EV general discussion

to each their own but if I am planning a long journey we'll beyond the range of my car I always look for DC charging with a good amount of chargers rather than a small handful of super fast ones anyway. admittedly I am biased as my car only chargers at 100kw anyway (and 100kw is about as genuine as the alleged range of it as well)

but even if my car supported the fastest charging available personally I would still look for large numbers of charge points rather than a couple of mega fast ones.
choice is good I guess but the really big numbers sounds almost like willy waving to me .

Yeah it seems to be a psychological case of fastest is always better. But the reality is how many people absolutely need to move on in 15 minutes or less. There is a reason the majority of EVs on the market seem to target the 30 minute 10% - 80% charging curve.

It’s an old hangover from fossil fuel car ownership. This concept that “I won’t let a car dictate how long I have to wait”. Then they go get lunch for 30 - 40 minutes with the family and most EVs would have added ~140+ miles of range in that time. Even the slower charging ones will add ~100 miles.
 
byd are planning a tesla supercharger face-off with similarly subsidised stations for their flock -
but until they have a saloon hatch/estate my piggy-bank is closed, even though they ring me every couple of months.

surprising fair-trading legislation don't have more to say with such cross-subsidy by other users & market share gain strategies...
I mean if BMW had a deal with shell for cut price fuel for owners ?
 
What do you guys think of the Volvo EX30?
It's a nice car to drive and I like the interior. I've been waiting for the battery modules to be replaced since the safety recall announced last December, so limited to charging to 70%.

Have they fixed all the software glitches yet? It looked like a great car when it came out although there’s been so many news ones since that it’ll the competition has got a lot tougher I feel

You must have missed the anti dumping tariffs over the last few years. Check that with your favourite AI tool

Your piggy bank will never open just be honest about it?

You should just ask them to take them off your mailing/contact list, or alternatively tell them to read your input on this thread and they'll realise you don't even have a piggy bank, well not of money, just baseless opinions.

The software when it first came out was terrible. We've had a number of updates over the last two years, and about to get 2.01 at the end of the month, and it has improved a lot. Perhaps not the best but perfectly useable.
I also haven't found the single central screen an issue - I look out of the window more!
 
It’s all about where they can get grid capacity these days. Back when Tesla first started, grid was less of an issue, it was convincing hosts to hand over areas of their carpark for a decade plus.

All UK CPOs already struggle to get grid capacity where drivers want it. BYD will be no different.

These chargers need to the buffered out with batteries because they’ll not get the grid to support them. They will not be cheap unless they choose to run it on a subsidised basis.

Anyone who has charged at Cornwall services will know that once the buffer is gone, they’ll be capped by whatever grid speed they have at that location.
Thanks, so it seems like it's going to be many years until high power chargers become commonplace then :(

Still, they are also promising their new EVs will have 600 miles of range, so even if both promises miss the mark the combination of better charging infrastructure and better ranges should work together to put an EV within my reach :)

Isn't one of the more modern PHEV's a good fit for you then, or do you not do many trips under 60 miles?

There are already lots of high powered chargers around.

The other benefit of BYD flash charging is that they can hold their charge rate on a ‘regular’ 300-400kw charger for a long time adding a huge amount of range in 10-15 mins.

Genuine question, why 600 miles of range? That’s London to Inverness in a single charge or 10 hours driving.

I'm guessing because it was always 500 miles that ice drivers quoted as the "I'll buy one when" target, now that's been done it's moved to 600 miles :D
 
Only 500 miles? Weaksauce...

I've always wanted an EV because I really like the tech, there's just something cool to me about electric vehicles. PHEVs don't really have that and most of them have pretty poor performance.

I'll try and explain, firstly 600 miles of range claimed by a manufacturer is realistically only going to be around 450-500 real world, so it's only really about 7 hours. But secondly, that's not all you can do with that range. As an example I drive to see relatives 300 miles away every 3-4 weeks, that's a 600 mile round trip but completed either side of a weekend so it's not 10 hours straight it's two 4.5 hour trips and I obviously stop to pop to the loo part way.

Now I did lease a Tesla Long Range years ago but had to return it as the claimed range wasn't remotely realistic and it just wasn't viable for doing these kind of journeys. Obviously with the Tesla or with an upcoming BYD the car would leave my house on full power but that's where the differences become really apparent.

In the Tesla I had to stop on the way and wait for what felt like five days for the car to charge enough to complete the journey, then while I was there I had to take time out to drive to a nearby charging point and then sit around waiting for the car to charge up enough that starting the return trip would be viable (without making two stops on the way back). The real kick in the teeth was that having to charge at public charging points three times on the journey actually made the miles per £ figure much worse than doing the journey in the ICE car I was hoping to replace (and that had a V8 engine) which meant that by using the Tesla I was just paying more money to use a car with a worse interior and loads of drawbacks.

Hopefully with the upcoming BYD models I should be able to either drive there without recharging, charge it there while grabbing a burger or something, and drive back without charging. Or charge it on the outbound/return journeys when I stop to pee. The longer range means that less charging should be require and the faster charging means less time should be required, it's like a win win.

It is kind of funny that I have waited for years for manufacturers to either build cars with long range in order to negate the charging speed issues, or build cars with rapid charging in order to negate the range issues, and now BYD claim to have solved both at once. But then that's good as it means even if they are only telling half truths the two should combine into a usable experience for myself and many others in similar situations.

But yeah, I hope that answers the question :)
 
EV manufacturers need to play within the laws of physics, unfortunately. There's no way around it.

KE = 1/2.m.v^2, and also need to account for drag, rolling resistance and drivetrain losses.

At constant motorway speeds, I would assume that ~4 miles/kWh is the hard ceiling.
So a 600 mile range would require a 150kwh battery.
If accounting for mixed-use/EPA/WLTP then probably a 120kWh battery

Pah - America laughs in your face with their 200kwh batteries…

How do you manage an average of 68MPH with a loo break to cover 300 miles? Are you in the UK or USA (elsewhere?)
