Tesla have a CVT gearbox? Like actual gearbox that ice cars have? First, I’ve ever heard of them having a proper gearbox. First production ev I heard of with an actual gearbox is the taycan, that has a two speed, fully auto gearbox. Nit aware of any others with an actual gearbox.

You know how regen works right? And that the brake pedal on modern evs don’t engage regen as fully as they are engaging the brakes as that’s what that pedal is for. Engage the brakes and you aren’t going to get anywhere near the energy back from regen as a ton of energy is being wasted by friction and thus heat of the brake pads.

I’ve owned a lexis 400h, i like the idea of them, but cvts are garbage to drive, even in hybrids. They also completely unsuitable for evs due to their wide torque band, they work best for ice engines have have narrow torque bands as the entire function of a cvt is to adjust to a narrow rev range to optimise that narrow torque band.

Any decent car in the tesla price bracket has configurable regen from all the way off to progressively more regen all thr way up to one pedal driving that will apply the brakes for you to come to a complete stop without touching thr pedal.

Vast majority of these it’s switched between the modes using the paddle shift. If you can understand changing gears on a modern ice auto using the paddles, then it’s not beyond the average driver to quickly get to grips with using it for regen.

I’d you feather the throttle as you start to slow down you can moderate the amount of regen dynamically without having to change modes. However that requires more skill than the average driver seem capable of.

Cheaper evs tend to have off, on, and may be one pedal driving modes, but they have to cut things to be cheaper as with all cars.

I get between a fifth and a quarter back of my energy consumption from using regen. Learning how to use it is essential for good economy, and it makes you safer as you plan ahead more for where you want to slow down. The least safest way to drive is emergency braking 10m before a stop sign as your default driving style

You can offer shares to employees to supplement salary, its very common. It could be used to attract or retain staff by offering less salary but a larger overall package than their rivals and tie in the employees for a period of time till the shares vest.

Only downside with teams is that you can’t accept direct teams calls while in a meeting and they can see you are in a meeting. You always get the odd person who dials before asking via chat if you are available so you don’t get the chance to close your meeting first.

Musk banning Apple devices with how popular iPhones are to use twitter would hurt Musk more than it would hurt either Apple or OpenAI so it just sounds like a win win.

The article is about right to repair, third party parts, and systems designed to block both of them, which I applied to an existing problem that applies to planes for certain and almost certainly other forms of public transport. Even a shit idea can be repurposed to improving the common good.

Its not hypothetical, its a widespread issue for aircraft: https://www.independent.co.uk/news/uk/crime/airline-scandal-fake-parts-scandal-b2459534.html

and did you even read what I wrote?

Dont get me wrong, I want a full right to repair enshrined in law and using a system like this just to prevent it is clearly wrong,

With the fake parts scandal for airplanes I wonder if this should be mandatory for parts that impact public safety for public transport like trains, buses, planes and so on.

Dont get me wrong, I want a full right to repair enshrined in law and using a system like this just to prevent it is clearly wrong, but if it could be adapted to allow for critical parts to be made under license by third parties and helped prevent fake parts then may be a small amount of good can come from this shitty practice.

There is a significant scalp market for the limited release Porsche and other premium cars in the UK. Its not uncommon to double your money on some cars just for sitting in the queue for the car for 12 months or so from using a small deposit of say £5k.

Hard part is getting on the list to buy one, you need to be in good standing with the dealer from purchasing a lot of cars, which most scalpers are. You can then sell the place on the waiting list, or finance the car, run it for a short period if you want, then sell it for a big profit.

Some UK prices for comparison:

At home within the EV charging window with Octopus I pay 9p a kwh, outside that window its just over 29p, so I never charge outside the window. I also run my dishwasher, washing machine and anything else I can during that window, typically excluding my EV charging (we are a 3 EV household as both my kids have EVs), we have about a quarter of our electric usage during the cheap window.

Typical cost outside the home for a charger up to 22kw is about 45p a kwh, rising to 75p a kw for ultra rapid pushing out a couple of hundred kws. Its pretty normal in the UK to pay more for a faster charger.

Some places still have free charging but these are drying up, and typically they are limited to a couple of hours of charging at 3 to 7kw.

Petrol is 155.5p a liter, or about £7.06 a (UK) gallon. A modern ICE than is a similar size to my EV should be getting around 50mpg, so 14.12p per mile. 70mpg is possible out of a modern self charging hybrid, this is about 10p a mile. Plug in hybrids potentially offer the same battery power only for 100% of the journey that a full EV offers in the UK for the majority of journeys, as the UK average distance is about 8.5 miles.

Worth pointing out that petrol on a motorway service station (where you will mostly be charging your EV on a long journey) jumps from 155.5p to 177.86p. This increases the cost per mile for the 50mpg example to 16.14p.

My EV gets 4.5 miles per kwh in the summer so about 2p a mile, when its properly cold in the winter than drops to about 3.5 miles per kwh or 2.57p per mile. Assuming an ultra rapid charger at 75p a kwh, cost rises to 16.67p for summer, and 21.42p for winter. Obviously you only charge what you actually need to complete your journey at that price, not fill it up to 100%.

Assuming an equal cost to own and run (which is not the same as purchase price) EVs are significantly cheaper in the UK if you charge at home. If you cannot charge at home then I would look into a provider like Shell installing an on street charger in a lamppost or not bothering at this point if you are motivated by cost.

It’s highly unlikely that they solve what is essentially a heat distribution problem with new battery materials. If you stick a huge number of cells in a giant cooling system then you can charge even lithium considerably faster than we do now for all of the 100%.

We are limited by the space, how good the battery pre condition charging is,maintenance schedule of the car and charging point.

My car has a separate fluid cooling system for ultra rapid charging that has its own maintenance schedule, if this system was bigger and didn’t have to go a minimum of 12 months between changes then it could be charged for longer at higher speeds.

If my car had a bigger battery with more cells in a suitable arrangement then again I could charge faster for longer as the charge is spread out across the battery. However eventually you’ll hit the point that you are only charging a few of the cells as the rest are full and you have to slow down or the battery will get too hot.

I just don’t see them completely solving the heat problem, just improving the current percentages.

Tesla semi is meant to be able to charge at 1mw, which makes sense considering the size of the battery, bigger battery means more cells and more space for cooling. The truck is also meant to support 1mw with the new v4 chargers. So if you believe Tesla (which is hard because of Musk), it is coming.

Charging that rapidly is only possible for some but not all 100% of the battery as you have to slow down as you approach 100%. 350kw chargers slow down around 80% (I’ve gone as high as 85% before I’ve seen the slow down). This happens at all charging speeds to protect the battery, even 7kw chargers slow down for the last couple of percent.

However charging to 100% of the time on ultra rapid chargers is monumentally dumb as it’s considerably more expensive per kWh than slow chargers, slower for that last 20%, blocks chargers for longer, and isn’t good for the long term health of the battery. It is as quick to charge twice to 80% than it is once to 100% on the same charger for 60 to 70% more range from charging twice. This is true because you avoid slowing down at the end of the charge.

Charge to 80% twice, if you read what I wrote, is almost 500 miles, and takes about as long to charge both of those times in total vs. charging just once to 100% on an ultra rapid charger.

As others have mentioned it’s as well as not instead of.

However it’s boneheaded to charge to 100% the vast majority of the time as it’s often as slow to charge from 20 to 80% as it it from 80 to 100% on an ultra rapid charger as it massively slows down above 80.

I can charge twice from 10 to 80% with my car in about 40 minutes for a range of almost 500 miles vs. One 10 to 100% for a range of almost 320 miles in the same time.

I only fully charge at home and only if it makes sense for the journey I’m doing. It’s not good for the long term health of the battery to repeatedly charge it to 100% all the time. Plus it’s kind of a dick move to block fast and ultra chargers with the slow charge above 80%.

Then there’s the cost, I don’t want to spend 45 to 75p a kWh to charge on a public charger when I pay 9p at home on my ev tariff. If I do need to charge I only charge what I need, which can be as little as 5 minutes for about 60 miles.

Sure, not every car comes with 350kw support (or even 250kw) yet, but more will as people realise that charging speed is at least as important as range if you plan to travel in Europe.

As charging at a gas station is always going to be more expensive than charging at home you don’t want to be charging more than you need. It costs me about £6.50 to fully charge my car at home or as much as £54 at instavolt. No way I’m paying that much more unless I really need it.

If I’m charging only what I need at an ultra rapid charger that’ll take between 5 minutes for 20% or 18 minutes for 70%, which is between 60 and 200 miles of additional range. 5 minutes is hardly enough time to nip to the toilet, 18 minutes is enough time to get some snacks and a coffee as well from the gas station.

Plus it’ll only get faster from here.
