Charging Etiquette

[Scandinavian]

Ultimately I think two entities are to blame for folks not understanding the process: EA has set up their chargers for failure by only having 2 350kw stations (one of which seems to always be down) and car manufacturers for not making things plainly simple in explaining the maximum rate of charge for their cars. For example, it took me 20 minutes of digging to find the max charge rate of an Ioniq 5, I had to pull it out of a random article after looking for it on Hyundai’s website in vain. Manufacturers seem to only be publishing the time it takes to charge, (ie. “10-80% in 31 minutes) as opposed to explaining; “hey, this car can charge at a max rate of 150kw”.

Good point about the manufacturer only specifying the 20 to 80% time. It is hard to see the max charge rates for many cars.

Just wait until the new Hummer turns up at a charging station. They are super hungry for electricity and can charge at very high rates, but the battery is some 225 kWh.

Correct etiquette if you don't need a full tank on a 350kw charger - Occupy for the time it takes to eat a bacon roll, have a coffee and a wee.

I decided on our trip back from Wales to stop at 2 chargers, one was nominally 150kW and the other 350kW. It is around 225 miles and I charged just as long as it took to have a drink and wee in each case, so pretty well zero extra elapsed time for the journey.
If I tried to do it in one stop it may have overall taken longer Because of the charge rate slowing above 85%

Ioniq 5 - details easy to find (1 click)

220kW and is also 800V architecture, 10 to 80% 18 - 36 minutes.

Data easier to find on the Hyundai website than it is for the Taycan.

Please don't upset Ioniq 5 drivers as they are entitled as Taycan owners!

Indeed, it may have changed now but when I ordered the Taycan the only cars available in the UK which could exploit they high charge rates of the 350kW 800V chargers were the Ioniq 5, then Kia 6 and Taycan.

Not meaning to knock Ioniq 5 car, but just saying in general. But also confusing for a newbie to see a charge time between 18 to 36 minutes between 10-80%.

It is there in the specifications for a EV,but not always easy to find. And as a newcomer to EV it would probably just be confusing, with 400 volt, 800 volt, kWh battery and kW charging rates, AC and DC charging, level 2 charging etc. etc.

And yes, i get it that the charge rate tails off massively above 85%, but sometimes you do need more to avoid an extra stop.

Avoiding an extra stop seems to indicate that there actually is another HPC on the route? If so I would suggest that it would actually be faster to add an extra charging stop and plan lower SoC at each stop. But it all requires quite reliable and suitable chargers along the route.

If you look at some of the you tubers that test cars on long trips, they are typically charging from about 10% and sometimes to only 60 % in order to get the fastest overall passage times.

Yes. But taking risk that the next place will have a queue or broken down evse.

some of the comments here are absurd. if I feel that I need 100% to make it to the next charger I am charging to 100%.
end of story

I wish they would just make all chargers 350kw at a site.

EA in West Fort Lauderdale just changed over to ten 350 kW Chargers. The downside is you’re guaranteed to get panhandled virtually every visit, and I definitely would not venture there at night, no bueno.

What they (at least i believe they are) saying is that if you dont need to charge to 100%, dont do it. If you absolutely need all that range, then you do what you have to. it just takes an extraordinarily long time to get that last 5%-10% charge. 20-30 mins to get to 80-85% and it could take an extra 45-60 mins to get to 100% from there. If you need it, feel free to go for it.

 

[Atipical]

I have no problem with folks making it to 100%, make no mistake. My problem is when a dude in an ID4 goes from 5% - 100% using a 350kw charger. Effectively wasting everyone's time when he would get the exact same experience from a 150kw and not inconvenience anyone that can properly use a 350kw charger.

 

[TYKHAAAN]

A good number of the general public still breathe through their mouths, believe the earth is flat, and read the daily mail. The idea of educating them on 50kw vs 350kw, charging and etiquette is an up hill battle to say the least.

The only thing necessary for ignorant people to win, is for smart people to do nothing! ? Educate them folks!

Greetings all,

My charging escapades were subpar today (due to people, not EA), and I wanted to get you all's seasoned opinions as I'm still new to this. I have never charged my car at a 350kw station so I ventured to one, and went to a subsequent station out of necessity later in the day. For both occasions, cars with a maximum of 150kw charging capabilities (ID4 and Volvo CW40) were taking the only 350kw stations. I was about to talk to the ID4 owner and he moved, but by the time he moved I was at 60% so changing chargers was a waste of time. The woman in the volvo was at 75% when I arrived and basically told me to kick rocks. She was still there by the time I left, charging at <50kw with her battery at 95%.
For the second occasion, there was only 1 350kw charger available, and another ID4 was there. What made matters worse is I was at 11% and really could've used it, and the car was sat there charging for an hour to the point where the charger kicked the car off, but the owner was nowhere to be found. To add to my annoyance, for both occasions there were 8 completely open 150kw stations.

Is this what I have to look forward to? I'm dreading my upcoming 750mile road-trip later this week if people are this inconsiderate and/or ignorant of their own cars to the detriment of others...

It should be a case of tiered pricing to help solve this. 0-50% lowest price, 50 - 80 medium, maybe 25% higher, 80 - 100 highest let's say 200% higher, it would discourage people hogging charges at really slow rates and encourage them to charge to what they need. It would be good if this was dynamic too so that it kicked in when there was high usage.

I learnt something new today. At the local Tescos I was chatting to a VW owner who pulled up who said there was a group of them who leave their cars on charge at Tescos overnight cycling home on a Brompton as they don't have home chargers. I don't either but leaving a Taycan overnight in a Tesco car ? park isn't going to happen. Some of the early EV adopters are clearly innovative in their quest for charge. I guess that's why podpoint stopped the free 7kw charging at Tescos... Also meant the 7kw would be full, not really in the spirit of community.
