Comment on White House threatens to veto anti-EV bill just passed by US House
ColeSloth@discuss.tchncs.de 9 months agoThere you go. You keep talking about things being cheaper “in the future”. Well you don’t live in the future, buddy. EVs have been here for over a decade and they’ve only gotten more expensive to replace batteries in. Not less, and unlike many other bits of tech, this has a finite and predictable lifespan that is too short and too expensive for something that currently does too little to help the environment. The government forcing their sale right now is a dumb move.

Source your falsehoods, half wit.
Everything but the battery is lower cost than it used to be. Lightweight cast or semi-monocoque construction, better purity silicon for lower resistance igbts & MOSFETs, not to mention very high speed switching configurations, a big deal that your low-quality ass isn’t even aware of.
The motors have about 6 -15 parts nominally, at the upper end solely if they’re liquid cooled.
I’m an engineer, and I’m calling you a liar.

I’m thahalf wit, and you think some voltage regulators and better silicone make batteries never degrade, while every source available acknowledges a 1200 to 2000 cycle lifespan of ev batteries. You’re a riot.

Particularly, the one who doesn’t proofread.
I notice that you’ve retreated on your other points of expense in an EV, back to the only place you feel safe: the batteries. Looks like I’m winning so far.
Let’s look at your remaining point: batteries.
Ask yourself some questions: what’s the definition of a charge cycle? Does a partial discharge count as a cycle? Your statements suggest poor reading & critical thinking skills, not realizing that in the lab, battery life is tested by fully cycling the battery. Congratulations, you’ve misinterpreted scientific data the way big oil wanted you to.
Like your mind currently, a battery will eventually become feeble. Enough cumulative charge cycles (affected by temperature, being charged at level 2 or 3, etc), the battery will wear out. Here’s the cool part: almost all of the lithium is extracted and purified for recycling into the next battery pack. Redwood materials was started by one of Tesla’s actual OG co-founders, and they’re not alone, there’s ascend materials etc.
So your battery lasts you 10 yrs (with current in-field tech), and even then, still has about 70% of original capacity. Li-ion cells are currently about 85% cheaper than they were in 2010, and there’s a lot going on behind the scenes I’m not free to share showing it’ll continue on a more modest trend .
As the costs continue to decrease due to network effects such as recycling, your poorly sourced fears of replacement demonstrate how dangerous poor science writing can be for the general public. Frankly I would’ve kept scrolling, not responding to your original inane comment but for that people actually seemed to be falling for your pompous charm and snakeoil, vs reality.
