I also cover how multiple AC phases (3-phase) is used in practice.<\/p>\n\n\n\n<p>The second video will go into more detail about the different components I\u2019ll be using in my EV conversion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">TLDR;<\/h3>\n\n\n\n<p>Ok, so the \u201cToo Long Don\u2019t Read\u201d of this video is that it, and its follow along sibling, have taken me 8 months to produce. The 9 minutes of this video and the 19 minutes of the second have taken FOREVER to get done, and don\u2019t really reflect the time that\u2019s gone into them. I\u2019ve created countless animations and scripts, and then editing it all together has taken an age too.<\/p>\n\n\n\n<p>Most of the 2D animations (block diagram, battery cell animations, battery animation, AC and DC simple circuits) were done in Apple Motion (the video is done in Final Cut Pro).<\/p>\n\n\n\n<p>The 3D animations are all done in Blender (motor internals, car, car and charger, car being charged, fast charger scene, torch and house being lit etc ).<\/p>\n\n\n\n<p>The biggest of those tasks has been the Motor Internals animation in Blender. I\u2019ll cover that in the post about the second video (here when it\u2019s published).<\/p>\n\n\n\n<p>For this Electric video, the major element was the creation of the oscilloscope Apple Motion generator.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Battery Generator<\/h4>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1152\" data-attachment-id=\"8572\" data-permalink=\"https:\/\/purplemeanie.co.uk\/apple-motion-battery-examples\/\" data-orig-file=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-scaled.jpg\" data-orig-size=\"2560,1440\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"Apple Motion &amp;#8211; Battery Examples\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Apple Motion &amp;#8211; Battery Generator&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-600x338.jpg\" data-large-file=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-2048x1152.jpg\" src=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-2048x1152.jpg\" alt=\"\" class=\"wp-image-8572\" srcset=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-2048x1152.jpg 2048w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-600x338.jpg 600w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-768x432.jpg 768w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2024\/02\/Apple-Motion-Battery-Examples-1536x864.jpg 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/><figcaption class=\"wp-element-caption\">Apple Motion &#8211; Battery Generator<\/figcaption><\/figure>\n\n\n\n<p>Ok, so lets start off with the first generator I created for this Putting the EV In Seven mammoth YouTube project.

I may make a future video that better replicates both aspects, but that would be more to create a WOW! Factor rather than being particularly useful as an explainer.<\/p>\n\n\n\n<p>Again, I\u2019ll cover this in the second post, but I\u2019m really happy with the way the motor internals animations have come out.
