Remove the 25% minimum charge

[Jhenson29]

Serves me right. The only time I've been below 25% so far, my house was out of power.

Well, maybe that could be a solution.

@Silverback, did you try shutting power off to your house until you’re ready to charge? ?

No idea about Octopus, but Ovo is 10p for any time charging. Far simpler perhaps and much more flexible.
Then again, my charger won’t be installed until Monday. So, I’ll soon find out if it is indeed simple.

OVO is currently £0.07 / kWh

Works a treat ensure you have a smart meter in place too as this is a prerequisite.

Has anyone figured out how to use charging profiles but get rid of the 25% minimum charge?

The reason I ask - I arrive home at 9pm, I have about 10% battery left. I want to plug in my car and relax, however my car will then charge to 25% straight away and then it stops and then charges overnight. However I am then not using my cheap rate of 7.5p but 29p to get up to 25%.

I have a wall charger, but I don't want to be messing around with timers on here as we have more than one EV (the other is setup on Intelligent Octopus which manages the charge times).

It is not a big deal, but it does mildly annoy me.

Thanks

Here is a link to a good tutorial=>

Setting is there to protect battery. 10-25% you want to do asap regardless of the rate to protect battery in the long range. Pennies saved here would not be worth the damage to the battery due to car sitting on very low soc for hours. You can always charge the “bulk” over 25% at lower rates and save money on that piece. As much as I hate the inflexible battery charging user interface, 25% forced charge is probably the only rule that makes sense.

I get around this by setting my EVSE (Wallbox Pulsar Plus) to only charge after 11:00 PM when lower rates start. Both the app and car report a charging error but it does start to charge after 11 when the low rates start. This is the error it's giving me right now.

I've heard that with some EVSEs setting a schedule like this prevents the car from charging correctly though. In general, it's best to avoid schedules set at both the car and EVSE so depending on what you have for charging at home, what works here may not work for you.

I'd love if Porsche changed the 25% minimum to 10%, it should be a super easy fix on the programming side and make life for owners on time of day rate plans much better.

The profile in the car is not that great, I control it from my wall chargers. You can use a mixture of both, set a wall charger to come on after 12am and stop at 5 am. then set your car profile to start charging at 00:01

Hello I am new to the Taycan ownership and community. This is my 1st EV vehicle coming from a Range Rover supercharged v8. What does this 25% mean? My salesman never explained this to me? I just plug it in and wait ?‍ can you please explain so I have an understanding.

The Taycan's charging management is based around profiles (which are location based) and timers. There is a "minimum charge" setting in each profile and it isn't obvious what that means. Let's say I have a "home" profile tied to my home that says the best time to charge is between 11:00 PM and 5:00 AM (I do) and a minimum charge in that profile of 40%. If I come home from work with the battery at 35% charge, when I plug in, it will start charging immediately and will continue charging until the car reaches 40%, then it will wait until 11:00 PM and charge to the target I have set in my timer.

In my case, I pay a 3 cent per kilowatt surcharge between 3:00 and 8:00 PM but I get a 2 cent per kilowatt discount between 11:00 PM and 5:00 AM. I really want to avoid charging during the peak pricing hours.

The problem of the minimum charge in the profile is it is effectively saying "There's a minimum range/charge I want and the car should immediately try to reach this minimum any time it's plugged in even if it costs extra to do so."

The minimum makes a certain amount of sense if you're using a 3 KW charger (and it might take a full day for a full charge) but it is pointless if you have a 9 KW or above charger and can fully charge over a single night.

Does that help?

Both the app and car report a charging error but it does start to charge after 11 when the low rates start.

Thanks for reporting this, because I wasn't willing to rely on this. I plugged the car in while the power was still out to the house, because the utility said it would come back on around 2300. When that happened, I was still awake, and went to go check on the situation. There was a flashing red LED near the inside of the driver's side mirror and the car seemed to be "pouting", so I wasn't sure it would keep polling the charger to figure out if it was ever going to get fed.

So I decided not to take the chance, because there was another blackout scheduled for 24 hours later, and just unplugged/replugged it back in to make sure that it knew that it could charge overnight.

So you're saying that there will be a dynamic and automated recovery from that state of affairs?

I am on octopus energy. I got home at 17:00 and plugged in. The octopus app automatically set a charging time of 17:00 to 05:30 as I had set I wanted 85% by 0530. As octopus is driving the charge I may think I am being charged the day rate from 1700 to 2330 but when I check my detailed bill for each day in fact I am being charged the cheaper night rate from 1700 all the way to cut off at 0530. Have a look at the detailed pages of your Octopus bill and you should find the same. The 25% minimum is thus a red herring. If you look at the table in the attached image from a previous day you will see the cheap rate kicking in at 1700 when I plugged in

What state of charge were you at when you plugged in? And what speed charger are you using.

That's some great extra hours

Today I was around 30% when I plugged in. The zappi is max 7kw single phase. I am drawing 4.5kw /hr right now. The picture of a previous charge where I started with a bigger unknown percentage was drawing at around 2.5 per hour. The main point is it is all cheap rate irrespective of time of day.

I get the annoyance with the inflexibility - I really do - but can't stop wondering what's the actual difference in cost.

In your case (in a later message), it seems to be a 5c/kWh swing between highest and lowest cost. Let's be generous and assume a 100kWh battery, which means 10 to 25 SoC is 15kWh, or 75c more/charge.

I suspect the delta is higher across the pond, but not sure if we're talking about 20p, 50 or more? Going with 20, that's 3 pounds additional cost. I can't tell if that's a lot, as surely there is some value to having the car "ready to go asap". (For instance, my home profile has a min of 35% as a "peace of mind" target - most unexpected trips would fall into that range, or have plenty of high speed charging options.)

That bit I know. I was just wondering how you ended up with a 12hr window.

I suspect I use too much generally ?
