Putting the EV in Seven – Two Year Mega Update Video

Well… I finally got to the point where I realized I wasn’t going to be able to upload all the videos I’d wanted to.

For the whole of my Putting the EV in Seven project, I’ve been taking video and pictures in order to put together a series of progress videos for the project. But now being over 2 years behind on this, I decided to cut my losses and just put out one, too long, update video.

And that’s what this video is. It does go through how the project got to where it is now, but it doesn’t cover all the minutia (thankfully, I hear you say).

I cover this a bit in the video, but I also decided to try and keep the production effort down to a minimum from this point on. I’d been spending way too much time on fancy blender animations (like the Permanent Magnet Motor and Engine Cooling animations). So this video is just me talking to the camera about what’s been going on.

Other Comments from the Video

Most of the important stuff is in the video. I talk about the overall journey but there’s probably a bit missing about timelines that might be useful to cover:

So what’s not in the video?

I had a whole video series worked out for the following that didn’t get made…

• Rear motor planning
• Dual rear motor planetary gearboxes
• Rear suspension dynamics mini-project
• Lots of thoughts on space planning different options

Now up to date

So that’s the project pretty much up to date. That releases me to do two things.

Firstly, I’m going to be able to get more videos out. I was reluctant to put short updates out, because there was a whole chunk of unexplained issues that weren’t published and wouldn’t therefore just confused everyone.

Secondly, I’ve been holding off putting out more of these ramblings on this site… for the same reasons. And I also didn’t want to publish here and not have some YouTube content to go along with it. So… I should now be able to ramble on here a bit more now… lucky you!
