Consumption with live OBD connect too optimistic


Avatar

On the Skoda citigo eiV with OBD connect, the estimated arrival SoC is way too optimistic. Resetting the consumption doesn't help.

Current standard ref cons for the Skoda CITIGOe iV 2020 (alpha) is 146 wh/km @ 110 km/h. This includes added margin and 136 wh/km is therefore not too low.

A too optimistic arrival SoC should most likely be caused by other parameters. If you'd still want us to investigate this please post a link to a plan where you feel we're too optimistic. You may generate a link by clicking 'share' once you've created a plan.

Thanks for your reply.
I checked my drives. The values in the export match the real SoC at start and arrival.
What doesn't fit is the estimated consumption from the start. Last trip yesterday it guessed 45% from start to 29% at arrival. It then continously decreases the arrival SoC until arrival at 24%. Weird is, that the reference consumption seems correct. Is the algorithm to blame?
Don't know how to fulfill your second request (charging the car). Should I charge the car and monitor it with Abrp?

Yes please charge the car and read the data with ABRP and make a screenshot of the car details page (the ⚙️ icon behind your car in settings) where it shows the values like power and voltage. Then we can check if there is a mismatch between real power and power provided by OBD.

Can you please check the values in mydrives and check if they look reasonable?

The easiest way to confirm that you get the right values is to start charging at a specific speed (e.g. 3.6kW) and then check the data in the app. Please try this and make a screenshot so we can see if anything looks suspicious.

So did you charge with 6.1kW? Looks like 2P (max 7.2kW). If that value is close enough to the real value then at least the OBD values look correct.

It's connected to a 11 kW Wallbox. The citigo charges with 2P, yes. I don't doubt the gathered values, the estimation is unreliable.

To amend, the reference value is too low. I use 161 Wh/km, ABRP estimates 136. Does it mix gross and net capacity of the battery? The SOC Display of the citigo refers to the net capacity, which should be the same for ABRP.
