EV general discussion

don't you always look at fill and think I'll put £50/£60.. pounds worth in, or a specific litre count, as opposed to dealing with poor pump cut-offs
That’s just weird. Why do anything other than just fill it up? Can’t say I’ve ever experienced a poor pump cut off. It stops when it’s full. Job done.
 
Emailed Ohme about the low charge kw rate as I can't get it any higher :rolleyes:. Not overly concerned as it will charge fully overnight but still want to find out why that is & resolve.
Drove the car today, first time since collecting the car on Monday, but only to my parents house and back home, and must admit it's rather fun but also very relaxing too when just taking it easy. Actually felt a bit annoyed when I had to use the brakes a few times, the regen stops the car most of the car as long as thinking ahead.
 
Have you tried change target to
Max charge so you get the red screen on the app?

I always think if it was that special they wouldn’t have to bribe people to recommend it and adopt it.

I’ve had time to look at the data and you are right, that 5p a day extra a day standing charge totally makes switching daft...

23kWh of the 40kWh was EV use.
 
Yep, tried overriding the plan settings with max charge with both prefer green energy off and also the easy on the battery option. Turns red, still shows 3.7kw. Changed the in-car settings for charging to Max but I have a feeling those are just for the AC options, ie, three pin socket power and AC fast charging. I believe the wall charger falls under Mode 3 and there are no options for that. I'll carry on trying things but will be interesting what Ohme come back with.

The installer noticed it as we plugged the charger in before he left and said it would rise but just hasn't.
 
Someone I saw earlier on a nerdy Facebook Agile group I probably want to leave now said they did manage to call Ohme who upped the rate remotely. Hope they can help you out.
 
The P2 doesn't have a heat pump though so how would it heat up I only drove 5mins to the charger dropped someone to the train station then went to the charger.

The heat pump can recover heat energy from the battery and it’s not the same thing as battery thermal management. So the battery on your Polestar has a heater and a cooling system. When it’s too cold, the battery heater kicks in, when it’s too warm (like while it’s being FAST charged), the battery cooling is used to keep the battery in the optimum temperature band for longevity and charging speed. It also makes the car more consistent in terms of range and performance.

I used to have battery prep on both my old Tesla’s. Model S uses it to get the car ready for launch modes and the Model 3 uses it to get the battery warmed up as you drive to your next charging stop.
 
Heat pump can also recover heat from the air...

The heat management system doesn’t need a heat pump to take heat from a battery. Good sentiment there though.

I’m still working out FAST and RAPID. As I think we are in a situation where 7kW to 22kW is considered “fast”.

It depends on the company selling the energy or chargers I think. Polar certainly use the 7kW definition for fast and anything over 50kW is rapid. Then the 150kW suddenly reverts to ultra-fast rather than putting more weight on the rapid term. The numbers don’t lie though. 7kW doesn’t feel very quick at all...
 
Indeed Agile only works if you don't need to charge your car very frequently, and can take advantage of the dips when they happen. Also being able to time-shift other power heavy things like tumble drying, or hot wash cycles. dishwasher use.

It works for us as a family, but we have very light use between 16:00-19:00, and tend to only charge the car once a week at most, and even less infrequently due to lock down.
 
We're weighing up going EV at the moment, 80% of our 12k annual mileage is short journeys at home but we travel down to see friends about once every 6 weeks (c.350 mile round trip). Is there a good map of chargers anywhere that we can use to see what the journey would looks like? e.g. Where we'd need to charge on the M6/5 for instance, and how much it costs.

ABRP (A Better Route Planner)

You might find it surprising just how many there are :)
 
350 miles round trip isn’t too disruptive if you can grab some juice while at your destination. Even a couple of hours on a 7kw post will make a big difference in the total travel time. 3 pin socket would still be worth it for a few hours if nothing else.

Yeah, seems fine - just like to see what the different would be on the various 50,60 and 80kwh cars.
 
Efficiency + changing speed make just as much of a difference than battery pack size.

It is, as you say, within efficiency but I find that all the BEVs I've had have been ludicrously inefficient once you get up to motorway speeds. As an example, my current Kona normally does 4.5 miles per kW (14kW/100km) which gives you a realistic usable range of 230 miles in mixed A-road driving. That's excellent. Completely usable. Then keeping up with the traffic on the motorway (70-ish mph) it drops off a cliff to 2.8 miles per kW (18kW/100km) which translates to a real range of 143 miles at the first stop (start off with 100% SoC) and 108 miles when you rapid charge back up to 80%. That is pretty horrific when you start doing your routing on ABRP and you have to stop so much more often.

And I don't like to drop my SoC below 20% at the end of a stint because you really can't guarantee a charger will be working or unoccupied and you might need that last 35-40 miles of range to get to the next working charger.
