I built 3 electric cars from 2018 to 2023 and drove them 20k miles. My own firmware and controllers, with an https://openinverter.org https://openinverter.org motor controller
Now I release my knowledge in bite-sized chunks on my new YouTube channel to help others:
What's a battery management system?
https://www.youtube.com/watch?v=_QsMoCrSTYc https://www.youtube.com/watch?v=_QsMoCrSTYc
What is the C-Rate?
https://www.youtube.com/watch?v=dDu1fRtKfsA https://www.youtube.com/watch?v=dDu1fRtKfsA
What is battery balancing?
https://www.youtube.com/watch?v=RGYLPOlT45A https://www.youtube.com/watch?v=RGYLPOlT45A
etc. etc.
I focus really hard on answering exactly one question in a concise and engaging way and trying to keep every video under 5 minutes. Oh, and to make the videos solution independent, so not specific to a product, but convey the underlying knowledge so it has a longer shelf-life.
Full list is here: https://foxev.io/batteries/ https://foxev.io/batteries/
I am planning to turn this into a knowledge base with playlists for "learning paths" like "everything to watch about batteries" or "here is what you need to watch to make a motor spin on a bench". I will add interactive functionality like quizzes and widgets to make the knowledge even more sticky.
- churchill 2y agoSelf-built EV? No one can tell me otherwise: you're the chosen one. Lisan-al-Ghaib :)
- janosch_123 2y agoThank you very much, there is a community of a few hundred of us that have succeeded and not died in the process. Check this forum section here: https://openinverter.org/forum/viewforum.php?f=11 https://openinverter.org/forum/viewforum.php?f=11
- cellularmitosis 2y agoWhy would you self-build when you could just lease an Al-Ghaib?
- churchill 2y agoThe door is over there :)
- hyperbrainer 2y agoYou are the closest I have found to this, even though it is a digression: Do you know of any communities with self-built airplanes? (especially novel-esque designs for propulsion or wings?) I realise these have far more regulations, but experimental GA is something that really excites me.
- janosch_123 2y agoI do not. I know people use https://openinverter.org https://openinverter.org for boats Just yesterday I stumbled upon https://vesc-project.com/forum https://vesc-project.com/forum where they are doing something similar with a focus on ebikes and drones. You are talking full-sized aeroplanes right? I think some of the sail-gliders can be homebuilt, there must be communities for those guys.
- btbuildem 2y agoAlso e-skates and e-mountainboards!
- bronco21016 2y agoAre you familiar with the Experimental Aircraft Association? EAA.org They have had a handful of articles of people working on electric propulsion in their magazine. I would imagine you could reach out to some of those featured. I once contacted a person who was building a DIY HUD and he was very friendly and eager to talk about the project. Overall a very good community!
- ryandrake 2y agoYep, EAA, and chances are, your local regional airport may already have a local EAA chapter you can visit and/or join. If you're into kit builds, there are dedicated web forums and groups specific to many different manufacturer's kits.
- hyperbrainer 2y agoLooks really cool. Thanks
- segmondy 2y agoVery nice. Any video of the cars? I
- janosch_123 2y agohere is a review: https://www.youtube.com/watch?v=W7wRu1xcyQY https://www.youtube.com/watch?v=W7wRu1xcyQY Those guys channel is worth checking out by itself, they are making Ferrari Testarossa's electric and reviewed our taxi on the side.
- wslh 2y agoGreat, do you have a video and/or images of your cars?
- janosch_123 2y agoSure, Tom Scott drives it in this (he doesn't talk about it being electric): https://www.youtube.com/watch?v=ZmWREtcDVBE https://www.youtube.com/watch?v=ZmWREtcDVBE Here is a review: https://www.youtube.com/watch?v=p2xWbfSz8Ug https://www.youtube.com/watch?v=p2xWbfSz8Ug Here is all the media: https://openinverter.org/forum/viewtopic.php?p=49051 https://openinverter.org/forum/viewtopic.php?p=49051 My video tutorials are linked above.
- hinkley 2y agoI still have my fingers crossed that one day someone will build an electric drivetrain for a very common engine design (akin to how people put bigger engines from bolt compatible vehicles into smaller ones so they go faster), and for iconic vehicles so that we can keep them on the road. There are plenty of collectible cars out there that already lack matching serial numbers. Swapping the engine on those is no great sin against history.

- hinkley 2y agoCool. I knew someone who was putting a Porsche engine into a VW, because it required very few modifications to get it to work. I suspect it's not an accident how many of the kits here are for Porsche or VW?
- jedberg 2y agoDo you do contract work? My dream is to use a classic car kit and turn it into an electric car. Basically the kit in this article. :) https://robbreport.com/motors/cars/first-drive-gto-engineering-replica-of-ferrari-250-gt-swb-california-spyder-1234638004/ https://robbreport.com/motors/cars/first-drive-gto-engineeri...
