Continuous plan stops and restarts

[cpe35]

Describe the bug

Overnight the planer was set to charge the car. Despite the continuous option enabled, the charging was not continuous. At first the car was only charged for 15 minutes, then the charging paused for 45 minutes and started again.

The logs below show that for the first and second charging period the planer calculated the same average cost of 0.311 euros/kwh.

Steps to reproduce

The following was observed:

1. The planer was set to charge a car until 7:00 with the continuous option enabled.
2. At first the planer estimates to start the charging at 4:00:

3. The charging starts as planed:
   INFO 2026/01/31 04:00:40 start charging ->
4. Four minutes later a new start date (5:00) is calculated:

5. The charging is stopped at 4:15

6. Then the charging starts again at 5:00
   INFO 2026/01/31 05:00:30 start charging ->

What type of operating system or environment does evcc run on?

Linux

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

evcc version 0.300.7

[andig]

The charging is stopped at 4:15

Unfortunately your report is missing a detailed log file. Without log, we don‘t have the information for diagnosing the issue described. See https://docs.evcc.io/docs/faq#wie-kann-ich-ein-logfile-zur-fehleranalyse-erstellen.

[cpe35]

Ok, here is the complete log file
evcc.log

[iseeberg79]

I believe you've identified a special edge case. The planner prefers the later start when costs are equal (<=). During charging, the remaining duration decreases, a later equivalent window is found, and the plan jumps. There is a protection to continue charging until the current slot ends but none to avoid such jump. Result is a new continues charging plan starting later to complete required charged energy in time as an effect of the floating plan optimization.

[iseeberg79]

@andig if we want to fix that it must be added for the loadpoint_plan - an idea would be to compare average costs and continue charging on same costs or to just continue if we are already charging?

loadpoint_plan.go ~200

		case strategy.Continuous && planStart.After(lp.clock.Now()):
			lp.log.DEBUG.Printf("plan: continuing- later plan start %s would interrupt continuous charging", planStart.Round(time.Second).Local())
			return true

[cpe35]

Thanks for looking into it!

I just noticed that the described issue has already happened before with shorter pauses. Maybe the relevant logs are helpful:
evcc1.log
evcc2.log

Especially in the second log file the pause is only 20 seconds and the estimated average cost jumps from 0.327 to 0.326 and than back to 0.327 again:

[andig]

@andig if we want to fix that it must be added for the loadpoint_plan - an idea would be to compare average costs and continue charging on same costs or to just continue if we are already charging?

loadpoint_plan.go ~200

		case strategy.Continuous && planStart.After(lp.clock.Now()):
			lp.log.DEBUG.Printf("plan: continuing- later plan start %s would interrupt continuous charging", planStart.Round(time.Second).Local())
			return true

Fix what? It just becomes a shorter but still continous plan.

[iseeberg79]

yes and no - it's a little shorter, and has a gap (45min) now. Not resulting in a continuous plan finally. Need to change perspectives: full charging session is not continuous as the planner in the end has created more than one continuous window. The new logs are showing the same, plan jumps because of floating optimization. There is another chance to fulfill the energy demand at a later window. We should think about to give a current continuous plan in execution priority as the next plan cannot be cheaper but at equal costs only and being later.

[andig]

yes and no - it's a little shorter, and has a gap (45min) now.

Really, it is a new continuous plan since planning assumptions have changed. I don't think we should enforce continuous charging in this case. Or should we? What happens when we try to change to x% with preconditioning? When the plan gets shorter you'll either overshoot the x% or can't charge for preconditioning.

I'd keep it as is, maybe make clearer that "continuous" is a relative term. Wdyt?

[andig]

@iseeberg79 the 13min pause should have been skipped imho. Is that one really paused? The others are all due to the charging speeding up more and more combined with preference for later start even if costs are equal.

What I find strange is that the plan end jumps around by 15min- I would have expected that to be fairly stable.

[iseeberg79]

Yes, you are right - and I also would expect the end to be stable.
Every short pause to restart within 15min is avoided and charge-end is post-poned until slot end. There is only one critical situation:
