DIY Level 2 EV Charger Part 1 - The J1772 Standard

A very detailed description of the J1772 standard. In this video I explain the information we need to know in order to design and build our own level 1 or level 2 EVSE.

[@ingeborgsvensson4896]

Great video Jacob, you explained it very well. The J1772 is actually the protocol which is used, and European EVs use a different plug (Mennekes) but the exact same J1772 protocol. My plug on the Renault Zoe has 5 big pins for 3 phase 240V AC charging and also the pilot and proximity pin, it does not have a button on top but the car latches onto the plug automatically so you cannot remove it during charging. I'm going to build one based on you design, the only difference is I use a 4 pole contractor/relay and the plug pinout is different. And since the Zoe is very fussy about the signal I will probably need the -12V but I can modify that. Thanks for the videos!

no

[@lassleering7403]

You're good! understanding and explaining are too different things. You're a great teacher.

[@TonyLehto]

Your ability to explain electronics is simply amazing.

[@randycarter2001]

The best description of the J1772 level 1 and level 2 charger it"s a "smart safety switch". It makes sure certain safety procedures are followed. It's all automatic so a user can't skip a connection step.

[@oariv]

I love the way you share your understanding.

[@oariv]

please do not be or feel discouraged from giving your viewers the deep intricate working of any device as I for certain have learnt from every one of your videos watched by me. God bless you and a sincere thank you.

[@pipe2496]

Great explanation of the diagram and thanks for explain in the end with the osiloscope and the resistors, this is the video that i was searching

[@Garageaholic]

Very interesting. Thought about building an EV car myself and plan to use this J1772 standard for sure.

[@user27108]

did you finish building the car or in process or stoped?

[@daniascov2175]

You are great, keep up doing this and come with new thinks that helps people to save money on overpriced stuff. Thank you for everything you do.

[@quinnmarc8230]

Not sure if anyone gives a shit but if you are stoned like me atm you can stream pretty much all of the latest movies on InstaFlixxer. Been binge watching with my gf during the lockdown :)

[@hezekiahturner5939]

@Quinn Marc Yea, have been watching on Instaflixxer for years myself :)

[@jonahalec1076]

@Quinn Marc Yea, been watching on InstaFlixxer for since december myself :D

[@raphaelbranson5832]

@Quinn Marc Yup, I've been watching on Instaflixxer for since november myself :)

[@Eximnos]

Excellent presentation!! thank u very much!! The document is very nice too.

[@rahulaggarwal288]

Please make a video on diode check

[@quickquote1568]

Excellent presentation. Thank you !

[@Balo1997]

Great video, I haven't finished it, but it has been very helpful.

[@Charlieporras1]

Great video! Thanks for this content! I’m gonna build my own!

[@olayiwolayusuff149]

I’m actually on a Project to build an electric charging station and I’ll love to talk to you directly on design calculations and some other stuffs I’ll need

[@healthytipsforu3759]

Very informative video, thanks for effort

[@olayiwolayusuff149]

I don’t know if I’ll need a step down transformer I generating the AC mains voltage , I’ll like to talk to you directly Jacob on how to go about it. I’m a Nigerian who studies Mechanical Engineering.

[@robertfeher3269]

Great instructional video. I have a 2017 Zero SR electric motorcycle. Can you make a tutorial on building a 3.3 or 6.6 kwh 220 volt level 2 onboard charger? Diginow makes them but they want over $3000.00 for their charging system. Any and all help would be greatly appreciated. Thank you.

[@Josef-K2]

Jacob, love it! I just messaged you regarding Charg Coin which I think would be an amazing fit for this. Hope to hear from you!

[@JohnCChou]

Great job, young man.

[@line10cls]

Excellent, very informative

[@MrTitocharly]

If I'm in Europe, and we use CCS charger, the vehicle controller is the same as J1772 ? It should be right? I don't wanna mess it up, that's why I'm doing this question. Thank you

[@MrKLyova]

Great job, THANK YOU!!!

[@abuzaaky]

I wish there was more than one like button!

[@emrahbozkurt67]

Why we use pwm low -12v? Can u explain in more detail?

[@dinu872004]

Perfect job thanks for the detail information

[@hastieyhameed5548]

Hi, if I buy a voltage converter “110 to 220” in an attempt to boost up the charging time when I plug my cord to it, what specifications should I look at when buying the product?

[@SebJames55]

This is spectacular!

[@sharlookhoolms]

that's awesome bro, thanks

[@electronicinduction4116]

If you want a power supply that can. Provide+/-12v with a common Ground a pc power supply would work as long as it's low current. Very cheap too

[@Yukuaimeiguoren]

Jason, level 1 charging cable broke when I ran my car over it. Don't ask me the details.. Is it safe to strip off the plastic covering to repair the wires and rewrap it with electrical tape? Or is it more involved? I have not had time to watch the whole video.

[@SuperAaronsun]

Hi Jacob, you are awesome, I love your video.

[@markus1962]

Do you think it would be possible to use dc directly from solar panels? And modulate duty cycle for max power point?

[@eightysevenmoore]

Bravo

[@sushantdhamnekar820]

Wonderful Video! Thank you!

[@gervermeulen3051]

Thnx for the clear video! Question: do you know what the requirements regarding the amount of Watts and the tolerance percentage are for the resistors within the plugs? Rgds. Ger

[@CharlesGauthier]

dude, keep working on this. I really wanted to see this but you kept repeating yourself. I think it was just a little bit too off the cuff. Great info, but I could not get through. I will come back and take it in chunks. Keep working at it, your info is great.

[@vineshchandra4798]

Awesome Job Jacob!Thx

[@ahmedalbayati2337]

this is great content.

[@ThomasTheTeslaTuner]

If you have 3-phase at home (even with 16A protection or so) it is possible to use Accelev 2-phase charger with speed up to 5kW (it divides load onto two phases equally).

[@fabriziocattaneo3603]

Great video.. thanks ;)

[@nlo114]

This is interesting, but... I'd like you to write a script, stick to it and speak slowly and clearly. I want to know more, but you keep dashing off at a tangent and I lose track in the gabbling. Keep up the good work but think it through first! :-)

[@Garageaholic]

And he could have edited about 30-40 minutes out of this to consolidate.

[@herantd]

Cool project! But i don’t think that the amount of effort plus the cost(and safety) will justify diy over commercial ones. Been doing some research and found out that Easee smart charger comes with the price tag just around 730 euros.

[@arpitpatel9631]

Hi….I want to make charger with OPCC protocols can you help?

[@lilibethdatu608]

Is it possible to use this as a DC charger?

[@sjitcordite]

kudos

[@wyrenutz]

Thanks great information

[@vaibhav9as]

What will be the total cost for making a prototype

[@Nydeligfyr]

Can this be adaptet to european standart? 3phase 230/400volts? :)

[@vpsaline]

can I convert J1772 to regular type-b outlet?

[@at54tl]

Merry Christmas Jacob!!

[@Mobile_Dom]

Jacob Dysktra? any relation to Chloe Dykstra?

[@ingeborgsvensson4896]

Probably to all the Dykstra and Dijkstra's who originate from the province of Friesland in the Netherlands. There are hundreds of thousands, if not millions, with that surname all over the the globe. My mom was one of them.

[@arklanbk]

ok so if u want to make a charging station at home, you are going to need (apart from the j1772 plug) a 9v power supply, get a power point put in right next to where your j1772 plug comes out so u can just plug your 9v power supply in there. then get a 1khz signal generator to run off the 9v and adjust to where u want your max power output to be (see the wiki)

[@joeabad5908]

Good content, I learned a lot. Though, moving the pen all over the screen while talking and not yet explaining anything on the screen makes me dizzy..😂😂😂

[@CorreoNuevo-rj1tn]

I don't understand English very well, it would be good to add subtitles to the videos. Thanks

[@giantmehdi]

Hey Jacob, can you shoot me a note? I need to talk to you about a project.

[@girishchumbalkar1213]

Bro , By any chance can we make any contact ?

[@pomonabill220]

Great info BUT you repeat yourself WAY too much!

[@bvgb921]

A power brick ?, it's called a transformer and has been for over a hundred years

[@olayiwolayusuff149]

Hello

[@rupsghag07]

hi u r ok

[@nomore9004]

hi

[@gentlebear21713]

Piss poor lecture ...you are all over the map....don't you even have an outline for your talk? You say the wrong thing then correct yourself. You give information , then say it doesn't matter. How is anyone supposed to follow you.

[@roberte.3541]

im sorry but your giving me head ache

[@Themachinewon]

Dude, fix the video, get your wires correct if your going to instruct someone on the pin lay out. Stop with all the snap shots of what you stated wrong,,,

[@jacobdykstra8499]

Themachinewon i make mistakes like everyone else. These are minor mistakes. If you don't like them read the specification yourself and figure it out.

[@bigboss3209]

You are great, keep up doing this and come with new thinks that helps people to save money on overpriced stuff. Thank you for everything you do.

[@gmplascencia]

Great info. Thank you!
