The EV fact thread

[markjay]

This is the best range figure I have seen yet on my IONIQ 5 - it was in the summer, and after driving mostly around town:

But, again, this is not a controlled test and I don't know how accurate these dash figures are.

My point is that depending on the circumstances, real-life performance can be much worse or much better than the WLTP figure (which for my car is 298 miles).

I’d possible stop for a pee but wouldn’t need an extended stop to charge if range allowed. Two of us driving if needed.

We drive from the Eurotunnel terminal at Calais to the in-laws in the south of Germany. This is just over 440 miles, and we normally do it without stopping (both our ICE vehicles will comfortably manage this after topping up at the last motorway services before Dover). We also have two drivers on board and could swap if necessary, but neither Mrs BTB or I have needed to do this so far. When the kids were younger we drove overnight, but that is much harder work and we stick to (mostly) daylight hours now.

Other people may want/need to stop every couple of hours on a long run, which is fine. We are all different.

FWIW I cannot see advantages of ICEs other than low purchase cost for older ones. Range is a non-issue once you can get more than 180 or so miles between charges. It's very easy to adapt to that.

This is my predicament right now. I would buy a used EV in a heartbeat but the significantly higher used car price is a deal breaker.

That's pretty good - no doubt that EVs are efficient at lower speeds. I assume that predicted range would drop steadily if you were then sitting on a motorway at 70-75. Of course ICE remaining range changes based on current driving style too, just the other way round and not usually by so much.

A Tesla owning friend told me the most economical EV driving style compared to ICE is basically the same principles but in reverse.

The problem is my rear window is not the biggest and driving via the reversing camera is very difficult over long distances

Do tell: how long do you think you would you “need” to stop to top up your EQE to complete the trip?

No googling…

Depends on the charger

Depends on the charger

For sure. And on the typical motorway charger?

I think we’re looking for an extra 150 miles. Is that right? You’re starting from home with 250 “in the tank.” Isn’t that right?

Depending on the temperature I should manage 300 on a full charge without having to panic.

20-25 mins would do it with a decent charger available 40-50kw I think

It also depends on whether or not a charger is free when you need it, or if there isn't one free how many people are in the queue, or will there be any serviceable chargers available where you've stopped. Finally, do you need to download yet another app. before you can charge (Tesla vehicles excluded). IMHO the U.K. infrastructure for long distance EV motoring is abysmal at best.

At the moment I’ve only downloaded one app for charging stations, seem to be plenty in most areas, the app tells you how many are there and available at that time along with size/type and cost. Head to any that say they have at least 2 available within short distance and it’d be unlucky to find both being used and having to queue.

From a quick Google the 'real-world' range at 70 mph seems to run from from 235 miles at -10C to 310 miles at 23C (with a/c off):

Mercedes-Benz EQE 300

All details and specs of the Mercedes-Benz EQE 300 (2023-2024). Compare price, lease, real-world range and consumption of every electric vehicle.

ev-database.org

That's quite decent, but it has a fairly hefty battery of course (98 kWh).

Maximum fast charge is 170 kW, giving 10-80% capacity in 35 mins. Range added approx. 225 miles (less at motorway speeds).

Looking forward to city - mild weather… 460 miles would be lovely although I’m dubious

Lots of numbers there, but all irrelevant to the exam question.

His answer’s correct, of course.

just don’t buy a Tesla 3 which has appalling rear vision, through the window, via the screens and over the shoulder….

If the car can give 300 motorway miles on a full charge (at a given ambient temperature) then a 50% charge would be needed to get another 150 miles. That's almost 50 kWh in this case, so roughly an hour on a 50 kW charger (if that's a typical motorway one).

Motorway charges go up to 350kW, but at current the limiting factor is the car's ability to take fast charging. The IONIQ 5 can charge at up to a maximum of 220kW, and that's considered fast - most other EVs can not charge at more than around 150kW. So it's not only a charger issue, i.e. the car's tech needs to be further developed to reach top charging speeds.

If only it were that simple. Either you have been very very lucky or you are new to charging on non Tesla pubic charging points.
Obviously the charger needs to be working and available to use; the apps will not necessarily be accurate on that point. There are a surprisingly high % of chargers either oos or vandalised at any one point in time. Assuming that the charger is actually working then it needs to start the charge on your car - for reasons unknown this is not guaranteed - it just refuses to initiate - at that point you have to decide to either move to the next charger or get on the phone to see if it can be connected.
It seems to be getting better and is now just bad rather than very bad.
Too many problems with broken chargers (sometimes broken for months, not days), chargers that won't initiate the charge, cables getting locked into the car and won't release, no queuing etiquette or system in place at busy chargers and on top of that no cheaper than an ICE car at public chargers. I take my hat off to anyone who runs a non Tesla EV as a main car; they must be more patient than me.
As a second/third whatever car to run around locally and charge at home at night or from solar they are brilliant. A main family car no thanks.

Yes for sure. 170 kW is the maximum for the EQE 300 in question, but the battery can't handle that continuously hence the average rate over a rapid charge drops to 120 kW (from that EV database I linked to, not personal experience ).

Edit - checking the M40 (a motorway I use fairly often) almost all of the chargers on that seem to be 50 kW. Presumably it can be quicker overall to take a longer route, going via faster chargers. I assume some (most?) EVs would handle this in their satnav systems.
