Battery based electric vehicles of today and tomorrow.

Meh. Now's a tough time for getting anything. I just waited 14 weeks for a tractor.

 

[Gale Hawkins]

Had you already paid for the tractor and paying insurance on it?

 

[mwemaxxowner]

No but I think you missed my point.

It takes time to get anything right now. It'd be hard to say whether that's just due to the way things are right now or because it's new.

My coworker ordered a Woodland Mills stump grinder and waited about 12 weeks for it.

MY bad I was thinking it was a made in the USA car when making my prior post.

New Mach E teething problems,

Ford apparently using buyers as Beta testers

Can't get in because the phone ap won't open the door
in a multi driver family and Ford only supplies 1 key.

apple car play won't work'

charge door opens on it's own and then the car won't drive.

Ford can't fix and attempting to reprogram it, "bricks the car where it sits" until a factory tech can arrive and do more invasive programming.

i remember about 20 years ago one of the carmakers was in a deal with microsoft to supply the OS or something.

what a joke....can't get into car? contact your network administrator

i also remember dreading the day when the bit wienies takeover.

Automotive used to be relatively long-cycle, in terms of validating systems.

Test Engineering takes Time, and Money.

My Mom's generation was fond of saying "Your known by the company you keep". Also from that era "Lay down with dogs, Get up with fleas".

Tech figured out a long time ago that First Mover advantage (Musk the best known example today) trumps most everything, and, why pay/wait for Test Engineering to validate, when customers will do it for free..... Automotive has picked up more than a few bad habits from the Dog Flea Tech Hounds.....

I keep threatening to buy a Model A..... I better hurry up, as even w/o Covid, they are getting $$$. One thing I know I'd like there..... an A is probably easier to get parts for, than some 5-15 y/o modern cars.

I've forgotten the exact # from maybe 10 years ago. I was at an Embedded Hardware seminar, and the presenter referenced the Tens of Thousands of software threads running on a then-modern Audi. What he was talking about was just the Infotainment system.

Consumers literally have no clue about the scale of this complexity... and to be slightly objective about it, I can see why Development Engineering just throws it over the wall to Production today.... they run out of Resources/Schedule/Engineers PDQ.....

While flakey tech irritates me in general, I have a BIG problem with this ^ reality, when it comes to any life-safety systems.

BIL bought a 2 or 3 year old Honda from a Honda Dealer not long ago.

Called the dealer to ask if he should call the original owner to see if they had the instructions for clearing their personal data out of the in-dash OE GPS. Home was still set for the original owner.

The dealer sheepishly gave him the instructions to clear the memory of the GPS. BIL is a bright guy, worked in IT all his career. After following the instructions to the letter, the GPS bricked. Non-recoverable.

Dealer installed a brand-new factory unit, @ their cost.

What Could Go Wrong....... Go Wrong...... in these Magic Green Daze of today........ ?????

Yep. the non opening door using a phone ap is entirely unacceptable.
Ford supplying only 1 Key fob with a brand new vehicle is unacceptable.

Many people thought Fords door handle removal was a great idea and trusting a phone ap was good enough for all situations was also just fine.

Ford could have had a virtually identical looking door and opening handle while still matching the wind tunnel drag coefficient of the current design that unfortunately can keep a person locked out by just copying a 30+ year old design of the mechanical design of the W body GM cars like a 1988 Grand Prix. Or at least supply 2 key fobs...
Count me in with the group that believes any fully electric car that could have a burn possibility, emergency need to enter OR exit the vehicle, and/ or be in an accident should have a mechanical way to open the doors. software be ------.

I would use a solar-powered tractor. It's a perpetual motion machine!

Since the sun has a billion years of fuel in its tank you could call that perpetual motion I think.

That is why software engineering was developed. There are ways to write and verify software that are best practices. This field is evolving. It is almost impossible to exhaustively test a completed application and verify that it will function properly under all conditions. That is why you combine best practices with testing. Hopefully you get close. Then it is off to the consumers for beta testing

funny story. i just did a generator service call for one of my long time customers. he asked me if i could also install a 50 amp 240 outlet for future elect car charger. im not doing that anymore, but i gave him a referral. apparently, his BIL came for a visit from Seattle, and since there was no 240 outlet he plugged his elect car into a standard 120 outlet. left it charging for 2 days. when he left to go back home, he had to make 2 stops for recharging car. could not stay parked long enough to top off battery. took him forever to get back home. now BIL is pissed at this guy for not having a tesla charge station at his home.

go figure

I've heard about making a temporary 240 by connecting two 120 lines from different outlets. I would have to do some research to figure out how to do that though.

But still, most outlets are only 20 amps. They need 50 amps for car charger. 80 amps for the soon to be ford lightning truck.

Independent critical thinking....... Or.......

Just go with what Looks Cool, and whatever Lord Musk proclaims......

I happen to agree with you, but much/most of the market today doesn't bother to question these designs.

I bet the BIL will be a one time EV owner or a frustrated EV owner. The world is not keeping up with his expectations fast enough.

Humans, even educated ones, are often not good a doing the right thing(s). Part of the Problem - It can take consistent effort and discipline........ Eating Healthy and Getting Enough Exercise just for example......

Boeing killed a pile of people not that long ago with a deficient design. That happened, with plenty of engineers on staff, AND while operating in an industry that is allegedly even more regulated than ground-transport. THAT ^ example of Regulatory Capture in action today causes me significant concern for the ground based sector....

Software (like any form of) Engineering CAN produce solid results, but it's definitely not a given.

Getting it Right the First Time - psychology is different, between hardware and software engineers. Twiddling bits.... just Wash/Rinse/Repeat as many times as needed..... No Biggie..... so the pressure/motivation to Do It Right isn't the same, as there are less or no perceived consequences for bad decisions.

In the olden days, Beta customers were a tiny group of select customers, usually chosen for being well-informed intelligent users.

Time2Mkt (TTM) today..... just turn it loose broad-market may be more the Rule than Exception.... Recent postings about the Mach E are illustrative....

The newer EV’s take what they get. They won’t take more than they’re rated for, but if you’re charging a Tesla from a 30 amp dryer circuit it will just take longer.
