In general, unless the component specifically says that it's rated for 30A EVSE or continuous duty, you need to derate it by 20% when used for continuous duty service.
I haven't ever found QD terminals that work long-term at more than 24A. And even getting them to work at 24A requires using a ratcheting crimping tool, and using it *properly* and with very high quality terminals. The ones I use were something like 75¢ each in Q:100 from DigiKey. The crappy ones you get from Home Depot are no good. And you don't want to solder crimp terminals. Solder actually doesn't conduct nearly as well as copper does, and if you do the math, a resistance of a mere tenth of an ohm at 30A will dissipate 90W of power!
Nick Sayer I didn't know that either. Are you an engineer?
Have you done anymore with this project? I'd like to figure this out , however some of your terminology is over my head.:( However, if it is broke down I can put it together.
