I can confirm on my OH 3.4 M6 setup as well. Looks like it is the case since yesterday. The trace shows, that already the first call to the BMW API fails. Also all others after this one fail as well (500 - Internal Server Error).
HTTP Error https://cocoapi.bmwgroup.com/eadrax-chs/v1/charging-statistics?vin=WBXXXXX¤tDate=2022-12-13T23%3A38%3A12.000344 - 400 - Bad Request{vin=vin=[WBXXXXX], currentDate=currentDate=[2022-12-13T23:38:12.000344]}
My OpenWB Wallbox can read the data via API. So looks like a specific issue in OH. May be some HTTP client specific things like headers are needed?
