Here’s the latest reader question, along with my reply!
Brazos asks: What stops or prevents the array of batteries in EVs from getting covered in typical battery corrosion (CuSO4) like our combustion cars? Are there no exposed terminals? Even metal within the vicinity of the terminals on combustion cars gets corroded from free electrons in the air.
My reply: The lithium-ion battery packs used in most EVs are different from the lead acid (and usually liquid electrolyte) 12v batteries used to start IC car engines. According to what I have read, lithium-ion batteries don’t sulfate.
The greater danger with lithium-ion batteries is thermal runaway and fire from physical damage to the case (as in an accident) or from poor design (Tesla). I fully expect there will be lots of EV fires as time passes and EVs age. Wear and tear of the battery pack and the car (an worn suspension will vibrate/shake the battery) will lead to more EV fires as inevitably as mufflers fall off IC cars from rust and age and years of shaking/vibration as they age.
The whole EV thing is as ill-considered as hiring a $3,000 for the weekend Vegas hoa’r and giving her a ring on Monday morning!
EVs are fragile, expensive, short-lived, impractical toys for the virtue signaling affluent. Which would be fine, if the affluent virtue signalers paid for them – and left the rest of us alone!
