EV general discussion

Yeah thats the suprise when its been rated at 300kW rather than expected 150kW, prob 920V substation feed from the 3.2MV transformer that went in.

All fed off a single power unit so it can do 300kW when only 1-2 in use?

Many of these HPCs are headline numbers, like the Gridserve ABB 350kW relies on paired cabinets and you get 175kW when both posts in use.
 
It’s a very similar set up to a tesla supercharger. In thoery you can max out a cabinet with a couple of cars but practically speaking that doesn’t happen often.

The nice thing about Kem power is that the charger gives you a lot of information including if the power delivery is currently charger or car limited. You can scan the QR code on the screen and get it on your phones browser in real time.
 
i am new to EV owning so perhaps i am wrong but...... i assume simply by driving the car for an hr would get the battery to peak condition wouldnt it ? if so for most people pre conditioning would not be an issue, assuming you only use these fast (and expensive) chargers on a long journey.

i know if it were me i would use them when going on holiday. i would leave home with full battery slow charged at home for pennies, and then would use the CCS charge point when my battery was getting to the 25% mark if i still had a fair distance to go....... (then on arriving i would hope there would be a slower - and cheaper - chargepoint to use when parked up.)

but i may be wrong.

My car preconditions for planned charging even on long journeys. A lot will depend on driving conditions and ambient temperatures of course. And only really necessary to get the absolute best charging performance.
 
I've got an issue with my I Pace.

Had the Pod Point charger installed yesterday and ran the Intelligent Octopus app - not sure exactly what this does.

I noticed after an hour the charger hadn't stopped so I disconnected the cable.

From the moment the cable was plugged into the car, the remote app won't update. I've read that you may have to pause charging to allow IO to do its thing but I can't do anything via the remote.

Have tried various things referred to online but no dice. Will give it a couple of days and if no joy wil contact my local Jaguar dealer and see what they say.

Some cars don’t bother in the interest of minimising energy consumption. Tbh after an hour of driving and 15-25c ambient most cars will charge fast enough.

It’s not needed as often as people think either. Destination/home charging is the answer. Fast chargers are for top ups. Not cold charges
 
Preconditioning I’d actually heating the battery to 35-40c. So it should be seen as a conscious thing. Not the norms, otherwise it’s like a Tesla model S warming the battery to ludicrous mode all the time. Wasteful.
 
Just spotted the superchargers at Tebay services have been upgraded from 8 V2 (150kw shared between 2 stalls) to 12 V3 250kw stalls.

That should help significantly with those bank holiday queues there were at Christmas last year.

I’m not sure how many cabinets there are serving those 12 stalls but it’s usually 3 or 4 stalls per cabinet and those cabinets being rated for 500kw-1mw. They also have a DC bus so power can be shared between cabinets depending on loading. It’s pretty rare they are saturated in reality but it is technically possible.

There should be 4 non-tesla chargers going up over the next few weeks where the old V2 stalls are located and 6 on the other side of the M6.
 
Pretty sure the eNiro doesn't precondition, but had no problems charging near max speed after a couple of hours on the motorway at 70mph

so you've used 50 ? 150KW ? chargers and soon after plugging in seen the reported charge rate rise to those levels,
( the video I linked above had shown people plugged in and paying for 250KW chargers, but only taking 50KW)
 
If you used chargers you would know the price difference for a kWh simply doesn't change enough to care what rate it is.

But then jpaul is a talker not walker, we now know he hasnt got an EV.

PS. A reported charge rate can only be that after the charging has started not before.

This is on a 100kw charger, 1 min 36 seconds after plugging in:

Car has a theoretical max of 77kw

The charging curve is available here if you're actually interested rather than just trolling.

That's because it can't do a REALLY fast charge, only 80Kw or something on the Niro.

True, but surely the same still applies - it's not going to charge to it's full potential if it's not in the correct conditions? (Happy to be corrected if it doesn't work like that)

He’s on another planet. Just goes off on tangents posting videos and links he doesn’t understand and I’m not sure why. Is he trying to help educate people or just cause confusion?
 
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.

Tesla have just started implementing a new battery in the Model Ys made in Germany, which is much better at this kind of thing:
