Right... when I searched Series Hybrid / EV - it all comes up with the Ramcharger, i3 etc.

AI Definition: "A series hybrid is a type of hybrid vehicle where the gasoline engine never directly powers the wheels; instead, it runs a generator to create electricity, which either charges the battery or directly powers the electric motor that drives the wheels, making it function much like an electric vehicle with a built-in range extender. The electric motor is the sole power source for propulsion, offering smooth, quiet operation, especially in city traffic, while the engine acts as an onboard power plant for longer distances. "

So... really the different between like, the i3 is... you cant plug it up? you can only just feed it gas to the generator and have a good day? Or that the range extender cannot directly power the electric motor, only charge the battery, so that is a key difference?

But the issue was the lack, or issue, of EV engine breaking? 99.9% of the time, you do not just happen upon a steep, long road down with 100% battery... you usually have to go up to go down, or go somewhere to get there from somewhere not exactly "close by"

If the series hybrid you are taking issue with is that, somewhere your going to go down a hill, and the regenerative breaking will generate, effectively more than 50% of the /real/ battery capacity - and where the "physical" breaks are wholly insufficient to do the job - and that the tech that AI mentioned "break choppers" does not exist or is not implemented directly into its created use case in this truck?

Even "where does the power go?" for the generator- AI "When nothing is plugged into a home gas generator, it doesn't produce usable electrical power because there's no current flow; the engine just overcomes internal friction and spins, consuming minimal fuel, with the energy mostly dissipating as heat and motion, like an idling car engine. The generator maintains voltage, but without a load (an appliance), no electrical energy is transferred, preventing that "wasted" power from going anywhere but being lost to heat and friction within the machine"

So... capacitors and essentially heat sinks to dissipate unused - or energy unable to be stored - into the air, as heat.

You would want a "bigger" battery than "just" what is needed to min/max locomotive the electric engine because the up/down of use, the generated power of the generator etc. so... there will be a solution to engine breaking other than explosions.

If this is a big truck or a semi- the size of an already "smaller than needed for complete EV" would not be /that much/ of a cost factor overall in consideration of everything else.

You could definitely call those vehicles a series hybrid in the sense that you have an engine in the system and it's only supplying power as a generator. The distinction I would make is in the scale of the components in the system.

Traditional hybrid: ~1-2kW battery (basically zero range as an EV)
PHEV: ~10-20kW battery (10-50 or so miles as EV only)
EV +Range extender: 50+ kWh battery (100+ miles range as EV only)

I was hoping they were designing something as a more traditional hybrid since it would be a unique application as a truck with potentially some advantages in cost.

When they design a vehicle, they have to account for the worst case applications. I was just outlining one.

You're right that it's not likely to be at 100% SoC at a peak, however, you can see how a smaller and smaller battery is going to fill up quicker from regen. It's definitely an energy management problem that would probably only crop up with a smaller battery.

The analogy of a home generator at no load doesn't really line up. Think of it more like this: you have a vehicle being accelerated by gravity. To slow that vehicle you need to dissipate that energy. Brakes are taking it and turning it into heat, engine braking you're compressing air and producing heat, or you can store that energy into a battery. In a scenario where the brakes would overheat and fade and the battery is full, you'd need somewhere else to put that energy. Braking choppers are very commonly used in diesel locomotives for this, but as I mentioned, would be novel in a passenger vehicle. Caps would work, but cost-wise, sizing up the battery probably makes more sense.

Anyway, it's all a thought exercise since they're doing the ev+range extender option. I'm sure they'll be doing more write-downs when the vehicle comes out way overpriced and doesn't sell at any appreciable volume.

This morning, in 34'c heat (94' in freedom eagles or soemthing..) and 65% humidity, I repaired the 'Exhaust actuators' (Speakers) in my newly acquired Audi SQ5 . .
Here in Oz, we got the 3.0 TDI models, not the supercharged petrol ones you got in the states, and well, the diesel sounds pretty crap.

Audi fitted some 'sound actuators' in the actual exhaust system . . . mine were fucked, so I replaced them and fitted a Kufatec Sound Booster Pro.

Sounds freaking awesome now, and is silent again at the touch of a button . . . . so much better than an $8000 replacement exhaust system.

Audi did a weird thing with this car, but it turned out to be pretty cool in the end . . .

I thought Glasspacks on trucks and Fartcans on ricers were retarded, but that's some next level shit.

That's pretty fucking absurd. On the level of Chrysler's FRATZONIC sound system in its EV car.

Those Slate trucks have my attention. I like the idea of having modular components you can add yourself. Could be interesting for hobbiests?

Who knows. Kinda neat imo

On paper great, but by the time they release, between you name it ram prices, tarriff, etc etc it's going to be dead imo

The range kind of kills it for me. 150 miles on the base version is miserable and 240 isn't much better. Cut those numbers nearly in half for any winter driving. I'm curious what customization they'll actually launch with - I'm skeptical the government won't limit a lot of the things they're trying to do (or make it too expensive). For example, are they going to go through a full battery of crash tests with each body kit? Are they going to have to include a prewire for stuff like rear seat belts since that's an upcoming FMVSS addition.

M2 arrived at dealership tonight and I will be picking up tomorrow afternoon. Didn't think I'd get it in 2025 but made it with a few days to spare.

About time. Please let us know the indicators don’t work, as soon as you can.

And today I come to you to refresh my hatred of modern Ford vehicle engineering.

Earlier I think we covered how Mrs. Haus Mrs. Haus decided that instead of a new car we should just "rejuvenate" her existing one since it still has stupid low mileage and she doesn't drive a ton.

The last step of this project was a rear panel that got marred up pretty badly (beyond just filler, sand and paint). It was a back corner piece. (Amazon.com: UnayKolb For 2013 2014 2015 2016 Ford Escape Rear Bumper Right Side Extension CJ5Z17810APTM : Automotive if you're curious) I bought it off Amazon, paid a pretty penny to have a local body shop paint it for me to paint match it properly. Figured I would swap it out.

One thing led to another and today was when I finally decided to get off my ass and do it since it was a beautiful day here in Dallas and I had nothing else useful to be doing.

I shit you not, no fewer than 5 DIFFERENT attachment methods (screws, metal clips, metal insert clips with screws, plastic insert clips with expanders, and plastic one-way insertion pieces) were all involved, PLUS clip in tab alignment to little slots on the other body parts. And since it was 13 years old many of those plastic clips, expanding insert clips, and such had gone brittle. Thank the voices of insanity from the void that because of fixing some other things I had a nice "utility assortment autobody and interior" box of clips and attachments.

What in any sane world should have been an hour project became a 4 hour slog. But damn if she doesn't have her rejuvenated pretty old car now. Going to take it for a spa day tomorrow to get it nicely detailed up and prettied for her. Since her choosing this option cost me all in, I estimate, around $4000 (New Stereo, back up camera, tires, a couple body trim parts) as opposed to the $25-$30k I was earmarking for her a nice certified pre-owned compact SUV.

I don't like doing any body work for that exact reason. At least you didn't have to align that body panel also I hope.
