Comment on EV Batteries Are Dangerous to Repair. Here’s Why Mechanics Are Doing So Anyway
NAK@lemmy.world 6 months agoI swear, everyone on Lemmy have their heads shoved so far up their asses about how everyone should go full internal combustion and that they’re great and have lower maintenance costs just down vote me to hell when I bring anything like this up. I know the tech and work on vehicles and combustion engines. It’s dumb to buy a $40,000 vehicle with a 300 pound engine, 200 pound transmission, mechanically complex 4 wheel drive system with upwards of 3 independently locking differentials. The resale value when the head gaskets is blown is next to nothing, and the great 5 year 60,000 mile power train warranty doesn’t even cover the average mileage people drive in 8 years. It only requires you mosty pay off the average loan length for a new vehicle. My Tesla costs 13 cents to drive about 4 miles, where the equivalent combustion car, with 400 horsepower and 400 foot pounds of torque, costs upwards of a dollar to drive the same. The high strung powerplants in performance cars require regular, expensive, maintenance, and if you actually push them will blow up in under 10,000 miles. An LS3 crate motor costs more than the car is worth and that doesn’t even include the transmission or any of the other drivetrain components. No one should buy and keep a combustion engine for more than 10 years or you risk “being the bag holder” and stuck with a cancer emitting 4,000 pound paperweight.
I mean, I’m all for EV, but my car is over fifteen years old and still cranks every single time. Gets almost 40 to the gallon. Yeah, the resale is shit, but if I drive it until the wheels fall off, I don’t have to worry about that.
Their argument was valid other than their martyr complex
It really isn’t.
The whole point of the crate motor vs battery pack was it’s ridiculous to compare the cost of a new battery vs a used engine. If you blow an engine in a regular car it’s replaced with s used one, even if it’s covered by warranty. Used battery packs will get cheaper with time, especially 8 years from now when the warranty on a new EV is done.
Good for you that your car hasn’t broken yet. I have a friend who got a bad transmission in her Subaru, it was replaced after something like 500 miles. Are you claiming that every new ICE vehicle that had ever been sold have had 100% working drive trains for the entirety of the restraint period?
Or are you comparing your anecdotal experience with a FUD news story about one person who had a lemon of a vehicle that happened to be electric

First of all, find me a corvette that blew a motor under 100,000 miles without being abused to hell first.
Second your trying to compare a sports car tesla with all its speed unlocks to some sorts of all wheel drive sport car with an automatic tranny? I’m talking more about common cars for getting around in like a Camry compared to a tesla model 3.
Also to that effect, 95% of the time if you change the oil in a camry every 7,000 miles and the transmission pan fluid every 50,000 miles the motor and transmission will last over 300,000 miles. If the engine does blow you can get a new one installed for $5000. If the tranny goes out it will cost you $2,500. When the battery of a model 3 goes out, which is guaranteed regardless of how well its cared for due to its chemistry, a battery swap will cost you $16,000. Double the cost of a motor and tranny.
You spout the same misinformed nonsense as half of everyone here. You don’t know how things work. You don’t know battery chemistry. You don’t know how to make your own repairs. You still try to have an opinion. Save it and stick my name to it. All of you people are going to start figuring this out over the next five years when the junk yards start filling up now that mass produced EV"s have been in production on a large scale as the earlier ones approach 15 to 20 years old.

You can buy a model 3 that goes 0-60 in 3.1 seconds, right now, on their website under 40k after tax rebate. Go look. Under existing inventory. All prices exclude the 7500 credit.
Are you claiming GM never made a lemon? That no cat, ever, in the history of their company, was sold with a bad motor?
And stop it. You’re comparing the cost of a new battery now vs where the cost of a used battery will be in 8 years. Claiming that technology doesn’t get cheaper is absurd. You can buy a used Nissan leaf battery for $370.

Dude. You obviously don’t know how a used or refurbished ev battery entails (it’s a terrible option) and a Honda leaf has an 85 mile range. It’s a small battery (why they’re cheaper. It’s less battery) and you can replace it without ripping the car apart. An 85 mile range is a replacement for almost no one. Model 3 is the most sold ev in the US. Go educate yourself on what it actually takes to replace That battery. FYI- it’s a 1,060 pound battery. You have to pull the back seats, disconnect it, raise the car up on a lift, drain the coolant, disconnect the lines, use a special jack setup to support and lower it (its across the entire bottom of the vehicle between the front and rear wheels) and then raise the new one up in its place. You can “man handle” a little leaf battery. The model 3 will cost you $20,000 between battery and labor.
Also, who cares how fast your car can do 0 to 60? Are you 17 and think it’s cool?

Cole, shut the fuck up. You’re what we call a shade-tree mechanic, and a particularly weak one at that.
What was the lack of understanding you showed last time, something along the lines of “show me a battery you can get more than 1200 cycles from” and when I pointed out that you didn’t understand the definition of a charge cycle, you just… Vanished.
What’s a charge cycle, sloth thoughts? Is it what a battery in the lab, going 0 to 100% to 0 does to determine longevity? Is the more realistic 95-45% a “cycle” or only part of one?
Is losing 75 miles of capacity on a 220mi battery after 12 years on a car unacceptable? Aw poor genius, I guess you don’t remember how shitty gas engines run after about 2-300k miles. Meanwhile your electric car has gone a minimum 300k miles (250mi x 1200 cycles) and are still able to accelerate with full power and efficiency.
As I said before, people like you are why we have professional engineer licenses, lest the pubic believe a charlatan lowlife such as yourself.
