Why some electric cars have gears despite having access to max torque in all rpm? For e.g new Porsche Taycan Turbo

Edit: Thank you everyone for easy but very well explaination

Why people are excited about new cars before they have undergone a test for practicality, like a sufficient battery thermal management test, software test and charging times?

I watched too many times Tesla Bjørn when he makes his 1000km tests. While the summary on his main channel is almost never negative, his swearing about annoying software, bad thermal management of the battery and noise level are a good indication what to expect. I don't want to make a promotion for the perfect car, but looking at many EV videos when these aspect are never mentioned, I find them boring.

A cheap Chinese car for commuting can be very cheap for commuting, but traveling with such a car can become a very boring experience. A more expensive model for longer ranges may have a problem with justification of a car for commuting.

Anyway to me just praising a design or a price level isn't good enough.

Doesn't a hybrid vehicle have at least the same if not more things to fix compared to an ICE vehicle ?

People note that ICE vehicles are more complex compared to EVs and therefore more costly to maintain.

Wouldn't the hybrid be twice as expensive to maintain as there are basically two systems ?

I don't see how it's the best of both worlds. The gas mileage while better, isn't THAT much better and as I mentioned now you have two systems to maintain which may negate any fuel savings.

Edit: I read a lot of the useful replies but I suppose my point is today one would basically paying for an ice engine vehicle with a battery pack. Granted, the EV part may not have much maintenance, but I'm doing at least the same amount of ICE maintenance regardless whether I use it or not since basic fluids spark plugs mufflers etc,etc have to be done . Even as somebody pointed out some system need both things to work.

The gas savings is somewhat negated by the extra I have to pay for the battery portion at purchase time. In the long run I suppose it would be a savings but then I have to replace the battery ?

Given the choice, I would rather have a straight EV but the quicker depreciation and the uncertainty cost replacement of the battery would be a concern.

Edit 2: I learned a lot. My siblings both have EVS, Volkswagen and Tesla. They seem to like it so I'm looking to either a straight EV something like an ev9, ev5 whenever it comes to Canada. Hybrid might be a consideration.

Why no solar panels?

Why is there no solar panels, neatly done, as the roof of electric vehicles? Most cars sit in direct sunlight.

This is a good example of why we need to decarbonize the grid ASAP. An electric truck charged by a diesel generator isn’t any more efficient than a diesel truck.

This is also why MPGe is misleading. Power plants aren't as efficient as most people think. According to the US Energy Information Administration, Petroleum plants are about 30% efficient, coal about 32%, and natural gas about 44%. So an F150L has an MPGe of 70, but that doesn't mean it's 3 times as clean as a 23 mpg F150. That number is assuming 100% efficiency of converting gas to energy, which is impossible. If it's charged by a Petroleum plant that's 30% efficient the real MPG is down to 21. Factor in transmission losses, distribution losses, and charging losses and you can easily be down to 17.

EVs get cleaner as the grid gets cleaner. Be careful with articles and videos claiming that even an EV charged by coal is cleaner than gas. These are often misleading as they'll take an "average" gas car and compare it to the Model 3, which is one of the most efficient EVs ever created. It's the equivalent of saying hybrids are twice as clean as gas cars because a Prius gets 55 mpg and the average vehicle gets 27. But we know that simply making a gas car a hybrid doesn't double the fuel economy. Once you compare equivalent vehicles like an Ioniq EV vs an Ioniq Hybrid or an EV6 vs a Telluride; the numbers tell a different story. EVs are still better for the climate overall, but we need the grid to get cleaner rapidly to see the full benefits.

What part of Chinese Electric Vehicle am I not understanding

You don't have to be a conspiracy theorist to be worried about Chinese electronic products being a personal (and national) security risk. There are no end of news items about Chinese-made products that include the ability to "phone home" and send information back to Beijing .

https://www.cbsnews.com/news/china-spying-cargo-cranes-report/

If you're in charge in Beijing, what better way to spread your "pnone home" spy tech than to "encourage" BYD to sell inexpensive EV's in the US.

I don't love Tesla, but several million of these in the US? I'll be voting NO with my wallet.

Can a PHEV run with a completely empty gas tank?

Does it vary between makes? Assuming you consistently were to charge the car every single night in your garage and didn’t drive more than 30 miles.

I feel like eventually doing so would cause issues with engine/gas tank atrophy?

Driving to the eclipse (and charging)

The path of totality is not exactly along a great EV charging corridor.

This could get interesting...

Anyone know about Isolated insulation fault detection systems ( or ungrounded ground fault detection systems)

Basically, I am an electrical engineering student who is studying about electrical vehicles. One of the issues of electrical vehicle is that with high voltage battery system, it can short to chassis and with two shorts, it can basically make the chassis live. Usually to prevent this we have circuits to detect the fault. But I can't find material on this anywhere at all?? I want to have a solid foundation and basics on this topic. I can only find research papers but they never go into basics and deep foundations, only results. Can anyone reference me a book or chapters where I can read about this stuff? Thank you!

Anyone waiting on tax refund?

I bought a new EV (Chevy Bolt) last year, spurred in part by the lure of a tax refund to make the cost of it easier to digest. But I’m getting worried now that I’m waiting for my refund. Turbo Tax sent the “your refund was accepted” email on 3/3… since then the IRS tracking site just says “delayed. Everthing else in my taxes is simple and unchanged, so I’m thinking there’s a hiccup with the EV incentive. Anyone else file? Did you get it??

Someone should tell him how lithium batteries work

I used to really respect this guy, and he's very cool with tricks of how to work on ice cars, but man has he gone down a toxic rabbithole. This whole video is more or less a rant about how those idiots in Chicago who don't know how to precondition batteries got stuck in the cold. And then he rants about range...getting real tired of people influencing before they do their research. Opinions?

question re: company reimbursement for EV?

I drive several hundred miles a week for work and my company reimburses for gas. Since switching to an Ioniq 5 in July, they have refused to reimburse for EV charging since they say they "only reimburse for fuel". DOE classifies electricity as an "alternative fuel" and I have all receipts showing kwh/rate/total charge, but they aren't budging - they claim I'm on the only EV user in the company (~20k employees) and have no plans to revise policy. I unfortunately can't deduct these charges on my taxes as a business expense because I am a W2 employee, not an independent contractor. 

Has anyone else experienced this, or have any advice/knowledge of legal precedent here?

Love the Ioniq regardless!!

Bidirectional charging ev9

So the ev9 is to support bidirectional charging and I read Kia says it won't impact the warranty. As yet hardware and software aren't available (I think). My question is is there something Kia needs to add to the car's electronics or should this work with any E-GMP vehicle (once the software is worked out)? I'm currently partial to the ioniq 5.

Their plan is to use the wallbox quasar 2 which connects directly to DC.

I'm patient, so I'm waiting for v2x capability and an easing of dealer markups. Hope to find luck in late 2025, early 2026.

Will non-Tesla manufacturers retain j1772 in North America for AC charging when they move to NACS for DC charging

Major non-Tesla manufacturers have announced that they'll adopt NACS for DC charging. But has any publicly clarified the following questions

  1. Will they retain J1772 for AC charging?
  2. Will they allow AC charging using the NACS port?
  3. Will they retain CCS for DC charging?

I'm not interested in personal opinions or tradeoff analysis. My question is about whether any manufacturer has answered what they'll do with their cars going forward.

What Electric Vehicle are you excited about being released?

There was a lot of talk about the Cyber Truck. It was polarizing and as such got a lot of discussion around it. Personally I think it was a massive flop but that is just my opinion.

Then there was the Apple Car. I think this had a ton of media and discussion because people associate Apple products with the future . People had a lot of curiosity about exactly what was going to be released. This project got cancelled.

There is also the Tesla Model 2. A lot of people are excited about this because of the potential accessible price (Rumored 25k). Additionally there was talk that it would be linked to the future Robotaxi initiative.

There are lists like:

https://www.caranddriver.com/news/g29994375/future-electric-cars-trucks/

So when it comes to Electric Vehicles being released in the future what are you excited for and why?

Holy crap I hate loud ICE vehicles more than ever

Ever since getting an EV (IONIQ 5) I am more and more noticing loud engines and they are driving me insane. Especially when it’s people who make them louder on purpose by deleting the muffler. I’ve found myself fuming when I’m trying to have a conversation with someone and a loud motorcycle drives by and drowns out the conversation. It is so rude and frustrating.

Sorry, just had to vent because I’m sitting here in a parking lot in my silent EV while loud engines roar past on the adjacent roadway, making it hard to hear my audiobook sometimes.

Ugh
