Can the BYD Seal U DM-i provide a charging history with kWh data?

I can’t find what you describe on my BYD app but I get my charging history from my Wallbox home charger app: https://preview.redd.it/8nppyaqu3gmg1.jpeg?width=828&format=pjpg&auto=webp&s=bc1d69b91cc6a69831324c2250ac06e32400e093

dash screen has kWh charged and you can reset it ss you wish (monthly)

Thanks. I’m attaching a photo of what I can see on my side, here https://imgur.com/a/1sxmkvf and I honestly do not seem to see that value. What I do see is a total linked to a field called “external charging capacity”, but my understanding is that this should refer to VTOL / Vehicle-to-Load, meaning power used to charge external devices through the vehicle’s charging port. What confuses me is that this value is above 0, even though I have never used the car to charge anything externally. So unless I am misunderstanding what that field actually means, I do not see a clear kWh charged into the car value that I can reset monthly. Am I looking in the wrong place, or is “external charging capacity” supposed to mean something different on the Seal U DM-i?

i really think its labeled wrong. Mine included that says VTOL on central screen at picture1. https://preview.redd.it/809egtubfomg1.jpeg?width=4096&format=pjpg&auto=webp&s=ae5ffd66955f135d92a709fcc0c2642a69595b17

But if you fin this phyaical button and navigate to this info on driver screen that says plug in charge you will see the same value https://preview.redd.it/0sqpdu7jfomg1.jpeg?width=2304&format=pjpg&auto=webp&s=3587d3ce0c342c826c5f6b3593838cc5cb613283

So, do you think that label is completely incorrect for the value being shown? In that case, I’ll try resetting it to zero and compare it with the readings from the other two devices I’m using, just to verify whether it could actually be the correct figure. Thank you for the info.

yes, that label on central screen is wrong. I usually reset all data every tank fill up and this number get zeroed together. As I charge up my battery it get add up. If the measurement is actually right I really dont know. I think wvery different meter you put into the way will get you a different Reading. You gotta analyse and decide wich one have greater accuracy. I would not think the car is the most precise as it will gauge "how much got in", but all process must have some eficiency loss so you should measure how much was actually spent to put that X ammount inside the battery.

If it really takes 14.5 kWh from the wall to end up with only 8.6 kWh shown on the dashboard, that would be extremely worrying. The outside conditions don’t even justify such a loss. The lowest temperature last night was around 6°C, so the battery shouldn’t have needed any significant pre‑heating to avoid cold‑related limitations. On top of that, the energy meter *before* the charger recorded 33.3 kWh consumed in these first two days of the month, which is noticeably different from the sum reported by the charger itself (14.5 + 15.2 = 29.7 kWh). In that case, what you’re saying could make sense: maybe it really took 33.3 kWh from the grid to deliver 29.7 kWh into the car, which would mean roughly a **16.2% energy loss** during charging. That wouldn’t be impossible (well, *if* both devices were calibrated correctly). But right now, the discrepancy between the dashboard, the charger, and the external meter is too large to ignore, so something in the chain is definitely not reporting accurately. 😭 **(Info sourced via AI):** In my case the VTOL value went from 0 to 8.6 kWh overnight even though I have **never** used Vehicle‑To‑Load. On BYD cars this VTOL counter doesn’t strictly track only energy delivered to external devices. It often increases during normal AC charging because the system uses it to log internal energy handling (conversion, battery balancing, etc.) rather than actual V2L output. So that 8.6 kWh doesn’t mean the car “powered” anything, it’s just how the interface reports some of the energy processed internally during the charge. So, it's pretty useless 😅

Sorry for the delay. I had to drive the car for the rest of the week to drain the battery and charge it up again to compare what the car reads to what my charger shows. In the previous reply I had charged already 59.2 kWh. After charging from 24% to 100% the car plugin meter says 74.9kWh, so 15.7kWh increment. My charger says that in this charging session was 15.58kWh. So even my assumption that the car would gauge less energy than an external meter was wrong. In my case the difference was minimal. My charger is not like a wallbox. Is just a portable one, 220v 32A max with that industrial outlet connector.
