Define max Amps on a phase and prioritize car charging

[hfvdv]

It would be nice to prioritze the charging of the car over the battery when there are competing times. For example tonight between:
03.00 and 06.00 the Car will charge with max of 16 amps
03.00 and 05.00 the battery will charge with 10 amps

I have 3x25 and it would be nice to indicate that:
Base amps is for example 3 Amps
Leaving 22 Amps for Battery and Car Charging
16 Amps will go to car as that has priority
Leaving 6 amps for battery charging (1-fase) until car is full. ( so the battery is throttled to 6x~230 approx 1400w ).

my two cents :-). Let me know if there is anywhere i can help or support.

I have a few days ago uploaded in the develop branche a new test version where you can define a maximum (in kW) for your grid connection.
I would be glad if you will test this version for your situation and I am curious for the results.

wonderfull. will do and let share my observations and comments.

Hi Coen, i am probably wrong. I used the developer version and adjusted maxpower to 15 just to keep a bit of a margin in the beginning. in the attached screenshot ( text also provided below ) i know see charging occuring from 00.00 - 03.00 and the discharging again from 03.00 to 06.00 to assist i expect the ev being charged. This to me appears not to be economical. prices slighly more expensive from 00.00 to 03.00 as opposed to 03.00 to 06.00 H  uur bat_in bat_out cons prod base boiler wp ev pv_ac cost profit b_tem 17.00 0.00 1.20 0.00 0.06 1.11 0.00 0.00 0.00 0.00 0.00 -0.02 20.00 18.00 0.00 0.22 0.85 0.00 1.07 0.00 0.00 0.00 0.00 0.25 0.00 20.00 19.00 0.00 0.00 1.05 0.00 1.05 0.00 0.00 0.00 0.00 0.30 0.00 20.00 20.00 0.00 0.00 1.10 0.00 1.10 0.00 0.00 0.00 0.00 0.30 0.00 20.00 21.00 0.00 0.00 1.03 0.00 1.03 0.00 0.00 0.00 0.00 0.26 0.00 20.00 22.00 0.00 0.00 0.88 0.00 0.88 0.00 0.00 0.00 0.00 0.22 0.00 20.00 23.00 0.00 0.00 0.72 0.00 0.72 0.00 0.00 0.00 0.00 0.17 0.00 20.00 0.00 1.13 0.00 1.75 0.00 0.62 0.00 0.00 0.00 0.00 0.37 0.00 20.00 1.00 2.20 0.00 2.80 0.00 0.60 0.00 0.00 0.00 0.00 0.57 0.00 20.00 2.00 2.20 0.00 2.83 0.00 0.63 0.00 0.00 0.00 0.00 0.56 0.00 20.00 3.00 0.00 1.20 10.00 0.00 0.70 0.00 0.00 10.50 0.00 1.78 0.00 20.00 4.00 0.00 1.26 10.00 0.00 0.70 0.00 0.00 10.56 0.00 1.73 0.00 20.00 5.00 0.00 1.20 10.00 0.00 0.63 0.00 0.00 10.57 0.00 1.74 0.00 20.00 6.00 2.20 0.00 2.88 0.00 0.68 0.00 0.00 0.00 0.00 0.59 0.00 20.00 7.00 0.00 0.00 0.74 0.00 0.74 0.00 0.00 0.00 0.00 0.17 0.00 20.00 8.00 0.00 0.00 0.94 0.00 0.94 0.00 0.00 0.00 0.00 0.25 0.00 20.00 9.00 0.00 0.00 0.99 0.00 0.99 0.00 0.00 0.00 0.00 0.27 0.00 20.00 10.00 0.00 0.00 0.90 0.00 0.90 0.00 0.00 0.00 0.00 0.25 0.00 20.00 11.00 0.00 0.00 0.72 0.00 0.76 0.00 0.00 0.00 0.04 0.20 0.00 20.00 12.00 0.00 0.00 0.44 0.00 0.78 0.00 0.00 0.00 0.34 0.12 0.00 20.00 13.00 0.00 0.00 0.60 0.00 0.83 0.00 0.00 0.00 0.23 0.15 0.00 20.00 14.00 0.00 0.00 0.83 0.00 0.89 0.00 0.00 0.00 0.06 0.22 0.00 20.00 15.00 0.00 0.00 0.90 0.00 0.98 0.00 0.00 0.00 0.08 0.24 0.00 20.00 16.00 0.00 0.00 0.94 0.00 1.05 0.00 0.00 0.00 0.11 0.25 0.00 20.00 17.00 0.00 1.20 0.00 0.11 1.11 0.00 0.00 0.00 0.02 0.00 -0.03 20.00 18.00 0.00 1.20 0.00 0.13 1.07 0.00 0.00 0.00 0.00 0.00 -0.04 20.00 19.00 0.00 0.00 1.05 0.00 1.05 0.00 0.00 0.00 0.00 0.30 0.00 20.00 20.00 0.00 0.00 1.10 0.00 1.10 0.00 0.00 0.00 0.00 0.31 0.00 20.00 21.00 0.00 0.00 1.03 0.00 1.03 0.00 0.00 0.00 0.00 0.25 0.00 20.00 22.00 0.00 0.00 0.88 0.00 0.88 0.00 0.00 0.00 0.00 0.20 0.00 20.00 23.00 0.00 0.00 0.72 0.00 0.72 0.00 0.00 0.00 0.00 0.14 0.00 20.00 Totaal 7.73 7.47 58.66 0.30 27.34 0.00 0.00 31.63 0.89 12.16 -0.09

Can you send me the graph of the calculated results?

[corneel27]

When you choose the strategy "minimize costs" then is the calculated solution always the most less expensive (within the given boundaries).
In your situation your consumption is maximized at 10 kW (right?). Your car is priviliged for loading with 10,5 kW and your baseload is 0,63 - 0,7 kW. So the algoritme had no other choice than take energy from the battery.

I stay within my maximum. This is how my consumption was calculated for today:

Cheers, Cees

[hfvdv]

Hey Cees, thanks for the response and makes sense. i indeed set it to 10 for max consumption. I changed later to 15 which indeed appeared to resolve the issue. I will change it to 13 ( as i typically have 3 amps on fase 1 with the others on 0 during the night ). I will let you know how it goes. Expect to be able to share some new results after 13.00 today.

Sorry, but I didn't see/receive(?) the attachment.

[hfvdv]

Hope this works. assumed it would be visibly when replying be email.

[corneel27]

Thanks, looks good indeed!
Perhaps you can show this kind of graphs in the sessy topic of tweakers?

[hfvdv]

Will do. Will evaluate for a couple of weeks and share my experiences including supporting graphs if that helps the community.
