EV general discussion

People also have unrealistic expectations of fast charging. Most cars will not sustain anywhere near their peak for more than a couple of minutes - the more charged the battery, the slower it can take on more.

Yeah, the charge above was started at 10%, it had dropped to 58kw by the time we were ready to leave 30 mins later

maybe trying to understand whether people have made efficient use of chargers (tangent ? discussion was about new chargers - so, will they be exploited)
I could repeat the practical issues in my own words - but if links/videos perfectly explain the issue might as well link them -

Yeah. I also found out the other day that superchargers use water-cooled cables so that the copper doesn't have to be so thick that the wire is unmanageable
250KW @ 400V is 625 amps!

Indeed,

But it doesn't cool the CCS interface, does allow the cable to act as a heatsink and of course its only the EVSE side of the HV conductive path thats cooled.
 
What’s great about the Nero (and Kona) is that they are super efficient.

So while its charging speed on paper is pretty low, the amount of range you actually get back for the time you are plugged in is pretty good. It’s not that far off cars which charge much much faster.
 
Not efficient at turning electric into power though ;). They are tiny cars. Any power train will do well…

is 270Wh/m super efficient?
 
Question regarding Intelligent Octopus.

I plugged my I Pace in last night and because I can't control the car via the Remote app I set the Pod Point to charge between 23.30 and 5.30.

The car has charged but the electic useage cost overnight isn't on the lower rate of 7.5p - Not sure what the rate was that it charged me but definately higher than 7.5p.

If the Pod Point charger schedule interferes with the IO schedule, would it stop IO from using the lower rate?

Next time I charge I'll turn off the Pod schedule and leave IO alone, see if it makes a difference. It's surprising how much of a pain it is not being able to control the car charging via the app.

How do you know what you were charged?

IO is always at 7.5 from 23:30 to 5:30, regardless of a car being plugged in or not. The IO cheap hours extend outside that window if necessary to meet your target.

Pod Point doesnt work with IO, it relies on the car API handshake to enable the lower rate.
With regards to the Kona - firstly i think reported consumption has a massive industry varince, im sure some cars only report driveline usage and not full car and then its the battery use rather than whats come from the grid and wall charger. Hence China NEV homoligation now includes AC charger efficiency.

Kona is a small car, FWD on little wheels. Its just physics.

Yeah, I was very pleasantly surprised at the average 3.7 mi/kwh at motorway speeds!

Not quite as simple as that. Compared to the ZE 40 I had before, which was a smaller lighter car, it's far more efficient!

Really silly q but you sure you aren't looking at total consumption? 7.5p kWh but it could squeeze in 2kwh per hour hence it'd show 15p for that hour.

Not sure what the implications are of that. What would cause the API Handshake not to trigger the lower rate?

Would it be linked to why I can no longer control the car with the App? I have to wait until it either self sorts or Jag dealer will reset TCU but not until July.

The car stopped communicating at the same time I tried to set up IO.

I took a pic of our smart meter last night and checked this morning and the difference just seemed much higher than expected. I think IO must have had some control - or may have just been working - because I've set IO to cut off at 90% and it did do that. IO is the only place where I specified the 90% limit.

Aerodynamics ! Smaller car less drag. I got 3m/kWh in a ID buzz at 70-75mph which surprised me more!

My cupra is about 3.7 in this weather and will do as well as 5.4 on my commute. I think the MEB platform is pretty efficient in real world based on the last few weeks of trying many EVs out.

Maybe I should try the Kia soul EV. Just need a paper bag

What is efficient is the context of ‘efficient use of chargers’?
