MIsmatch between In and Output

[ahmetiflorenc]

Hi, i noticed when charging my EV with Min+PV that i am getting a mismatch between in and output. The UI also shows 1,5 Kwh that cannot be allocated to the input.
What i also noticed is that the house consumption is at zero and that only charger and battery are consuming.

I am a lost and would appreciate any help. Thank you!

house consumption is calculated based on the measured values.
Do you have any other input, that is not configured in evcc?
Are you sure, that the chargepower is correct? (ZOE doesn´t like small currents in 3p)

[ahmetiflorenc]

no, there is nothing else. I have PV, Battery and grid. The Chargepower value is delivered by the wallbox (Wallbox Commander 2). Our Zoe is offline.

What seems odd is, that when the EV is charging there is no powerconsumption "Verbrauch". As soon as i turn EV charging off, "Verbrauch" is back.

So it seems that EVCC can not calculate the "Verbruach" while EV is charging.

But again this is only the "out" side. The Power that is going in is always lower than the power going out. 1-3 kwh less than outgoing power. so either ingoing power is wrong or outgoing. Everything displays correctly as long as i don't charge my EV

[VolkerK62]

What seems odd is, that when the EV is charging there is no powerconsumption "Verbrauch".

That is, because "out" is bigger than "in".

Everything displays correctly as long as i don't charge my EV

in that case, the charge power seems to be wrong

Our Zoe is offline.

not really [lp-1 ] ERROR 2025/04/29 10:41:09 vehicle soc: unexpected status: 403 (Forbidden)
But it is not configured as "offline"?
(Nothing to do with this problem)

[ahmetiflorenc]

ok, worng charging power could be it but how does it explain, that "Verbrauch" is at zero? There needs to be something that allocates all calculated output to the charger which is wrong. I thought maybe someone else also expirienced that kind of behaviour.

I tried to connect the Zoe but the connected services has expiered so it does not get any data from the car. That is the 403 error. My Wallbox also cannot read the SoC.

[VolkerK62]

"Verbrauch" = pv power + grid power + battery power - charge power
If it is negativ, it is displayed as 0

[VolkerK62]

There needs to be something that allocates all calculated output to the charger which is wrong.

The calculation of the charge current ist based on

• battery power (depends on the battery settings)
• grid power
• former charge current

Here are 26W battery charge power and 38W grid surplus.
-26W + (-38W) = -64W site power
So there are additional 64W charge power available and the charge current is increased from 8.13A to 8.22A.
