I love building all types of electronic projects and automating things. Recently I ran across a guy who discussed building a battery backup using recycled scooter batteries that contained 18650 rechargeable batteries. The same ones that you find in Tesla cars and Powerwalls. <\/p>\n\n\n\n<p>I started thinking. I wonder if it would be possible to trickle charge a battery during low-cost energy hours (6PM-3PM) and then dump it back into the grid when the electricity was expensive(3PM-6PM). Or at least offset your peak hour usage with battery power. So I created some formulas and crunched some numbers. Before you read any further I want to say this is a complete hypothetical experiment. I would never connect this to my SRP system and risk them terminating my services.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"736\" height=\"205\" data-src=\"https:\/\/new.jeremywhittaker.com\/wp-content\/uploads\/2020\/12\/image-4.png\" alt=\"\" class=\"wp-image-169 lazyload\" data-srcset=\"https:\/\/new.jeremywhittaker.com\/wp-content\/uploads\/2020\/12\/image-4.png 736w, https:\/\/new.jeremywhittaker.com\/wp-content\/uploads\/2020\/12\/image-4-300x84.png 300w, https:\/\/new.jeremywhittaker.com\/wp-content\/uploads\/2020\/12\/image-4-500x139.png 500w\" data-sizes=\"(max-width: 736px) 100vw, 736px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 736px; --smush-placeholder-aspect-ratio: 736\/205;\" \/><\/figure>\n\n\n\n<p>Here is a list of SRP&#8217;s different electricity rates.
