EV general discussion

I have to say I actually think we'll end up with more charge points than cars, especially the lower capability ones at 7kW types.

If you consider that every home with off-street parking and/or a garage can have one easily fitted for a low(ish) cost, and in 2010 from a total of 22.4 million dwellings, 40% of dwellings had use of a garage, 26% had other off street parking available, so around 14.8 million dwellings could easily have one fitted, that takes care of the 'majority'.
Then if you add in all of the works places that will add charging points in, which is where a huge majority of cars will end up every day, you could probably add 50% of that figure again if not more.
The all of the shopping centres, supermarkets and places where people take their cars, leisure centres, gyms, hotels, pubs, and a whole host of leisure based places you quickly reach a massive number of chargers that will be there when people need them, even if it is only 15 minutes, but could easily be 4 hours.

Little and often will be the winner for those without the capability of charging at home, some at work (most tbh), some when doing the weekly shop (if they do it online then no), some when they go to the gym, some when the pop over to their mates on a Friday night, some when they go to the cinema, or if they go out to a pub/restaurant.

Companies will be using the incentive of free/cheap charging for customers to visit, be that a local NCP who strikes a deal with Polar etc. Or Sainsbury's who'll give you free charging for 2 hours if you swipe your Nectar card, and then swipe it again at the end of your shop to show you were actually parked for shopping not just for the free leccy. Or just the standard council car park who maybe did some sort of deal with a local business or sponsor to get you free charging. All of these places will add charge point, after charge point and before you know if there will be more than you can count.

Thats my view as well, I honest see it as the equivalent to plug sockets in a house, they will literally be everywhere
 
But that doesn't change anything lol. It will still go completely flat if you just left it. There is no way to prevent it without putting more energy in to it...

I have a 1.2kW lithium battery for my camper. For storing the instructions it says to leave it at least half full and it will last for at least a year before it gets low enough that I need to recharge.

Phantom drain can be an issue yes (specifically Tesla), but otherwise it’s just the same risk as with an ICE. The (usually) lead acid “starter” battery may go flat due to the alarm etc, but that’s it.

... good reading, whilst sitting at the supercharger.

The starting point for chargers should be one per car. It wouldn’t be exactly that but most people with somewhere off road they can store their vehicle will have a charger for every car they have. Then you’ll be wanting a load of additional chargers elsewhere (supermarkets etc). Not an u realistic proposition if they include a lot of existing “charging” infrastructure like normal external plugs in homes.

Also that TaaS is way to optimistic. Yes it’ll be a disruption, but they’re making the standard mistake of comparing future cars with today to argue that change.

It’s not a discussion of whether you buy a non autonomous ICE car vs use an autonomous BEV taxi. It’s a question of whether you buy an autonomous BEV or use an autonomous BEV taxi.

The only way their numbers may work is if electric cars don’t go down in price, or autonomous hardware is too expensive for the average vehicle buyer (or requires too much maintenance).

It’ll also cause issues with road traffic too. The minimum needed if it takes off in a big way will be greater than the number of cars in rush hour, and it would make rush hour even worse as vehicles would be making more trips (going to pick up the second person to take them in, not just parked at work).

mad i mentioned before though, it’s going to be a big industry and manufacturers that can jump in first will definitely benefit, hence why so many are going after autonomous hardware in a big way.
 
Big benefit for large amount of chargers is the two way aspect they offerfor grid balancing with v2G or even v2x. Where renewables have sufficient capacity to store electricity during peak generation. It’s no real suprise Scotland will want to capitalise on their natural resource by thinking of the long term game.
 
Scottish power represenative on Today 7am this morning ... they think we need 25e6 (7K) chargers for the uk, one for every 1.7cars, so should be installing at 4000/day to attain the zero emmisions @2050, and give consumer confidence that an electric car could be refuelled/used as needed. ... so Greta will be disappointed
... it's like smart meter deployment ... or, electric heat pumps replacing gas.

Those numbers are weird.

2050 is 11,027 days away. At 4,000 chargers per day, that's 44.1M chargers, not 25M. Even knocking weekends and bank holidays off, we're still installing 30M chargers rather than 25M.

Still, those numbers aren't necessarily crazy. The vast majority of those installs would likely be home chargers. It took a couple of hours for a sparky to install mine. He could probably do three per day. So we'd need a peak of maybe 2,000 electricians across the country installing home chargers (assuming it takes time to hit scale). Assuming it takes time to hit scale, and only 5M are installed by 2030, 2,000 installers would be able to do the remaining 20M by 2044 (factoring in weekends and statutory holiday).

Today. Just bought an i3. Can’t imagine flooring it everywhere for the lulz will ever get old :D

If a small i3 60Ah is impressive, I can’t even begin to comprehend what a top-spec Tesla must feel like :eek:
 
Finally finished my Ioniq order today. Estimated delivery 12/12. Can't wait! Finally got an EV with decent range.

It doesn't. Still fun four years on.

I just traded in my i3 60 ah for a Tesla SR+ and yeah there a big difference in performance and handling but I still love the design and manoeuvrability of the i3. Plus it has a much more intelligent charging scheduler that adjusts to ambient conditions.

Only downer was the tyre wear from the instant torque so check you rears to get an idea how fast they are wearing. Best accessory I bought was the official BMW environment cover. Covers the windscreen and side windows so helps to keep it cool in simmer and defrosted in winter.

I've used it on my Tesla to keep cabin temps to below 40 DegC but it doesn't quite fit well enough so I'm looking for a similar cover not the usual windscreen inserts.

That's why you'd use a Model X which can tow 2250KG which is far more equivalent of the stuff the horsey crowd usually drive :)

Yeah it works but the tests in the US I've watched show up to a 2/3 loss of range due to how little energy an EV actually manages to work with! Minimum speeds on US highways also didn't help plus they were towing worst case trailers.

Having watched Bjorn on YT they appear to use small trailers a lot more in Scandinavian countries where lots of Tesla are being sold.

is this cured with more elaborate tractions systems ..I thought some ev's now, very accurately, monitor the current/energy going into the motor which is more accurate than the traditional, monitoring differential wheel speed, but I suppose the undriven wheels have to use the traditional system;
(... with a tesla can you break traction easily on bends ..also, not sure how they have dealt with tcr on e-series formula, illegal on F1 )

edit: LOL tcr on forumla e is controversial https://e-racing365.com/formula-e/fia-acts-to-end-traction-control-exploitation/

My impression is that EVs tend to have better control on the traction control via electronics and less mass in moving components to control. The i3 can be quite brutal when accelerating out of a damp corner for example enough to jerk the safety belt. I used see the traction light flicker quite often and not always in conditions I would have expected.

Regen is possibly concentrating wear on one axle adding additional tyre wear though compared to normal braking maybe maybe not you'd have to compare the amount of time and force applied.

Of the ones I’ve seen (TFL etc) they aren’t worst case trailers, they’re normal for their type and you see them regularly around here. I know there was a lot of upset in the Tesla community with TFL, but the trailer they used was a trailer they use regularly in their testing of other cars, and it’s the smallest one they seem to use.

Short range towing is a reasonable strength of EVs (although not as big a benefit as some claim when compared with similar powered ICE vehicles), but due to the limitations of energy they can carry longer range towing is going to be an Achilles heel for a while to come - until bigger batteries are commonly available to offset the range reduction.

Tesla may well end up being one of the worst in range loss in the end due to their philosophy of sacrificing as much as possible for aerodynamics. Stick a roof rack or trailer behind and it destroys the gains they have.

For a European view Bjorn is a better bet. He did some testing a couple of years ago with a dozen trailers - and found the same thing. Even with a small trailer you’re losing a third of your range, with a caravan you’re losing 2/3rds.

https://www.google.ca/amp/s/insidee...ption-when-towing-various-trailers-video/amp/

This is one of the reasons I think there will be a requirement for 600 mile BEVs -especially in colder climates where towing a trailer could leave your 600 mile BEV with just 200 miles of range.

While I don’t disagree towing causes a huge increase in consumption the link you provided doesn’t back up the 2/3 assertion at all, the link says it’s 50%.

You need to remember those numbers will be using the old Model X and not the new ‘raven’ version with more range.

Does anyone know how big a problem is actually is? Are there any stats on the number of people that actually tow regularly?

I don’t mean people who tow a caravan twice a year, I mean those that do it regularly e.g more than once a month tow a significant distance say over 75 miles.
 
So... if the entire UK car fleet moved to EV, there would potentially be a vast reduction in the number of caravans?

I'm surprised Clarkson isn't singing their praises :p
