That's exactly it. Residential service is naturally the most expensive to operate. National regulations impose price caps on residential. But Texas is the only state that isn't subject to those rules because they're not synchronously connected to another grid. Which on top of that makes them less reliable, and thus more expensive.
I didn't really understand IEEE until I realized that they're more of an academic society than a professional society, despite what their marketing suggests. The academia mill is a weird way to fund training engineers for industry, and IEEE is just a forum for it.
> Knausenberger said the ACC team would “streamline [existing programs] into one endpoint solution that meets our security, operations, and UX needs.”
Sounds like they're going to get the F-35 of antivirus software. Having multiple programs might not be the problem, but consolidating to just one is an easy sell for a lucrative non-solution.
Security should be practiced in depth. Having only one program that hackers / crackers can write uber-specialized scripts to target seems like an awful idea.
I mean, what if they just bought their people budget laptops with 8-12GB RAM and an SSD, lol. Will be much cheaper over a course of 3-5 years.
Or have good network ops and not allow viruses inside in the first place. A lot of corps have super paranoid (and actually good) teams doing that.
From a user perspective, it protects you from the battery (by protecting the battery), increases the performance and longevity, and informs you about the state of charge. It connects to the battery at the cell terminals and to temperature sensors. A charger is a separate thing from a BMS.
I have no idea about commercial e-bike BMS specifically. But in general, some BMS can, while others won't but maybe should because replacing cells can reduce the safety of the product. It depends on a combination of the cells, BMS, charger, and load. You shouldn't mix old and new cells in the same pack.
Of course, but as an educated consumer who likes to repair their own things I would get all matched high quality cells and replace all at once. If their battery packs don't detect or prevent this somehow then it wouldn't really matter to me.
There's an awful lot of DRM talk in this thread so that was my concern. The cells theoretically are the only parts that need to be replaced sans physical damage
I don't know about DRM. Be careful when joining batteries in parallel. You might not get full performance without the factory procedure for mating the battery and BMS together. Datasheets aren't enough to fully match cells, so the reliability and safety might be less.
When I worked in aerospace, there was a big, one-of-a-kind piece of metal where the fabricators had drilled a bunch of rivet holes in the wrong places. The structural engineers had to figure out if they could still use it. There's bugs in everything.
I have, using Handwriting Repair by Briem. It was less work than I expected, and my handwriting looks pretty cool now. Even if you don't adopt the italic style advocated by the book, the other advice is still generally useful. I printed out the tracing page and did that a few times a day for a few days to get familiar with it. After that, it took a while, but it eventually became natural to write that way. The italic style helps with writing fast.
There's nothing deficient about transmission lines or lumped element models for answering the riddle. Distributed element models of transmission lines [1] clearly show a straight line path directly from the battery to the bulb without going through the whole wire.
Electroboom's criticism is that even if you're not misdirected by the setup, there's still a missing assumption required to arrive at the same answer as Veritasium.
