Ok, I need to get this off my chest. It's been bugging me for some time now, and a recent YT video made it worse.
Terminology matters. A lot. In engineering, words have specific meanings and these terms help us communicate ideas and concepts correctly. When people start assigning other meanings to these terms (especially in the same field) things become confusing, and the words lose their precision and surrender some of their function.
Why am I bringing this up? Two words: "Eddy currents".
Eddy currents have a very specific meaning in electrical engineering, that is, Eddy currents are "loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction". The term "Eddy current" has nothing to do with the current that flows from one battery to another when you hook them up in parallel. As far as I know, it was Orion (from the Orion BMS) that started using this term incorrectly in this one document:
Sadly, other people are picking up this term and referring to this document with a "see, they're using it, they're Orion, it must be correct" (paraphrased). It's not correct. Orion is wrong (on more than one thing in that document, but I digress). Stop abusing terms with clear definitions that have nothing to do with the issue at hand or are even close to the meaning as set forth by the definition. Please use the proper terminology so we can all understand each other, and can continue to do so going forth. Use the correct terms, and don't try to assign existing terms and their meanings to something else. It's confusing, it causes communication problems, it serves no purpose.
