Hello dude it was a really nice video. all thing were nicely explained but i had a little issue in understanding the part how actually the logic of when vehicle is ready to charge and pilot pin is having a input of 6volts how the transfer of energy from charger to onboard module of car takes place.
hey, this is amazing. I thoroughly enjoyed. Can u share the eagle file?Also, I would love if u can add those pushbutton and led display to this small version. I loved the idea that one can control the current supplied and display the power consumed and connect online. I am looking forward to your video on that
Sorry, I do not have the eagle files anymore I made these boards years ago and have not done much board eagle design since. I recommend checking out Jeremy Blum's videos on Eagle they are what helped me design my whole board. It wasn't too hard to design and took maybe a couple hours.
@Jacob Dykstra I am currently building your project on a piece of perfboard but I'm a little confused. You have pin 6 of LM393 set to 9.3V which makes perfect sense for the VehicleDetect pin (5) of the Arduino. But at 50:12 you have pin 2 of the LM393 set to about 3.3V. Shouldn't that have to be more like 6.3V so it can set the ChargeRequest pin (4) of the Arduino low?
Yes 6.3 should be used to detect the vehicle requesting a charge. 3.3V is reserved for another function, I believe it is when ventilation is required by the vehicle.
hey man, can you make a video explaining why the relay coil can interact to physically change the current into the car? I still dont know what chip doesthe powersupply use to actually talks to the relay
The relay does not talk to the car at all. The microcontroller talks to the charging unit in the car using the PWM signal but the relay has no communication purposes at all. The relay is simply like an automatic power switch controlled by the microcontroller. The Current can be changed not by the relay coil but the power electronics in the car will analyze the PWM duty cycle and determine how much current the car can draw.
Thank you Jacob. You have been a great help for my project with your videos and explanation. It would be nice in the future if you can make a video really detailed about the EV charging unit. Keep it up man
Since you power the LM393 with 12V, the output of the LM393 can reach up to 12V. I don't think the Arduino likes 12V on a input pin. What tension/current leaves pin 1 or pin 7 versus the Arduino ?
LM393 is NOT op-amp but a comparator with either open (pull-up done in microcontroller) or grounded output. So there will be no 12V on its output , but the voltage of the microncontrollers pullup will appear there.
@@sinter76 Right, I found it out too after my message. My charger is ready to use but the delivery of my car is delayed with 8 months. Thanks for your feedback and technical info
Jacob, if possible I would like to have that unit in my garage if possible how much would cost me one unit that adjustable current. I have two I3 please how I can avail one unit like that. Gilbert
Hi, I like your video on evse controller. Can this be modified, instead of AC charging using DC. I want a controller so i can connect an external 5kW battery to my car (BMW i3 with CCS) Not to convert DC to AC using an inverter, then the car converts AC to DC. Can you please help.
I have the same question, Jacob did not answer, so martin did you succeed in charging your car from a battery pack of 5Kw directly without converting to AC, and what is the actual voltage of your battery pack? also do you know how much it weighs, as I would like to carry one in my boot as an emergency pack should my car run out of juice and I can't find a charger anywhere.
I have no pilot pen on my battery for my car is just a negative and Positive how do I get around that pilot pen so I can charge my battery the battery is a 36v 100 Amp 18650 cell because all the charges I see all have a pilot pen. like The concept of your charger I would like to charge at different rates Play 12 and 24 V and 36 and 48 v. I have different sizes of batterys
Can be achieved with an GFCI breaker. It is not necessary for the charger to work but if this were to actually be sold and used by the public it would be a necessary safety feature you are correct.
Good point. But I will probably need that... But I'm sure I can figure it out. Also now that I rewatch your Part 1. Why are you not looking for a Stage D, E, F? I don't get what status D is... But I do have a idea how to look for them... Well not too sure for F but the rest is same as C... Also a way to get around 1 second delay in code... You add IF (PowerRelay == Low) delay(1000). Not sure if that is a right way to write this code but you get the idea... And thanks for this. Now I can make a charger that can regulate charging and will not overload my main 20A fuse on a faze...
Gorazd Novsak states A,B, and C are the states used during normal operation. I have never encountered a vehicle which utilizes state D requiring a vent however, with the way I designed the charger in this video, state D will register as state C to the charger. States E and F are errors and I did not implement them in this unit. If there is an error, generally the charger will attempt to restart stages A - C and restart the charge cycle.
OK just figure it out what was a problem with my not working... Yes it took me 3 months to make it... You mislabeled source and drain... And I just copied it to my plan without thinking... EDIT: Well you 2N7000 is turned wrong way. You did "correctly" marked S and D but it is not drown the right way.
Good simple hardware design! Keep up the good work.
Nice to see you back, keep up the vids :)
please make a video for variable version too, it will be great to learn how it works
Nice Explanation Thanks
Excellent video. Can you please, please, explain how to do diode check.

Hi Jacob, is there any way to adapt the controller to manage OCPP and connect it to a server? Great project
Hi ,
Is the 12v supply into the board is used to provide 12 v to all points in your design .Is this ok ?
After having checked the data sheet of the LM393, this one has an open collector output. So it is OK.
Great explanation but i am not getting how to connect my relay to the entire structure.Can you explain that to me? It would be a great help.

Hi we are facing the same problem building the charger can you help us how you solve that problem. we are facing the problem reading output from LM393

Is there a reason why you don't generate proper Pilot? (-12 to +12V)?
diode check not needed
@@Matt-og5kd Diode check is there due to safety reason thought, right?
