Don't you see the problem here? Your honest or feign sheer ignorance makes impossible to discuss anything with you. Every AC motor becomes a generator when mechanical energy is applied to the rotor. The only thing the system needs is to change the contacts to charge the battery which is the principle of regenerative braking.

Whaaaaaat? Since when an AC motor has brushes? Do you even know what you are talking about?

Whaaaaaat? Are you seriously saying that any EV would have lead batteries? For frigging real?

It's a solid block of lead weighing around 3000LB's minimum PER BATTERY in such a vehicle (Based on today's tech) and not so easily moved - Hit that running 55 and you'll get the point.

Lead again...

EV batteries can be cooled or heated granpa. In fact it is the principle for heating for passengers or maintaining performance level in cold weather.

And now I'm absolutely sure this isn't trolling but sheer ignorance and talking about something you don't know the first thing about.

LoL,

Let's see.....
Motors?
Well there's the armature, brushes, bearings, cabling, and more to inspect while repairing or replacing anything found bad or going that way, inspect the motor lugs to be sure they aren't coming loose and also be sure acid hasn't affected the motor itself (Based on battery proximity to the motor).

And that's not all.....

Battery?
Cables, battery holddown(s), electrylite level, inspect the case for swelling/leaks/damage, be sure all vent caps are present, be sure any acid buildup in the area of the battery is removed and from the battery itself, be sure the battery tray isn't about to be eaten away and let the battery fall through........

And that would mean right into the road itself in this case for all to dodge/crash into.

Do me a favor...The next time you go there, pick up a radiator to a 66 Corvair Corsa (Has the 140 HP engine) for me please.
Mine's leaking.

Again what is specific to Evs?

What will make the EV a disadvantage to ICE.


All Teslas use battery coolant. Didn't you just tell me i knew nothing? lachen.gif

I would assume it is battery coolant and brake fluids like any other EV headscratch.gif

If you like to maintain then Evs aren't for you.

Do me a favor. Tell me where you read that Musk's electric trucks are going to use lead/acid batteries. Or did you not bother to read any of the linked articles?

I'm not going to lie - I find it quite funny that someone actually thinks that SLA batteries and brushed motors are still relevant for traction in anything but kids toys :lachen:

I see your arguments but they dont readily apply to the trucking and automotive/industrial industry

Why would you assume the answer to any of those questions is no?

There would have to be new regulations before these trucks to be practical on the road, same as when air brakes first came out (the old hydraulic brake regulations wouldn't apply there very well), etc.

It not about the regulations. He knows we are talking about engines and motors... Why mention wiper blades and windshield chips to try and prove someone wrong? rolleyes.gif

There is way less mechanical stuff to inspect on an EV.

OK a last stitch effort here.....

I'm not entirely sure what I'm trying to prove "wrong" as opposed to showing the simliarities and differences of tractors. There was mention of no longer needing to maintain battery terminals, the wiring and such, I was simply stating this is not true as there are regulations stating these things need to be attended to on periodical time periods and nothing more than that. Wiper blades happen to be part of PMs, it was a simple statement that PMs still need to be carried out even if the truck is full electric as someone stated that PMs would no longer be necessary.

I think it's a neat concept. But a lot of you people think this is something NEW to the market while it's been around probably longer than most of you been alive.... I certainly wasn't around in the 1920's when electric vehicles where around.......

I really like the idea of having say 750 foot pounds of torque at 0rpm. It's great for making a fast car and short distances.

But since this tech has been around for.... oh gosh... what 10 decades or so.... It's made more progress in the last one or two decades but still not viable enough for trucking companies to consider.

I cannot afford a Tesla. However I could purchase any used tractor or gas car for pretty cheap and make loads of money with it, while the EV vehicles with what some of you may consider "NEW" technology (which it's not at all) just are a little expensive to implement into a trucking company at this time.

You people need to remember that delivery doesn't really make a lot of money. Most private drivers I know are not making some golden profit and saying that net 6 figures every year.

It's not new. It's not affordable (YET) and probably won't be until we can make batteries a little less in weight and affordable.

That's all I'm really trying to get across.

And Fitz, I apologize for the type. I'm not really desperate.... it was just a typo thumb.gif

Well hopefully the Tesla version of the semi has a much better range than the Daimler electric semi in testing now, with a range of 124 miles on a charge.

Now I'm curious how bad a battery fire would be if it is so massive. I don't know that the semi trucks have a huge number of major accidents per year but it seems like since the inception of electric / battery powered vehicles they were really a lost cause if they caught fire. Maybe they will have some fire suppression or other methods in place for future e rigs.

Out of 67 tractors at my facility 3 of them involved in accidents this year, one of those actually parked and docked and someone drove their Jeep right into the front grill. That was 7,000$ in damage lol.

Battery fires happen. Ask Samsung. They'll tell you all about that recall!

Range and cost is a really big deal to a trucking company. Right now we are suffering loss of profit on regulated electronic emission control systems. Sure our new ones are under warranty, but we loose money sending this tractor to the dealer with the down time. Any time the tractor is down for any reason, it's not making money, but the payment still needs to be made. However we get discounts for paying in full....

Thanks but I'm more concerned about you quoting someone else and accusing me of having made the quote and quoting me out of context.
