My wife owned a horse for 18 years. I could be retired now if she had a different hobby. If you like to keep your money, DO NOT marry a horse woman (unless she already wealthy). |

I think Toyota had it right 25 years ago with their hybrid technology, and that they still have it right today continuing to lean on both hybrids and now their PHEV's. Lots of manufacturers are going to lose billions of dollars on EV's that they can't sell, but not Toyota.

When they first came out, I started to see the Ford Mach-E just about everywhere. There were TONS of them on the road almost overnight, and people were buying them like crazy. Now I hardly see a single one. The big issue here is lack of infrastructure for anything other than Tesla's. Just for curiosity's sake I checked reviews for some of the other non-Tesla public charging stations in the area, and most of them don't work at all, and are constantly broken and needing to be repaired. So unless you're home charging, you're screwed. I'm sure Ford quality and recalls and software issues didn't help, but people very clearly and quickly unloaded these things over a year or so. Plenty of Tesla's here, though. I have no problems with EV's, but you have to have the infrastructure to support them, and nobody wants a vehicle that's going to blow up in your face, metaphorically or for real.

Perhaps the pending EPA emissions regs proposed by the current administration will drive development of cleaner, more efficient ICE to power a true series hybrid. It won't happen in my driving lifetime, but I'd happily give up my manual transmission fettish for a true (pure) serial hybrid. I love the EV drivetrain from an engeering and energy usage perspective, I just think carrying around a huge, slow charging, heavy battery to power it is stupid. |

Here is an interesting paper from 2 years ago that talks about charging rates, lifecycle, safety etc.. https://seas.harvard.edu/news/2022/0...rs-solid-state Also, equivalent density SS batteries weigh about 1/3 of a Li-Ion. That will make a difference in efficiency and safety. Quote:

I would trust Toyota to "get it right", I just know for a fact that they're not going to be inexpensive. Just a guess, but I think you're far more likely to see this battery technology deployed in some $200k exotic first, like a hypothetical "LFA EV," where every bit of range and performance counts. Then, once they can ramp it and bring costs down, it will finally find its way into lower and middle tier consumer transportation appliance type vehicles.

In 1900, i could buy 6.6 solid horses (or 100! old nags) for the cost of a car; 5.6 once the model t came out. I would much rather have a different horse for each day of the week than be stuck w just a single car. More expensive = bad, full stop.

However, one only needs look at the state of automobiles at the turn of the century to appreciate how far we can bring a technology. Id take a g87 over a model T any day. With AI helping now? Cars might fit in a backpack one day.

Nobody is banning shit. If GM approached the US govt with a clean, easily sourced hybrid that required a fraction of the infrastructure and still got 100s+ mpg/range, there is absolutely no doubt our EV attitude would at least be questioned, but likely changed. There are still smart people in this country.

My point has always been the analogy of 19th century pushback on automobiles (assuming by horse users) is not relevant to the question of ICEV vs. EV in the 21st century. Cars (and tractors) were new technology in the late 19th and early 20th centuries. EV is not really new automotive technology, it's just a different fuel source that requires a minor architecture adaptation to the current automobile. In the 19th and early 20th centuries the internal combustion engine was a new technology to get work done at a higher quantity for a lower cost. EV do not provide any technological jump over the ICE-powered automobile in the same manner the automobile (and tractor) did over the horse. Until 1990 when CARB began forcing the requirement for "zero-emission" vehicles and the made-up associated climate scare meme, the automotive market didn't give a shit about electric cars. The market still wouldn't give a shit about EV if not for legislation first incentivising it and now mandating EV. The majority of posts in this thread is over the forced adoption of EV by government legislation. Last edited by Efthreeoh; 04-18-2024 at 01:33 PM.. |

The charging of almost any battery is a chemical reaction to store the energy. The rate of charge is limited by numerous factors like the chemical reaction speed and control of heat build up. In RC Racing we use far more sophisticated chargers that monitor individual cells and balance the charge. This is not the case in a EV LiPo battery which balances packs not cells. Fact is the faster you charge a LiPo the greater internal resistance in the cells and the lower capacity and shorter battery life. Many companies have been saying they have 5min recharging but I have yet to see commercially available prototypes. A while back I posted an interesting article on a new technology that changed the fluid electrolytes for ICE like recharges. https://www.purdue.edu/newsroom/rele...tomobiles.html If you have 3-phase current 480V voltage. A 250 kW V3 Supercharger charges at 300amps Charges a Tesla Model 3 from 5 to 90 percent in 37 minutes |
