Hi, thanks for the video, very interesting. I subscribed about a year ago when I first discovered you and I look forward to each new video. I'm a retired mechanic and I could see myself building a small EV with the Prius mechanicals. Keep up the good work! Ross
Thank you for the video series. It makes clear this is not an easy process to hack all this stuff particularly depending on others hacks. I was a big proponent of using prius parts 10 years ago, but with the leaf's out and now old and cheap, there is no reason to anymore. The leaf drivetrain is very easy to swap into anything, I just bought an insurance total for $400 that is a running 35 miles range car.
@@murraymadness4674 Yes you right old leaf's are very cheap now probably the best option out there. For me the main goal was to learn how these things are working while doing it cheaply. With the Leaf probably better to use Zombie to control Nissan electronics via can commands. But if you want to do it in more interesting way you can put Open inverter board in the leaf inverter.
Thanks Ed, your timing is impeccable as I am about to start tuning my Yaris inverter with an Outlander rear motor. I find you videos complement Damien and Johannes’ and boost my confidence in what can be achieved. C
I love this! I myself fantasize with the idea of converting an 2nd gen Prius into purely EV. Your idea of using most of the gear is brilliant. I look forward to learning about your progress with each video. Good luck on your endeavor!
There is the EV Switch mod that you can read about, however the battery isn't designed to run as an all EV vehicle for more than very short periods of time. I'm no certain about the rest of the parts where maybe additional cooling I'd think at the very least would be required like with another separate radiator and maybe fan. I'm still learning however and may be wrong. There definitely is an EV switch mod that's not that expensive to perform to get the option at least.
@@jafinch78 I think you might be on to something; I vaguely recall reading something similar in these Priuschat website. A battery upgrade wound be a must; as you pointed out, it wouldn't go very far 😅. Thanks for sharing. I'll investigate.
Thanks for sharing this video, the FOC explanation is very good. Can you share the make model of the power supply modules, have you chosen an car to fit the Prius motor into.
Thanks I am glad you found it useful, as for the power supply I would not using exactly that model as they are quite expensive and not really the best for this task. I just used them as I already have them from my previous work. If you can get any power supply from 60 to 100V and reasonable current you should be fine. As for the car I made a video about it. Called What car😁. At the moment I am gravitating towards Audi TT gen1 or 2 simply because I like it and it is quite small and relatively light
hi my name is Ramzi thankyou your videos its very good information . pleas can you tell me if i have inverter and gearbox for toyota hybrid high voltage 200v and low volte 12 i thing you say on your video showing pin 1 to 12vold+ and pin 5 for start pleas can you give more information . thanks
Hi. Do I also adjust my motor and have a lot of voltage to set everything up correctly? I think I set it up well, but when I give the engine gas as if it jams, the field weakens
@@LatutaEV Yes. It's all right, the engine spins well. I did as you did, on the FOC firmware when setting up syncofs also works well, but at low syncofs values. I found a good synchronization, it's 32650, the motor at 100A makes sound, but it doesn't spin like yours. When I try this setting at the beginning, everything spins well, I press the gas pedal and the engine starts spinning, but when I give more gas, the engine slows down and twitches, I think this is due to the fact that the weakening of the engine field decreases. I, like you, use a power supply, a server power supply. I have 53 volts on the battery side, so maybe it's because of low voltage?
Im confused. Was the motor controller designed to be universal? Or was it designed to work with the mg1 and 2? If so then all the settings should be known already
Open Inverter designed to be adaptable and tuneable. For example Damien has board that works with Tesla motor and Leaf motor. In this case I am only controlling MG2. Initially my plan was to have both MG2 and MG1 locked together and control them with the dual board that has two STM32 processors but now I am thinking about removing MG1 and have two MG2 with two inverters, but I am still undecided on this for now.
Really enjoying your work, Really interested when you said you were going to use two separate mg1 . Is it physically possible to separate drives as I'm hoping to to connect to a stern drive in a boat and either mg1 or 2 would keep weight down,
@@seancosy1 as MG1 is quite small and the gear ratio is not favourable I think it may be better to remove it. The complication is that oil pump is connected to the shaft that goes through MG1. If you watch Prof John Kelly videos he shows all components of the Prius gearbox. At least you can always remove MG1 and drive MG2 only. I was thinking about connecting in parallel MG1 and MG2 inverters to get more power as well
Mainly because I stumbled upon a fairly cheap Tesla motor and fancied to have that in the car. But I got a Prius motor working so I may use it in future projects.
I don’t understand why you’re using a Toyota gearbox and inverter to make an EV Would it be easier to convert Toyota Hybrid? Instead using Toyota hybrid parts only
Good question 😊 the explanation is quite simple - it is the cheapest option to learn from. I am planning to experiment with Tesla motor after I have done this one. As for converting Toyota hybrid I don't particularly like Toyota's apart from newer models but I wanted to convert an older car like Celica or Audi TT
I understand zero from what you are doing right now, but you have my outmost respect... Keep up the great work my friend...
Hey Carlos thanks for the comment, how you doing my friend 😊
Very useful, thanks
I am glad you found it useful 🙂

Excellent, glad I could help. Let me know how it goes. Will you be using PSU or batteries?

thank you for your answer . but i can't connect to power
Are you talking about power for the open inverter board?
I currently have 6x12v gel cells that got the motor spinning in open loop. I think I may need to add more cells and/or psu for foc tuning.
I think you could try but it may be better to have more than 100 volts.

I think I have answered this question on another video already please have a look
Hi. Do I also adjust my motor and have a lot of voltage to set everything up correctly? I think I set it up well, but when I give the engine gas as if it jams, the field weakens
Did you try using sine firmware? and was it spinning ok with sine?

@@Max-fc2zq I suspect that you need to go higher in voltage and current. This would be a good stage to move to a battery ☺️
@@LatutaEV Okay 👌. Thank you for your help
Im confused. Was the motor controller designed to be universal? Or was it designed to work with the mg1 and 2? If so then all the settings should be known already
No it's not universal. It been hacked, with the hack it is universal.

Why did you stop your investigation on Toyota Prius components and go on with Tesla?
Mainly because I stumbled upon a fairly cheap Tesla motor and fancied to have that in the car. But I got a Prius motor working so I may use it in future projects.
